Drive/Diskette Compatibility - Epson Equity III User Manual

either type of drive, but write to that diskette only when it is in a 1.2MB
drive. If you write to it in a 360KB drive, it may become unusable in both
drives.
You can use a 1.2MB drive to read data from a double-density disk-
ette that was formatted in a 360KB drive (for example, if you want to
copy files from it). But do not write to this diskette while it is in a 1.2MB
drive. If you do, the diskette may become unusable in both drives.
Here is a rule of thumb to follow: do not write to a diskette unless it
was formatted in that drive (or the same type of drive on another com-
puter). To avoid accidentally storing data on a diskette while it is in the
wrong drive, you can place a write-protect tab on it before you insert it
in the drive (see 'Write-protecting diskettes" below).
Because of these incompatibilities, always be sure to indicate density
and drive type when you label your diskettes.

*Do not write to a double-density diskette in a 1.2MB drive unless it was formatted
in that drive as a 360KB (or 320KB) diskette.
Note: Both types of drives on the Equity III can read and write to single-
sided double-density diskettes. However, do not write to a single-
sided diskette while it is in a 1.2MB drive unless it was formatted in
that drive as a double-density diskette.
If you have both drive types (360KB and 1.2MB), you can copy files
from one drive to another as long as the right diskette type is in each
drive. You can also copy files between a hard disk and any type of disk-
ette. See your MS-DOS or other software manual for instructions on
how to copy files.
