- As long as the ZIP drive has fewer than 196589 blocks per disk this will work
- fine. The precise numbers matter only in so far as you must not attempt to
- access anything beyond the last block on the disk. SCSI does not speak heads,
- sectors, blocks per track, cylinders or any of that stuff. That is hidden from
- the SCSI interface by the higher level SCSI logic which looks at the disk as a
- long string of blocks.
-
- If you have several disks you DO want to have them all formatted the same. This
- will facilitate the disk swapping situation. If you have several machines and
- wish to share disks between them then making them ALL the same parameters will
- facilitate things tremendously. (In terms of "all the same parameters" the total
- number of blocks used in mountlists etc is all that is critical. This means that
- the actual starting block number and ending block number are all that really
- matter. With your configuration you might have "lowcyl = 1", which means the
- starting block number is 68, and high cyl 2890, which means the last block used
- is 196588. You could have these same numbers with say 17 blockspertrack and 4
- heads, which multiplies to 68 blocks per cylinder. They'd "diskchange" just
- fine. Thus there is no one precisely "right" set of parameters.)

- The new stuff is intelligent enough to know that only people smart enough to
- REALLY know what they are doing should even attempt to low level format a hard
- disk. Or so it would seem. "Don't do that." Partition the drive and use high
- level AmigaDOS formatting. (I know of no low level formatting software for the
- Amiga that I implicitly trust.)
