Here is the pertinent dmesg section: == BEGIN OUTPUT == hda: IBM-DTLA-307075, ATA DISK drive hdb: IOMEGA ZIP 250 ATAPI, ATAPI FLOPPY drive hdc: KENWOOD CD-ROM UCR-421 V226G, ATAPI CD/DVD-ROM drive hdd: PLEXTOR CD-R PX-W1210A, ATAPI CD/DVD-ROM drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ide1 at 0x170-0x177,0x376 on irq 15 hda: 150136560 sectors (76870 MB) w/1916KiB Cache, CHS=73308/64/32, UDMA(100) Partition check: /dev/ide/host0/bus0/target0/lun0: p1 p2 p3 p4 < p5 p6 p7 p8 p9 p10 p11 > hdb:<3>ide-scsi: hdb: unsupported command in request queue (0) end_request: I/O error, dev 03:40 (hdb), sector 0 unable to read partition table ...
