I have HDD model ST9500325AS. The HDD is detecting. I have done head mapping. The image from Head 0,2 & 3 is fast and perfect. But while reading head 1, it is extremely slow. what should be done.

Guess that you should wait for the clone to finish even if it takes lot of time.
If waiting is not an option or if head ends up dying in the process you have to replace the head stack inside a hepa 100 asseptic room or outsource to someone who can do clean room work.

if all lba on head 1 is slow then you can set udma33 and 100% head 1 is weak
