SATA3 drive only recognised when SATA2 drive disconnected

Question: SATA3 drive only recognised when SATA2 drive disconnected

Hi - I have just completed a new build [Asus P6X58D-E; 12Gb Ram; Corsair Tx750; i7-950; Gigabyte GTX460] to which I put a 2T SATA3 HDD. The build went perfectly and loaded windows 7 just fine. Reboots and runs well.

After all the drivers and everything were loaded and the system was stable I added two data drives with all my data on them. A Seagate 1T SATA2 drive and a Samsung 500G SATA2 drive. Neither of these were ever boot drives.

When I restart the system it tries to boot of the 500G drive and doesn't show the 2T SATA 3 drive at all in bios. If I take the SATA2 drives out it boots normally again. It also runs fine if I put the SATA2 drives in a caddy and plug it in vial USB.

Have I missed something in the initial setup/first start that is causing this? Any help would be appreciated.

Preferred Solution: SATA3 drive only recognised when SATA2 drive disconnected

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: SATA3 drive only recognised when SATA2 drive disconnected

There are no such thing as SATA 2. They are SATA3 or SATA6.

Go into BIOS and set the boot priority, those drives could have overridden it.

I suspect that my SSD drive , Intel SSD 320 120GB, does not operate at is full potential. It is plugged in the Sata3 device on my mainboard.

Looking at my Bios, I see that it is set to IDE. I did try to set it to the AHCI mode, but PC would not boot up

I did try the AS SSD Benchmark tool and I gorr a result of 163
It mention PCiIde BAD

Now, How do I know if my SSD drive is driven with Sata3. If not, how do I set it without re-installing Win 7

Any help appreciated


Answer:Is my SSD drive driven by Sata3 or Sata2: How to know

The 320 is a Sata2. If you want to go AHCI, you have to set the OS also to AHCI. AHCI : Enable in Windows 7 / Vista

Hi all,

I've just bought a Samsung 250GB SATA2 SP2504C hard drive with the intention of installing Vista on it. Problem is its not listed as one of the available drives during installation- just the other two, one of which is IDE and one is SATA. I've checked the Samsung website for Vista drivers but there are none, in fact there are no drivers full stop.

I've upgraded my SATA/RAID drivers for my mobo (Gigabyte GA-K8NXP-9), but I've stopped short of flashing the BIOS, mainly because I'm a coward. The BIOS itself doesn't list the device as an IDE drive on any slot during the first POST screen, but it is listed on the following page as a RAID drive and the BIOS also lists the drive in the "order of booting" screen.

Most annoyingly of all, I can see the drive in Windows 2000, and I've been able to format it to NTFS. I've even seen it from a Linux distro, but sodding Vista with its 1 billion drivers cant pick it up.

Any help would be much appreciated.

Answer:SATA2 Drive not recognised during install

If it is using a Sata/raid card, you will need to load drivers during the install. I would check on the disk that came with it or on the website for a driver diskette creation tool.

Today, in my Optiplex 780 Desktop with Win 7 Pro 64-bit and 8GB RAM, I cloned my hard drive from old drive to new drive.  To do that, I went into BIOS (which is the A14 version), went to Drives, enabled SATA2, and plugged the new empty hard drive into the SATA2 socket on the motherboard.  The original drive has always been in the SATA0 socket, and the CD-DVD has always been in the SATA1 socket.
The clone went well (using Macrium Reflect Free in a USB stick).  When I took out the old drive and connected the new cloned drive to the original SATA0 socket, the Optiplex gave me errors on the reboot.  It said it was missing a drive in SATA2 and did i want to Continue, go into System or run Diagnostics.  After a few reboots with that error, I went back into BIOS - Drives and disabled SATA2.  Then reboot went very well without errors, a few times.  All good.
However, those errors aren't right.  I should be able to enable SATA2 in BIOS and not get errors just because no actual drive is plugged into the SATA2 socket on the motherboard.  (That's how it works in a different Dell Optiplex 3010 I have).
So what's going on?  Why am I getting this error?

The Windows 10 version of Thinkpad Yoga 11e comes with 128GB SSD but when running a benchmark on the laptop it's top read speed is below 300MB/s.  I swapped out the SSD for a faster one (OCZ TRION 150 2.5" 240GB TRN150-25) which benchmarked faster random write times (250MB/s versus 150MB/s) but it also benchmarked below 300MB/s overall read speed.   So, is the internal bus only Sata2 which would cap the drives at 300MB/s?

I just did something really stupid and wanted to share it so that perhaps I could deter someone else from making the mistake. I'd been itching to install a SSD to house Windows and most used programs. Anyone who's ever looked at benchmard comparisons of HDD vs SSD would want to switch out as soon as possible. So, I purchased a Samsung SSD 840 EVO 250 GB SATA drive, swapped it out for my HDD, migrated the entire OS and files from HDD to SSD and rebooted with much anticipation. When Windows booted I was disappointed to see that Windows loaded just as slow as it did from the HDD. So I ran the benchmarking program that came with the drive and was horrified when I saw the results (see thumbnail pic). Turns out that my motherboard has a SATA2 port rather than a SATA3 port. I'd seen that my external HDDs had SATA3 capabilities and just assumed that I had a SATA3 enabled system. Stupid assumption. I repeat, stupid assumption. Although a SATA3 SSD can run on a SATA2 port, when it does it loses almost all of the speed gains offered by SSD compared to HDD. It's like driving a Ferrari with a 2x4 wedged under the gas pedal. So for all of you lucky enough to find a SSD under the Christmas tree, be sure to check your computer specs closely before you tear open that box.

Hi all

I am in the process of setting up a new PC and would like some advice please.

I have a Gigabyte X58A-UD3R MB which has SATA2 and SATA3 ports. I have two SATA3 1TB drives and 1 SATA2 1TB drive. I was going to keep things simple and have them all as separate drives, therefore no need to RAID them.

(OS: Win7 Ultimate 64bit)

I am planning to;
- use 1 SATA3 drive partitioned 40% for system and 60% for User Files.
- use 1 SATA3 drive for All current Photos and Videos in use
- use the SATA2 drive as storage for older Photos and Videos

So am I best to set them all up as AHCI or IDE?
What about the CD/DVD does that need to be AHCI too (have not checked if there is actually a choice for that yet)?
Or does file transfer from IDE to AHCI and AHCI to IDE work fine?

Please help, have system sitting in BIOS now trying to figure out what is the better way to go.

I have tried it with AHCI for all the SATA2/SATA3 drives and when I boot with the Win 7 Install disk it recognises the drives without a need to install any drivers for them, is that correct or is Windows seeing them as IDE still?

Note when it boots (the PC) before I get to the boot selection screen I can see an ATA loader looking for the drives and it flashes up quickly no HDDs just before I get the boot selection list... help please what is this all about?



Windows 7 comes with generic AHCI drivers pre-loaded, allowing you to install the full ones after installing windows 7. I would recommend setting the drives up as AHCI to enable the full range of SATA features. If the CD/DVD drive(s) is(are) SATA then it(they) should be compatible with AHCI, if not then most motherboards have a feature to allow the last 2/3 ports to be controlled independently from the rest, so you could put the last ports into IDE mode for the CD/DVD drive(s).

File transfer IDE <--> AHCI will be fine.

The ATA loader is looking for devices connected to the IDE header of the board. If you do not have anything connected then nothing will show in the list.

Hey everybody, I am loving my X220 greatly, and haven't felt like it's inadequate in any way, except now I need a little bit more storage space. Right now I have: 160GB Intel SSD (came with it)60GB OCZ SSD in the mSATA port I'd like to replace it with a much larger mSATA SSD, and then use the Intel SSD for storing backups or other things along those lines. The question I have, is the mSATA port SATA3 or SATA2?  If it's SATA3, I'd like to take advantage of it by using an SSD like this: Right now my boot time from the bootloader to the login manager in Linux is 4.6 seconds (very customized Archlinux install), and it's very snappy, but I can't help but wonder if I can make it faster ;-) I have the Core i7 version, if that makes a difference. Thanks!

All of the information I can find online regarding my model states that it is SATA3. Given its age, and the fact it even supports USB3.0, I can see no reason why it would not support SATA3 as well. However, after upgrading my hard drive to a Samsung 850 Evo 500GB SSD, the speeds are half what they should be, and there is a message stating that the system does NOT support Sata3.  Is this a driver based issue? Something AMD chipset related I am missing? I have run all the drivers on the HP site for my laptop. Still the issue persists. Please help!

good evening to all,
i have a strange issue with my windows xp installation and i am looking for some advice please
please let me first explain that my hd (wd 250 gb) was on sata port number 3 on my asus motherboard p8h61m-le socket 1155
i decided to install my hd on sata port2 and on sata port1 my dvdrw (samsung multi drive)
unfortunately the pc couldn't be booted ! so i reset the bios but again the pc couldn't booted
then i decided to re-install windows xp but the installation cannot be proceeded and have stopped just after it loaded the necessary drives !
the bios can see my hard disk and my dvdrw regardless of the sata ports
i do not want to delete my windows primary partition with a partition utility because i do not have any spare disk to backup my data
many thanks in advance

Answer:windows xp can be installed on sata3 hd but not on sata2 hd !

If you can get into the BIOS, can you get the computer to start in safe mode by tapping the F8 key while the BIOS screen is showing ? Tapping the F8 key should bring up a black screen with white text. At the top of this there are normally three safe mode options with repair options at the bottom.
I would be inclined to choose first 'Safe mode with networking' just to see what happens. If it does nothing or freezes, switch it off and try again, this time choosing 'Repair Windows' and see where this takes you. It will either fix the problem, offer you other choices or tell you it can't fix it.
If it refuses to start in safe mode or repair itself then you may have to consider ways of recovering your data of the drive before you re-install. Post back and say where you get to.

I have been given a voucher ($200) for my local computer store as a birthday present and I want to know if it is worthwhile installing a SATA3 SSD on my Gigabyte PA 55 UD4 motherboard that only supports SATA2?

I won't be upgrading my motherboard for approximately 3 years when I purchase a new computer, so that is not an option. I guess it would future proof the hard drive but is it likely to last three years and more?

Would I notice a big difference between an SSD SATA3 and my Western digital 1 TB Green SATA2 connected to my existing motherboard?


Answer:Should I install SSD SATA3 on SATA2 motherboard?

Yes, it would be a huge difference. You would boot to windows in under 30sec.

Hi all.  I am doing performance testing between the 520 and 530 and noticed that the 520 (using SATA2) is actually a tad faster than the 530 which has SATA3. Yes, my 2 SSDs are SATA3 compliant and are the Kingston SSDNow v200 model.  Both machines are Win7 and the 520 has 24GB ram while the 530 has 16GB.  The 530 was just delivered to me a few days ago so it should be a very current build from Lenovo. The speeds on my 520 (using CrystalDiskMark 64bit) are:Read=320MB/secWrite=205MB/sec Ideas?  I've done numerous tests and the 520 each time beats the 530 by a few MB/sec. In theory SATA3 is 2x as fast as SATA2...but I'm actually seeing a DECREASE.  So it's either the drives or the 530.  I was realistically expecting to see a 1.25x gain instead of the theoretical that would be about 400MB/sec Read and 250MB/sec Write. If you have better results, I'd appreciate you listing the exact make/model drive(s) you are using.  Thanks!  The Kingstons I am using is the link below.  Thanks again in advance!

Answer:W530 SATA3 slower than W520 SATA2

The W520 supports SATA rev. 3.0 as well, or you would never be seeing any speeds above 300 MB/s. I'd imagine the only real differences are the NAND in the individual SSDs. The speed you mentioned is roughly the quoted speeds for your SSD, according to the Newegg product listing you linked to. The only way you'll see better speeds is if you get a faster SSD. If you're on a budget, I'd recommend the Crucial m4. Otherwise, you can't go wrong with the Samsung 830 or Samsung 840 pro. The Samsung 830 in my system has sequential speeds of 500MB/s read and 400MB/s write.

Not many of us know that HP put out some advisories about significant "issues" related to using non-HP SATA generation 3 hard disc drives in their xw generation of SATA generation 2 workstations.  The use of HP or non-HP SATA2 drives in these SATA2 workstations did not produce the problems, and the HP advice was to only use HP source SATA3 drives in these SATA2 workstations.  The HP firmware engineers seem to have figured out the solution, but that was via HP firmware, reserved for HP sourced drives.  It was not that all non-HP SATA3 drives would see this issue, but the wording indicated quite a large percentage would. The Z400, Z600, and Z800 workstations also are SATA2, as is the Z200, and many others.  You start getting SATA3 on the ZX20 generation.  It turns out this issue also applies to some non-HP SATA3 SSDs: We came up against it initially in some xw workstations in which our IT guys used non-HP SATA3 Samsung EVO 850 SSDs with the included EMT01B6Q firmware, which crippled the workstations badly.... very slow boot, odd loss of USB ports, etc.   If the same Acronis image was cloned onto my favorite Intel 320 Series 300GB SATA2 SSD there never was a problem in these and other HP SATA2 workstations. We had to remove the SSDs, have them attached as a secondary drive to a utility workstation, firmware update them to EMT02B6Q, then DBAN low level...

The SATA series of adapters are a new type of connection between the hard drive and Motherboard drasticly improving transfer rate and a far better multitasking rate the higher the series. The difference between the I, II, and III is speed (Transfer rate). Series I have a transfer rate of 1.5 GB/s(BUT only in short burst with a typical rate of 1.2 GB/s, series II a rate of 3 GB/s and finally series III a transfer rate of 6 GB/s. Anyone else is free to correct me, the numbers are being pulled off SATA's websits . Good place for info on their products and what they're capable of.

How could I know if my drive is driven by a sata3 or sata2?


Answer:How to know if my drive is driven with sata3

You need to know the specs of the SATA controller in your system (usually built-in to the motherboard) and you need to know the specs of the drive itself. The Gigabyte B75M-D3H motherboard you have listed in your system specs say that 1 connector on the board (it will be a different color than the others) supports SATA 3.0. Provided the drive you have plugged into that connector also supports SATA 3.0, you should be good to go.

Answer:Hard drive and optical drive only work when IDE cables are disconnected


check that the cables are plugged in the right way round, the red stripe on the cable goes next to the power socket on the device and the board is usually marked pin 1 or has a dot on it.

does it happen when you plug in a single device or only when you plug in both.

are you using seperate cables or are you putting both devices on the same cable.

I use Acronis backup and I set it to backup to drive Z. Then go into Disk Management and assign your backup drive to be drive Z. Usually this will never change due to removable drives.

It's not 8 gig.

It's 8 MB.

I have read explanations of why that occurs. I don't recall all the details, but if memory serves there isn't much you can do about it. I think some Disk Management/Partition Management programs won't even see it.

You might (?) be able to get around it with a clean or clean all command from Diskpart?

It's so very small, I'd forget about it unless you are obsessive, like me. In which case, others may remember if there is a specific solution.

Answer:sata2 drive

Does the drive have jumpers to change transfer rates?
Does the mobo support sata 2?

My harddrive has packed up...annoyingly just outside of 12 I am looking to get a replacement and thinking of going down the SSD route...does anyone know if a 128gb 2.5" sata3 will be compatible? Thanks for your input!

Answer:Satellite L655-18J - Will be 128gb 2.5" Sata3 SSD drive compatible?

SATA controller is backward compatible? So even if the notebook?s SATA controller would supports only SATA I or SATA II performance, the SATA III SSD drive should be compatible too but you would not get the performance of SATA III interface.

However, the SSD drive should work too.

I am wondering if someone can help me with this issue.

I had a desktop with ASUS P5GC-MX/133 motherboard installed with two physical hard drives - 1 IDE and 1 SATA2. A year ago I installed window XP SP2 on the IDE hard drive and used SATA2 as storage (not RAID). When I installed the window XP, I did not press F6 to load 3rd party drivers. And I used Device Manager to format the SATA2 drive and partitioned it into 4 partitions.

Last week, there was something wrong with the OS so I reinstalled window XP. However, after reinstalling the OS, the BIOS and window's device manager can detect the 320 GB SATA2 hard drive (but the drive did not show up in My Computer). However, instead of showing the 4 partitions where I have saved important data, it said that the hard drive is not ready.

Can anyone teach me how to get the partitions out and shown in My Computer?

Help is greatly appreciated!.


Answer:Issue with SATA2 Drive

See if your drive shows up under Disk Management. Right click on My Computer on your desktop and select 'Manage', then select Disk Management. Also if it shows up under device manager it should say "This device is working properly". You might want to check if the proper drivers are installed and update them if necessary.

I have the same board as you, I use the RAID and have it set for RAID 0 striping for performance using 2 Seagate 80 gig SATA drives. If you look at your manual Page 5-21 it gives details of the different RAIDs and their advantages. There are no seperate connections for the RAID if you use it, you either set it on or off in BIOS.

Hello all,

I just got a SATA2 1TB HD but my motherboard (MSI KT3 Ultra I think) only has IDE ports. What's the cheapest solution to link the two but still utilizing SATA2? I could go USB2.0 (solution: external enclosure + USB2.0 PCI card since my MB only supports 1.1) but I would much have the faster connection of SATA2. Also, if I do have to add a SATA2 PCI expansion card, it should recognize the whole TB right? I know in some instances with older MB's, if you plug in a HD it will only register X amount of GB's. Any input is very much appreciated. Thanks!

Answer:How to add a SATA2 hard drive to IDE-only motherboard.

Buy a quality sata controller card. Yes, the card should "See" the full size of the drive as long as you read the specs on the card and it says it will recognize drives of that size.

I use and recommend either promise or highpoint controller/raid cards. There are cheaper ones however you get what you pay for.

I recently bought a brand new Dell Dimension 5150. It has a Seagate Barracuda 320GB SATA primary hard drive and I have just added a Seagate Barracuda 320GB SATA2 slave hard drive. On the slave drive there is a jumper that limits the data transfer rate to 1.5 G bits per second (for motherboards that don't support auto-negotiation), or you can remove the jumper for 3.0 G bits per second operation.

My question is what should I set the jumper to, does the Dimension 5150 support auto-negotiation? How can I find out?

Many thanks

Have been running a Corsair Performance 128GB SSD SATA3 HD for almost 2 years on flagship with Win7 OS. Installed a 2nd Corsair Force SSD SATA3 HD about a year ago for storage. Each had single primary partition and worked without problem.

Installed Win8 Pro OEM from retail disk when it was released late last year. And have successfully used Acronis 2012 rescue CD on this set-up to create/restore backup images. Acronis 2012 could not be installed on active Win8 GUI as it is incompatible with Win8 ... hence the need to do backup/restore with rescue CD.

A few days ago I retired older SSD HD to my backup PC, and installed newer version Corsair Force GS 128GB SSD SATA3. Successfully installed Win8 on this new disk from an Acronis image created on the Acronis 2012 rescue disk. Then formatted the SSD that originally had Win7 on it, in order to use it for storage. And copied all Acronis back up images onto this SSD from external USB HD.

Finally, purchased and installed Acronis 2013, Plus Back, and all updates, on Win8 on the new SSD HD. All good.

However, when I booted the new Acronis 2013 rescue CD to access the Acronis images stored on the storage SSD HD.... OR ... the Acronis 2012 rescue CD ... the storage SSD HD could not be detected!

Hi all

I had an old laptop that died by water damage, its OS was Vista. I removed its internal hard drive as it contains valuable photos. I read that you can convert internal hard drives into external USB ones so I purchased the necessary 2.5" sata case from ebay, put it all together and plugged it into my new Windows 10 laptop. The new laptop does not want to acknowledge the drive. I changed the drive letter to one that wasn't used, 'M' in this case, it shows as Drive M on my file manager but when I click on it it only asks me to put a disk into the drive. I have run a couple of scanning programs on it, Stellar Phoenix data recovery and Recuva with no luck. I do not want to lose the data that was on there so can anyone help with any solutions?

Hi all, new member here and am very emotional lol!!

I got windows installed fine onto the master disk and all works well until I try to plug in my second drive (which has all the original windows files on it and needs formatting). It then tells me there is a system disk error, or it just wont boot up at all.

I've checked all my cables, power leads and the master/slave switches on both drives and all seems fine there.

In the advances cmos it has the following listings -

first master - none (won't auto detect either)
first slave - samsung (this is what windows is now installed on, and should be set as master)
second master - dvd-rw
second slave - cd-rom drive

Hey guys, before I take this pc to the repair shop, I thought I'd give it a shot.

I recently purchased Samsung HD753LJ 750GB SATA2 7200rpm 32MB Hard Drive. The issue is that PC freezes when I try to copy large files.

I am a composer and audio files are quiet big. I was trying to copy folders from Western Digital mybook 500GB hard drive to this new samsung drive, and it basically hangs after 1GB or less. One time I was able to copy more than 40GB at once but again it stopped copying. However copying to main SATA drive(Seagate 320GB SATA HDD I am using 320GB HDD as the main master drive.) is no problem, I can copy all flawless, without any issues. Unfortunately I don't use RAID setup because some audio related softwares aren't so uptodate and tend to experience bad things

system hangs every time I tried to copy a big chunk. how it hangs is following.
1)copy files through teracopy
2)teracopy stops in the middle of copying process
3)some programs still work, but usually they all stop working eventually
and I can't restart so I have to do it manually, which I really hate to do it to this PC, since it's getting expensive and I need to work music with this PC. I don't want to buy another HDD to fix this stupid issue. btw I don't play any games on this. I built it specifically for audio use.

I tried just copying from C- D manually as well. but it also failed. The total file size average were 40-50GB. but I also tried to copy small chunks and sti... Read more

The Problem:

When I start copying a file of roughly 100MB or more from my primary hard drive to a secondary one, or even if I'm copying it to itself, the copying progress bar zooms along at a normal rate. The little green blocks and the time remaining are what you'd expect. Then as it gets to a certain point, it slows down and down and down. The time remaining that might have been 5 seconds doubles and doubles and before you know it it's got several minutes remaining. What started out as a 5 or 10 second estimate, becomes a 7 minute estimate, and the file really does take more than a minute to copy.

I've ran some disk performance check tools and ran chkdsk and find no problems. The file copy never fails. It's not only file copy operations either, I've noticed that when viewing a video of for example 350MB, if I drag the position slider along in 1 or 2 minute amounts, then the video instantaneously starts playing from the new slider position. If I drag the slider beyond a certain point, it can take a good second or two before it manages to start playing from the new position.

Now to the background info that should answer any follow-up questions:

- The machine is a dual-core E6600 Intel box, so it's not slow.
- The "system idle" process is rarely ever under 98% during these operations.
- If I have several copies occurring in parallel, they'r... Read more

Ive got Vista Home Premium and when running the computer on moderate capacity, say FM2007 (RAM intensive game) and downloading a file i usually get these errors which foul up my system and actually prevent the system from rebooting from the start menu (it hangs on the "shutting down" screen).

Most people seem to have this issue with CD/DVD drives and Floppy's and i cant seem to find much help out there for a SATA2 related issue.

Its my understanding that and I/O is a lack of power supply to the device, correct?

I have 6 yr old Dell Dimension 6400 with a failing hard drive so I bought a new hard drive and decided to clone my drive before it failed, but I've ran into a few problems and I hope someone can help me before my old drive breaks!

I fitted the new drive as a slave drive using the "cable select" jumper setting as suggested in my Dell manual and managed to get the drive running fine. I can see it in the bios and my computer.

I cloned the drive using the free version of HDClone which appeared to run smoothly and afterwards I could see all the information from my old drive was on the new drive.

I opened the computer and unplugged the power from the old drive and changed the ribbon cable so the new drive would be the master drive and booted the computer but it said "boot disc failure" several times and a black screen.

I have a Gateway 866- Pentium 3-Win98SE.I originally had a Phillips CD-RW and was using Easy CD Creator V5.Windows suddenly stopped recognising it as a CD-RW drive.I tried uninstalling the CDRW and re-installing it - NO LUCK !!

It came with Nero software so I installed that too and that caused even more problem as I hadn't uninstalled Easy CD.I phoned Gateway's helpline and they said that the Windows file was probably corrupted and all I could do was reinstall Windows - which I am loathe to do !!

If we try to fix this and what ever fix we give you to try does not work and it takes down their network, boy the trouble all of us are going to be in to say nothing about the trouble you will be in. I know your boss asked you to fix this. Did you get that i n writing?

I honestly think that getting a local company with the proper tech training will be the best thing for your boss to do.

My backup drive(500gb) says it is disconnected. I am unable to run my backups. I am using Win 10 pro on a HP desktop. I have replaced the drive, but it still says disconnected. I can see the drive in explorer so I know it is not physically disconnected. How do I reconnect it?

Good day dear All!

I am facing a big problem with windows 7 & a program which we are using in the company i am working on. As it seems, in windows 7, by default, after 15 minutes, a network drive becomes idle (a red X appears) & the only way to activate the
drive again is to double click & open it.
Recently, we have installed a program, which creates a network drive in order to store all the files which are attached inside that program (creates copies of the files inside the network drive). In case we need to perform some action to the program
(for example to attach a file to the program which supposed to copy that file inside the network drive), we receive an error that the drive is disconnected & we have to go to the drive, double click to activate it & then again to perform the action
through the program.

Is there a way, a fix, a small *.exe file, which we could download & run in our computers/servers in order for the network drives never to become disconnected?

Thank you in advance for your time!

Best Regards

I disconnected a mapped drive. checked registry and it does not show. checked via net use /delete and it does not appear to be there.
however when I do in CMD> DIR R:\ (where R:\ is the drive letter) it lists the content of the mapped drive and I can access from all programs as well.
How can I disconnect this mapped drive?

I have 3 drives mapped on a WinXP Media Center Edition machine, which always show up as Disconnected Network Drive with every boot. I can access them if i double click them, and then they are marked as connected.

This is a problem, however, because when i load up Media Center, I have these 3 drives mapped under My Video, and they won't display. What I am doing now, is remoting into the system every time I boot it, opening each mapped drive, and then launching Media Center. But, this is a pain in the ***, because I jsut want to boot up and go with the remote control.

Does anyone have any advice?

I mistakenly Disconnected a previously connected NAS drive that had been assigned as Z:/. Now Win 10 doesn't even recognize it as an available drive on the network using either This PC or File Explorer. However, it is shown as a netwrok device using Control Panel/Network and Internet/View Network Computers and Devices. Though the drive can't be reconnected to the computer through Control Panel. Any suggestions how I can recover the NAS drive? Thanks


Go to Solution.

Answer:How To Recover Disconnected NAS Drive

normally a NAS is not mapped as single drive but folders are shared as:network foldersornetwork drives if you know the NAS IP, you can add this to the Map a network drive, directly(example)\\NAS\sharedfoldername\\192.168.x.x\sharedfoldername  have you tried on file browser to type \\NAS\sharedfoldername - \\192.162.x.x(IP)\sharedfoldername and check if it connects?

Something rather strange has been happening recently on our Windows 2000 AD network. Certain people are calling up our help desk and complaining that their network drives (ran by a batch script at log on) are displaying as "disconnected" in Windows Explorer (see attached image). However, if they double-click to open this drive, it opens with out error. Clearly, the drive is not disconnected or unavailable by any means.

Is there a way to get rid of this "disconnected" status so that I am not bombarded with these false alarm calls?

Thanks in advance...Wayne

Hello,I have a separate drive for my programs.  Occasionally (once or twice a month), I get this message " c:\f-drive\JR>cd\jr The system cannot find the path specified".  If I hit cancel and reboot it will operate as normal.  This time no such luck.Looking at My Computer shows that the drive is disconnected.  When I type "start, run, command f: \\the actual computer name\f-drive" , it asks me if I want to overwrite the remembered connection. I did not do so..was hesitant.When I click on My computer, highlight the drive and select Map, for Drive it's set at Z, I changed it to F: \\computer name....for folder, the only choice is the name of the computer...then I check "Reconnect at logon", when I click on Finish, it says "The mapped network drive could not be created because the following error has occurred: The network location cannot be reached."Any help, comments, or suggestions would be appreciated.ThanksJennifer

I have a small (wireless) network in my home. I have mapped a network drive on my husband's computer back to a data file on my computer so we can share a specific program, but every time he restarts his computer the drive is disconnected, so he gets an error when he goes to use the program. To work around this, he simply has to go to My Computer and double-click on the disconned drive and go back, and it reconnects. I've heard this is a known XP problem; is this true? Do you know of a fix?

Answer:Disconnected Mapped Network Drive

i have found adding the drive to my network places works a lot better then mapping a network drive. no idea why, but i have changed my home network to have all drives i want continously mapped connected via network places - also this has the beniefit of nolonger prompting the connection at login.

I have a problem with WinXP connection to a Win2003 Server Shares. I am not sure as to why I get this. I am still able to access the shares. But what I see is just "Disconnected Network Drive." This shows up on all the computers in the network. I have sifted through tech articles everywhere and I haven't found a fix. I am not sure if it is on the server end of the client end. I thought I would hit the forums before I made a $250 phone call the MS. I've attached a picture of what I am seeing in My Computer. Also I have included a command buffer of the errors I get.

Since fall creators update I am seeing one of my mapped NAS drives always in a disconnected state after a reboot. It?s easily fixed by clicking the drive displaying the red x in explorer to establish the connection. But it seems strange that this has only started after fall creators and is the only one of three mapped drives doing this. And this same mapped drive is mapped in identical state to another machine running fall creators with no such issue. Any ideas on how to fix this? Or why it is happening. It?s only a minor niggle and can live with it as there are no pressing dependencies on the mapped drive but would be nice if there was an easy quick fix

Answer:Mapped Drive get disconnected after every reboot.

You could setup a batch file to run at login that does a net use to map the drive.

auto run a bat script in windows 7 at login

C:\WINDOWS\system32>net use /?
The syntax of this command is:

[devicename | *] [\\computername\sharename[\volume] [password | *]]
[/USER:[dotted domain name\]username]
[/USER:[[email protected] domain name]

NET USE {devicename | *} [password | *] /HOME

Get the drive test utility from the manufacturers website and run it. If it fails you may be able to low-level format the drive and make it useable again. All data would be lost though

I had twin SATA drives (40G) installed, thinking this would be very clever for backups and be more efficient (reading operational data from the second drive drive whilst the primary System drive also contained the back-up data partition). That doesn't turn out to be very clever at all! Using an old Paragon 5, it requires constant disconnection and re-connection so that the PC cover screws have not been fitted for years! On top of that, there have been problems with booting and with the re-naming of partitions.Does any latest clone software eliminate this physical reconnection issue, or do I give up and use get an external drive? And just where do I find a definition of the difference between a clone, a mirror and an image?

Answer:Twin drives — must cloned drive be disconnected?

I`m not totally certain about Paragon but for Acronis when you clone a drive, the PC will reboot on completion and use the `new` drive. The `old` drive needs to be reset as it contains exactly the same as the new copy and you can`t have two C: drives. Also worth mentioning is that cloning is generally used when replacing a HDD.For backup purposes an image is produced which should be kept on a separate drive (not partition) or external HDD. This can generally be `updated` with `incremental` or `differential` backups although it takes very little difference in time to create a new archive. Using this method of `backup` rather than `cloning` is less time consuming and doesn`t require opening the PC each time.The only other method open to you would be to use RAID click here but it reduces the space available and doesn`t sound as if it`s what you`re trying to achieve.

When I remove a USB hard drive from my computer, the drive letter is not released. It appears as if the table (the registry I assume) where the drive letter assignments are stored is not being properly updated.

Dell Latitude D810
2GB Memory
XP Pro SP2
Spyware Doctor
Three USB drives connected to powered USB hub connected to docking station
No mapped network drives

A couple of observations:
- If I use disk management to change a drive letter, the original drive letter then shows up in the list of available drive letters, but if I try to use it, I get an error stating that the drive letter is already in use.
- If I use disk management to change a drive letter, the list of drives that appear in the Safely Remove Hardware system tray icon does not change. The old drive letter is displayed, but the new one is not.
- If I disconnect a USB drive and then reconnect it, and it is assigned a new drive letter, neither the old nor the new drive letter will show as available in disk management.

Your suggestions would be most welcome!

Bob Chmara

Answer:Usb Driver Letters Not Released When Drive Disconnected

In the task bar there s an icon called Safely Remove Hardware. You should click on this to release the drive letter assignment form the device you are removing. This also should be done so the drive gets turned off so it can be safely removed.

This strikes me as a strange issue. On one of my 'workhorse machines', (I use RD to connect to):

1) The previous OS was XP. From XP, I mapped a network drive (designated L:\).
2) The drive was not set to reconnect at logon
3) I installed Windows 7 Pro (which, of course, required a format of drive C:\)
4) Although I did not remap the drive, amazingly, the mapped drive (L:\) still apppears in explorer. The drive letter on the previously mapped to drive was changed and not shared.
5) It does not show up in the 'Disconnect Network Drives' dialog
6) Right-clicking results in only two menu items: "Expand" & "Open in New Window"
7) Left clicking on the icon results in:
\\tsclient is not accessible. You might not have permission to use this network resource. COntact the admin of this server to find out if you have access permissions.

Attempt to access invalid address.

8) Re-sharing the network resource and remapping to it works and allows me to disconnect the drive.

9) There still seems to be no way to remove the drive icon from explorer.

Not a huge problem, as it just sits there and does not try to connect at logon (as per settings), but since I have no use for the icon, I'd like to get rid of it.

ANy ideas?


Answer:Removing Disconnected Mapped NW Drive Icon

No ideas on this? Perhaps the reference to its previous existance in XP is confusing (it is to me...). Maybe forgetting that will help and boil it down to this:

I have a mapped drive that is no longer mapped or shared, yet the icon in WE remains. How does one eliminate this icon?

I had a drive mapped to my computer and had set up a sync partnership with it. I have since removed the mapped drive but the system still has that sync entry in Sync Center. I have tried to remove it but can't. Can't turn off "always available offline" either.

I can see the previously mapped drive in the network but it's only a ghost of the drive itself and nothing I can get rid of there either.

I also tried to delete the offline files through sync management and it goes through the motions but stays in the sync center.

Hopefully the screenshots explain this better.

I'd entertain the option of completely removing all signs that anything was ever synced and start again with a clean slate but I don't know how to go about that aside from using a restore point.

Lastly I tried toggling off and then on the whole Sync feature.

Any thoughts? Thanks.

Answer:Cannot remove sync partnership. Status: Disconnected drive
