I had 2 backup files, one made by Nero Backup Maker, and one made by ASCOMP Backup Maker. Both programs encountered an error while making a backup, and left a file behind which could not be deleted because the system said it was in use.
The firmware wa updated, and the drive rebooted. The files then could be deleted. As I recall, I had already tried rebooting the drive. Is there something in the software update which has solved this problem, or will I encounter this problem again if back up software encounters an error like the previous ones did?
