Diskette Problems

If you have trouble accessing data on a diskette, try the

following steps:

Is the diskette inserted properly? You may have inserted it

upside-down or it may not be inserted all the way. Remove

the diskette from the drive and reinsert it with the label

facing up. (See Chapter 3 for detailed instructions on

inserting and removing diskettes.)

If reinserting the diskette does not solve the problem and

you have access to another diskette drive of the same type,

place the diskette in the other drive and repeat the

operation. If you can successfully repeat the operation in the

new drive, the trouble may be in your diskette drive. See

“Diskette Drive Problems,” below.

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

type normally appears on the manufacturer’s label. Here are

the guidelines:

In a drive that has a storage capacity of 1.44MB, such as

drive A, use 3

‘/z-inch,

double-sided, high-density, 135

TPI diskettes. This type of drive can also read and write

to 720KB diskettes.

In a drive that has a storage capacity of 720KB, use

‘/z-inch,

double-sided, double-density, 135 TPI

diskettes. You cannot use 1.44MB diskettes in this

drive.

In a drive that has a storage capacity of 1.2MB, use

l/4-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.
