Floppy Disk Problems

If you have trouble with a diskette, check the following questions:

Is the diskette damaged? Copy the diskette and repeat the operation that

caused the problem using the copy. (If you have trouble copying the

entire diskette, some of the sectors may be bad. Try to copy single files

with the Copy command.) If the operation works using the copy, the

original diskette is probably damaged. Make another copy to use as a

backup.

Have you inserted the right type of diskette? The diskette type is nor-

mally shown on the manufacturer’s label. In the top drive, which has a

storage capacity of 1.2MB,

use

5%inch,

double-sided, high-density,

96 TPI, soft-sectored diskettes. If you have a second floppy disk drive

that is also 1.2MB, use the same type of diskettes in this drive.

If you have a second floppy disk drive that has a storage capacity of

360KB, use double-sided, double-density, 48 TPI, soft-sectored diskettes

in this drive.

If you have a 720KB floppy disk drive, use double-sided, high-density,

135 TPI, soft-sectored diskettes.

The three diskette types are not interchangeable between the different

types of drives. The 720KB drives can use only the

3%inch

diskettes.

You cannot read or write to a high-density diskette in a 360KB drive.

You can read a double-density diskette in a 1.2MB drive, but do not

write to it unless you have formatted it in a 1 .ZMB drive as a 360KB (or

320KB) diskette. See “Choosing Diskettes for the Equity III+” and

“Drive and diskette incompatibilities” in Chapter 3.

Is the diskette write-protected? There may be a write-protect tab over the

notch on the side of the diskette

(5Gnch)

or the write-protect switch

may be set (on a

31/z-inch

diskette). Before you remove the tab or move

the switch, check the directory to see what files the diskette contains-it

may contain information you do not want to change or lose. (Your oper-

ating system manual describes how to display a directory) Although you

should normally write-protect all program diskettes, some programs

store temporary files on the diskette. These programs do not work if you

write-protect the diskette.
