Windows 7 64 bit USB external hard drives lose its connection and stops working.

    Question


  • This is a very serious error for users of WIN 7 64 bit only.
    I have read hundreds of posts about this problem an not a word about it from MS.
    We have tested this problem on four different computers and three different external hard drives using Win 7 Ultimate.
    Even tried the RTM version.
    If you connect "Any brand" external USB hard drive to "Any brand of computer" using Win 7 (64 bit only) and try to copy a large file like a movie from the internal drive to the external USB drive it loses the connection to the USB.
    We even reverted back to Vista 64 bit on two computers for testing but Vista 64 works fine.
    This occurs on all computers with different USB drives.
    We have tried all the suggestions posted and none work.
    It seems from all the posts that other USB devices are also having similar problems with the 64 bit. 
    Below is a more about this problem.

    Thanks

  • Get in line my man, we're all trying to resolve this.  And this is a BIG problem in my view and yours too probably, so why isn't the dev team get cracking to get this one problem fixed?  I don't know if they are or not but a post on progress would be nice to those who worry most. But seriously, in my honest opinion this should be an issue resolved as first acknowledgment, if this gets out in the final retail version then I'd think we'd all have the to say 'we told you so.'

    Please, this is so annoying, I use my external constantly for archiving work, media and various books. I find that Windows 7 seems to be the current overkill operating system for me at the moment, being fast and responsive, all these things make it great but with such a small problem I'm actually struggling to use this OS everyday.  I really like it, everyone does and I think this needs to be fixed immediately.

  • I am using a final release version of Windows 7 Ultimate which I received under Microsofts Windows Launch Party so it was not fixed for the final release. A very big problem and I only hope it will be fixed through an update shortly!! It also wont let me trnasfer any music files to my IPhone through Itunes - same issue!

  • The link only refers to USB problems with nVidia chips, so it's not a universal problem.  I have Win 7 x64 RTM installed and I just transfered 2 4GB DVD files and 1 18GB backup file from my internal SATA drive to my external USB drive with no problems - no time-out!

    Since nVidia chipsets seem to be the culprit, nVidia and the motherboard manufacturers need to be told about the problem so that nVidia can correct the problem and not Microsoft.  If it's a nVidia chipset driver/software problem, Microsoft is not going to fix anything since it's not a universal problem.

  • I found a temporary fix.   Well it worked for me. 

    1.  Goto control panel/system and security / power options

    2.  Change power setting.

    3.  Change advanced power settings

    4.  Scroll down to USB settings and disable the USB selective suspend setting.

    Don't know why this did it but it fixed my issues.

  • Same problem as jh6284.  I couldn't copy/move any big files from my internal to the either external drives( i have 2 ) it would start and stop at 99%.  and just hang there.  and also quite often the drives would be recognized but not readable.  Seems to affect bigger files for some reason, files such word docs usually worked.

  • Thank you so much mark! The hotfix absolutely works perfectly even though it's still experimental.  And to think, I went to my computer manufacturer, my board manufacturer and even my chipset manufacturer! So I was right from the beginning, my hunch was in fact the drivers themselves.  Thanks so much mark! It works.  Now that people see "thank yous" in my thread, they'll assume I've fixed the problem. And to makes less work for those immediately searching for the solution, I'll post a direct link to the knowledge database article for the fix: http://support.microsoft.com/kb/976972

    And also, I had an issue downloading the correct hotfix, even though I was on a 64-bit operating system, the browser I used, firefox, was 32-bit and allowed me to only download the 32-bit fix.  So word of advice before anyone downloads the hotfix, I'd use internet explorer since it's natively 64-bit or some other 64-bit browser to download the 64-bit version of the hotfix.

    And again, thanks Mark.

    Thanks for the info.  I'm glad that you have a workaround that's resolved your problem, but I wouldn't have expected that to have any impact on your particular issue.  I'd like to get a better understanding of what's going on.  If you have the time, would you mind capturing some additional data for me please?


    1) Undo your workaround (turn selective suspend back on)

    2) Reboot the machine with the device disconnected

    3) Run this command from an elevated command prompt (right click on command prompt shortcut, select "run as administrator"):
    Logman start USBForumTrace -p Microsoft-Windows-USB-USBPORT -o USBForumTrace.etl -ets -nb 128 640 -bs 128

    4) Run this command from an elevated command prompt:
    Logman update USBForumTrace -p Microsoft-Windows-USB-USBHUB -ets -nb 128 640 -bs 128

    5) Execute your repro scenario (in your case, plug in the drive and then try a data transfer).
     
    6) After you have a repro, run this command from an elevated command prompt: 
    Logman stop USBForumTrace -ets

    7) Search on the machine for “USBForumTrace.etl”

    8) Post that file and c:\windows\inf\setupapi.dev.log on a public folder on http://skydrive.live.com and post the link here.

    Thanks,

  • Hello, there is a 64 bit version of fire fox, it's called Namoroka . It works pretty well

  • I'm running a Dell Latitude E6400, originally it came with Vista x64 and I had no problems with external hard drives and portable music players.

    I did a clean install using Windows 7 Professional x64. Have all the updates installed, up-to-date BIOS and all drivers from Dell.

    Even thru my system doesn’t have a nVidia chipset (it has an Intel® 45 Express Chipset), I downloaded and installed the hotfix KB976972 but it didn’t work for me.

    I tried to disable the USB selective suspend setting, that didn’t work either.

    My system is running a Intel T9550 @ 2.66GHz, 4Gb of RAM and Windows 7 Professional x64.

    Here are the files you asked. Hope you can find a solution soon:

  • I have found if you plug in the power cord to the external hdd it will not lose connection.

    I have used 3 different external hard drives and all need the extra power cord plugged. Sort on inconvenient but until they figure out a fix for it.

  • I hear you. The problem is that my hdd are 2.5" laptop drives. They don't have an AC input, just the power that comes from the USB itself.

    Thanks,

    Friday, April 16, 2010 10:44 PM
  • Yeah it depends on what kind of enclosure you have.  The 2.5" hdd enclosures I have all have the additional ac capability. Don't need to have it plugged in for it to work but if in this case it needs to be plugged.

  • I am experiencing a problem similar to jh6284 only my chipset is not NVIDIA and the Windows solution for that will not even install on my Dell Inspiron 17R.  Can Microsoft revisit the issue and see if other chipsets may have similar problems with (hopefully) similar solutions?

  • I am also having this issue while using an IEEE 1394 port connected to a FireWire 400 port on my external hard drive enclosure.

    In both cases (USB/IEEE 1394) I started copying files from the external drive into my hard drive and after a couple of minutes the drive will lose connectivity.

    I will go and buy an  eSATA enclosure today and see if it works, otherwise I will try the memory fix issue suggested in the other thread, but what a pain.

  • I am having this same problem with an eSata drive.

    Brand new Dell XPS8300 computer with a built in eSata port.

    Returned the first computer, and purchased a second identical computer = same problem.

     

    The eSata drive always stops working usually at 1 pm everyday (I have nailed it down bewtween 12:30 and 1:15 pm) guaranteed.

    Every once in a while it will stop working at other times, but guaranteed at the above mentioned time.

     

    I have even replaced the external hard drive and same thing.

     

    Does anybody know what to do?

     

    My other computer did not have this problem and is was on Windows 7 Home 64 bit - and it was the same drive.

     

    I installed an eSata card on that computer.

  • I have the same problems but with Z77 Intel chipset, with USB 3 connected drive (with external power) reconnecting on large writes, mouse reconnecting without any reason, webcam freezing, and keyboard disconnecting sometimes as well. All these devices have worked OK with Windows 7 32-bit on another motherboard.

    Is there anything I can check/try?

    I think this answer is a smoke screen, here's why. The issue of a USB HDD losing its connection AND not being recognized on a booting Win 7 x64 in any of its incarnations is a Microsoft issue, not nVidia. I have three PCs (actually 4 but one is in storage so doesn't count) to see firsthand what happens with this issue. One, is a maxed out Toshiba with Windows Pro x64. Every now and then, it asks to format any number of my USB drives. I have Seagates, Iomegas, Western Digitals, and an OLD Maxtor. The Toshiba OS will from time to time claim the Iomega and WD drives need formatting or have a wrong parameter etc. It doesn't do this with the Seagates or Maxtor. does the Tosh have nVidia chipsets? Yes. OK, now I attach these dives to my Dell Inspiron run by Windows Vista Home Basic and intel Graphic Chip. The HDDs fire up right away. OK, I stick them into the ASUS G75VW-RS72, a DTR notebook on Windows 7 Ultimate x64. The machine has nVidia chipsets. Sometimes the HDDs fire up right away (Maxtor is never a problem), sometimes they don't. What do I do? Unplug, replug-sometimes works sometimes not.  Turn off the computer, turn it back on-sometimes works sometimes not. Unplug and put into another USB port-sometimes works sometimes not. Unplug and leave unplugged for anywhere from 10 seconds to half an hour-sometimes works sometimes not. Switched to different external enlosure or the same or different brand-sometimes works sometimes not. Remove the HDD and put into a NetStar portable dock with its own power supply(http://www.vantecusa.com/en/product/view_detail/295). Result? The computers NEVER, not EVER, even ONCE demonstrated an issue with the drive. Other times, I remove the HDD and employ a converter (http://www.sabrent.com/category/hard-drive-enclosures/USB-DSC5/). Result? The computers NEVER, not EVER, even ONCE demonstrated an issue with the drive. So I think the evidence suggests Windows is finicky and Microsoft is passing the buck on this.

    And works indeed, it unfreezes my computer but my 32bit formatted USB (after inserted in 64 bit system) still cannot be read on my 32bit windows 7.

  • Hi There

    Its NOT just an NVidia issue at all, I have the same issue which only occurred after upgrading my External WD 1TB Elements HD to a new External WD 2TB Elements HD.

    My System, a Dell Inspiron 620MT is AMD not NVidia, The Drive itself passes all WD Tests fine so I know it's not the drive, and I have exchanged the drive via WD under an RMA Warranty, the replacement is just the same.

    I have read about this issue occurring not only on USB 2.0 but also on USB3.0 and eSATA connections and Not just WD but Seagate and a load of other external USB Drives, it's a major problem and Microsoft have not got a clue about a fix for it.

    The only common item is Windows 7 64Bit, so I think it is a Microsoft problem, also they have had similar issues before Win 7 64Bit because there are fixes for this issue in VISTA.

    Finally, although according to MS my USB driver is "Up To Date" it's a generic host controller dated 2006????, is that really the latest driver??

    Hopefully, MS will take this up and sort it out, but I do not hold out much hope of it getting done, I have decided to live with it as my backup system emails me when it fails to write to the backup drive so I know it's failed. all I then have to do is unplug the USB cable & plug it back in a gain, "IT'S MAGIC , the drive then comes back to life and can be written to, well at least until the next time it happens.

    If anyone ever gets a fix for this please let me know marlin1143@sky,.com, I will buy them a beer "or Two"

  • I cannot see this as an NVidia Chipset Problem as I have exactly the same issue using Win 7 64Bit Ultimate on a Dell with 8GB Ram running on Intel (R) 6 Series/C200 Chipset Family USB Host Controller with Driver up to date on both 1C2D & 1C26. The Microsoft fix for the NVidia Issue is not applicable to my PC,.

    It is a big issue and high time MS sorted it out

  • Hey Guys

    Sorry to blow out the link to N/Vidia in regard to this USB problem, I have EXACTLY the same issue but do not have N/Vidia on my PC my USB Controller is on the board and is an Intel Chipset.

    Intel(R) 6 Series/C200 Series Chipset Family USB Enhanced Host Controller - 1C2D & 1C26.

    I have a Dell Inspiron 620MT with a WD 2TB External USB 2.0 hard Drive.

    I initially thought bit was a failing hard drive as the drive also failed the DELL PC Tests when connected to my PC via the USB, I swopped the drive from one USB to another until IU had used all eight USB Ports, same problem on every ports.

    Tested the drive using WD Test Software PSSED OK

    Tested Again using Seagate Test Software Passed OK.

    Finally, downloaded the so called Microsoft FIX, it was a hoot, all it achieved was to completely trash my USB 2.0 and changed my Bluetooth to USB 3.0.

    Good job I backed up my whole system before doing that install, as I could not use my Wireless Keyboard & Mouse because my Bluetooth would not run the Radio Stick.

    Finally, like everyone else I live day to day by unplugging my USB Drive cable and then plug it on again that just proves the issue resides on the PC and not the Hard Drive.

    Any thoughts or advice welcome
