    problem ejecting USB mass storage drive


    This is really mysterious. I have an external 2.5" USB drive and for
    god's sake I cannot safely remove it from my Vista ultimate 64bit
    system! :) I copied something on it and I am quite sure, that safely
    remove is good to do, because I use such drives for some time already
    and I already lost some files when it was not done (my computer froze
    something)! Process explorer shows nothing when I search for my drive
    letter. I tried some unlocker utility, but it does not make it's context
    menu...maybe after restart it will :-\ I disabled indexing for fast
    search on this drive, but nothing changed...Maybe system restore?...

    You might try this to see if anything else has grabbed a hold of it.

    System restore it no more a problem under Vista.

    The ProcessExplorer often cannot resolve drive letters, you have
    to search for the drive's 'DOS device name'. My drive removal tool
    shows it:

    But even the ProcessExplorer doen't seen all handles. For
    instance the handle to container file mounted by TrueCrypt
    isn't seen.

    C:\programy\utils\removedrive>RemoveDrive.exe g:

    RemoveDrive V1.8 - prepares drives for safe removal
    Freeware by Uwe Sieber - 'Uwe Sieber's Homepage'
    (http://www.uwe-sieber.de)
    Removing Drive 'G:\' (FUJITSU MHT2080AH USB Device)..........
    check for open handles on volume 'G:\' or '\Device\HarddiskVolume5'
    failed



    So what does this mean?

    Same as "The device xxx cannot be stopped right now." when
    using Safely Remove Hardware facility.

    Search for "Volume5" in the ProcessExplorer.

    I tried it again - procesxp found the explorer.exe holding it, because I
    forgot one window, but when I closed it and tried removing drive the
    normal way via tray icon it seemed like it is working but after a little
    longer time then before it again said that it cannot be done. After I
    tried the removedrive utility I was not able to find anything again with
    process explorer... Anyway I think that the data has been flushed to
    drive even that windows says it could not be removed...

    check this: 'UKAZTO.COM'

    VistaLoWang, take a breath. I don't think I got all that.

    I have the same problem with you - but I am running on Vista Business
    32bit. (It is a Toshiba 160GB external USB mini-hard drive device).

    When I try 'Safely remove device' I get the message 'device still in use
    - cannot eject'

    Sometimes - but only sometimes - I get the 'OK to remove the device' if
    I just close the Explorer.exe completely.

    This isn't a "problem" rather a lame Microsoft feature. You'll always
    get a "can't remove" error if Explorer is open IN THE DRIVE you're
    trying to unmount or if any application is using that drive.

    Another day I could not safely remove my USB hard drive, so I ran
    Process Explorer as admin and look what held it!

    (http://www.ukazto.com/?img=2937464~removedrive1.jpg)WTH can I do with
    this? :o It did not seem like it is going to release my disk ever...

    Surprisingly next day I was able to safely remove my drive...
