If there is still doubt in your mind, then I recommend going to the websites of the various hard disk manufacturers.
Correct! Logic tells you that if there is a problem with the MFT or any FAT-related problems - a defrag may not even be ABLE to run to completion.
I met Steve Gibson years ago and while he may seem a little alarmist, he really knows what he is talking about. Spinrite is an excellent program and well worth the money.
As to which defragger to use - I have found Ultimate Defrag to be without peer. Best display of fragmentation status ever.
