that's 64 heads..
this is the LAST HEAD
i.e. 0-63
dos (of course!) numbers it;s sectors 1-32
so the last sector is 32 giving 32 sectors
the geometry to use is therefore:
64 heads 32 sectors..
the cylinders can effectively be ignored.. nothing uses it.. :)

but it DID reboot, right?
the funny noises were probably hardware recalibrates
as it tried to recover from an error.

vm?
the HARDWARE FAILURE messages from the SCSI would be useful..
POSSIBLY you might have made the partition too big..
on bootop the drive's total available secotrs should be reported..
do you go beyond this?

that's going to MAYBE work.... (depending on how you do it
it might only access a part of your drive..)
If you have errors on your SWAP partition, that would explain the vm problem..
fsck can use a LOT of vm..

you may need to turn on error recovery
