- Erm..someone - can't remember who - was asking about a hard
- disc error along the lines of "error at 4/0000C00"...the bad news is
- that C00 is where FileCore puts the boot block, and if it can't read
- this, it won't access the disc.
-
- As someone suggested, re-formatting might help - perhaps even
- just format the first track, and you should keep most of your data,
- as the root directory is miles away in the middle of the disc. You
- could have trouble if a directory is in the first track cos you'll end
- up with a slightly knackered disc which can't be fixed by FileCore.
- Best thing to do is mark all the first track sectors as defects before
- you re-format it, and this will tell you which files (if any) use the
- first track. Unfortunately you then can't use the first track anymore.
-
- Or you could get a disc editor and try re-writing the sector back
- (with the correct values for the boot block - see PRMs).
-
- Anyway, by far the best thing to reformat. However, if that doesn't
- fix it and you've got a persistent physical error at address &C00,
- then sadly your disc is shafted, and won't work with FileCore, and
- hence Risc OS.
-
- I'm sure someone at Acorn will correct me if I'm wrong...
