Translator fault after head swap - ST1000LM024

Postby avalanche » 21.07.15, 11:08

ST1000LM024 in with head failure. Heads were replaced successfully and HDD enters RDY.

Quite a number of firmware modules were unreadable reporting UNC or ABR on all heads. However increasing the read attempts in utility from the default of 102 to maximum of 255 allowed reading of nearly all modules. There were particular problems reading S-List to begin with

It is possible to read sectors, however there appears to be a translator issue - data in sector 0 is wrong, and other data the disk reads does not correspond to what would be expected in that sector. Reading parts of the MFT allow access to file entries, but opening the files they nearly all have the incorrect header. RAW recovery provides good files.

Perhaps one of the defect lists is not correctly being loaded? (S-List)

Terminal output below from power on.

Thanks,
A
