I had the same problem. The second media works, the first got
screwed up? I can't reproduce the problem now.

The media gets destroyed after partitioning and running mke2fs.
I can't believe it myself - but have no other explanation.

When the media was broken I got:
<7>VFS: Disk change detected on device ide0(3,64)
<6> /dev/ide/host0/bus0/target1/lun0:<7>LDM:  DEBUG (ldm.c, 877):
 validate_partition_table: Found basic MS-DOS partition, not a dynamic
disk.

<4> p1 p2 p3 p4
[and so on with funny device numbers up to 3,93]

cat /proc/partitions
   3    64      98288 ide/host0/bus0/target1/lun0/disc
   3    65  272218546 ide/host0/bus0/target1/lun0/part1
   3    66  269488144 ide/host0/bus0/target1/lun0/part2
   3    67  699181456 ide/host0/bus0/target1/lun0/part3
   3    68      10668 ide/host0/bus0/target1/lun0/part4

Note: a new media has NO partition - it's a floppy.
Now is it possible that the media gets destroyed if the hardware
tries to seek to illegal positions?
