It's a bit more complicated than that. There's a geometry table at the
start of the drive (that's why you don't have to tell your VAX what "drive
type" you have) and a bad block table at the end.
As far as interleave goes, it's not _really_ critical; a drive will work at
any interleave, it'll just be slower at some interleaves than at others.
I.e., if interleave were the only problem, you could format a drive and
have it useable even without knowing the proper interleave for the VAX.
