Floppy Disk Drive (FD) Diagnostics
The FD diagnostics TEST FLOPPY 1 can be used to isolate faults to the diskette, floppy disk drive, or
floppy disk controller. To run this test, at the @ prompt, enter:
TEST FLOP 1 (or TE F 1)
This test reads the entire diskette, and if there are errors, the system responds with:
or,
When the diagnostic completes, the system responds:
If the system fails to read or write information on the diskette on the first attempt, but is successful in
a subsequent attempt, the system records a soft error. Soft errors may be caused by diskette wear,
contamination on the recording surface, or aging of the floppy disk drive head.
Refer to the INSTALLATION chapter for information about the floppy disk write-protect feature.

Hard Disk (HD) Drive Diagnostics (DEX)
The purpose of the DEX command is to “exercise” the disks; hence its name Disk EXerciser. Since a
small percentage of disk sectors are accessed in the course of normal system operation, and since disk
error handling cannot be performed for any sectors that are never accessed, DEX provides an orderly
and efficient means to read all disk sectors.
Each disk is divided into five regions, as follows:
Region 1
Critical sectors
Region 2
File system
Region 4
