Both my hard drive and the cdrom are being recognized as unit 0.

I noticed that if I did this command repeatedly :
mount_cd9660 /dev/wcd0c /mnt
That sometimes I would get - device not configured.
other times I would get - input/output error.
finally the hard drive light would stay on, and the disk would be unaccessable.

Is the fact that they are both using unit 0 significant?

Here is what my kernel config looks like:

controller      wdc0    at isa? port "IO_WD1" bio irq 14 vector wdintr
disk            wd0     at wdc0 drive 0
disk            wd1     at wdc0 drive 1

controller      wdc1    at isa? port "IO_WD2" bio irq 15 vector wdintr
disk            wd2     at wdc1 drive 0
disk            wd3     at wdc1 drive 1

options         ATAPI   #Enable ATAPI support for IDE bus
device          wcd0    #IDE CD-ROM                             

Any help would be appreciated.
