This is probably not a FreeBSD-only question, but since I've only tried this with FreeBSD (don't want to let dos infect my hard disks, yet :-)) I wanted to see if any of you have seen this problem before. First, some background... I have a generic P90 clone system with a CMD640 onboard ide controller with two interfaces (both enabled.) On the first ide interface (wdc0) I have a 730meg hd and an atapi cdrom which were factory-installed. The hd is jumpered to be the master and the cdrom is the slave. Both work fine. Recently I received a new 2gig ide hd and attached it to the second ide interface (wdc1) jumpering it as the master. FreeBSD 2.1.5 recognizes all of my hardware: wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (wd0): wd0: 696MB (1427328 sectors), 1416 cyls, 16 heads, 63 S/T, 512 B/S wdc0: unit 1 (atapi): , removable, accel, dma, iordy wdc1 at 0x170-0x177 irq 15 on isa wdc1: unit 0 (wd2): wd2: 1916MB (3924144 sectors), 3893 cyls, 16 heads, 63 S/T, 512 B/S and reading/writing to all of the devices works like a charm (well except for writing to the cdrom of course :-)) I successfully fdisk'ed and disklabel'ed the new disk, and can mount it. _However_, when I try to do something like `cd /mnt/usr (this is the new drive); tar cfvz usr.tar.gz /usr' the whole system just freezes. No panics, nothing. The same thing happens if i do something with the cd for example `dd if=/dev/wcd0c of=/mnt/usr/cdrom.img' Everything freezes. Is my motherboard broken? Would getting a new pci ide controller help? Thanks, -- Jason Garman http://www.nesc.k12.ar.us/~garman/ Student, Eleanor Roosevelt High School garman@phs.k12.ar.us
