Hi,

Try to build a good copy of those based on the 2 copies.
After that try to write them back.
If drive can't write, use hotswap.

[guru]

Can you access data? And Does drive ID ?

[Scorpion]

I copied all the modules but the problem stay after rewriting tham again.
It seems like it didn't affect the drive at all.
I have access to the data. This drive has 4 heads.
I mannaged to save the data from 3 of those 4 heads but have problem from the last.
I checked the heads with PC3000 and it showed me that all of them are good.
I don't a donor for that drive. Is there any other way to solve that issue and get easy access to the data from the last head?


Regards,

You may find that those modules are protected and dynamic (restricted access by MCU FW) and therfore PC3k cannot read them. Quite typical of servo related code etc etc etc

Try read module by ID and you will see

[hddguy]

Looks like could be problem with checksum/header. Sure you can repair this within the utility. You tried this?

[mr_spokk]

Lot's of times WD utility says heads are fine when they are'nt.

That's right, sometimes this is the case.

You will need to change heads on this drive I suspect.
