Epson Equity 320SX PLUS - Manual (Page 61)

360KB drive-Use 5 1/4-inch, double-sided, double-density,
48 TPI, 360KB diskettes. (You can also use single-sided,
160KB or 180KB diskettes.) These diskettes contain 40
tracks per side and 8 or 9 sectors per track. With 8 sectors
per track, a diskette holds up to 320KB. With 9 sectors per
track, a diskette holds up to 360KB of information, which
is approximately 150 pages of text.
Note
You must format a new diskette before you can store data
on it. See “Formatting Diskettes,” later in this section.
Drive and diskette incompatibilities
If your computer has more than one type of diskette drive, or
if you use different types of diskettes, you need to be aware of
certain incompatibilities between the drives and diskettes.
Because of the type and size differences, you cannot use a
31/2-inch
diskette in a 51/4inch drive or vice versa. There are
also limitations on using diskettes that are the same size as
the drive but have different capacities. The following tables
summarize the possibilities and limitations.

to read it or write to it in a 360KB drive later.
