Partition: Write error

#1 Post by Nico87 » 07 Dec 2016, 21:20

Hello, I am trying to fix a lost partition issue on a Western Digital 4 TB, after an halt during a file copy from an USB external drive and a forced shutdown (as if one of the drive went to "sleep mode"). TestDisk can see the partition and I could save all files before trying to recover the partition (seen as RAW by Windows 7).
I have 2 exact same hard drive model in that computer.
  • UEFI BIOS displays the faulty disk as 3 TB while the sane disk is correctly listed as 4 TB
  • Windows Drive Manager displays the faulty disk as 4 TB as one big RAW partition
  • TestDisk sees the sane disk as 4000 GB / 3726 GiB CHS 486401 255 63 sector size = 512
  • TestDisk sees the faulty disk as 3000 GB / 2964 GiB CHS 364804 255 63 sector size = 512
I tried to changed the Geometry of the faulty disk to adjust it to the correct number of cylinders which is 486401 (not written on the drive itself unfortunately but I also checked the web and it appears that this number should be correct).

Then I went to Analyse, Quick Search, it found the partition fast (it was finding it even before the cylinders tweak) then I tried to "Write" the partition info... and this is were I am getting "Partition: Write error".

Here is the log :

Partition: Write error

TestDisk exited normally.
Does anybody have a clue on this ? Can I recover that partition ? If not, what should I do to make this hard drive usable again, as coming out from the factory or maybe is it damaged and shall I stop trying to fix it ?

Thank you

Check if the 3TB disk has jumpers that may be used to limit its capacity.
Please post the new log file using testdisk 7.1-WIP. This way, the disk model will be visible.
If it's really a 4TB disk detected as 3TB, you may have to remove a DCO and/or HPA zone using the manufacturer tools (or hdparm under Linux)
If you need a Linux LiveUSB, see https://www.cgsecurity.org/testdisk.pdf

The disk does not have a jumper to set a limit to the capacity.
Both disks are strictly identical, same manufacturer, model, size and the other does not have such jumper.
The disk was normally seen as 4TB before the USB file transfer issue and forced power shutdown.

Here is the TestDisk 7.1 Beta log :

I tried to rebuild the BS, but it fails, it throws me a Write Error again. My opinion on this is that TestDisk tries to write on sectors out of bounds that don't exist, due to the size issue. But even if I correct it with Geometry, it still doesn't work.

Some would say I have physical damage but I disagree, then why TestDisk would be able to list, read and copy all my files and Windows could not ? That is the maximum I can think on the topic, it's beyond my knowledge to repair it and I hope I will get some help here.

Thanks
