I think you are running into a block size issue. I notice your fs
block size is only 1024. See if you can mount it on an IDE CDROM
drive. I ran into the same problem with file systems with a block
size of 1024 when using the ide-scsi module because it saw the device
bs as being 4096. You cannot mount a file system with block size
smaller than the device. I would unload the the ide-scsi modules and
mount it as /dev/hdxx and it mounted just fine. I started specifying
the bs to be 4k when creating the file system to backup to CD and the
problem went away. The error message was deceiving. I did not
discover what it was until I left X windows and tried it from the
console and finally got an error relating to block size.
