Epson 20 Manuel D’Utilisation

If you have trouble with one of your diskettes, see if any of the

following questions apply:

1. Is the diskette damaged? To find out, make a copy of the diskette.

Using this copy, repeat the operation that caused the problem. If
the operation works using the copy diskette, the original diskette

is probably damaged. Make another copy to use as a backup.

If you have trouble copying the entire diskette, some of the

sectors may be bad. Try using the COPY command to copy one

file at a time. If the diskette is copy-protected, you cannot copy it.

2. Have you inserted the right type of diskette? The diskette type

normally appears on the manufacturer’s label. In the top drive,
which has a storage capacity of 1.2MB, use 5¼-inch, double-

sided, high-density, 96 TPI diskettes. You can also use 360KB

diskettes in this drive, but if you write to a 360KB diskette in this
drive, you may have trouble using the diskette in a 360KB drive
later.

If you have a second diskette drive that is also 1.2MB, follow the

same guidelines as above.

If you have a second diskette drive that has a storage capacity of

360KB, use 5¼-inch, double-sided, double-density, 48 TPI
diskettes in this drive. You cannot use 1.2MB diskettes in this

drive.

If you have a 3½-inch, 720KB diskette drive, use double-sided,

double-density, 135 TPI diskettes. You cannot use 1.44MB

diskettes in this drive.

If you have a 3½-inch, 1.44MB diskette drive, use double-sided,

high-density, 135 TPI diskettes. This type of drive can also read
and write to 720KB diskettes.

See “Types of Diskette Drives” in Chapter 4 for more

information.
