Hallo All,

Some of you might remember that I had severe problems updating NetBSD 1.0
to -current. My system ran fine 1.0 (and for a while 1.0+)
When I build a new kernel it would abort with init dying.
When i builded fsck once and used it (on my working system) it wiped the
disk clean with the most fantastic garbage displays (bad this and that)
you have never seen before.
As it was time to grow I got a new 1 Gb disk and moved the old primary
(Yes, IDE disk) to the secondary position. Rebuilding the boot disk
and putting the latest binary snapshot on it worked like a charm.
Now i looked at my 540Mb secondary disk and fsck again. Bad idea.
So I started playing around and think that the lba addressing screws up
the drive one way or the other.
Configuration is 486SX 8Mb, wd31000 prim, lps540a as secondary disk
and adaptec 1542b as scsi.
Here is some output from the various commands. If anybody knows what is
going on, please tell. 
(when using partition wd1e fsck goes bad on 1760, 1761 and following)
