I had same problem.

And I have an solution for you... The problem is that when you plug in your HD first time, Windows 7 install your HD and associate it to only this USB port (let it be USB port "4") than if you wanna to use it (HD) again, you need to plug it, in the same USB port (USB port "4") where it was installed first time. It is Stupid!!!! But that's how it worked with my HD.

Just try all USB ports that you have on your PC.

Good luck.

Hope it was helpful. :D

PS: the same problem is with all divices you plug in to your pc.

    I too have this problem with an ext HD that is SATA via USB. Brand new drive.

    I can see the files that I placed on it after format (Win 7 disk manager). The drive seems to work fine, however, SyncToy and FolderCloner will not sync my backup files to it (it is a second, redundant backup). Once I launch the sync in either program, I see cycling "must format this drive..." and "Autoplay" selection menus, repeatedly, until the sync programs say they cannot accomplish the sync. I have not seen this previously (with the prior drive that died), and the problem is NOT corrected by changing the USB port.

    This is a major problem, and we need an official MS solution, please.

    I have precisely the same problem

    This clearly is a Win 7 problem!!! Not a drive problem...

    MS - please address this. It may cause ignorant people to format their back-drive...

    CheckDisk : chkdsk e: f/

    The correct syntax is

    chkdsk E: /f

    assuming that your drive is E: - change this to the drive letter that is valid for you

    To run this command you should open the Run command in the Start menu.
