fairly well, and includes protecting freed memory blocks to catch
free-memory reads (I think) and writes.
C++ may need minor source mods to track source file/lines for
new'd objects. Overall it works pretty well. See ports and also

If I remember correctly, you can read uncorrected sectors off of
ATA (maybe) and SCSI (I think), at least using CAM.
Quite honestly, I can see some use for this in HD's; I don't see
much use for it in floppies, except mayb

overhead on file-close-after-modify and create/delete, but not a lot. As a
side-benefit, recovery after a trashed FS is slightly easier since there's
more redundant information available (if the main directory sector/inode

hardware. This is quite easy, in fact, especially since ATAPI is
basically SCSI-over-IDE with a few twists.

Makes sense.
Shouldn't the mmap() return MAP_FAILED, probably with EACCES,
instead of causing a signal 10?

Ick. Polling == bad. Interrupts == good. This isn't a single-
tasking OS ala Win9x. This goes double for SCSI drivers, which are
inherently async and overlapped.
