Boot Error -- Why?

Post #1 of 3 (413 views)

I'm using the 2.6.5 kernel with the universal stage 3 installer cd. After
installing and making the root partition ext3 with 'mke2fs -j /dev/hda13', I
get this error when booting:

Checking all filesystems...
Fsck.ext2: Bad magic number in super-block while trying to open /dev/hda11

(note: /dev/hda11 is my boot-block -- should that be included in fstab on
the ppc?)

"The super-block could not be read or does not describe a correct ext2
filesystem."

What's causing this error and what might be the solution? Thanks.

Ed

Just a suggestion as you may rightfully have whole 13 partitions.
PS:somewhere saw an article recommending doing: dd if=/dev/zero
of=/dev/hdaX on a new install partition and leave it to run for some 20
seconds just to override (old data-super block) in the initial portion
of the partition.

That would be as a pre-install step. It should wipe the partition clean
if you leave it run to completion.
