Where possible, we recommend connecting the hard drive to another computers to see whether it is able to be detected and initialized. If it's a brand new drive with bad sectors, I'd RMA it immediately. Now we're disagreeing with how secure erase affects the bad block list, so let's ignore that for a second.
It's a read-only test and it aborts the test as soon as it hits a broken sector, reporting the LBA-address it aborted in the selftest-log. Since the drive is not accessible or cannot be initialized right now, you can recover data with FonePaw Data Recovery.FonePaw Data Recovery, aiming to restore data lost logically, is a data recovery tool which supports the retrieve of photos, videos, … Since surface-test doesn't cause a reallocation, I don't see what else it would be that's causing it other than the secure erase. Step 3: The deleted volumes will be listed in the window. needsomeaim But getting back to the secure erase, my main question for you is, are you checking the smart logs immediately after the secure erase, before you attempt to access any data, or run any surface test, or are you doing something else first? No, it very definitely doesn't. (I often do this process to recover older disks). 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.
