Hello Guru's,

I could use a hint or two. I am dealing with a 7200.10 and suspect small scratch in SA.
I would like to format SA and then reload firmware tracks. Instead of formating the entire SA, I would like to just format the tracks affected by the scratch. Can someone provide me with the correct Format Track command syntax in Level 2?

Fxxxx ???

Thanks for your help!

If you need the drive and not data why not selfscan? In DR case, did you check the depth of surface damage, if present?

Thanks for the response BlackST.

I do need the Data, so Selfscan is not an option. Surface damage appears to be only on a few tracks. I did not physically inspect platters. Problem occurs when trying to write cert tab module with SD and or try to write to these tracks individually. I can read the tracks with no problem. Heads tested fine too; therefore I think that it's a small scratch. I know how to format entire SA, but I would rather not.

Thanks

Hi
You should first seek to that particular track and after that use F,E in level 2 (2/>F,E) ....

A doubt : will it work to format a track when track physically damaged ? And what happens in that case ? (I never had the need for this, selfscan do a relocation if necessary by itself... but don't know what's behind the mechanism)

BlackST,
You say you never had the need for this, then do you have an alternative?

I will let you guys know what happens...

Never had the need = luckily no scratches or potential scratches on SA yet. This case gives me the possibility to think about an alternative .

Do you really want to be deliberately interacting with the physically damaged area on the drive? Thinking of possible head damage as a result...
