[comp.sys.apple2] HD help PLEASE!!

Hi again, guys.  I'm back again, and I have another problem to solve.

This one involves an error on my fourth partition of my 100 meg HD.
It is a 12 meg partition, and I have crashed both the finder and Prosel-16
trying to copy a file from another partition to the fourth partition.
The error message that GS/OS gives right before it crashes is:
'System Error.	Cannot complete operation.  #804B'.  From Prosel, it just
goes 'boing' and doesn't have any message.  I would try Copy II Plus, but
I'm afraid of what it could do to my HD, so I'm staying clear of it.
I have verified the partition (from both the finder and Prosel-16) and
all blocks appear to be well.  I can read files from the partition, and
can write some files, but it seems like very large files (400k+) get
yakked on, since GS/OS tries to start it in the longest contiguous
segment of free space (or something like that, I believe).

Anyway, I have the distinct feeling that I have a couple bad blocks,
despite the verdicts of GS/OS and Prosel.  Has anyone had similar problems,
or can tell me what error #804B means in GS/OS-speak?  More importantly,
does anyone have a solution?  This is quite scary, considering that I
haven't made a backup since mid-September...

My setup is:  Apple IIGS Rom 01, 1.25meg Apple Expansion RAM, TWGS 7.0Mhz,
	      Apple DMA SCSI, POWERDrive 100meg HD, 1 3.5 and 1 unused 5.25.

Please help.

Thanks in advance,

    According to the Error Codes CDA, GS/OS error $4B (which I assume is the
same as error $804B) means "Bad Storage Type".  Maybe one of the volume bits
has been corrupted, and the Finder or Prosel is trying to write the file
"past" the end of the disk (and thus dumping your file into a Virtual Hole). 
Backup all your files on that partition onto another partition (that works),
re-format the disk, and use Prosel to lock out any bad blocks (Volume Repair
will do the job).  Hope that works.
