Both drives -- wd0 and wd1 -- are certainly configured in the dmesg you have posted here. I am going to take a wild guess and assume you've swapped channels when you connected the drives, and wd0 and wd1have reversed. Note the size difference of the two drives, and that wd0 is the larger:
Code:
wd0 at pciide0 channel 0 drive 0: <SAMSUNG SV1204H>
wd0: 16-sector PIO, LBA, 114498MB, 234493056 sectors
wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 5
wd1 at pciide0 channel 1 drive 0: <IBM-DPTA-371360>
wd1: 16-sector PIO, LBA, 13042MB, 26712000 sectors
wd1(pciide0:1:0): using PIO mode 4, Ultra-DMA mode 4
And look which drive you used for booting:
Code:
root on wd1a swap on wd1b dump on wd1b
Either swap IDE connections, or edit /etc/fstab while in single user mode and change drive numbers.
