Preferred Solution: 250GB SSD M.2 not recognised by bios or OS

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

I have looked through previos questions but couldn't find a solution. I have a 250g USB driven HDD not recognised by ny PC. I used the HDD on my TV so I think it will probably need reformatting. When plugged in it appears in Disk Management but without a drive letter and when I right click on the drive most of the options, including allocate letter are greyed out. Any solutions?

Answer:USB 250GB HDD not recognised by PC

I would recommend PartedMagic, it is now paid for software, but at only $4.99 it is a sound investment. Download it, burn it to a cd or put it on a USB stick and boot from it.
Have the suspect drive connected and PartedMagic should be able to see it and it will enable you to format the drive, whatever the existing filesystem is.

I have a SmartDisk 250 gb external harddrive that seems to not be recognised on my computer (vista premium os). I plug it in, it does not go into the usual "installing new hardware" thing, but I can go into the device manager and the hardrive is listed as being on the system. But, in the device manager, it is named "Samsung SP2514N". I downloaded the drivers for that model and installed, still have no access to it. the device manager gives the following info on it:
Disk: Disk 3

thats all I have on it. any help on accessing and using this harddrive would be greatly appreciated

I've recently installed a new MSI KT3 Ultra motherboard, and a new 250 gig western digi hard disk. Now, in the bios it recognises that the drive is 250 gigs however when i setup xp it only recognises it upto 130 gig and won't see the full size of the drive.I know 48-bit LBA mode addressing needs to be enabled and as far as I can see it is turned on in the BIOS and as i say, the bios recognises it as 250 gig but windows doesnt and only shows it as 130 gig.Any ideas?

Hi, I'm new to the DIY PC World and urgently need some help.
My hard disc is a Samsung 250Gb disc and it is recognised in the BIOS. As soon as I attempt to install Windows XP, when formatting, it only recognises 127Gb. I installed it anyway and ran some Windows updates from the MS site, thinking this might fix the problem. It didn't. I also accessed the Disc Management window (saw this advice in one of your threads) to no avail: it says that this device is working properly, although only showing 127Gb. If this is important, my CPU is an Adlon 64 Venice 3000+.
I'm grateful for any advice any of you might have.... !!!

Hi there, I've got a 250gb maxtor HD and it can't be detected in bios or something is wrong. WHENEVER its connected (either on its own or with another drive), it says "error loading OS".
(PC boots fine with my other Maxtor 120gb HD)

On some sites it says to set Bios HD Access to LARGE instead of auto/lba etc

BUT - my bios doesnt show me such a setting when i go into HD config screen. I know what screen it should be on, but believe me, there is no "large" option for HD access.

Motherboard = MSI MS-6567

Can someone pls help me?? Thanks so much


Answer:BIOS won't recognise 250gb Hard Drive

Well, error loading OS only shows that it can't load an OS. Do you have an OS on that drive?
At bootup, your BIOS should list the drives it detects. Do you see the Maxtor in the list (next to the optical drive)?

That's a rather old motherboard. It could be that it simply does not support hard drives larger than ~130GB. And I can't see a BIOS update that would fix it either.. You can try updating to the latest BIOS and hope that it fixes the problem of course.

I had a password locked HD(30Gb), that I finally gave up on. I purchased a 250Gb replacement drive. When I go into the bios to check to see if the system detects it, it show 137Gb, when it did not show anything with the locked HD. I also check to see if there was a bios update, but there was none, just the same as what's already on my 1100. I thought I'd try to use the new drive, while I wait for another replacement, it started to format at 250Gb.

I just wondering why it shows 137Gb. I know this is an issue with some older bios and P3 systems, but I did not expect it with a P4 system.

Anyone else experience this? Any problems if I keep the 250Gb installed, or should I order a 120Gb.



Answer:New 250Gb showing 137Gb on a Dell 1100 bios

Usually this problem is caused by formatting the drive with a verision of Windows XP that has no Service Pack, Service Pack 1, or Service Pack 1a. None of those will format higher than 137 GB.
If you switch to an install disk with Service Pack 2 or Service Pack 3, you can format up to 1.5 Terrabytes without problems.
Alternately, once you format at 137 GB, use a partition editor such as Ghost, Partition Magic, Source Forge, or Acronis (I recommend Acronis)... to extend the partition to the full size of the hard drive.
Either way, you have a cost.

Recently bought Athlon64 3200+, Gigabyte K8NF-9 F11, 1GB RAM & 250GB SATA seagate hard disk. The problem here is that the BIOS (Award Modular BIOS v6.00PG) recognizes the harddisk to be only 130GB. Does Gigabyte K8NF-9 supports SATA 250GB hard disk or its's something I've done wrong? Pls help me out here. Thanks.

Answer:BIOS can't recognize 250GB SATA hard disk

I had a similar problem, I thought it may apply to you.

When I first installed my XP Pro on my system with a new Seagate 250 GB HDD, XP created the C: drive at 125 GB, basically cutting the disc space in half. The rest was just unformatted.

Go to "disc management", and you might find your missing 120 GB in unformatted space.

I updated the bios after I had notified from Toshiba about the Bios v3.50. The process was done by the Toshiba Utility software, and after the reboot there is "Password =" on a blank screen and it not recognise my BIOS password, writing "Not certified".

I have also tried the HDD password but no luck.

What can I do now?

Answer:Satellite Z30-A-12R BIOS password not recognised after BIOS upgrade


Before trying to update the BIOS, all passwords should be removed!
BIOS password can be removed by authorized service provider available in your country.

But the unknown HDD password cannot be removed anymore.
In such case the HDD isn?t accessible and cannot be used.

Sorry mate but in my opinion you have only one chance to get the BIOS password removed; you need the ASP assistance.

This one has me scratching my head.

Turned on the computer and the bios tells me Bootmgr is missing. Ah! panic, looked in bios and one of my drives is not recognised which happens to be the O/S drive. I opened up the computer and re-seated the Sata connections and went back in to the bios - the drive is still not recognised, however, it's there in the boot order section as an IDE not Sata drive...A bit weird.

I select that drive as the first to boot and the O/S loads with out a glitch. My question is how can the O/S run if it's not recognised by the bios?

Hi everyone, this is my first post on tech-forums. I hope I am at the right place.

The problem I am facing is regarding my Sony DVD RW. I own a Compaq machine with the following config at present:
OS: Windows XP Professional SP2
CPU: Intel Pentium 4 524 3.06 GHz
RAM: Total 1280 MB (2 sticks; 1024 MB, 256 MB )
Motherboard: Gigabyte GA-8S661FXM-775
BIOS: Award S/w international, v F7a
HDD: Western Digital Caviar 250 GB
OD: Sony DVD RW AD-7240
Audio: Realtek AC'97

It came with an IDE HD and an IDE CD RW. After some time I installed the SATA DVD RW in one of the two SATA ports. Everything was working fine and I could boot from my DVD RW. Recently my IDE HD went kaput. I replaced it with a SATA HD (WD Caviar). I had to reinstall the OS in the new HD. At that time also I could boot from my DVD RW. But last week when I tried to install Linux by booting from a live DVD, I couldn't. The BIOS is not showing the DVD RW although its working fine in Windows after booting. I have removed my IDE HD and CD RW. Please help me out.

Answer:DVD RW not recognised in BIOS

Hopefully this qill put you back on the right tracks, with your default hdd that has xp on it make that Raid 1
Take you other DVD-RW drive and put it on raid 3, forgive me if thats wrong, but I dont have a picture to go by with your mobo.

Next, look at your bios IDE and raid configuration setup,if it ask you which mode you want, raid achi or ide...
Tell it you want ACHI mode and save your settings, let it do a normal restart, if your windows boot logo comes up great!
If not it will show you which partition you want to select, windows or linux ?

Let us know what happens later on.

Ok. I've got a GeForce 6800GT card in my computer that has been reliable for over a year now. I'm running WinXP Pro and a gig of RAM.

I shut my computer down; left it for an hour and then started it again. BIOS showed up and then the strange stuff started to happen. The monitor went into standby mode and was blank.

So then I restarted and Windows recognised that I didn't have a successful boot up. I then loaded with "Last Known Good Configuration". The windows load up screen appeared and scandisk ran in which it found a few corrupt files and indexes. Then the computer restarted automatically and the "Last Known Good Configuration" screen showed up again. I selected it again but this time the monitor went back into standby mode again. I did a hard reboot and this time....not even a BIOS! Also a audible single beep during start up.

The computer boots up fine because I can hear the Windows load up sound. But still a blank monitor. I tried to attach a different monitor but to no avail. I'm starting to panic now. A Nvidia GeForce 6800GT is a v. expensive card. Please tell me I'm not going to have to replace it.

Answer:No monitors are being recognised. I can't see anything...not even BIOS.

it is plugged in to sata 2 with no jumpers, if plugged into sata 1 the computer does not boot past the first screen with the maxdata logo

Answer:SATA HDD not recognised in BIOS

Is the current boot drive ide or sata?
If you are in Windows, you need to go "Run,diskmgmt.msc, OK and see if it shows there. It probably will so you need to partition and format it there.

Also installed Norton Internet Security and checked Creative sound card drivers.

Answer:HDD Not Recognised in Bios and During Windows Set

As you have updated your BIOS I suspect it has reset to "Defaults".You will have to enter your BIOS at boot up, and change the setting from IDE to Sata, I think this is under the "Advanced" section of the BIOS, not forgetting to F10 out to save the changes.

Hello all,

I have bought a Samsung SP1604N. I am not sure if it is an IDE or a SATA (I suspect IDE)
1) How can I find which it is please?

I have currently got a Maxtor 6L200P0 200GB hard drive connected as my master which is working fine.

I have connected it the Samsung HD on the same ribbon as the Master and set it as a slave, master,cable select. None of them work. It is not recognized in the BIOS at all. I have tried connecting other smaller hard drives and then are auto detected fine.

I also have 2 DVD drives connected on another ribbon, I have unplugged one of those and tried it on that ribbon but still no joy.

My boot order is DVD, Hard drive then floppy. 2) Does this matter?

I have an AMD Athlon 64bit Dual Core 3800,
My mother board is an ASUS A8N-E

Any help at all is appreciated


Answer:Samsung HD not recognised in BIOS!?

Top is SATA, bottom is IDE

If you had to connect it to a ribbon cable, then its IDE.

If it's hooked up right (cable is in tight, and power cable is firmly attached), then I'd say the drive is DOA if your other drives work fine.

I've got XP home and have been trying to install GoBack v4. I tried a while ago, but Symantec said it wouldn't protect drives over40GB. I've got one of 30GB & one of 80GBI've now got the larger one partitioned, using Partition Magic 8, but GoBack seems only to be working on the C drive of 30GB. The Read Me file on the GB CD says this:Norton GoBack protects all disk drives that are recognized by the basic nput/output system (BIOS). If the disk drive is not recognized during the initialBIOS identification phase of the boot process, or if it requires special device drivers, Norton GoBack will not be enabled for that drive. I'm a bit wary of poking around in the bios - can someone tell me where I can find the section which presumably lists the various drives? The D drive is partitioned as D and L, as I've got various card readers, CD, DVD drives and a zip drive.Or have I messed up the whole thing??

I've had an SSD drive now as main drive for past 12 months and it has been really good, fast start up instant access you name it brilliant.
Apart from yesterday when it went missing, sounds daft but it just went missing from the PC.
It seems that it is getting to be a common issue with SSD drives and they do not show up in BIOS at all.
If this does happen to you there is a work -around that brings the SSD drive back on, posting link to one site that explains how to do it enter link description here it seems that this will work in 90% of cases.
It did work with my drive and it is back up and running so I thought I would post a solution here.
It's the first time that I have had a hard drive that doesn't even show up in BIOS .
Any way with luck nobody will need this advice but with SSD drives becoming more affordable you never know.

Hello. I've tried lots of other forums, but nobody so far has been able to help me. You're my only hope.

My BIOS won't recognise my new internal DVDRW drive (This one). Windows XP recognizes it, and it works perfecty.

The CDRW/DVD drive that came with my laptop 3 years ago (This one) has always been unreliable (cyclic redundancy errors galore). I got around this by using external drives, but my BIOS doesn't support booting or reloading via USB and - according to the guy at Time Computers (who I bought the computer from) - it cannot be upgraded.

Rebooting or reloading from the cyclic redundo-drive is nail-biting stuff. And this is why I bought the new drive.

So is there any way to get my drive recognised by the BIOS? I upgraded the drive's firmware, but that didn't help. And the drive isn't faulty - the one I've got now is a replacement of an identical drive whch I sent back because I thought that its BIOS-invisibility was due to a fault.

The guy at Time Computers said that my computer would probably only work with the original drive (due to some special ID number embedded in the drive or something), and offered to sell me a replacement of it for "£40-80". Pfft, thanks a lot Time Computers!

If that's the case, there's not much you can do except bend over and pay the 80 quid.

Surely that would apply to the other hardware as well?
Which means that your whole computer is a time bomb waiting to go off (pun intended).

Don't know anything at all about Time PCs i'm happy to say.
You could spend some time hunting down similar disgruntled users on the Internet and seeing if you can get to the bottom of it.

I have just bought a WD 1200JD Sata HDD. Installed it and enabled jumpers for SATA on MOBO. So far BIOS does not recognise the disc (I have searched) and if I go to the RAID SETUP on boot up the drive appears. When windows XP Pro starts it wants to install RAID controller. However it can't automatically find this.

Not sure what I need to do.

I currently have a IDE ATA WD1200JB HDD installed as master too.

Should BIOS recognise the drive? It does'nt so do I need a update? My MOBO is Asus A7N8X-E DELUXE. Surely not as my MOBO comes with SATA capabilities.

Do I need to use RAID with SATA? This is only optional right?

How can I get windows XP Pro to recognise it? Was thinking maybe need new service Pack, but I'd rather not! Could anyone explain what the RAID CONTROLLER is?

Hope this is clear guys.

> I have an A60 which started to switch itself off and then fail to boot.
I tried using the recovery CD which reinstalled the OS but the laptop still failed to boot after that.
For me it sounds more like a overheating issue caused by high internal temperature.
This is a typical issue if the cooling ventilators are clogged and if the air cannot circulate correctly.

I just bought a WD SATA 320 gb HDD and am trying to install it as an extra storage space - not a boot disk. the problem is that my mobo (ASUS K8V SE Deluxe) has two raid controllers. One is a VIA that i have two HDD's plugged in and not set up as raid - the boot disk (maxtor) is attatched to the primary and the other (storage) is connected to the secondary, and everything works fine. the second Raid controller is the promise 378 fAST TRACK controller and this is the one that i am trying to attatch the new 320gb HDD. I have updated VIA drivers, mobo bios, fastrack driver (fine in system). But Windows does not trecognise the drive.

If i put the promise controller as an 'ide connected device' in bios i can set the boot order and use my normal drive (VIA primary contoller - maxtor) which works fine but windows doesn't recognise the new WD drive plugged into the promise controller. But if i set the promise controller to 'RAID' in the bios and use the little prog to arrange the array, so it is recognised, the boot order changes and i cant access windows!! The bios recognises that there is a drive attatched to the promise fastrack controller and attempts to boot from that - but when i go into bios and attempt to change it back to the maxtor (VIA controller) there is no option to boot from the VIA Raid Controller - only the promise.

This is doing my head in! Has anyone any ideas as to why this is happening or an... Read more

Answer:RAID and ASUS HDD not recognised in Win XP, but is on bios. please help

Boot up windows and go to Control Panel -> Administrative Tools -> Computer Management and find the Disk management tab on the lower left. Click it and the HDD should be there. The reason it hasn't been recognised by windows is that it hasn't been formatted. Use this tab to format the drive (might take awhile).

Hey,I can't tell if it is a driver problem but maybe you can point me in the right direction.I have a Fujitsu Lifebook s6231 Laptop and a few months ago the computer would take 20 minutes to boot. The DVD drive has a quick-release and one day I found that the computer would boot fine if the DVD drive was disconnected from the computer. I figured replace the drive and all will be well.My old drive was a UJ-830B (a slim drive) and I tried replacing it with a UJ-831B. When it came in the mail the drives looked identical, just move the harness and install!The drive installed perfectly! sooooo easy, the driver loaded right from the drive and everything. I was playing dvds within minutes! but........The next time I turned the computer on the drive didn't show in "My Computer" or even the device manager. I did a lot of reading and found that it wouldn't be compatible if it wasn't recognized in the bios so I checked that. No cd rom in the bios!!!!It worked though, so I was confused. Remembering my old problem I started the computer without the drive connected. Then after Windows completely loaded I connected the DVD rom again. IT WAS THERE!Confused, I called the company who sold me the drive, he had never heard of my problem. He asked what the drive firmware was, it is 1.00 and so he asked me to send it back and he would replace it with one that had newer firmware. I didSame problem with now the UJ-840.

Answer:DVD drive recognised by Windows XP, not BIOS

I would suggest backing up all of your documents and files, then reload the OS fresh.Then try the new drive, it won't solve the bios issue, but it may allow it to boot with the drive connected.The problem actually sounds like bios, have you tried updating the bios?

I've just added a AMD Athlon XP 2000+ (1667mhz) to an ABIT NF7-S2 motherboard. When I boot up the BIOS shows it at 1050mhz with an FSB of 100mhz. If I change it to 133 or 166 the system either hangs or fails to boot up at all. I've updated the BIOS but it still won't give me the option to manually change the speed of the processor. Should I just accept that it will only run at 1050mhz or is there something else I need to consider?

Hello everyone. I have recently got a new ThinkPad L540. Since I need to use Windows 7 (TrueCrypted company Installation on normal SSD) and Ubuntu I bought a HDD Caddy for the UltraBay together with a 1TB HDD. My problem is, that I can not select the second HDD (HDD1) in the BIOS to boot from. It does not show the name of the drive, just HDD1. HDD0 has a name that indicates that it is the Intel SSD. The new drive is visible and usable in Windows and when I use a USB-Drive to install Linux on that second Drive.Furthermore I switched the SSD and the HDD and the L540 boots sraight up into Ubuntu. When I switch back its boots Windows 7 again. During the Ubuntu installation I tried both, writing the GRUB2 bootloader to the root-partition or to the beginning of the HDD (schould be the same since the root-partition is the first on the drive). Gparted is also thelling me that the root-partition is bootable. I hope somebody has an idea!Thank you very much for your help in advance!!! 

Answer:L540 HDD in Ultrabay not recognised in BIOS

Hi, I do a bit here and there with computers and as such a friend who has gone travelling left me his laptop that wouldnt boot to see what i could do.

Its a HP Compaq Presario CQ60
S/N: 2CE910CBC1
Drive: Samsung HM251JI (250GB)

I have run a number of basic tests on the drive with the following results;

1)Tried connection of the SATA drive through adapter via USB on my system and rebooted the system.

HDD was not recognised in the disk managment console within windows 7. Was not recognised in My Computer.
Disk did show signs of life and was 'Ticking' and sounded like a CD struggling to find a track.
I also, after several minutes got a pop up saying i needed to format drive k to continue (obviously i didnt formt).

2) Connected the HDD directly to the MB and PSU on my system as a secondary drive.

RESULT: The same sounds came from the drive as before; during and after a very lengthy boot up.
Checked the bios for the drive and it was not listed.

My friend only requires his iTunes and photos off the drive. Please would you be able to give me any pointers.
Many thanks

two computers were running perfectly, 1 athlon 1800 and 1 pentium 2 - both windows ME. After upgrading son's computer, attempted to install his old hard drive (IBM deskstar 40 gb) in athlon system as 2nd hard drive. All jumper settings were correctly reset. Computer would not boot into windows from c drive and bios reported as "no fixed disk present". Did also not recognise the transferred IBM drive as secondary. ME boot floppy used and possibility of virus mentioned.I then tried (foolishly) to install the IBM disk in the old Pentium as secondary, with the same results. I now have two computers where the C drive is reported as " no fixed disk present.If the old drive had a virus, is it possible that it infected the C drives before windows was started? Can the motherboards now be infected? Would it be safe to try to replace the C drives with a clean drive, or will this too be affected? Finally, as I cannot get into windows to run anti-virus program, does anyone no of an anti virus program that can be run from DOS prompt? Or any other advice to resue these machines, please.

Hi hope someone can help. I have a Toshiba Equium EA60-173 and the hard drive is not being recognised in the BIOS. When I take the hard drive out and put it in another laptop it is detected fine. I have also tried another hard drive in the Toshiba and that doesnt work either. Therefore I suspect the IDE controller has gone, but is there anything I can do to confirm this? I wish there was some option in the BIOS to force a detect. I have successfully updated the BIOS but still the same.

This laptop is only just out of warranty so if it is the controller would I need to replace the motherboard? Are there any other options available to me?

Thanks in advance.

Answer:Hard Drive not being recognised in BIOS - Equium A60

Hi Neil,

Unless there is some physical\problem with the Hdd connector/cable then it is quite likely that you will need a new mainboard for your notebook. I suggest you contact an authorised Servic Partner and ask them to check your notebook and give you an estimate of the costs of the repair. Then you can try to shop around for any cheaper alternatives.

A couple of months ago the system drive on one of my old PCs suddenly stopped working - not particularly surprising given that it's about 10 years old. I swapped it out and left it until I had time to try to pull the data off it. It's a 60GB Western Digital Caviar WD600AB-32CDB0 EIDE drive. Now, when I connect it to the secondary IDE bus on my PC it does seem to spin up and the BIOS recognises it no problem, but neither Windows XP (Disk Manager) nor Slackware Linux 9.1 (cfdisk) do. This is not a situation I've come across before (disk recognised by BIOS but not the O.S.). Does anybody know what the problem might be and what I can do to try to resolve it? I have been pretty careful with its usage over the years (eg. not having a paging file) which I guess is why it has lasted so long, but I don't really need to use it any more - I would just like to pull the data off it if possible without incurring significant expense.

Edit: I forgot to say, on bootup SMART reports no problems!

Thanks very much,


Answer:IDE Drive Recognised by BIOS not by Operating Systems

Hey 3g. I've never been in that situation myself, I do believe the BIOS only reads parameters about the drive that it gets from the preprogrammed circuits in the drive, whereas Windows is trying to actually read data off the drive and can't. Is the drive configured correctly for where it's placed with it's jumper pins?. You may want to run a diagnostic test on the drive from the link below

the drives are good units as they work with a USB caddy on another machine..

I need the optical drive to work so that I can re-install, as the hard disk has now become corrupted. The recovery seems to require the laptop to boot from the CD drive.

If there any suggestions on how I can install onto a formatted hardrive, without using a usb cd drive, that would be cool..

Answer:Equium A210 - Known good cd/dvd drive not recognised by BIOS

> the drives are good units as they work with a USB caddy on another machine?

The BIOS does not recognize the CD/DVD drive because of wrong master/slave/c-sel settings. You have to use a compatible CD/DVD drive. Such CD/DVD drive can be ordered from local ASP.

> Are there any suggestions on how I can install onto a formatted hardrive, without using a usb cd drive, that would be cool..

Maybe you could be able to install Windows from USB stick?
I?m not sure if the BIOS will support the booting from USB stick, but it?s worth a try.

Satellite L100 - 170 Model No.PSLA3E 02501QEN running Win XP.

The CD/DVD drive icon has disappeared from My Computer and is not listed in Device Manager or showing in the BIOS.
There is power to the drive and the tray ejects OK
I have tried using the Add New Hardware facility in Control Panel but it does not list a CD Drive.
I have removed the drive and then re-seated it but it made no difference.

I have used System Restore to the last available date 26th January 08 but it does not restore the CD drive...and I no it was working at that time.
I don't think this is a faulty drive as it is picking up power and when you insert a CD it starts up as though it were about to read the disk but nothing appears on screen.

Answer:Satellite L100: CD/DVD Drive is not recognised in Bios or My Computer

Well, usually if the CD/DVD drive doesn?t appear in the BIOS or the BIOS cannot recognize the ODD then the chances are that the CD/DVD drive would malfunctions.

But the best way to check this is a new OS installation. You should try to boot from a bootable XP CD.
If the notebook would be able to boot from the CD then the hardware is ok.

After that i have Satellite m110 :(

Answer:Tecra A7 after Bios update is recognised as Satellite M110


Sorry but I don?t understand you procedure!
Did you read the BIOS update document provided by Toshiba?
The BIOS update is risky if you use a wrong BIOS or wrong update procedure!

I have checked the Toshiba driver site and downloaded the BIOS for Tecra A7.
I have unzipped the bios-510win and I found the file S10V510.exe
This is one file. You have to run it!

For me it seems you used wrong BIOS or the wrong procedure and therefore the notebook shows a wrong name.

PS: Don't worry ;) the Satellite M110 is also a great notebook :D ........ just a joke

Hi there. I have a desktop where startup takes around 1minute (during that time HP logo showing) and then freezes during the 'Microsoft Windows' logo (with the bar below not moving). Had to do a hard reboot (press the power button for 10secs), and just keep re-booting until it would finally boot properly. Although I did found out why my PC hangs -- and it's because BIOS doesn't recognise the DVD-drive, which causes windows to freeze. But once I reboot it, and it does detect the dvd-drive, then my PC works beautifully with no problems.

My question now would be: Why can't my PC detect the dvd-drive on BIOS the first time it boots? If I restart my PC, then it's also OK. It's only when I do a shutdown and then boot my PC that BIOS can't detect the dvd-drive. So most of the time I just end up not turning off my PC just to avoid the problem of booting my PC. But it would be good if I can turn off my PC (and save electricty) and not slowly killing it by doing hard-boots all the time.

My PC specs are:
HP Pavillion Slim s3380a
Windows Vista SP1
2Gb memory

I've seen other forums where they recommend removing upper/lower filters and I've done that too but didn't make any difference.

Any other suggestion will be greatly appreciated.

Dear all, I'm going through a disastrous situation with my Lenovo ThinkPad 15 (0301-CTO) laptop.  I am running Windows 7, which was factory-installed.  Following an automatic windows 7 update (around 30-40 updates at once) on 14th September, the computer restarted itself automatically.  The first issue I noticed was that the wireless adapter was not working.  I was able to fix this by switching the adapter on and off. The second issue was that my USB mouse had stopped working.  I later realised that this was actually because all my USB ports had stopped working, so flash drives, external hard drives, etc. we're not recognised. The first steps taken to try and sort this out were:Uninstalling all the new updates.  I foolishly hadn't enabled system restore, so that wasn't an option.  Removing the updates had no effect.Running thorough scans for viruses and malware, using Avast and Malware Bytes.  Noting was found.I used Windows Device Manager to check the USB drivers - apparently they were all up to date.  I uninstalled and reinstalled them all anyway, but this made no difference.After trying these things and restarting my computer, the problem got worse:  I could no longer use the Internet as no network adapter could be found (wireless or LAN), I couldn't use my DVD drive, no bluetooth adapter was recognised, microphone and camera have all diappeared.  I tried restoring to the point before I reinstalled the u...

Hi Geeks,

My Secondary hard drive has just disappeared and is not available in the BIOS or in Disk management.
This occurred immediately after installing Android SDK (on the drive in question)
An error message popped up in the tooltray with a write delay notification, I ignored it (regretfully) and proceeded with the last step of the SDK which was ADB restart (or something similar) which had failed.
After this, the drive had disappeared from my computer and it's nowhere to be seen.

The drive in question is a 750 GB SATA.

If anyone can help me with this I'll buy you a coffee.

Answer:Soundcard recognised. Crash. Soundcard not recognised. Wait 2Hr Recognised Again ??.


You didnít mention if your sound card is built into the motherboard or is an add-on card. I'll assume itís an add-on. I would check to make sure the sound card is seated firmly in the slot, or another option would be to try another slot. Perhaps the one you have the sound card in is bad. Also, you may want to uninstall the driver for the sound card and download a new one from the manufactureís website.

You also mention that your mouse pointer jumps all over the screen. Usually when this happens to me, it means the battery's are starting to run out and need replaced. Also, try moving the receiver as far away from the monitor, speakers and tower. Interference from any of these devices can play havoc with the signal.

Good Luck.

just to rule it out, you may wish to pull the palmrest and check the fpr connector to assure it is securely attached. if you don't have it already, te hardware maintenance manual should help with the process:
if that doesn't help, and since your machine is so new, i would recommend contacting Service to discuss your options.

Hi all Last year I used the Lenovo system update software and it did a BIOS update following which the battery is not recognised so if I pull out mains power it hibernates.  I'm sure it's a BIOS issue but if I try to upgrade the BIOS it stops me halfway through as I don't have a full battery ie what comes first.....!. The problem is definitely not the battery age as I bought the computer off my work and the batteries had been replaced a few months before I did, and it hasn't been used that much. I'm not sure it's a IBM/Lenovo battery- it's not clear as it has a sticker on referencing model number VIS-50-T40L.  Would be a bit crazy if you can't use  non IBM/Lenovo batteries  I tried to fix it but gave up, and used my work laptop, but have just found these new discussion boards so will try again. If I had a dollar for the hours I've tried to fix this I'd be richer than Bill Gates - quite disappointed with Lenovo that an auto update  could do so much harm. It's the most rididculous problem that has driven me bananas for 12 months so if someone has the answer then I'll be eternally grateful. CheersMessage Edited by camtastic on 06-07-2009 09:22 PM

Hi guys, I want to connect my ps3 hard drive on pc to use it on pc, so when I get my new computer I can use it with it straight away, but right now I want to use it on my current pc, I plugged in both the one cable and the other one (sata), that goes from power supply cable to the HDD.

when I booted the pc it said installing device drive software, and said, device is ready to use, I go to my computer, and it ain't there, do I have to set it as secondary in bios?

Win7 Ultimate final rev

It's automatically set as fourth IDE master. restarted pc and still doesn't show up, I heard I need to format, is that true? like that to know if I should re-gain windows 7 disk

Oh and t's actually 320gb

Answer:250gb hdd ps3 on pc?

Open up Disk Management (in the admin tools control panel), it should show up in there. I'd delete all the partitions and create 1 new one that incorporates the whole disk. Then format as NTFS.

Answer:250GB Hdd Not Recognized


What do you mean the laptop won't recognize the 250GB drive? Do you mean in the BIOS? When trying to install Windows? You can try to download a linux LiveCD like Knoppix or Damn Samll Linux and boot from that (F9 or F12 at the Dell BIOS) and see if it sees it. If so, format with QTParted or Fdisk and then try Windows again. Maybe the drive is bad.

Let me know if this helps.

Question: 250gb hd problem

Hitachi 250gb hd, was working fine, everything was ok. It was split into two partitions a 128Gb clip, and a 104 gb clip. The 128gb clip had information on it. Now the drive is recognized in bios properly. When it boots to windows it comes up as 8gb, and has information on it, but I can't access it. One more thing the drive now says fat, when originialy it was ntfs. Under manager, The drive says it is split at 138g and 104 gb. Any ideas? when I run a drive test the drive says it has a bad cable, I swapped the cable out three or four times, to no avail.

I think I have it all listed, oh windows xp home, installed on it's own drive.

Answer:250gb hd problem

Has nothing to do with drivers or Spyware, it is more of a Bios issue. What is the manufacturer and model of the computer that this drive is in? Also, do you have SP2 installed for XP?

I just bought a maxtor DiamondMax10 250GB HDD...
and i bought an external case so i can use it on my laptop(toshiba A-50)..

I have used a 400GB external Drive on the same laptop before..
I have also used 200GB external drive before on the same laptop..
all of my previous hdd were western digital....

The problem is:
I wanted to format (partition) the hdd... but the computer said that the capacity (unformatted) is around 2 TB
i tried to format it as one partition, it wont do it...
I tried to minimize the capacity to an acceptable (close to real) level (set it to 230Gb) but it wont do it...

I tried to format it using FAT32, and it worked but to a maximum of 200Gb, it is ok... but the problem is that i can only use 10 GB after that the harddrive gives an error (write-protected)...

1- have anyone used Maxtor drives before as externals???
2- Have any one came across this problem before ???
3- Will it work in a normal PC or not?? (just to format it)... because getting a pc in here is quite difficult

Thanks in advance....

I'm sure this is simple, but I can't figure it out and searching google hasn't found me any answers. I am building a new system. It all works fine. But I have a WD 250GB hard drive I"m using. When I boot from WinXP Pro CD, and go to format the drive and install the OS, it only tells me I can format 130GB of space. Nowhere to be found is the rest of my drive...

Any thoughts as to what I"m doing wrong here?


Answer:XP won't format whole 250GB HD

Hi, if the version of Windows on the install CD pre-dates Service Pack 2, you will get this problem.

Microsoft added the ability for Windows to see hard drives bigger than 137 GB in Service Pack 1 (and Service Pack 2).

If you have access to another PC, download Service Pack 2 (which includes Service Pack 1 btw), and integrate it into your install source and burn a new CD from which you can install. You can find good instructions for doing that here:

You can download Service Pack 2 (full 266 MB package) from here:

As a workaround, you can create a partition less than 137 GB, install Windows, and then install Service Pack 2 and you will be able to access the rest of the hard drive. Then you can partition the rest from the Computer Management interface (right-click "My Computer" > Manage...)

Hello, I'm hoping I can find a solution to my problem here as I couldn't find one elsewhere on the net.
I have a laptop and currently have a 120GB hard drive in an external enclosure. I have just bought a new 250GB hard drive and have installed it in the external enclosure. Though partitioning and formating the 120GB was a breeze, I've had nothing but problems with the new 250GB.
Below are the specs of what I'm working with. In both Partion Magic and in the Win2000 Disk Management, it correctly displays the 250GB drive (233GB). Regardless of which program I use (ie. Partion Magic, Win Disk Management, command line FORMAT) I get problems.
Generally, what will happen is it will partition fine. Then it will begin to the formatting process (VERY slowly) and then either throw an error either during or at the end of the process. And this is when I try to format a very small partition (ie. 100MB). I have successfully formated a 10MB partition. On a large partition (ie. 30GB) the format process will start but will not progress.
The only two things I can think of is that the drive is faulty, or because I am booting my OS from a floppy there is some sort of recognition problem.
I can't run the diagnosis software from Maxtor because that requires the drive to be installed internally.
So any help to this problem will be greatly appreciated.
Additionally, how long should it generally take to format the 250GB drive in its entirety?

It said Trap followed by 0000005c ==============EXCEPTION=========================== and a series of hexdecimal messages afterworsd. I've done this twice and had the same problem and I just wanted to know if you guys knew anything about this?

Answer:Installing Win XP Pro SP2 on two 250GB HDD

Greetings gfx dude, Welcome to TSF!

Firstly, you only need to install the Operating System one ONE of the HDD's not both of them.
The second HDD can be connected as a "Slave" and can be used to 'save' everything that you download, plus emails and other data, such as music etc.
I suggest that you check the CD for scratches and marks; wipe it very gently from the centre to the edges with a lint free cloth.
To give you the best chance of getting Windows? installed without hassles, such as those you are experiencing, is to completely wipe the HDD with Darik's Boot N Nuke.
Wiping the HDD this way will completely erase everything off the HDD and take it back to a RAW unformatted state, as if it had just come out of the factory.

Just so that you do not forget anything when doing the installation, please read this...

The Windows? XP Installation Check List.

1. The Windows? XP SP2-CD (naturally)

2. Darik's Boot N Nuke (Click the coloured Link).

3. Please read this guide.

4. The Motherboard CD that contains all the necessary Drivers etc.

A couple of tips...
a. Darik's Boot N Nuke will take about 4? hours to completely wipe the Drive; however, this will vary depending on how big the Drive is. (That estimate is for a 80Gb HDD).

b. When you get to Figure 7 in 'The Guide', you can create more than one partition here by simply telling Windows? how big you want it. Should you do decide to create an extra parti... Read more

The drive manufacturers reckon a kilo is 1000 (reasonable, I suppose), but the rest of the computer world regards it as 1024.So a 250Gb drive is 250/1.024/1.024/1.024 = 233Gb.

Question: Deskstar 250Gb Hdd

I just bought a new deskstar 250Gb Hdd which I am trying to install in my Compaq Pressario S3190UK

I know its got to be set to slave but I wasnt sure if I should set it up as a
16 head, a 15 head , 32 byte clip or auto spin dissable and all of those choises are available on the drive

I went for 16 heads and booted up

In " my computer " the new drive does not appear ( I still see all my original drives there) yet in System/Hardware /device manager it shows up under drives and on clicking its properties it says this device is working properly

Without seeing it in the " my computer folder " I cant really format or partition it so I then tried partition magic
That saw it fine and reported its size correctly . I told it to create an ntfs partition and use all the drive . It changed color as it should and all that was left was to click on make changes now but when I did that it went straight back to tell me the new drive had no partitions created

I tried various combinations, of primary or logical drive , small or large partitions and fat or ntfs but always it refuses the last step of actually creating the partition .
What am I doing wrong ?



Answer:Deskstar 250Gb Hdd

First I will assume your drive is showing up as the full size in the bios and is corrrectly identified.

If you are using either xp or win2k. Go to disk management; start>run type in diskmgmt.msc and hit enter. See if your drive shows up there; it should be listed as disk1, disk0 will be the master drive. If it shows up there, you need to partition and format the drive. Right click on the drive and choose to create a partition; I like extended partitions for data / storage drives. After you create the partition, right click again and choose to create logical drive. You can make the entire drive one partition or organize it into say 3 logical drives; whatever you want. After you create the logical drive you will need to format them. Again right click on the logical drive and choose format. Use ntfs for your drive. In fact if you use partitions greater than 32 gig, fat32 is not even an option.

Just think about how you want it organized before you start.

Answer:Samsung SSD 840 EVO 250gb

Benchmarks are artificial at best [and a benchmark from the mfg is tailored to that particular piece of hardware] I would think you would get different results using a another benchmark program such as ATTO.

In short do not put too much emphasis on any given benchmark. Modern ssd drives are reliable and it should last for quite a while so I would not worry about the drive.

I was going to partition 30GB to linux and keep 30 for Windows. Then transfer my OS to the remaining 30GB, that would free some room. I am a gamer so I need alot of room for games. If I get the 250GB HDD then I would have alot of room for more games and linux. But then I would not be able to boot Windows 7 in seconds. What should I get?

Answer:SSD 60GB or HDD 250GB?

Go with an SSD. If you choose the 60GB SSD, you will have just enough space for the OS and a Office Suite and a few other apps before you start to run out of space. If you can afford it, go with a minimum of 128GB SSD as your primary drive, then wipe your 500GB mechanical drive and use as a storage drive.

Hi Rxgamer,
Welcome to Lenovo Community!
I understand your concern, but let me inform you these partitions contain recovery image and Drivers/Default Applications. By deleting the OEM (Original Equipment Manufacturer) partition the system will loose its ability to "Factory Reset/ OKR (One Key Recovery)" of the system.

I am new to this forum and desperate to find a solution to my problem. My colleague told me of this service and here I am.I had a Windows98 PC with an external Maxtor 250GB firewire connected to it. I took the main HD out (the one with the w98) and installed new one and installed a newly purchased copy of XP. At this point I've connected my Maxtor without installing the driver thinking that XP would recognise it, but nothing happened. I installed the driver but nothing? it can be seen in the disk management as disk 1 and that's all; the next step would be a format, which I refuse to do it.I reinstalled my old drive (w98) back into the case, win98 started as normal, I connected the Maxtor and to my big surprise this drive is not being recognised anymore; even when the PC configuration is exactly what it used to be. I only can see the Maxtor through fdisk but not anymore as a 250GB FAT32, apparently now is a 40GB FAT !?!?!!.Please help me. I have far too much data on this drive including pictures going back 4 years and documents. This drive is a back up of my previous PCs. I cannot afford to lose this data.ThanksAndy
