Sorry to bring up the subject again, but I'm just a little
bit worried for my filesystem...
The situation is: I have a "normal" MFM hard disk (Seagate 251-1),
which I have low-level formatted with my AMI-BIOS, and at the same
time marked the bad tracks.
The question is: Should mkfs -c find these bad tracks and create
a .badblocks file, or are they somehow automatically ignored because
of the low-level format? It doesn't, there's no such file on my root
partition, though I know the bad blocks exist. With MSDOS, CHKDSK
shows that there are bad sectors. (And I did use the -c switch,
and .badblocks does appear on corrupt floppies.)
Another thing, what exactly does it mean that the kernel doesn't
support the ext fs as a root filesystem? Is it impossible to
have an ext fs partition configured as the rootdev in the boot
image, or is it only impossible to boot with the image itself
being on an ext fs?
I'm getting mixed up here a bit... But I was thinking of a setup
which would consist of two partitions: The first would be ~300k
and contain a minix fs, with only the boot image on it. The second
would be an ext fs, containing everything else, and the boot image
would be configured as the second partition as the rootdev...
(I want to boot without floppies.)
If this makes any sense to anyone, drop me a letter or followup
this article and enlighten me on the subject... Thanks.
