Thanks for the reply. Should I be using a different version/release that would work better for RAID? If so, pls let me know. As far as your info requests, see below.
thanks.

OK, so RAID support is in the kernel and you've got the required modules loaded. What about your IDE drive? IIRC, you arn't using one of the kernels with IDE built-in, and it doesn't look like you're loading any IDE modules based on the above.
Can you access the low-level /dev/hdX devices that make up your RAID?
What does "fdisk -l /dev/hdc" and "fdisk -l /dev/hdd" show?
Are you *REALLY* trying to build a RAID5 device with two partitions on the same drive (/dev/hdd1 & /dev/hdd2 in your example raidtab, which go along with /dev/hdc1)? If so, I'm not sure that will work, and it wouldn't be recommended in any case...
# fdisk -l /dev/hdc
Disk /dev/hdc: 16 heads, 63 sectors, 8374 cylinders Units = cylinders of 1008 * 512 bytes
Device Boot Start End Blocks Id System /dev/hdc1 1 6242 3145936+ 83 Linux native
toaster: -root- # fdisk -l /dev/hdd
Disk /dev/hdd: 255 heads, 63 sectors, 977 cylinders Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System /dev/hdd1 1 392 3148708+ 83 Linux native /dev/hdd2 393 784 3148740 83 Linux native
As far as my raid5 device, I just want to make sure I can get the raid5 working before I buy a 3rd drive. My test set is 1 4gb drive (hdc) and an 8gb drive (hdb). I created 3 partitions each +3072M on the two devices and am trying to build the raid5 test. I also tried to do this with just doing raid1 on /dev/hdc1 and /dev/hdd1 and got the same error on the same command.
OK, you've got raid support in the kernel, and IDE support is working.
There's not a lot else that needs to be there for RAID to work. Did you remember to make the raid devices (ie: does /dev/md0 exist)?
<excerpt http://lrp.steinkuehler.net/Documentation/LRPHardDiskHOWTO.txt> Check to make sure the /dev directory contains all the devices you need for your hardware. You may also need to update /var/lib/lrpkg/root.dev.mk to create additional device nodes. I added the following lines on my system to support the newly added RAID functionality:
# RAID Devices makedevs md b 9 0 0 15 >null 2>&1 </excerpt>
