I think it is because it is designed so. They could have do it by shingles as well probably.
BTW, i think it is done by zones on rosewood, they have more zones therfore they are less wide.

I think it has something like 3,3GB on each head so it's definitely worth recovering.

definitely, but the amount is not constant, varies within a pretty large interval

I have done many, many Rosewoods with media damage on one surface by snipping the culprit head. Of course there’s more to it than just the “snip” :-)

H1 and H2 on 2Tb ones are a little awkward so they could be bent as Pepe says, but I prefer to snip.

Good to know :-)

Like 50% from a single platter 1Tb rosewood in a “toughened” LaCie drive, including (luckily) 75% of the photo shoot the client was after! Top surface was scrubbed clean :-(

Do you edit the adaptives to reduce the head count? I suppose you also edit the head map?

That’s right

I wonder if different FW versions of Rosewoods act differently.
