    Seagate External Drive Issue

    I recently had to do a complete reinstall of Windows 7 on my personal laptop. Prior to the rebuild, I had used an external hard drive from Seagate to backup my personal files. When I connected the external drive via USB to my newly rebuilt laptop, Windows 7 advised that it recognized the drive and loaded the appropriate driver software.

    However, when I opened Windows Explorer, and expanded My Computer, it only showed my local hard drive and the CD/DVD drive. When I opened Devices and Printers from the Start menu, it showed that the Seagate external drive was installed. I tried to connect it to my wife's laptop and experienced the same results. I also tried using a different USB cable to the external drive with no luck.

    I next went to the Seagate web site and found a troubleshooting wizard that I followed. It even went so far as to have me open Device Manager (where I could see the external drive) and use Device Manager to ensure that Windows was communicating to the drive. All troubleshooting wizard steps were completed successfully, but I still cannot actually use the drive or its contents through Windows.

    Is my external drive done for? Thanks for any help you might be able to provide.

    Many people have posted that they have booted their computer with Linux, and that they have then successfully mounted the drive that wouldn't mount in Windows. They were then able to copy the files to the internal hard drive.

    When I get some time, I have a few drives that I need to try that with.

    Another alternative, which you might not want to do, is to open the case of your external hard drive, and remove the hard drive inside, and then mount that drive as an internal drive in your computer. That sometimes works, but not always. But it will likely void the warranty on your external hard drive.

    Hi cjdahl60 - What does the Seagate external drive look like in Disk Management?

    (In Win 7, click Start then, in the Search programs and files dialog, type diskmgmt.msc then press the Enter key.)

    - Does the Seagate external drive show up?
    - What's its status (shown in the Status column)?
    - In particular, does its Status show it as Healthy?
    - Does it have a drive letter?
    - What File System is it using (FAT32, NTFS, etc.)
    - What happens if you right-click on it and choose Open or Explore?

    Hello, cjdahl60.

    I have two Seagate Flex drives and they both show up as expected. This does not help you. You can go to your HD in a Windows ( GUI ) way : Control Panel -> Administrative Tools -> Computer Management -> Disk Management, voilà ! Get to this window and see if you can Open the HD there. Get back to us. Jean.

    Typically, drivers located on an external drive should be installed manually, and not by allowing Windows to look for them automatically.
    I'm also a bit concerned by your wording; external drives do not typically get installed, they are plug and play and are therefore "recognized".

    One of the simpler things that should be tried; the drive should be disconnected and powered off completely for a few minutes.
    Reboot your system and then try connecting the drive again.

    You might also try killing the explorer.exe process from taskmanager, then re-enabling it.

    You could also try getting the drive recognized in Windows via safemode, if this works, it might tend to
    suggest that some Windows process has taken some degree of control of the drive rendering it usable from a read-mode perspective,
    more exclusively than a write/viewable mode. (I might be reaching with this one too)

    Thanks to all for your suggestions. I received email notification of the first reply, but not to the ensuing replies, so I'm late in reading these. Give me a day or so to run through these suggestions and I'll post my results.

    Again, thanks everyone.

    I wonder if Windows might have scrambled the DUID for this drive:

    Here's a couple of screen captures of what I see with the external drive connected via USB and with Device Manager and Disk MgrDevices.PNGdiskmgmt screenshot.PNG

    cjdahl60,

    The Disk Management screenshot shows your Seagate external drive with no drive letter or file system.

    I'm aware that Seagate issued a firmware fix for certain Barracuda 500Gb models which had the same or similar symptoms, i.e. data becoming inaccessible after a power-off/on operation.

    Have a look at this Seagate page for more info and for their USBDriveList software which should identify the model/serial no. of the hard disk inside your external enclosure without you having to dismantle it.

    On the same page you will be able to use the serial number check utility to check whether there is a firmware fix available for download for your particular drive using Seagate's Download Finder:

    In disk management, you should be able to right click on drive 1 and assign a disk letter to it and allow you to see the drive in Windows Explorer.

    Rick: The first two links provided come up as page not found in my browser. I was able to use the Seagate Download Finder link and the result showed that there were no new firmware updates available for my drive. I downloaded the Seagate Tools for Windows utility found on the same page and ran the available diagnostic tests, all of which were passed successfully.

    jwitalka: When I right click on the drive in disk management, all options are grayed out except "delete volume" and "help." I'm not sure if I should delete the volume and then try to have Windows recognize it as a new device again.

    All:

    Problem is now resolved. I deleted the volume using disk management. When I plugged the external back into the USB, Windows recognized it and allowed me to name it, assign a drive letter and format it for initial use. I had once plugged this drive in a Linux computer and it appears that this did something to the formatting or contents that Windows didn't like.

    I was using this drive as a redundant backup to a primary backup, so even though I had to reformat the drive all is well. Thanks again to everyone for your advice and direction.
