[NTLUG:Discuss] can't boot

[Jeff Demel]

It's formatted ext3.  The kernel does support it, as hda1 is the same.
Plus, it's been up and running for a month or two now.

I don't know fchk and it doesn't appear to be a command Knoppix understands,
but when I try and run fsck it gives me a permission denied error.  I
believe this is something with Knoppix that I don't understand.  I don't
know why I'm not root automatically, but that's apparently the way it is,
and I have no idea what root password it's looking for.  The original root
password doesn't appear to work.

I really don't want to zero out the drive and start over.  Maybe as a last
resort, but there's data on there I don't really want to lose.

some possibilities:

1. Which file system are you using? You may not have support for it in 
the kernel.
2.  Is hda2 swap? You may not have initialized it if you partitioned the 
dive by hand.
3. If it's  the boot partition, which it doesn't appear to be, which 
file system did you use? If you used ext2, then you can fchk it. 4. If it's
a bad section of disk, you should hear the read arm thrashing 
about. If not, it probably isn't the hard drive.
5. You may need to zero out you drive and start over. Try 
http://diskzapper.com/download and you can find a free utility to clear 
the disk completely.

someone else may need to weigh in on this.
