Hello,
(I promise not to repeat this post 3 times!)
Somehow, for the nth time, I have managed to trash the super block of
one of my hard disk partitions. Is there any way I can restore the
super block? This partition contains my entire source tree, and would
be very time consuming to replace. "fsck -r /dev/hd6" reports "bad
magic number in super block - fatal".
Could the super block be trashed if the start sector is not even? I
remember seeing this as an incompatibility between 1.3 and 1.5. The
super block somehow got trashed around the time when I first booted
minix 1.5 up from a shoelace diskette (i.e. loaded on the fly).
related question: say I have 3 HD partitions mounted. I log out. Is
it safe to reboot at this time, or must all
partitions be umounted first?
How can this problem be prevented forever??
Thanks,
(waiting desperately)

I forgot to ask this in the original post:
Is there any way to introduce a filesystem on top of existing data?
i.e. my data is all there (checked it with de(1)). All I need is
something to lay down the filesystem structure around it.
Suggestions from filesystem gurus would be greatly appreciated!!
Thanks,
