You can use a double-density diskette in a 1.2MB drive if you format

it as a 360KB (or 320KB) diskette in the 1.2MB drive first. (Your MS-

DOS or other operating system manual explains how to format a disk-

ette in the density you choose.) After you do this, you can read data

from it in both drive types, but write to it 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.

In general, do not write to a diskette in a drive unless it was format-

ted in that drive (or the same type of drive on another computer). 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” in this chapter). Because of these

incompatibilities, always be sure to indicate density and drive type when

you label your diskettes.

Equity II can read and write

to single-sided, double-density diskettes. But do not write to a

single-sided diskette while it is in a 1.2MB drive unless it was for-

matted in a 1.2MB drive as a single-sided, double-density diskette.

If you have both drive types (one 360KB and

one

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

diskette. See your MS-DOS or other software manual for instructions on

how to copy files.
