  recovering from corrupt directory? 
 The Question is:
 
I'm unable to access several directories -
I get the following message:
 
$ dir
%DIRECT-E-OPENIN, error opening DUB0:[TOOLS.HPL.LISTINGS]*.*;* as input
-RMS-E-FND, ACP file or directory lookup failed
-SYSTEM-F-FORCEDERROR, forced error flagged in last sector read
 
 
Even though the directories appear to be there:
 
$ dir /d
 
Directory DUB0:[TOOLS.HPL]
 
DOCUMENT.DIR;1       18-APR-1990 23:47:08.24
EXECUTABLE.DIR;1     18-APR-1990 23:47:09.29
LISTINGS.DIR;1       18-APR-1990 23:47:11.04
OBJECT.DIR;1         18-APR-1990 23:47:22.22
SOURCE.DIR;1         18-APR-1990 23:47:30.40
TEST.DIR;1           18-APR-1990 23:47:47.60
 
Total of 6 files.
 
 
Have tried using the DFU utilities but no
errors are rported nor can
 I delete the directories.
 
analyze/disk/repair encounters bad directories but
can do nothing to rpair them.
 
What would be my options on getting rid of these
directories and possibly restoring from tape backups?
 
Thanks.

 The Answer is:
 
  Yes, the directory files are still there, but the (part of) the contents
  are no longer readable. Sometimes you can recover the still-readable part,
  but for directories this step can be avoided as they can be recovered
  using existing tools.  The file entries and the files contents still exist
  within the disk file structure, though access is somewhat more difficult.
 
  Perform a ANALYZE/DISK/REPAIR to repair any existing defects in the disk
  volume structure, then RENAME the existing [000000]SYSLOST.DIR, or look
  through any [SYSLOST] contents and relocate or delete any files in the
  directory as appropriate.  Issue SET FILE/NODIRECTORY against the
  broken directory.  DELETE the broken directory.  Now reissue the
  ANALYZE/DISK/REPAIR command.  The files that were formerly in the broken
  directory will now be relocated into [SYSLOST].  Rename the SYSLOST.DIR
  to become the lost directory, and reset the directory protection and the
  directory ownership to match that of the former directory.
