Following is relevant dmesg pieces from my dmesg output: Hmm, are you sure you want to WRITE all those zeros to your disk ?? However it should not hang before the end of disk is reached that is. Have you tried reading all of the disk instead, does that hang ?? The degradation is probably becuse the transferrate of the disk slows down as you get closer to the center of the disk. Have you anu idea on how much data is transferred ?? how long is it running ?? -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
