I have a Maxtor One Touch external HD. I was using a piece of video editing software to edit a file located on the external HD, when the software crashed. The PC had to be rebooted.
Thereafter, the drive letter for the Maxtor was different. If I try to access the drive, I get a message telling me that the "directory or file is corrupt". I guess the fact that the editing software had an 'open' connection with the HD had corrupted something.
I can't re-assign the previous drive letter, because it's no longer available to select.
There is hours and hours of work on this drive, and I'm desparate not to lose it. I have contacted Maxtor with my problem (I'm waiting for a reply), and trawled through their knowledge base.
