    Can't see external hard drive in Windows Explorer

    I am connecting an external hard drive (Acomdata 250G drive - pretty
    standard) via USB to my HP laptop running Vista. I am able to see the device
    listed under Disk Drives in the Device Manager. Drilling into Properties, I
    see that the device is running properly and, having re-loaded the device
    drivers, I have the most recent drivers.

    The issue: I am unable to see the device listed in Window Explorer, and thus
    I can't drill into the folders to get at the content.

    Any help is greatly appreciated.

    Is it assigned a drive letter in Drive Management?

    Right click Computer, choose Manage, expand Storage, and choose Disk
    Management.

    Many thanks, Colin. I had not found the Disk Management function previously.

    Unfortunately, the problem persists. The disk appears in Disk Management,
    its status is Online. However, when I right click the volume, the option to
    Change Drive Letter and Paths is grayed out. The only options are Delete
    Volume and Help (which doesn't have an answer for this issue).

    Here's a piece of information that could be the root of the issue: the data
    on the disk was written from a Mac. But it was written to be readable by
    both Macs and PCs.

    Any thoughts? Again, many thanks.

    Re: Can't see external hard drive in Windows Explorer

    The drive is probably formatted FAT32 since Macs cannot modify NTFS files.
    Vista should still be able to handle the files since Vista has no problem
    with FAT32. However I suspect that the drive was formatted with a Mac and
    Vista may not be able to mount it. Do you have another computer which you
    can hook it up to and see if you can pull any files you need off of it?
    What you need to do is get the files off, hook it back up to the Vista
    machine, use Drive Management to delete the partition, recreate the
    partition, and assign a drive letter. You shouldn't have any issue with it
    after that.

    Again, many thanks for the help. It may take a couple days to get access to
    a computer to follow the steps you provided, but I'll try it, and get back to
    you.

    I appreciate your expertise.
