Do you happen to know at which LBA sector it starts to fail in DBAN?

Current pending sectors aren't always bad sectors. Is the reallocation count low? The only way to force reallocation is by bypassing the write cache/buffer and use direct I/O

in 95% is failure,, start for 875,000,000 LBA until 975,000,000 LBA is BAD on mhdd, 4 pending sectors

force write cache/buffer on 82 00 00 00 00 00 EF ?

Try the following on Linux:
Code:
su

dd if=/dev/sda of=/dev/null skip=875000000 count=1 iflag=direct

If it returns something like this:
Code:
dd: error reading ‘/dev/sda’: Input/output error

Then try this to force the reallocation:
Code:
dd if=/dev/zero of=/dev/sda oflag=direct seek=875000000 count=1

And redo the first command to check if the sector is readable again. If it's not, the hard drive is probably badly damaged

You would need to do it like this instead:
Code:
dd if=/dev/zero of=/dev/sda oflag=direct seek=875000000 count=65000000

Then you're out of luck. How many sectors were remapped on this drive?

hello, im new in this forum and i was curious about this topic… well, i had an old conserved drive here with 80 gb of storage and decided to give a try on this… my drive also bricked after using phoenix. bios takes 10 seconds to recognize drives but ends up not recognizing this one anymore… i also thought the guy was saying bs but i have to confirm it does bricks drives since it bricked mine… i will later try to use a magnet to check if the drives gets alive again…

If it was a capacitor problem, the drive wasn't even supposed to power on

Try to use shred instead:
Code:
shred -vzn 0 /dev/sda

So, I ended up putting the drive in the freezer four times or so, that didn't solve the issue. But then I thought about using a magnet and it worked! I have no idea why but after magnetizing the drive there are no more read failures. Though, I still think there is something botched in the drive's firmware, S.M.A.R.T. data's attributes got randomized a couple of times after freezing the drive. This is not new though, it used to get randomized very few times even before I froze the drive. But stopped after using a magnet


You freeze the body and the pcb together?
and how you do with using a piece of magnet?

1 - It's impossible for a OS to brick the drive. In worst case you would need something like a malware/virus that would gain kernel access to send direct I/O to the drive and use VSCs to kill the firmware, etc .... Meaning ... There is NO WAY for the OS itself to "damage" the drive even more in the way you describe (progressive damage over time with changed S.M.A.R.T. data).

2 - If you put a magnet on the top of the drive if you are lucky not to damage the heads you will end up damaging the platter anyway. Servo marks will be gone, heads will not find servo and drive will just click ..... The freezer and other junk that you did write will only make matter worse.

I will not comment any further just if someone is thinking of doing something like this to refurb or ressurect a drive just forget, IT WILL NOT WORK. EVER.

This is BS.


hmm it no good


Quote:
Why you say it's bullshit? I literally put the magnet (which wasn't powerful at all like those in a microwave) around the drive for 3 or 4 times (I haven't disassembled it), without exceptions. That was the only thing which 'ressurected' the drive.
