I recently had a major disaster backing up my HD20. I was using HD
Backup 1.2 software. HD Backup backs up the HD by combining files
into and compressing them into the data fork of a "Storage File".
There is a storage file on every disk that is used in the backup.
Here's the rub; HD Backup saves a directory of these compressed, 
backed up files on the last disk of your back up set. Well, I
performed a backup, saved the backup directory onto my last disk and
went about my business. When I went to restore, my directory disk 
was zapped and thus has rendered my backup set useless. Efforts to
recover the "Storage Directory" with MacZap, Fedit and some others
have been fruitless. The program works great except for this catch.
It will also let you save the Backup directory on many different
disks, but unfortunately I saved the dir on only one disk. Now I 
can't read the storage dir and can't get to the backed up files.
HD Backup gives an "logical end of file reached during read 
operation" error when I try to read the Storage Dirs I recover
with MacZap. Occasionally I get a "general error: 1234" also.
Has anyone ever had this problem before? Does anyone know the
format for the HD Backup StorageDir file? Would there perhaps be a 
program which will read my backup set and rebuild a StorageDir
for me? Would there be any to remove the backed up files from the
data forks of the StorageFile(s)...
Thanks for any help
