Appendix C: Mass Storage Options

Triton Elics recommends you use HP media cartridges because they are very

reliable and have a 30-year warranty.

Media cartridges with 512-byte sectors written by other compatible magneto-optical

drives (for example, Sony and other ISO-standard drives) can also be read by the HP

multi-function drives.

C.4.3 High-Level Formatting Considerations

In general, you need one hard disk partition per side of the M-O. You accomplish this

using AFDISK. In addition to knowing the low-level format of an M-O cartridge, such as

the number of bytes (typical 512 or 1024) per sector, you need to take into account the

M-O cartridge’s high-level format that will be used with Isis. An M-O cartridge that will be

used with Isis must be high-level formatted with one DOS hard disk partition.

To high-level format an M-O cartridge, refer to C.4.3.2 (‘Formatting the M-O after Backing

up Your M-O’s Data’) on page 32.

If you believe your data disk already has been high-level formatted with what AFDISK

calls Standard Hard Disk Format (

i.e., the DOS high-level format), then exit Windows and

re-start Windows 95 with the WIN/D:F command. You should now be able to read the

1024 Byte/sector M-O disk, albeit slowly.

C.4.3.1 Backing Up Your M-O Data Before Reformatting

Because formatting destroys any data existing on the cartridge, you will want to back up

your M-O data before formatting.

To back up your data from the M-O

1. With the M-O cartridge in Drive E:, exit Windows 95. (When the message comes

up that allows you to go to DOS, close Windows completely and go to DOS — not

just the DOS shell).

2. In DOS, use COPY or XCOPY to copy your files from your M-O to your D: drive.
