REBUILD - Rebuild a File System

The REBUILD sub command rebuilds a file system that was not dismounted correctly.  Such a file system cannot be written to until it is rebuilt.

Error Messages

Disk is read-only

This indicates that the disk is read-only.  To rebuild a disk, Init must be able to write to it.

File system structure corruption found - run recovery process

The rebuild finished but there were some instances of data corruption that Init cannot fix.  After UOS starts, run the recovery program to fix the data.

Not a valid file system

The disk you specified does not have a UOS file system and therefore cannot be rebuilt.
