This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant.

If you're using SCSI disks then it's /dev/sdx
Try:
hdparm -i /dev/sda
hdparm -i /dev/sdb
etc...
and see what it tells you about your drives

sounds to me like your SCSI card isn't recognized by the kernel so the drives aren't being found.
what linux ditribution are you trying to install, and what kernel does it have?
and what SCSI card do you have?

ah gentoo the next best thing since windoze.
sorry but i have no clue what kernel they use.
if you boot with their live cd and it can't find your drives, my assumption is you should go to www.gentoo.org and post on their forum, unless someone else here has a clue. |

Look at the dmesg output, ie run "dmesg | less" or "dmesg | more" from a command prompt, and see if the kernel is seeing and intializing your SCSI controller and drives. If it's not then the kernel most likely doesn't have the right drivers for the SCSI card compiled into it. So you'd need a kernel that does or else provide them as modules.
