That's strange. According to the output of fdisk he posted, the partition types were identified as 5, 82 and 83 (ext, swap & linux). On my raid system, I have type=fd which is linux raid auto. Was it a bios setting that FC12 was interpreting differently than FC8?<br>
<br>I ran into a big snag a while ago trying to reuse drives that had been in another raid and the darn system kept trying to start the raids on those devices while I was trying to add them to a new system. Recreating the partition tables didn't seem to help, possibly because I was using the exact same sizes so it kept finding a valid raid signature. IIRC, I had to zero out the beginning of the partitions before I could proceed.<br>

I was going to wait for Matt to reply, but basically he ended up<br>
trying the nodmraid kernel option, and that seems to have gotten his<br>
drive to probe properly.<br>
<br>
This suggests that dmraid identified sdc as part of a raidset (even<br>
though Matt had never used the disk in one), so the kernel froze out<br>
the partition-numbered devices for some bogus safety concern.<br>
<br>
I don't believe udev is used to create /dev/sd* devices, just to alias<br>
them to other names, at least in Fedora.<br>
