I got a momentus 5400.6 (ST9500325AS , Firmware - 0011) from Home customer

I connected it to pc3000 udma & have firstly taken firmware backup. Disk was having normal DRD DSC and detection.
I have even copied MFT's and given data details to customer.
Suddenly while trying to make image of mapped folders , drive become busy & now it is deected as 0MB. It has also started giving LED error.
Terminal output is as following -
Is this translator violation or head related issue , can someone pls. throw light .

Thank you fzabkar

Servo error means serious issue , I will have to inform customer as recovery will be complex and costly .

So that I as a newbie can learn from your expertise -- what exactly happened - servo error?

We can do head replacement only , we cant do anything else. May be new head if in good condition will be able to give sector access
