I have (had) a NetBSD 2.x machine using a 40GB drive and ffsv2.
However something failed and I get errors like these on the console:

Jan  2 13:20:00  /netbsd: wd1a: error reading fsbn 128 of 128-143 (wd1 bn
191; cn 0 tn 3 sn 2), retrying

I've installed NetBSD 3.0 on another drive and been able to mount and copy
everything i want except the a-partition, I've tried to run fsck on it but
that couldn't find the super-block.

Are there any way I can figure out the position of one of the backup
super-blocks? Or am I screwed anyway? It's not the end of the world if I
can't fix this but it would be nice to have some of the files from /etc.

Thanks in advance.
