Strange behaviour of SP8004H

[dobrevjetser]

Hi Friends,

Strange case with a samsung SP8004H
The drive came in with the SA badly damaged. Using composite reading, i could read all modules.
Writing the SA was not possible.
So i got an identical drive and made a hotswap.
I used DE to make a data-copy.

Strange thing is: All sectors that are read as good are empty, and the sectors read without CRC control contain valid data

I changed heads and could rewrite the SA modules, some are still damaged but not the critical ones. Still same problem. No data

I also tried to read the entire disk without CRC, but that is not giving good result.

Anybody a suggestion?

Thanks in advance,

Dobre

Hi Alberto,

Most errors are UNC but sometimes it is also AMN.
