-
- The MountList file, and any DOSDrivers files you have, are simple
- descriptions of various AmigaDOS level devices. The DOSDrivers files
- are processed automatically by your startup-sequence, while the
- mountlist entries are entered manually (on a CLI) or in your
- user-startup file.
-
- A DOS device needs a name (eg, "DF2"), an Exec device and/or DOS
- handler (eg, "trackdisk.device", "L:FastFileSystem", etc), and usually
- some device-specific information. For a disk drive, you specify the
- drive's geometry: the size of a block, the number of blocks in a
- cylinder, the first and last cylinder, and the number of heads. The
- total number of blocks is all that matters in most cases, since the
- Exec-style device drivers are logically addressed, and hide this
- geometry from you. But since manufacturers supply it, that's the
- simplest form in which to define what a disk drive looks like to your
- system.

-
- No idea, I don't know diddly about ZIP drives, beyond "it's a fairly
- cool 100MB floppy disc". What does your ZIP drive's documentation say
- about this? Or how about the ZIP drive itself? Most SCSI drives will
- report their size, HDToolBox (among others) can inquire of the
- size. If the ZIP drive doesn't handle this, contact IOmega. Also, you
- might want to check out the various mountlists in greater detail. The
- total number of blocks is all that really matters. If you have
- different settings that add up to the same total, use either one. If
- they add up differently, get the manufacturer's recommended geometry.

-
- Not really. Some SCSI devices are smart enough to know if the media
- they support needs low-level formatting. Maybe the ZIP won't do it if
- the disk you give it is already cool.

- No.
