Subject: problems with using 1.3 FFS with Pacific Peripherals Overdrive

I have been unable to get the Workbench 1.3 Fast File System (FFS) to
work with my Pacific Peripherals Overdrive hardcard on my Amiga 2000.

I have a Seagate ST157N hard disk attached to the hard card.  I
formatted the drive with two partitions: one with the standard file
system, and one with the Fast File System (FFS).  The partition with
the standard file system works fine.  But every time I try to copy
files from a floppy disk drive to the FFS partition, the Amiga
crashes; sometimes it freezes up, other times it gurus.  (If I try to
copy files from the standard hard disk partition to the FFS partition,
that also causes gurus, but only intermittently.)

I called Pacific Peripherals about this.  They suggested that
FastMemFirst should not be used (the Workbench 1.3 version is
apparently buggy), and also suggested the following Mountlist entry
for the FFS partition:

   DH1:	Device = overdrive.device
	   Unit = 1
	   Flags = 0
	   Surfaces = 6
	   BlocksPerTrack = 26
	   Reserved = 2
	   Interleave = 0
	   LowCyl = 57  ;  HighCyl = 607
	   Buffers = 5
	   BufMemType = 3
	   GlobVec = -1
	   FileSystem = L:FastFileSystem
	   Mount = 0
	   StackSize = 0x800
	   MaxTransfer = 127000
   #


However, neither of these suggestions has fixed the problem.

Has anyone had better luck with FFS on a Pacific Peripherals
Overdrive?  Does anyone know what might be causing these gurus on my
Amiga?  Any help would be most appreciated!!!
