FORMAT
/VERIFY writes a bit pattern to each block on a volume and then reads that
pattern. After the verification procedure is complete, RT–11 displays at the
terminal the block number of each block to which it could not write or from
which it could not read.
/VERIFY:ONLY only verifies a volume and replaces bad blocks it cannot read;
it does not format that volume; but its verification procedure is destructive of
information already on the volume.
The following command formats and verifies an RX33 diskette in drive unit 1:
.FORMAT/VERIFY DU1:
DU2:/FORMAT-Are you sure? Y
?FORMAT-I-Formatting complete
PATTERN 8
?FORMAT-I-Verification complete
The next command only verifies an RL02 disk in drive unit 2:
.FORMAT/VERIFY:ONLY DL2:
DY0:/VERIFY-Are you sure? Y
PATTERN 8
?FORMAT-I-Verification complete
/WAIT
Initiates the formatting operation, then pauses before formatting begins to wait
for you to change volumes. The /WAIT option is useful for single-drive systems.
After RT–11 accepts your command line, it pauses and displays the message
Continue?. At this time, you can exchange volumes. When the new disk is
loaded, type Y
RETURN
to resume the operation. If you type N
RETURN
or press
CTRL/C
, the operation is not performed and control returns to the monitor.
When formatting completes, RT–11 pauses again while you remount the system
volume. Mount the system volume and type Y
RETURN
to terminate the
formatting operation. If you type any other response, RT–11 prompts you to
mount the system volume until you type Y. RT–11 then displays the monitor
prompt.
The following command uses the /WAIT option to format an RX33 diskette:
.FORMAT/WAIT DU1:
DU1:/FORMAT-Are you sure? Y
Mount input volume in <device>; Continue? Y
?FORMAT-I-Formatting complete
Mount system volume in <device>; Continue? Y
