Yes, it’s an old drive. It will still boot Win XP fine, but fails DLG Quick Test and extended test. Acronis hangs at 2/3 complete on the clone process, and Extended DLG test fails at the same sector every time. Trying to clone this (my C drive) to a new one before it fails completely. Tried searching the forums, but nothing specific to this problem. How can I mark the sector bad to get the cloning process to complete?
