INITIALIZE
prompting ends and any blocks not placed in the replacement table are marked
as FILE.BAD.
If you enter
RETURN
at any time, RT–11 places all bad blocks you have not entered
into the replacement table, starting with the first on the disk, until the table
is full. RT–11 assigns the name FILE.BAD to any remaining bad blocks and
prompting ends.
If you use /NOQUERY with /REPLACE, and there is a replacement table
overflow, the effect will be as if you had entered
RETURN
in response to the first
Replace block prompt.
/RESTORE
Uninitializes a volume. That is, you can use this option to restore the directory
and files that were present on the volume before the previous initialization.
However, you can use /RESTORE only if no files have been transferred to
the volume since the last time it was initialized. And, you cannot restore
volumes that support bad-block replacement, if bad blocks were found during
initialization.
The /RESTORE option does not restore the boot blocks; so if you use /RESTORE
to restore a previously bootable volume, use the COPY/BOOT command to make
the volume bootable again.
/SEGMENTS:value
Specifies directory segments when you initialize a volume. Use this option if you
need to change the number of directory segments on a disk.
The number of segments in the directory establishes the number of files that can
be stored on a device. RT–11 allows a maximum of 72 files for each directory
segment and 31 directory segments for each device.
The value argument specifies the number of directory segments. The valid range
for value is from 1 to 31
10
. The following table shows the default values of value
for standard RT–11 devices.
