Hello,
I have big problem with Seagate ST9500325AS hard drive. Yesterday I was not be able to boot up Windows and then I tried to rescue data.

The drive is normally detected by BIOS, Linux distros (like SystemRescueCd, Parted Magic) and MHDD.

MHDD can show ID (F2) and EID (Shift+F2)

Code:

ST9500325AS   LBA: 976,711,055   BIOS: 81H
SN: 5VEJEK6Z   FW: 0006SDM2      CACHE: 8192 KB
Size = 476938 MB

smartctl on Linux and MHDD can read SMART attributes (F8) - see below

Code:

MHDD can read LBA from 0 to ~6280000 without delays and then I get x UNC (badsector). After this I can see only ! ABRT. Drive is not accessible anymore. To get access again the drive has to be power cycled.

After this I started scan from LBA 6300000 and again I get x UNC (badsector) before ~32100000. Next scan I started at 32100000 and it the same thing as before.

When I tried to make 1:1 copy by ddrescue to another good HDD.

Can anyone help with this?

English isn’t my native language, so please excuse any mistakes.

Hi. The drive is unstable of course.
Have you tried doing a reverse clone? So that would be starting at the last sector and finishing at sector zero.

You need hardware cloning tool to rescue data (PC3000 DE, MRT DE, Deepspar, etc).
If you can not afford these expensive tools, then you should contact someone who has them and that can clone the drive for you.
Professional DR have those tools.

Those HW tools can skip bad sectors and continue cloning surface by using many techniques (fast jumping, low reading timings, inverse cloning, software and hardware reset, head recalibration, automatic repower drive on reading error, etc).
Those tools are also able to do sectors and head map, so you'll know what area was jumped, this way you can try to clone those skipped areaa in a second pass.
You also can find which data got damaged and which got copied correctly.

If you value your data, seek a data recovery professional now, and quit messing with the drive. The more attempts you make, the more damage can be done.

If, however, the data is not valuable to you, and you are not willing pay for recovery and willing to accept total data loss, there is another program you can try instead of ddrescue. The drive appears to be going into a fault state when it reads certain parts, and once in fault it will not read again until power cycled. Ddrescue has no way to detect this condition, all it knows it there was an IO error that it considers a bad read. But HDDSuperClone can detect this, and it will stop with a message at which time you would need to power cycle the drive and start the program again. But this is only if you don't value your data, and are not willing to pay to get it back. You would be taking a big chance. The drive may be damaged in a way that you have no chance of a good recovery on your own, and the potential to destroy any chances of a professional recovery.

Try disabling various features via the drive's serial terminal interface:
