This is a mount scripts collection for ZIP drives.

Features:

* More compatible FFS sctructure with all programs using it. (DiskSalv,
  QuarterBack Tools, Reorg, etc...)

* More available free space in AFS format.

* More compatible and fast formatable MAC & PC ZIP disks.

Why another mount scripts collection for ZIP drive? Well, I actually have a
ZIP drive, and all mount scripts I've seen don't work properly.

The mount script from HiSoft for Amiga using FFS, have a correct number of
sectors defined but some programs thinks that the number of sectors are
greater than the real number of sectors, there aren't reserved blocks, and
for this reason, there are problems with disk checking or optimization
programs.

HDToolBox from OS 3.0+ recognices a ZIP disk like a hard disk with 2891
cylinders, 68 sectors per block and 1 surface, this definitions are wrong,
a ZIP disk have a total of 196608 sectors and with this configuration we
have 68 * 2891 = 196588 sectors (a little less). ZIPMount_12.lha and
ZipAFS.lha both from Aminet have the same definitions reported by HDToolBox,
with ZipAFS there isn't big problems, but with ZIPMount we can't access to
all possible information in a ZIP disk in MAC or PC format.

Other mount scripts I have found for MAC or PC ZIP disks have definitions
like 196608 cylinders with only a sector on each one, this will work without
any problems but if you want to format a ZIP disk in MAC or PC format, this
will take about 2 hours to complete.

Installation:

Copy the icons to your "SYS:Storage/DOSDrivers" folder, or to
"DEVS:DOSDrivers" if you want the drive to automount, and modify the icon
tooltype "DEVICE=YOURscsi.device" to show the name of your real scsi device
name.

Definitions of the mount scripts:

ZIP disk = 196608 sectors

196608 sectors / 2 sides = 98304 sector by side.

98304 sectors by side / 64 blocks per track = 1536 cylinders

Why 64 blocks per track? Well this is because the greater number factor of 2
to divide 98304 is 64.

Why the lowest possible number of cylinders? (1536) This is because the
format command is faster with less cylinders.

Known bugs:

I can't format a ZIP disk in PC format using CrossDosFileSystem with any
PC mount script. Is this a problem of CrossDos? If you can format a ZIP
disk in PC format, please e-mail me.

P.D: I want a standard format for Amiga ZIP disks.
