Hi to all, I recently purchased an external 80 GB USB 2.0 disk drive to attach to my notebook under Windows XP Pro. I had no problem to have it recognized by XP and partition it, although only FAT32 partitioning works successfully. The drive has no power on/off switch and is powered by an external adapter which I simply can plug or unplug. The problem is that the disk will work correctly as long as I do not power it off (even when the notebook has been shutdown). In that case, it will no longer be recognized by XP unless I unplug / plug the adapter cord, and then all partitions will be absolutely ruined... I tried converting partitions from FAT32 to NTFS, but it does not bring any improvement. This makes me crazy ! I could find no solution so far. Any help would be most welcome.
