My media PC's hard drive (750GB Samsung Spinpoint), has developed some bad blocks, I suspect from a power cut we had a couple of weeks back. I know they are there and have a copy (paid for) of HDD Restorer, an excellent app which actually repairs them. The problem is that unless you know where they are the program has to do a full surface test. You can tell it to start at a certain point, but there is no point in that unless you know where the bad blocks are located. I left it running over night and it had only managed 80GB with none found. Does anyone know of a utility which will report on the location of bad blocks so I can repair it in minutes instead of days?
