The 9380E supports 1220 cylinders. The head/sector count looks right. I
have a 9380E formatted like that right now (though I'm using a Maxtor
4380E for my work disk until I get cables in for my expansion box).

I'm using 35 sectors, though, and the extra sector is for bad block mapping.
My current drive has no unmapped bad blocks as a result. You may well want
to go back...
