Choosing Diskettes For The Equity Iii; Drive And Diskette Incompatibilities - Epson Equity III User Manual

Choosing Diskettes for the Equity III+

When you buy diskettes, be sure to choose high-quality diskettes with
reinforced hub rings. The added reliability is well worth the extra cost. You
also need to make sure you buy the proper format type for the drive(s) in
your system.
The top floppy disk drive on the Equity III+ has a capacity of 1.2MB
(megabytes) and uses 5%inch, high-density, soft-sectored, 96 TPI(tracks per
inch) diskettes. Each high-density diskette can hold 1.2MB of data, or about
450 pages of text. (One megabyte equals 1,048,576 bytes.) These diskettes are
compatible with those the IBM PC AT uses, so you can use diskettes pre-
pared by one computer on the other.
If you have a second 1.2MB floppy disk drive, use the same high-density
diskettes described above.
If you have a second floppy disk drive that has a capacity of 360KB
(kilobytes), use 5%inch, double-sided, double-density, soft-sectored, 48 TPI
diskettes in this drive. Each double-density diskette can hold 360KB of data,
the equivalent of about 150 pages of text. (One kilobyte equals 1024 bytes.)
These diskettes are compatible with those the IBM PC uses, so you can use
diskettes prepared by one computer on the other.
If you have a floppy disk drive that has a capacity of 720KB, use 3%
inch, double-sided, high-density, soft-sectored, 135 TPI diskettes. Each
diskette holds 720KB of data, approximately 300 pages of text.
You need to format new diskettes before you can use them with an
operating system. Formatting erases all the data on a diskette and prepares it
to receive new data, so be sure to format only new blank diskettes or disk-
ettes that contain data you want to erase. Refer to your MS-DOS (or other
operating system) manual for instructions on how to format diskettes.

Drive and diskette incompatibilities

Because of their size difference, you cannot use a 3%inch diskette in a
incompatibilities between the 1.2MB and 360KB drives and the diskettes
they use. These incompatibilities apply to diskettes from other compatible
computers as well.
You cannot use high-density diskettes in a 360KB drive. However, you
can use double-density diskettes in a 1.2MB drive under the circumstances
described below.
