Help deleting directory incorrectly marked as Block Special File

["Tank (SPM)" <Tank_(_at_)_pg_(_dot_)_net>]

SOS.

We recently had our Newserver crash (INN v1.5.1) and the spool drive
failed to come back up, requiring a manual 'fsck'.

The wonderful operator on hand (no, it wasn't me) gave a 'fsck -y'.  
The drive was scanned, and presumably repaired.  However, a number of files
and directories (I think 3 in all) have been marked as Block Special Files
and assigned to device numbers which do not exist.  

I can't delete these files, so I can't recreate the directory.  This
results
in INN throttling anytime it receives a file which needs to be written
into the directory (which is now not seen as a directory).

Does anyone have any idea what I can do to get rid of these files aside
from
wiping the entire disk?  All variations of 'rm' I have tried have failed.

Thanks.
