Hi miki

I tested it already by HD doctor for WD

All FW modules are ok.

thanks for advice

If u get IDNF errors anywhere while scanning then and then u rescan the drive it doesnt show up then check ur pcb if not then could be a translator issue .

hi rameez

thanks you for answer

If the problem is a translator issue what should i do ?

I already checked all firmware modules and they are all ok

thank you

If all modules are ok, so u could be get some weak head, tried to check on wich heads show the UNC errors

Best Regards

Hi,

If the drive shows some UNC sectors, this can be media problem also.
If one of the heads is weak, this comes everywhere on the area in good and bad bigblocks.

If the drive has only 4 UNC sectors, and after this the sectors are good, i guess this is only media problem.

Regenerate translator and do a full erase to repair the drive .

thanks rameez

but how can I regenerate translator using hd doctor for Wd ?


thank you
