Just for the sake of the completeness of the thread: The disk seems to be fully useable! I've dd'd the first 100 gigabytes full of zeroes and then filles the remaining 100 with bits from /dev/urandom. I then dd'd out the first 100 gb again and piped it trough od, just to see that it outputted 100 gb of suppressed lines identical to the first that just had zeroes in it. I didn't bother to check the entire remainder of the disk, but dd'd ot a couple of megabytes near the end of it, and saw that it was filled with appearently random bits. Appearently FreeBSD 5.x have no trouble with 137GB+ disks on 440BX chipsets :) Cheers, Svein Halvor
