Seagate Laptop Thin Hard disk Recovery help

[bunty]

hello Friends
I have got a recovery job of Seagate 500GB laptop hard disk .
It has normal detection , I have made backup of firmware / rom as well in pc3k.
It has multiple firmware issues like smart fail / shock sensor warnings / weak heads etc.
While Head 0 is perfectly fine , head 1 is weak and data copying speed is extreme low - 0Kbps - 50Kbps (I am using PIO mode ,but higher speed does not improve data transfer speed)
What should be my ideal steps as most of the professional do ?
I dont want to do experimentation with client data so have not reset smart or tried anything else .
If someone could pls help with correct steps ,I will be grateful .

I would take out and examine heads, to be sure they are not damaging media. Most likely switch heads, my donor stock of yarra´s is "full"
Stabilize the drive by disable functions in sys93, image fs meta data and target imaging on mission critical data. Then image the rest of data.

Very good advice!

Hi Thank you digisupport
You have saved my day.

hi guys
I have done all as you have suggested (disabled functions in sys93) and reset smart ,but that has not improved response from one of the head .
For one head (0) speed is normal but for Head 1 is in few kb/sec.
Is this because of weak head 1 or some other firmware component is responsible

you need to get around the weak head by replacing it. That's the best you can do to improve cloning speed. However, if the speed is low due to bad sectors (surface problems) replacing the MHA may not give much better results.
There are ways of getting a better picture of what the real cause is, as well as making a weak head read again, but these are out of scope right now.
the simplest you can do is replacing the MHA and move on.

Thank you pepe sir
Yes you are right this has happened many times.Even after replacing healthy heads due to defective zones recovery has failed . You might be able to go and trace root cause on deeper level .
