I just bought a Fujutsu DynaMO 640SE magneto optical disk and am
having trouble getting it to work. I have made progress by moving
from a 2.0.33 to a 2.0.34 kernel and am now able to partition it, but
it gets errors partway into mke2fs when writing inode tables. Two
different disks will fail at different inodes, and the same disk will
fail at different inodes on different runs. Before the 2.0.34 kernel
and 2048 byte sector patches, the drive was wrongly recognized as a
39mb removable drive. Fdisk now correctly sees it with 620k 1k blocks.
When I installed the driver and utilities from the Fujitsu CDROM onto
Windows 3.1 and did a low level format and DOS format from Windows, I
was able to restore a 250mb backup tape to it and it worked fine.
Then tried another low level format and DOS format from Windows, then
came over and looked at it with Linux cfdisk, it only showed cylinders
1-151 of 606 mapped to a single partition. Tried deleteing partition
and making the full disk a Linux type 83 partition, and then tried
mke2fs once again, and it still got the errors.

I edited these slightly to make them less than 80 chars wide. This is
the last one in the log. There are over 28k instances of this

going up to here (4260480).
