- Well, I don't get it because you go to some trouble to explain that the
- bad144 area is contained within the C partition - then..

- 80640 + 205240 = 285880 (which is the size of the D partition, no?)
-
- Thus it seems to me that this disktab entry doesn't leave any space
- for the bad144 sector markings. My *guess* at the 5 cylinder number is
- that 386BSD will try to re-map sectors from that 5 cylinders of free
- sectors onto the bad sectors, this allows for 'perfect' media..
-
- Maybe this is in the FAQ, if so please ignore this. If not, can someone
- add something to the FAQ about how the bad sector mapping is handled,
- how your disktab entry should look when its done (with some attention
- given to the fact that IDE drives should not use bad sector mapping and
- how this is done)?
-
- Thanks (especially to the creators of 386bsd!)
