Fsck Error Conditions
Fsck - UNIX File System Checker
A directory entry F has an inode I without allocate mode bits. The owner 0, mode M, size S,
modify time T, and file name F are printed.
Possible responses to the REMOVE prompt are:

the directory entry F is removed.
NO ignore this error condition.

Check Connectivity
This phase concerns itself with the directory connectivity seen in Phase 2. This section lists
error conditions resulting from unreferenced directories, and missing or full
'0"+
found direc-
tories.
DIRECTORY
D
CORRUPTED (SALVAGE)
A directory with an inconsistent internal state has been found. This error is fatal if the file sys-
tem is being preen'ed.
Possible responses to the SALVAGE prompt are:
YES
throwaway all entries up to the next 512-byte boundary. This rather drastic action can
throwaway up to 42 entries, and should be taken only after other recovery efforts have
failed.
NO Skip up to the next 512-byte boundary and resume reading, but do not modify the direc-
tory.
UNREF DIR 1==1 OWNER== 0 MODE==M SIZE==S MTIME== T (RECONNECT)
The directory inode I was not connected to a directory entry when the file system was
traversed. The owner 0, mode M, size S, and modify time T of directory inode I are printed.
When preen'ing, the directory is reconnected if its size is non-zero, otherwise it is cleared.
