[comp.sys.apple2] HELP!: Bad block trouble on HD

HELP!!!

I've got a small problem that's a big problem.  I was working on my GS last
night, when I went to through some files in the trash, it asked my to insert 
the disk that the files were on.  BUT, the files were on a partition on my 
cartridge hard drive and it WAS in the drive!  I quickly discovered that I had 
some bad blocks on that partition. AND the bad blocks were #2 and #9!!!!
(and some other, less important blocks).  Now, since the block #2 is bad, that
partition is not recognized!  I went into SPY.EDIT (a block editor) and found
that everything else was there but it couldn't read block 2 or 9.

I know that everything else is still on the partition but I can't get to it
because the header is trashed.  Is there a program that will reconstruct the
header in block 2?  Or at least be able to save all the files off that
partition (so I could re-format etc... that partition).

Thanks for ANY help...

P.S. NO, I don't have any backups of that partition.  I just got the drive
about 2 weeks ago, or so, and I haven't had the time or resources to start
a routine backup schedule.

Yuppers, sure there's a way -- there exist several utilities to reconstruct
damaged disk directories and bitmaps.  The one I (and most people) prefer is
ProSel; the 8-bit version is called "Mister Fixit", and the GS/OS version is
"Volume Repair".  Both have similar capabilities.  Basically you let it analyze
your volume in "M>ain directory repair" mode (tell it your bitmap is NOT valid,
since block 9 is also damaged), and then you go off and watch TV for awhile. 
The program can (usually) reconstruct all SUBDIRECTORIES on your disk; however,
any files that were in the root (such as PRODOS, FINDER.DATA, things like that)
will be lost.  If you've organized your hard disk in a "good" manner, the files
on the root will just be generic system files (PRODOS and the like) and you'll
have lost very little data.

As I understand it, Quality Computers' Bag of Tricks I and II also have similar
repair modes ("FixCat", I think it's called), but I've never used either one,
I'm afraid.

Good luck!
