ST4000LM024-2AN17V - No data Access

[odedshankar]

Hi Guys,

I've got a ST4000LM024-2AN17V drive that came in with bad heads but no obvious media damage.
I swapped the Heads successfully and the drive started very slow and not completely but i managed to get to the terminal after a while and created backup of the SA. at this stage still not id. I executed the U10 command and still no proper id., i modified mod pages and unticked all items other than Media Cache but result still the same, and then checked V40 command to check NGLIST and it was empty, so executed the m,6,3 cmd which executed properly and after restart, the drive id's good and i can enter the utility properly, but still no access to the data area, i am getting ABR err every time i'm trying to access a data sector. Reading data though disk utility works, so most likely its a firmware issue.
Did you experience a similar case? where do you think the corruption is?
I attached the current startup log from the terminal.
I am assuming it relates to the following error:
SP213: Restore: EXCEPTION: Scratch Pad Restore Failed, the MS may contain errors

Thanks Guys

Just an update, when i try to read the MCMT sys files they are good.
But when i try to read the 0028 Sys file from Volume 2 it crushes and i get Led error - so i believe possibly that may be related to the problem.
I saved Sys file 0028 from Volume 3 both copy 0 & 1 without a problem, so not sure if Volume 2 Sys 0028 may have any meaning but every time i try to read or writ to it the drive crushes with LED ERROR.

Any idea if it may causing the issue, or something else that you can think off?

I am still trying to investigate where the problem may be?
I tried to read all the Modules, most of them successfully, but there is a group of modules with description of "BIG FILE" from index 44-4A amd most of them i can't read only 45. Does anyone know what are those files?

Checked a good donor drive and its the same, reading Volume 2 sysfile 28 crush the drive and it can't read as well all the big files, so can eliminate that.
