I've even unmounted the filesystem and tried mounting it again. Now I can't
even mount it without generating the error.
It seems like once I get the "ATA: abnormal status 0x59 on port 0xEFE7" error
the device becomes completely inaccessible.
Whereas before I get the "abnormal status" error I can mount the filesystem,
and read some of the directories just fine. Even once I hit the bad section I
can still access the good areas. It's only once I've hit the bad section
enough to trigger this message that the entire disk becomes inaccessible.

Well using "dd bs=512 if=/dev/sda4 of=/dev/null" I see errors on every block.
The errors below are from the dd. Notice the errors are for every logical
block starting at block 1.
I haven't gotten to writing a program to use O_DIRECT yet. But this is a
pretty strong indictment. Since the filesystem worked fine before the error I
know the superblock can be read at least.
