When ls tries to execute stuff fmom the listing, that's most definitely
trash. That was one of the things I first noticed.

No. The boot block is sector 0, AKA the MBR. Which is outside the
partition table. (Partitions start at sector 1.) In the dual boot
configuration, such as the one that this was discovered on, what happens
is this.

LILO boot: dos
Loading dos...

Starting Windows 95...
(pop up stupid screen, no response after that.)

LILO boot: linux
Loading linux...
(you know the routine. boots clean.)

Besides, the corruption is not the partition table, but the data on the
partition. The actual filesystem. I had no problems creating, deleting,
and messing around with partitions. But the filesystem would not hold.
(This has been attributed to a bug in the drive's firmware.) This resulted
in seven hard locks, and many errors while running involving 03:01. ;P
