This is a Linux only box. Put my old Windows data on the second drive with Partition Magic (Fat32), so I know both drives work and are visible under DOS. Installed Mandrake 9.2, went flawlessly except partitioner only saw sda and no sdb. After install, still no way to see second drive. Checked man pages for command line utils and tried querying the system in a number of ways, but it does not know about the second drive.
They're both old IBM caviar drives sda(8gb) sdb(4gb) hooked up to an adaptec 2940UW controller. I shouldn't think the OS would care, doesn't SCSI abstract that? This is the surfing machine for my wife, so it's scrounged parts.
BAck to basics:
Does the controller card see the drive during its BIOS boot scan?
Is the SCSI terminator on the last drive on the ribbon cable?
Does the output of dmesg show anything for sdb?
Does cat /proc/scsi/scsi?

Yes and Yes. Remember, it works if I boot to DOS and it worked in Windoze before I nuked windoze
Does the output of dmesg show anything for sdb?
Does cat /proc/scsi/scsi? [/B][/QUOTE]
I will try those last two. Can't answer til I get home. Anybody else have something I can look at, please chime in...
When the kernel is loading you echo's on the screen, can you see the module for the drive loading? Did you check the system logs? Lets say you try this.
Maybe the BIOS settings for the drive are off enough for linux to say NOPE. Like I said, works under DOS and Windoze but not Linux. This looks the same as bootup time; just finds the first disk and stops looking....
Mandrake 9.2 and no, I can't mount from the command line or see the second drive with any utility. I'm going to go into the SCSI bios and reset the values. It's got to be something there.
Still no luck: The drive is accessible from every other environment (DOS, windows, bios utilities), everything but Linux. If this was a termination or cable problem or driver problem, why would my system run? Linux is on the first SCSI drive!

I'm no expert at this and I don't know Mandrake but I had similar problems with RH9. That is until I repartioned my SCSI drives. When I loaded RH9 the last time (took a few installs to find out where I was messing up) I kept trying to partion and format the drives as something other than ext3 or ext2. I went on to the forums and someone told me to make sure and go ahead and format them as ext3. I was trying to use NTFS. As soon as I did all the above they showed up correctly. I was using Disk Druid during the install. As far as my SCSI bios I just loaded the defaults. One question though what does your screen say during boot up before Linux loads? Does it show the drives being loaded then? Mine did and everything looked like it should be fine but Linux didn't recognise it until I did the correct partion and format. Wish you luck and a happy new year!
Only my main boot drive (sda) is visible at boot time. I tried the scsiadd command to scan for drives and even tried to add it using the device number, but it cannot detect it in the system.

One thing I didn't mention before is that RH9 is very specific about what SCSI controllers you can use. I am not sure about your distro. One thing to check though. I know this may sound rudimentary, but have you checked all of the really basic stuff like cables, terminators, and the like? Where dos and win are somewhat forgiving, they are also loose. Remember that your are trying to use a real OS now and it may not be as forgiving. Start with the basics. I have always found (usually anyway) that it is something really stupid that I did/did not do correctly to make the screw up. Remember that it will only do what you tell it to do. Wish you luck!
