But it's no different than any other read or write. So whenever you'd try to erase all the blocks, the original block would stay unchanged, and the reallocated sector would be the one that's cleared. The entire purpose of Secure Erase was to ensure that EVERY single sector on the drive is 0'd out, even if it's been relocated to the bad block list.

Once your PC system cannot finish the CRC on your PC or hard disk, it often will repeatedly copy and paste data to your drive and makes your desired hard disk operations impossible. After a certain number of retries set by the manufacturer, the drive will mark the sector as bad, and any future data will be stored in the reallocated sector block. As far as I know, the only ways it could do that would be to disable Error checking on the drive and have the program run it itself, or to clear the bad block list of that block after it gets reallocated.
It's a proactive measure to find troublesome spots by writing garbage to them and seeing if they can retain it. Try these options to resolve CRC Error: 1.Error Checking Tool under Disk Properties of Tools Tab. What program do you use to do the surface test? As long as ECC is enabled, whenever the drive attempts to read a sector, it will check the data against the ECC, and if there's a conflict, attempt to read it again.
