If this does not work try replacing the disk. What I did was to replace the disk. The new disk happened to be the same model as the former. It's now working with no problems. I came to a conclusion that the former disk itself had problems, maybe bad sectors because I kept on seeing this, (da0:ncr0:0:0): Invalidating pack also vm_*something*: read error *something* : MEDIUM ERROR *something* Then afterwards, the disk goes silent and my FreeBSD hangs up of course since the disk is no longer running. > If your SCSI controller does not scan the SCSI BIOS during bootup you have > a bad Controller!
