I have this model of hard disk and when I copy sectors it does it on the 3 - 40 MB / S, but after a while it starts to give BUSY, and this message in the terminal:

The 2 lower heads are fully bent and I have replaced them. Remove the disc plates to examine the lower plate and it seems to have no damage, in fact it reads the SA but with errors.

I had to replace the heads and cleaned the top plate.
The HDD finds bad sectors when reading the SA, specifically in the Alist.

I have some doubts:

The head 0 is the inferior?
Can it be removed and how is the atomic reassignment of sectors?
The upper plate was whitish, do you recommend removing all the dishes and cleaning them one by one or do I first read everything I can?

The heads 0 and 1 are the lower ones and have damage caused by the heads removed. Heads 2 and 3 read them well.
I have the problem with the ALIST that when reading, it finds bad sectors, it enters BUSY when trying to read the ALIST.
With PC-3000 the problem is relatively solvable reading through the UTILITY.
With MRTLAB, what I have is not supported. I'm going to see if modifying the FIT module I can relocate the ALIST and I'll comment if I get it or do something else.

I do not see the option.
I'm going to ask the technical service of MRTLAB and comment.
At the moment it is copying the HDD but very slow, if I leave it for a long time it comes out of the BUSY state.
He gives me reading errors but when he tries again he reads them. We'll see.

By the way, to clean HDD plates one by one, is there some kind of support in the market?
