SSHD ST500LM000 KO

September 26th, 2016, 4:09

Hi, first, thank you for the great forum.

I have patient hdd:
ST500LM000, PN: 1EJ162-286, FW: AS12, NAND: Samsung K9LCGY8S1B-HCK0

And the donor hdd:
ST500LM000, PN: 1EJ162-038, FW: DEM9, NAND: Toshiba TH58TEG6DCJBA4C
ST1000LM014, PN: 1EJ164-040, FW: DEMD, NAND: Toshiba TH58TEG6DCJBA4C



As I think (and read on the forum), that there is wrong the NAND flash. On the serial console I can see:
ERROR: Flash Led 9C17 - RestoreALFTablesToDRAM Failed - could not recover data from Tables Clump

Clump Parametrics:
Clump = 0191

Ant that's all. No F3 console. Changing of the PCB did not help.

Is there any way:
a) how to download all firmwares from the patient PCB, and restore it to the donor PCB?
b) is possibility with some short circuit or something how to ignore this "RestoreALFTablesToDRAM" check and spin-up the disk?
c) is really the NAND flash dad, If i buy the same NAND and change it on the PCB, it will help? Or is something important saved on this NAND chip?
d) is any way, how to restore the data from the patient disk in my home environment?

Thank you, for any answers and helps.

A) I am using pc3000 to do it.
b) no
c) no. it is media cash in nand.
d) no. unless you will buy something like pc3000. It should have support for this problem soon.
