SET DSKERR causes the computer to report the location of any hard errors the
diagnostic program finds. If you don’t use SET DSKERR, the diagnostic tells you only
that an error occurred, not where on the disk it happened. You must run the diagnostic
program from the same job where you used SET DSKERR.
The next two sections discuss two very useful diagnostic programs, REDALL and
DSKANA. You can find more information on disk diagnostic programs in the
System
Operator’s Guide
and the
AMOS User’s Guide
.
The REDALL Command
REDALL reads every block of data—or the number of blocks you choose—on the disk
you specify, and reports any hard errors. It does not alter the data on your disk.
REDALL works on both hard disks and diskettes. It is a good idea to run REDALL for
each disk on your computer occasionally, possibly once a week. That way, if any disk
problems develop, you can be sure of detecting them quickly.
To use REDALL, perform these steps:
1.To read all the blocks on a disk, enter REDALL followed by the device name of
the disk you want to read. For example:
REDALL DSK2:
RETURN
2.If you don’t want REDALL to read all blocks on the disk, follow the disk
specification with the number of blocks you want read:
REDALL DSK2:100
RETURN
Do not put a space between the device specification and the number of blocks.
The command above tells REDALL to read the first 100 blocks on DSK2:.
3.REDALL now tells you the number of blocks it is reading. For example:
REDALL DSK2:
RETURN
Reading 13800 blocks
EXIT
4.REDALL ends when it finishes reading the blocks. If any errors occur, REDALL
displays the appropriate error message on your screen.
