:Also happens on IBM Netfinity servers with aic7896/97 controllers. It
:*may* be the case that this only happens with certain Adaptec BIOS
:versions, but it's very real.
I started getting this on DELL's a year and a half ago. The
dangerously dedicated partition was to blame (which is what eventually
led to my fixing the disklabel auto code). Well, ok, the Adaptec BIOS
was to blame, but there isn't much we can do about it so...
In my case it wasn't enough to repartition the disk. The old
data still screwed up the BIOS. I had to physically wipe (with dd)
the first couple of sectors before repartitioning it use the
fdisk -BI / disklabel -r -w da0s1 auto combination.
