I'm trying to set up a USB disk on FreeBSD 4.9 and having some trouble. it is apparently recognized by the OS, but when I try to do anything with it, it spews a whole bunch of errors: fdisk /dev/da0 fdisk: can't open device /dev/da0 fdisk: cannot open disk /dev/da0: Input/output error ponic# Jul 14 17:25:33 ponic /kernel: (da0:umass-sim0:0:0:0): READ(06).

I rebooted the machine. I made sure usbd was running. What else is there to do? There is nothing particularly special about this disk. This is how it is recognized in dmesg (followed immediately by a duplicate of the above errors): umass0: Prolific Technology Inc. Mass Storage Device, rev 2.00/1.00, addr 2 da0 at umass-sim0 bus 0 target 0 lun 0 da0: <WDC WD25 00JB-22FUA0 15.0> Fixed Direct Access SCSI-0 device da0: 650KB/s transfers da0: 238475MB (488397169 512 byte sectors: 64H 32S/T 41867C) It is actually a Western Digital 250GB 7200rpm PATA hard drive in a "Metal Gear Box" Firewire/USB 2.0 enclosure.
