I am by no means a expert on this but I'll try to provide some info, which others may correct. ;-) I had a situation similar to yours a few months ago. I had a bad spot that popped up. After some effort, I got the drive to mark that as bad. Now, from my understanding, the drive sort of has some extra space that it can use if needed. However, at some point it will run out if you have spots going bad one after another. Again, my understanding. Let's say it has 200 extra spots. You then run the test or the drive detects on its own and finds a bad spot. It marks that spot as bad and then uses one of the extra spots. So, if you have 201 spots to go bad, you fresh out of luck. Again, that's my understanding of this. Now can someone else that knows even more than me explain this better? :-D Dale :-) :-)
