[comp.sys.mac.misc] How to unallocate an allocated block?

bhatlas@pyrite.som.cwru.edu (Sunil Bhatla) (10/02/90)

Folks,

I just purchased DiskExpress 2.04, and gleefully started to optimize
my 80 Mb hard drive.  However, there seems to a problem with my drive
directory that needs fixing before DiskExpress can work.  I get the
following error message when verifying the directory:

     "A file with ID 13,266 has allocation blocks allocated to it but
      the main file information is missing"

I used Disk First Aid but it says no repairs are necessary.  Now,
apparently this file (ID 13,266) is long gone, but the directory still
has some blocks allocated to the file.  How can I free them?  I DON'T
want to recreate the directory by erasing the disk, since my only back
up method is via floppies!

Can I use ResEdit or SUM's disk editor to do the job?

Please help?
