usb/scsi mystery

[Tony Alfrey]

OK, here's the wierdness of the week award.

My box is all SCSI and has as many as 4 SCSI drives and a USB port for 
my CompactFlash reader.
If I hook up 3 SCSI drives, the USB device (the CompactFlash reader) 
appears as sdd and is easily mounted.  It appears properly on
cat /proc/scsi/scsi and
cat /proc/bus/usb/devices  and
fdisk -l
with a vfat filesystem

Now I plug in the 4th SCSI drive, reboot and the USB device appears as 
sde like it's supposed to, same messages as above (except it's now 
sde).  But trying to mount it gives the typical "bad superblocks or 
wrong filesystem type" message and dmesg gives

fatfs: bogus cluster size
VFS: Can't find a valid MSDOS filesystem on dev 08:40.

Any SCSI/usb experts have a clue here??
Thanks very much in advance.
