Diskette Problems

You may see the following message if you are having trouble with a diskette or your diskette drive:

601 DISKETTE ERROR

If you see this message or have trouble accessing data on a diskette, try the following steps:

1.Did you turn down the diskette drive latch on a 5 %-inch drive to secure the diskette in the drive? See Chapter 3 for more information.

2.You may have inserted the diskette 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. Be sure to turn down the diskette drive latch. (See Chapter 3 for detailed instructions on inserting and removing diskettes.)

3.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.
