    I have Windows 7 installed on a PC, and try to attach a external 2.5" Seagate 320GB harddisk. The PC itself is perfectly able to see this disk, and even boot from it on startup. There is onyl one partition on this disk, type NTFS, and it can be quickly found on any other PC in Windows.

    When I boot into Windows 7 on this PC, and attach this external hard drive (remember, it's not a hardware problem, this PC is even able to boot from this disk!), it is quickly recognized by Windows, but the partition type is unknown, Windows only detects one partition that has no type or name, nor a drive letter in the Disk Management console.

    The problem is persistent, tried many reboots, shudowns, but the problem persists. Please advise me what to do next.

    TIA

    Have you tried giving the drive a drive letter in disk management? Also look in device manager and see if there are any unknown devices in storage managers (usually under universal serial bus controllers). If there is then delete it and rescan for hardware changes under the action tab and see if that solves the problem.

    Hi,

    Also, maybe you could try reinstalling USB controller drivers for a test.

    Hi,

    the solution was not to appl a driveletter, which makes no sense since no filesystem was recognized. But instead, I uninstalled the disk in device manager, reattached the device to my computer, and suddenly it was correctly recognized by Windows. Really a strange bug...
