Windows will not recognize 300gb hard drive?

Question: Windows will not recognize 300gb hard drive?

I just reformatted windows and all i did was delete the c drive partition, and then install xp on that partition. This was all on a 80 gb hard drive that was formatted into 30gb and 50gb. windows is on the 50gb partition and it works now. But I had a 300gb hard drive before i reformatted which was just for storage, when i reformatted my computer i did not even touch the 300gb drive. But now if i go into xp it will show up as a raw drive as in not formatted. And the 300gb hard drive only shows up as 127gb. But it should show up as two 150gb partitions. If anyone wants me to clarify anything please ask. I really need this data back since its all my pictures and i have homework on there.

Preferred Solution: Windows will not recognize 300gb hard drive?

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.)

Answer: Windows will not recognize 300gb hard drive?

my friend had the same problem but he just formatted it and it was fine.... hook it up in another computer, maybe the only way to get your data back..

is it sata??? might have to install the drivers for it.

I have a 1 TB drive that's been partitioned into two separate drives of 465GB each. One has Windows 8.1 (I use to work from home) and the other is Windows 10 for personal use and my preferred operating system.
However, the drive with 10 installed on it has a whopping 300GB of used space and I can't figure out where it's coming from. I've cleaned out all unnecessary files with the cleanmgr but that was a blip.
I also deleted all of the restore points, which is set to use 10% of the drive's capacity.
My documents, download, video, music and photo folders are a combined 13GB and I figure the Windows 10 installation is taking up maybe another 20GB for a combined 33GB out of 465GB.
So what exactly is the rest of the 267GB comprised of and where is it? The load times are way slower than they should be and this is just something I can't wrap my head around.
Any suggestions?

Hi.  I have an older Dell laptop running on XP.  Can I install a 300 GB SATA drive on this unit and expect everything to run okay?
Also, is there any concern about moving away from XP and to, say, Windows Seven?  My friend says XP will become a problem when MS stops supporting it next year.  I would just as soon stay with XP.

Answer:Can I Run a 300gb Hard Drive on an XP laptop?

Please post the model of this Dell.
XP has been one of Microsoft's better operating systems.  When Vista came out it had lots of problems, so they trotted out Windows 7 which has proven to be every bit as good as XP was.  You can use Microsoft's Windows 7 Upgrade Advisor to determine if your laptop will be compatible.

According to the specifications of the Y550 (418644U), my hdd capacity supposed to be 320GB. When I go to Disk Management in Windows, it says : Total : 298.09GBPartition C : 252.95GB, Partition D (Lenovo backup) : 30.38GBEisa Configuration  : 14.75GB So...When they say 320GB, do they refer to the Partition C? ...which would be weird. But even if they don't refer to the partion C, I still don't get the full 320GB. Do you think it is a mistake? I am also not very satisfied so far. I have a hot pixel (red all the time) and a dark keyboard which was not expected at all.

Answer:Y550, Hard drive of 300Gb???

If you look at any other computer, you'll notice that the actual amount of space available is less than advertised. That's because 1MB is not 1,000KB, but 1,024KB. However, when advertising, companies will use 1,000KB. This applies to all ranges of memory (i.e. 1GB is 1024MB and not 1000MB). So you actually end up with less HDD space than they say. If you don't quite get it, here's an illustration. Let's say that you buy a 2MB HDD. The company will use 1,000KB to define 1MB, so you have 2,000KB of space.However, the computer defines 1MB as 1024KB. Thus, 2,000/1024 = 1.953MB.As you can see, you have less space than what you are told.

I didn't know whether to put this in the "Performance & Maintenance" thread or here.. but here it goes.

I have a quick question about partitioning. I have a ~320GB 5400RPM hard drive and I would like to partition it. I'm re-installing my OS so I will be starting fresh with formatted hard drive.

Here's some info about my usage:
I'm using a Dell Inspiron 1545 laptop (I think my specs are on my profile?)
Right now, my hard drive is at 240/300GB used.
I use iTunes RELIGIOUSLY, my library has at least 4,000 songs and I have apps, so in total my iTunes folder in the Music folder is about ~65GB. I have my iTunes set to where it makes a copy of whatever song I drag into the library and organizes it. Therefore, I delete the original downloaded music file to save space.
I browse the internet Google Chrome 24/7 and stream videos.
I use Office programs a lot, I have lots of documents due to school work.
I also use programs like MATLAB and ChemDraw (3-D molecule simulation) programs for school, as well.
Sometimes I use Photoshop to some of my pictures I take on the go.
I play FIFA 12 and other 3-D games from time to time.. I don't want it to lag, though.
These are large file games.

Also, I heard a lot about Linux Ubuntu, so I would like a partition separate for that dual-boot.
I would also like a small partition separate for "Recovery."

What do you guys recommend on the size/number of partitions?
The only reason I'm doing this is because I've read on several ot... Read more

Answer:Partition recommendations for my ~300GB hard drive?

Welcome to the forums!

Its mainly up to you in the long run. Personally I'd have at least three. One around 100gb for the O.S. (you'll have a 100mb system reserved automatically from Windows) and programs/utilities. One about the same for your school work and another about the same for your music and videos. I would highly suggest and recommend getting an external for back-up and recovery purposes. That would also leave you the extra space on your internal. 320GB goes pretty quick! Its all up to you in the long run and what you feel comfortable with and need. Again I would seriously consider getting an external for back up purposes, I promise you won't regret it.

Hello, I have a 931GB hard drive and up until a couple days ago it was sitting at like 300gb used out of the 931, today I randomly look at it and it says I have 50gb of free space left and the whole bar thing is red under my computer. I googled the problem and people said it was probably too many restore points so I limited it to 4gb, with no decrease in hd space, then I did a system restore to a date when my hd was fine and still no change. I've also ran virus/malware scan with nothing detected. Anyone know what I can/should do?

I recently bought a new Motherboard and CPU, and decided to move up from XP to Vista Ultiamte (64bit) I put the disk in and booted from it, and the setup could not see my HDD. I put the XP setup disk in, and this could see the HDD fine, so i formatted it using the XP disk. I then put the Vista disk back in and it did see my HDD, but only 34.6gb of it when there is actually 300gb. It is an IDE Hard Disk. What have I done wrong?!

Thanks in anticipation


Answer:Vista only sees 34gb of my 300gb hard drive

How did you set the jumpers in the back of the drive? There was a time when drives had a jumper to limit to size to 32GB (because otherwise the motherboard/BIOS wouldn't recognize the drive and it would hang). Basically the jumper setting makes the drive act as though it were a 32GB drive. I don't think they use such jumpers for drives that large (300GB? I think that's long after the 32GB limit problems were fixed).
Anyway look in the manual that came with the drive, or on the stickers, or even the manufacturer's web site for jumper settings. It might be named CLJ (cylinder limitation jumper), 32GB clip (on some hitachi drives), or even cap limit (maxtor).

just to clarify, you don't want it set to CLJ (just pick one of the other settings: master, slave, cable select, single drive - whichever is appropriate for how you connected the drive).
and I just looked on the back of my hitachi 500GB, there is a jumper setting for 32GB clip, so that setting isn't quite dead yet!

Im currently looking at buying the Maxtor Diamondmax 10 300GB (SATA) 7B300S0 hard drive but wondering whether its worth buying two, say, 160GB HD's instead. Im going to be using the PC mainly for gaming (im building it from scratch, first time so bit nervous but hopin itll be fine ) and the parts im currently considering are:
Asus A8N-SLI Deluxe Motherboard (supporting AMD 64 CPU's)
AMD Athlon 64 3800+
Crucial 184-pin DIMM RAM 2GB kit (Part number: CT2KIT12864Z4OB)
XFX Geforce 6800 256MB PCI-Express Graphcis card
Microsoft Windows XP Professional x64 Edition OS
A-top X-Blade Ultimate Black case with 580 Watt PSU

The main factors are speed and I dont want it to cost too much, the one im looking at is 160 so I guess up to 200 is acceptable. Id also like it to be at least 300GB as I want surplus space to ensure I never run out . Finally if anyones got any advice on the set up im planning to use please paste it in the 'First time PC builder' post in the cooling and modding section. Thanks.

Answer:Which is best, one 300GB hard drive or multiple smaller drives?

Ok. If you want redundancy go with the two 160 GB. If you plan on just backing up all of your data via tape or DVD, then the 300 GB is ok. I always like to have more than one drive anyway. I guess it is kind of like a security blanket.

I recently changed pc's, and I took the guts from my old PC and plugged em in to the new one.

everything has worked out fine, the RAM and the video card..


my kind of old (3/4 years) maxtor 300GB ata 100 16 MB cache internal harddrive is acting up.

it processes the data on it extremely slowly.

i used to use it as my master harddrive but now im using it as a slave since (i think) the bios of the new computer isn't working with whatever data is installed on my maxtor.

but this makes perfect sense as it has data on it that made it work properly with my old pc's bios/motherboard

not this pc.

but what doesn't make sense is why it is so slow as a slave internal harddrive.

i mean the good news is that i can still access the data, but transferring even 1 gigabyte (my old programs, like games) takes about 13 minutes.

that's very strange, as i remember back then when i used it as my master drive, i could exchange info on and from it at a much higher speed. and my old slave drive that i don't use anymore used to go way faster than my maxtor as my slave drive now.

I checked for drivers but apparently there really aren't any drivers in the first place.

can someone tell me what's going on?

Answer:T60 hard drive replacement - Windows does not recognize the hard drive

It sounds like you're doing something wrong, if the drive is an SATA it should work, just install it and boot from your windows setup DVD and it will setup the drive and format it for you, or you can optionally setup the partitions manually when prompted to do so. If you're trying to do something unusual like transfer the windows from the old drive then you need to explain exactly what you've done because I see no reason this shouldn't work. Infact I've done it many times myself.

I'm currently using a MacBook Pro i7 and My OSX fails to recognize the NTFS partition which my Windows 7 Ultimate is installed on.
It seems something has gone wrong during the boot camp installation.

I've tried everything to solve the problem, but I never had luck.

The thing is, my Windows 7 drive is about 300GB and there are a lot of applications to be installed when I reformat it that would require more than the time it would take to copy a 300GB data at USB 2.0 speed rate. Not to mention the time it takes to re-configure all those applications.

What I've figured out after days of research is that in order to solve my problem I had to rebuild the partition table so that my Mac OSX would recognize my NTFS partition this time which is not possible without having my hard drive to format some of the drives.

Some of the application configuration is very easy to migrate, like ones that store their data in AppData folder, but I do also have numerous application that scatters their configuration files, project files and etc all over the place. One of the great examples are Adobe applications.

I do a clean install of Windows once to twice a year on every PC's and it is usually easy when I partition them, but the laptop already has four partitions so I did not have a chance to make an additional partition.

Here is my partition table just to give you clear picture of my hard drive on my laptop.

Answer:Back up my 300GB Windows 7 drive

It sounds like you should be able to use Windows 7's built-in system image tool. Go to Backup and Restore in Control Panel (type "backup" in the Start Menu) and click "Create a system image" in the left pane. It should then let you pick the drive to want to store the system image on. When you're done partitioning, you can then use the Windows 7 disc to restore the system image to the new partition.

Answer:Windows won't recognize my new hard drive

Have you formatted it? New HDD's come in RAW format, which is not recognized by Windows or any other OS. Go into Start > right click "My Computer" (or 'Computer' in Vista) > go to "Manage..." > click on 'Disk management' on the left-side pane > now find your 500GB drive on the right side pane when it loads > right click it and choose to format it/create a new partition. Make sure you do a full format since its a new drive.

I had a hard drive which I wanted to reformat. So I back it up and went did a "quick format" on it.

At that point my 4tb which showed 3.6tb reformated to 1.63tb.

When I go into disk management Windows which previously saw 3.6 of 4tb only sees 1.63tb.

So I started over from scratch.

I deleted the volume, initialized the disk to GPT and but still all it sees is 1.63.

I have two storage drives on this computer and my other storage drive is recognized as 5.45tb on a 6tb drive, so it's not an issue of Windows not being able to recognize the drives.

It's not that it's not formatted properly as it is initialized to GPT.

Out of curiosity I went into Linux with a live usb stick and used GParted. I was able to see the full allocation on the disk and I formatted it in Linux.

Upon exiting Linux and going back into Windows, NOW Windows shows me the full 3.6 capacity. However other partition managers like Easeus, or MiniToolPartion now report 122% capacity .

I figured I could just use it since Linux seem to get it formatted correctly, however since it will be used for storage I was a bit nervous and still don't understand why Windows which once allowed it to be formatted correctly won't let t.

I also checked the drive with the SMARTS tools by Western Digital and they found the drive fine and report 4.0 as the capacity for the drive.

I thought perhaps a driver issue, but it just then the other drive is fine and so was this one previously.

Answer:[SOLVED] Windows will not recognize my hard drive

Have you installed any of the windows updates since reinstalling?

What is the size of the drive that is not showing up?


Windows XP support for 48 bit LBA (needed for drives larger than 137GB) support is as easy as installing Service Pack 1 or 2. This enables support for drives larger than 137 Gigabyte.

I just completed building my own PC from scratch. I am trying to install Windows 7 Ultimate OS 64 bit. The Bios is recognizing my western digital Hard drive, but once Windows 7 tries to install it is not recognizing my Hard drive. It is asking me to install the driver for the hard drive. Is there some other setting I should be changing in the Bios to have the OS recognize my hard drive. What exactly is Raid and AHCI Sata Mode and should this be set to default. The Motherboard comes with a driver CD, but it says to install and OS 1st. Help ASAP would be much appreciated. Thanks.

Answer:Windows 7 Install won't recognize my hard drive.

One option Im sure some one will frown upon but it worked for me on my Lenovo T500 was to turn AHCI to Compatibility Mode and then try it. Otherwise you will need the raid/SATA drivers from your computer manufacturer on a flash drive to install Windows 7 (Press F6 during Setup start).

The internal HD i always use is SATA. I bought a raid controller for other purposes but it had an IDE slot on it so i decided to use the other spare HD i have (internal also).
I can boot off of it and see it in paragon and device manager,but it wont show up under hardware and devices,my computer etc.

Any way to fix that?

I have a Dell Demensions 4600. I attempted to install a Maxtor OneTouch 4 Plus external hard drive. Upon installation I received a "windows could not load installer for HDC" error message. Once setup was finished, the hard drive is not visible under "My Computer". It is present in disk manager, and says that it is "healthy". I tried reassigning the drive letter, which did not work.

In an attempt to make more space for my media files, I created a new partition on my computer and simply moved all of the files from my previous 40Gig partition into my new 100Gig partition.
Everything was done using the built-in software that came with Windows 7 Ultimate.

Things went fine for a while, then I wasn't able to load my PC.
Fair enough, I reinstalled the OS.
It worked for a few hours, I installed all the updates into my system after the fresh install.
But when I turned it on in the morning, it worked for about 30 minutes and then I got a blue screen and it auto-restarted.

Now, I can't access Windows or even reinstall it.

I have a Dell XPS 400 (XP media center) that I am fixing for someone. It gives the error message that HAL.DLL is not found. Usually I can fix these kind of problems without a hitch, however...

the windows Media Center installation CD does not recognize the hard drive. I can not run the recovery console or reinstall. I get a Blue screen stating that windows did not find any HDDs installed in my computer. I have a copy of UBCD4WIN that was made from an image of this same disk. Running UBCD4W I can access the disk, and ran HDTUNE which found no disk errors.

Any idea why this is happening? It is a SATA drive, and obviously the BIOS recognizes it.

Also, does anyone know of any utilities that may help me on the UBCD4win?

I recently installed windows 7 home premium 64 bit, previous OS was Vista home premium 32 bit. My desktop is an HP pavilion d4650y.

I have the OS loaded on my main HD which is a SATA.

HD & DVD drive worked perfectly before on vista. I tested both devices on another pc with XP and they work fine. I've triple checked the connections but still the devices are not recognized by win7. I've also tried renaming the HD & changing the drive letter, but still no luck.

Both drives are connected to a PCI E card, and are set to cable select, on separate cables.

In the BIOS both drives show up.

In disk management they do not show up at all.

My HD is a western digital 250 gb EIDE, and the DVD drive is a IDE Pioneer DVD burner (secondary disc drive).

I just purchased an HP Spectre x360 back in November - so it is pretty new! Suddenly this weekend, I began getting the BSOD. I've tried to reset my laptop and it won't allow me to reset. I've tried to restore to a system restore point and that still doesn't address the issue. Doing an "refresh" of Windows does not fix the issue. So I decided to ust nuke the whole thing and install a complete fresh version of Windows 10. I have a USP drive that is bootable with the installation ISO. I am able to boot to the USB drive just fine.  But when trying to do a clean install, my laptop will not recognize/find my internal hard drive, even though I'm able to boot to it just fine! The only drive it seess is trhe USB drive I'm using to boot from.If I do a "diskpart" when in Install dialog,  and list disk, it only shows the USB drive. No idea what's going on, but am literally at the end of my rope with this Spectre and Windows 10! I've never had more issues installing an OS in my life... If anyone has any insight/solution, it would be greatly appreciated!

Now windows install doesn't recognize the hard drive to install Windows XP on to.

I'm connecting a 30GB Travelstar Hard Drive via an external USB 2.0 case to my Thinkpad T40 with Windows XP (pro). Windows immediately recognized it. However, the hard drive does not show up under Windows Explorer. I can go into Device Manager, click on Disk Drives, and it does show the new drive there (along with my main hard drive, which is a 80 GB hard drive).

I cannot figure out how to make it show up in Windows Explorer with an Drive Letter assigned to it and thus, how to actually use it.

I have used the windows xp install cd to format the hard drive as both FAT32 and NTFS, but Windows XP still will not recognize the hard drive when I boot up.

I have also tried going into Computer Management/Disk Management ... but the hard drive does not show up under Disk Management.

However, it does show up under Device Manager under Disk drives as a "ICN25N030 ATDA04-0 USB Device"

Hardware in question:

Primary HDD: 1TB Seagate Barracuda ST31000528AS (7200RPM)
Secondary HDD: 3TB Western Digital WD Green WD30EZRX
I've been spending the last month attempting to build my first gaming PC. I'm finally at a place where the PC turns on and wants me to install Windows. So I've decided to take the secondary hard drive from my old PC (3TB) and make it my primary (and only) hard drive in my new PC, which I was told by many many PC enthusiasts that I would be able to do no problem.

The problem is: Windows 8.1 says the hard drive is not compatible, and must be formatted to NTFS. So I re-hooked the hard drive up to my old PC and attempted to convert it. But it turns out it's already formatted to NTFS! So if it's already properly formatted, why does Windows 8.1 say it's not the correct format? Do I need to erase everything on the hard drive and start from scratch? Because that is exactly what I was hoping to avoid!

One thing I noticed is that there is in fact a partition: one is 2TB, and the other is 740-or-so GB. But I don't know how to check if the partitions are formatted differently, if say the 2TB portion is NTFS and that's what I'm seeing, and maybe the rest of it is a different format. If there's a way to find out, I'd like to know.
An alternative to all this would be to use the primary hard drive of my old PC (1TB) and simply UPGRADE to Windows 8.1. But to do that, it wants me to restore that hard d... Read more

First post, long time reader. Hopefully someone can help me with the following:

I just recently got a hold of an older PC that I wanted to use for test purposes with Windows 7. The problem is that the BIOS on the PC does not recognize the Hard Drive. Upon startup I get the following message:

Primary hard disk drive 0 not found
Primary hard disk drive 1 not found
Strike the F1 key to continue, F2 to run the setup utility

Now get this, although the BIOS does not recognize the hard drive, Windows 7 and XP recognize it just fine (displays the correct size and everything). I have never seen or heard of this happening before. Usually it's the opposite (i.e. BIOS recognizes the drive but not Windows).

Windows 7 displays the following error link under the "Where do you want to install Windows?" dialogue box:

Windows cannot be installed to Disk 0 Partition 1. (Show details)

Upon clicking on the error link I get a pop-up window with the following message:

"Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu.

Hello all! I'm really hoping someone here can help me out with a problem, because it's driving me insane.

I just put together a new computer. Older hard drive (80GB IDE -- I'll replace that when I have money), but new CPU (Athlon II), memory (2GB DDR3), and motherboard (Gigabyte MA74GM-S2). The hard drive is slave to a master DVD-ROM.

Upon booting, the machine POSTs fine, both hard drive and DVD drive are recognized accurately.

Here's the problem. If I put in my Windows 7 Home Premium DVD, and try to install, it'll tell me it doesn't see any drives to install to. I get the Load Driver option and the Refresh option, with nothing in the box.

If I put in my Ubuntu CD, it boots up fine, sees the hard drive there, it'll even install to it without a hitch.

So, what are my options here, what can I do? Am I stuck with Ubuntu forever? I just want Windows 7 to install. I know it can, I had it installed on this very hard drive until this morning. What was my mistake, what am I missing?

Answer:Windows 7 Setup DVD won't recognize my hard drive; Ubuntu will.

Hello and i thank you all for your help in advance. I've found other threads with some solutions to my issue but my computer does not have a floppy drive so i cannot solve this problem via that route.

I have an Asus EEE 1005ha laptop and the hard drive failed. I just bought a new SATA 500gb hard drive and did the physical install, but now when I try to install my original Windows XP service pack 3 re-installation disk and i start running through the installation process, Windows is not letting me select any hard drive to install the operating system on. It says there is no hard drive present. It will eventually prompt me to hit F6 to select drivers so i can property do the install but anything i select from the list is prompting me to insert the re-installation disk into the floppy drive (which i have none), and then i am forced to restart the entire process.

I've read other posts that i would need to get the proper drivers loaded onto a floppy in order to move forward so Windows can see the drive. How do i get around this without a floppy? I tried loading the files I think i needed from the ASUS website onto a flash drive but windows will not recognize this drive when i plug it in. I am fairly knowledgeable with PC's but this is obviously too big a problem for me to get past.

I recently attempted to add a hard drive to my Lenovo W520 laptop using a CD/DVD caddy accessory designed to hold a SATA hard drive.

Windows recognized the new device and according to its messages, automatically installed the required device drivers. However, when I go into Windows Explorer, the new drive is nowhere to be found.

Now, I know (or at least assume) this new drive probably needs to be formatted, but shouldn't it show up within Windows Explorer even in a pre-formatted state?

If anyone can give me a clue as to what the problem might be, that'd be great.

I decided to do a clean install of windows and formatted the hard drive after backing up any data I wanted to keep. When I put the hard drive back and tried to install windows, it took me several hours monkeying around in the BIOS to even get the hard drive recognized, switching back and forth between UEFI and Legacy, and trying to change other settings to see if it would help.

At one point the drive did show up but windows wouldn't install because the current settings at the time required the disk to be MBR instead of GPT. I converted it to MBR on another computer by pulling out the drive and using an enclosure and then putting it back in the original laptop, and when I put it back in it did look like it was going to allow me to install, but I had to call it quits at that point because I had to leave.

When I came back, surprise surprise, the hard drive couldn't be seen in BIOS anymore and I ended up having to install windows to an M.2 drive I had, but I need my primary hard drive to be recognized and used as the boot device.

I don't know what other relevant info to include so let me know if there's something I need to divulge.

In windows 7 my external hard drive does not show as a back up location.  When I go to system image, the box for what items I want to back up also has the ext drive checked. I do not want to back up the external hard drive but it will not uncheck.,
(faded lettering) I believe this is why I cannot back up my computer to it.  How do I get the back up from including the external hard drive? <input id="39f7f89d-082d-4e34-8bd3-a03da4f8d21c_attachments" type="hidden" value=""

Dell Dimension 8400 (about 3-4 years old). Stock SATA 160gb hard drive crashed (got the blue screen, all the codes, etc.) Took it to a computer place, they also said the HD crashed. I have bought a replacement 250gb SATA HD - attached the two inputs to the back (one thin and ling, one thin and short) and all I get on boot up is a couple of chirps and the screen says "Drive 1 (and 2 and 3) Not Found: Serial ATA, SATA-1" and repeats for drives two and three. The drive is warm, it's being accessed (it's humming), but I've also tried a third 160gb drive, same thing. I even replaced the original drive back in and the same thing - not even the blue screen and error codes any more.

Went to F2 set up, set to auto detect, all (SATA) drives sets to 'on.'

I'm computer literate, but not a techy or anything.

Totally lost now. Please help.

My motherboard MSI 648f Neo does not appear to accept my 300Gb hard disk. I have the latest BIOS update from MSI. I need a new board that will also accept an AGP graphics card purchased a few months ago. I would like to stay with Intel as I have a Pentium 4 in this board and have been happy with it. Currently using DDR SDRAM and would like to use it on the new board. Any suggestions as to how I can get this board to accept the hard disk or suggestions for a replacement board to the above specs please.

I just put together a new PC. I used the Foxconn 925xe7aa motherboard. When I boot up the BIOS recognizes my hard drive which is a 300 GB Seagate but does not recognize my DVD burner which is a LITE-ON SHM-165H6S. I know the DVD burner works because I switched the DVD burner to the IDE 1 slot on the M/B and it loaded the Windows installation. Also I can see in the boot-up sequence that it has the DVD burner listed as Drive 0 but in the BIOS it has the hard drive listed as Drive 0. I have tried many things and none seem to work. Any help would be greatly appreciated.

Original hard drive died.  Installed new drive, which tests fine.  However, booting up from CD and attempting to restore image contained on USB external drive, but the drive is not recognized.  I have tested on another Laptop (Lenovo) which recognizes the USB external drive, so there is no issue with the external drive.  I cannot restore my HP Pavilion unless I can get it to recognize the USB drive containing the HD image.  Please let me know if there is a way to do so.

Well I got a new hard drive since my other one died, and I installed it and everything. I had another drive from before set as slave, and when I installed the new one, it couldnt detect the slave drive anymore, so I installed windows and all that on the new drive, and when I went back to mess with the drives to try to get them to show up, I was having some trouble.

I had the master on Cable Select and the slave on slave, only the slave showed up.

I had the master on master and the slave on slave, only the master showed up.

I had the master on the 3rd option other than slave, and only the slave showed up.

I have the IDE cables right, so I dont really know what the problem is, I cant get my computer to recognize either of them.

The hard drives are a 200GB Maxtor and a 200GB Seagate, master and slave respectively.

I have an old locally built desktop PC. It came with a 10GB ide hard drive, 128 MB memory, Award Modular Bios v6.00PG, Windows 98, and a 500MHz Intel Celeron processor. I attempted to install an 80 GB HD and the PC wouldn't recognize it. Now it won't recognize the original HD. Infact it makes a sweaking/buzzing noice and won't boot to the bios. With the 80Gb or another old HD (I think it is also a 8GB) it will boot to Bios but refuses to recognize the HD. The original HD is a Seagate ST310212A. The 80 GB drive is a WD800AW.

I swapped my original computer's processor with a different one and now it fails to boot to the Windows Loading screen. It will go through the BIOS screens and let me choose how I want to start up Windows XP, but after I click "Normally" or "Last Known Good Configuration", my PC crashes and restarts. I've tried logging into Safe Mode and it does the same thing. I replaced the IDE cable to my hard drive but this has not solved the problem. I haven't changed anything about the hard drive since I replaced the processor.

In the BIOS screen, it will acknowledge that there indeed is a hard drive connected, but it will not boot from it.

My specs are:
Windows XP Pro, SP2
2.70GHz Intel Pentium 4
1.50GB DDR RAM, 184-Pin
80GB Maxtor Hard Drive
SiS Motherboard M935DLU V2.0
400W ATX Power Supply

Could someone explain why my computer is failing to load XP?

Answer:PC Will Not Recognize Hard Drive!

When you install windowsXP, it loads drivers for your specific type of hardware. My guess is that the current drivers for your old processor won't work for your new one. Your problem is with software, not your hardware.

I would try putting in your XP installation disc and doing a repair install. I'm not sure If you can use recovory consule for this so I would try the Repair install. A repair install will not delete any data or software on your computer. It will replace all of your system files with the original files. It will also delete and reload all your original drivers.

When you boot from the XP disc you will get the blue screen for a while. Windows will the ask you if you want to
1)install a fresh copy (enter)
2) load recovery consule to repair a copy of windows.


To do a repair install click ENTER and continue to load a fresh copy of windows.

Windows should search for an old copy of windows. When it finds the old copy it will ask you agian if you want to
1) continue with a fresh installation (enter)
2) Repair the old copy of Windows (R)

Hit R to proceed with the Repair installation

DO NOT install a fresh copy of windows as you will loose your data.

Help - I want to back up my data and bought an USB 160GB SimpleTech hard drive. I'm running Win XP Pro and the PC added a MicroSoft driver for a"USB Mass Storage Device." That is what shows under the Device Manager. It does not show the new drive as a fresh "F" drive (after "D" -DVD drive and "E"-CDRW drive)

I ran the software that came with the drive "StorageSync" but it doesn't recognize the drive either. What am I missing?

Answer:PC won't recognize new USB hard drive

If it is the PIII computer as in the specs, it will be USB 1.1, unless you have added a USB 2.0 card.

Its possible that the USB drive requires a USB 2.0 capable port, many will work with USB 1.1 (slowly) but some do need the hi-speed port. The data with the drive should say?

My XP desktop was working fine as of last night, but when I booted it this morning it wouldn't start up. I dual boot the machine with XP and Ubuntu Linux to play around with, but 99% of the time I use XP.

I tried getting to the recovery panel using the Windows XP installation disc to try some troubleshooting there, but when I do that I get a message that Windows can't detect my HD.

I've confirmed that my BIOS recognizes my HD. Also, I can still boot and use Ubuntu no problem. So I think the HD isn't dead, there is just a communication problem that needs fixing?

Any ideas on how to fix would be great. I am a newbie with Ubuntu, GRUB, and partioning, and could use the help. BTW, this setup hasn't caused any problems since installing about two months ago.

So I have this issue where my 500gb SATA hard drive isn't seen by Win 7 (running 64 bit Pro).

The thing is, when I installed it (from what I can remember) it saw the 500gb hdd even though it wouldn't allow me to install on it.

I've tried different SATA ports on my MOBO and nothing. It's not a huge deal since I have an external 500gb but I'd rather use up the internal before. Plus it'd be nice to know what's currently on the internal one.

So any ideas on what I can do next to get it working?

Answer:Won't Recognize Hard Drive

Perhaps you need to install the SATA driver for that drive? Check the manufacturers web site.

Hello. I boguht a 40 gig hard drive and instaleld it. I tried to partition it into 4 partitions. I did 20% for the c: one and tried to do 20% on each, except that when I DO make it, it only lets me use 40% basically giving me control of 60% of my drive other than 100%. What am I doing wrong?!?!? Thank you.


Answer:My Hard Drive won't Recognize over 40 gig

You create the primary paritition first for 20%, next you create an extended partition for the rest of the size of the drive 80%, then inside the extended partition you create logical partitions for whatever size you want the remaining.

hello all, I'm trying to recover some files from a hard drive i replaced. I've got windows xp on my new hard drive, and I have connected my old one, but windows wont put it into My Computer for access. When I plugged it in, I set the jumpers according to the diagrams on the backs of each drive, but didn't go into the bios and detect the second hard drive. Windows still put an icon into the toolbar telling me it had found new hardware, then reconized it as a maxtor drive. I went into My Computer, but there was nothing relating to the maxtor drive, just my first hard drive and cd-roms. I then went into the bios, auto- detected the second drive, rebooted, and tried it again, with no difference. The hard drive is recognized under the device manager, but won't come up under My Computer. The drives are on the proper sections of the cable in terms of Slave and Master, so I'm not sure what else it could be, unless the hard drive has become damaged, or needs to be re-partitioned, which would defeat the purpose of what I'm trying to do. Does anyone know what the problem is, or what I need to do to figure out the problem?

Answer:getting xp to recognize a second hard drive

Is the Maxtor drive formatted FAT32 or NTFS ?

Answer:Win XP Won't Recognize All Of Hard Drive

I dont think it was the 32 gb limit because I when I first installed it, my orignial hd stated 80 gig as it is and the new one said 127gb, even though it's actually a 160. This is also the reason I was fiddling with the disk that came with the seagate hd. Somewhere on that disk was a program or an option to set the disk size, which i also cannot relocate that option or software again to correct what I did wrong. I do feel I had a limit of 127gb and I was wondering if what you're saying is true about updating the motherboard's bios will correct whatever I changed that caused this problem. I'm not really a computer genius, can you tell me how to find out what kind of motherboard I have so I can begin my search for those bio updates?

I'm working on my sister's XP Gateway computer GT4022. I've installed an old hard drive that came out of my old Gateway. I first installed it as the master by itself and copied my old files off of it. (My mother board had died on mine.) Therefore, I know the drive is good as it booted without any problems.

I set the jumper pins as shown on the HD case with the [Master w/ Slave] in the center of the 200 and the 250 on the second from the end. When I tried the slave at the opposite side of the center pin, the computer won't boot, so I presume I have it set right since it shows in the BIOS as slave.

When I plugged her drive WD 200 GB drive in as master and my old WD 250 GB as slave, the BIOS show it set up correctly and shows the IDE Channel for the 200 Master and the 250 Slave both as Auto.

When I go into Disk Management, it also doesn't show.

I don't know what any of the BIO information means, but am trying to give you all the info I can.

You should probably, also, know that before I connected them both, I used Parted Magic on the 250 drive to remove all the drives on it and formatted the entire drive to FAT32, but it only took a few seconds, so I'm wondering about that having worked correctly. Wondering if that is my problem.

Would appreciate any suggestions.
Just to be clear, the computer listed in my signature is not involved in this in any way. My HD came out of a Gateway GT5220.

If you are prompted for an administrator password or confirmation, type the password or provide confirmation.In the left pane, under Storage, click Disk Management.Your boot drive will show up a Disk0. Stay away from that. The added drive should show up as Disk1. Right-click an unallocated region on your 'new" hard disk, and then click New Simple Volume.In the New Simple Volume Wizard, click Next.Type the size of the volume you want to create in megabytes (MB) or accept the maximum default size, and then click Next.Accept the default drive letter or choose a different drive letter to identify the partition, and then click Next.In the Format Partition dialog box, do one of the following:If you don't want to format the volume right now, click Do not format this volume, and then clickTo format the volume with the default settings, click Next.Review your choices, and then click Finish.

I went to install the new hard drive (same model) and it will not recognize it in the BIOS but if I install the old one it will recognize it in the BIOS even tho it is dead. I go to load Windows XP Pro and it recognizes the hard drive under this. It formats it fine and everything and then when it goes to restart it wants to load the setup again. I try running the setup and then taking the cd out and it pops up the Operating System Error. I look on the website for BIOS update and could not find any for that exact model. So any info or tips I would appreciate. Thanks!

Hello Windows 7 Forum members,

For some reason my HP Laptop (Win 7 Home Premium) can't see/recognize my usb external hard drive (seagate). When I start/restart my computer and connected the usb cable into laptop, it shows the icon on bottom taskbar (safely remove hardware and when clicked on the usb icon, I see "open Devices & Printers and Eject USB to IDE bridge), but I can't see my drive at all when I click on "my computer"?

I can only see it under "right click Computer, Manage, Device Manger, Disk Drives," it only says; "generic USB Disk USB Device". And when I expanded the USB controllers via Device Manager, I can see it under USB Mass Storage Device. Sadly, I can't do much there/here unless Win 7 can see/recognize the drive under "My Computer".

<> HD is 40GB IDE Seagate (enclosure is PowerSpec 3.5 IDE to USB 2.0)
<> Drive is only storage for data, documents, pictures and softwares/programs, etc.
<> Drive is/was not formatted

Again, this drive was never formatted, only for storage purpose (i.e. pictures, documents, data, etc.). I can see it on my old computer when connected internal via IDE cable.

Please someone help me because I have a lot of my newborn daughter's pictures and my wife has a lot of important documents on the drive. All I want is to be able to see and open this drive again.

I've rotated the hard drives as well as switch the jumpers around from slave to master etc. Nada..and its not the motherboard or cpu. the only way i can get past the post screen and into the bios is to remove all 3 the hard drives. i placed a hard drive from my own pc into my bro's computer and it recognizes it. but when i place any of the 3 hard drives from my bro's pc into my own pc, my pc will not boot up, it freezes at the post screen. I tried moving the jumpers around for this as well but nothing worked. Any thoughts on whether the hard drives are toast or not? or if there's any way to retrieve the data from them?

Answer:Computer(s) won't recognize hard drive

IDE or SATA? What happened to cause this trouble? Power supply problems, motherboard?

XP won't recognize external hard drive I have a SimpleTech ext hard drive 1.0 To USB external hard drive and I am running XP sp3 on my PC. My external hard drive was working fine until this morning, when my computer decided not to recognize it at all. It doesn't show up under My Computer, nor in the Device Manager

Disconnecting the UBS connection has no effect.

Please refer to this thread:

None of this has worked.
