ESI-32 Operation Manual
Formatting Hard Disks
This works exactly like formatting a floppy disk except when the display
asks you to "Select a Drive", you should select the hard disk instead of
the floppy. If the hard disk is not listed, use Disk Utilities 1, to Mount
Drive. The hard disk drive should now be listed. Formatting a hard drive
takes several minutes, depending on the size of the HD.
R/W Optical Disks
Read/Write Optical disks are formatted in the same way as a hard disk.
Use optical disk cartridges with 512 bytes/sector rather than the 1024
byte/sector type. New optical disk cartridges usually come with the "low
level" formatting already in place. If so, the disk will format normally. If
this low level formatting has not been performed, the ESI-32 will
interrupt the formatting process and show a "SCSI Hardware Error". If
this happens, follow the procedure for Low Level formatting on the next
page, then format the disk in the normal way.
Note: Optical disks always verify the data as it is written and so do not
require the long verify process that occurs after formatting has been
completed. You can save hours of time by ejecting the cartridge and re-
booting the system after the "VERIFYING FORMAT" message appears in
the ESI-32 display (about 10 seconds).
Hard Disk Interleave
The ESI-32 contains an internal list of recognized hard disk drives which
also contains parameter information designed to optimize the interface
between the ESI-32 and the drive. Most new hard disk drives use 1:1
interleave. The Appendix chapter of this manual contains a listing of
disk drives that have been tested with the ESI-32. Other types will
probably also work. If in doubt, the best idea is to try out the drive with
the ESI-32 before you buy it.
HD Interleave Options
There is a hidden menu when the display asks: "Are You Sure?".
Before choosing Yes or No you may choose one of the following hard
disk interleave options using the numeric keypad:
0 --- Uses the ESI-32's default interleave for the type of HD.
Fast 1 --- 1:1 interleave
2 --- 2:1 interleave (this is the ESI-32's default setting)
3 --- 3:1 interleave
4 --- 4:1 interleave
5 --- 5:1 interleave
6 --- 6:1 interleave
Slow 7 --- 7:1 interleave
8 --- Install File System
9 --- Optical Disk Low Level Formatting
Option #8 allows you to install the ESI-32 file system on a pre-format-
ted hard disk. This option is quite handy since it saves the time of
formatting. Many hard disk drive brands of now come pre-formatted.
