Where did the drives come from and what brand are they? I believe you said 
the drives were a part of a RAID5 Array? If they were a part of a hardware 
RAID5 Array, you may have to put them back in that server, or another 
server with the same RAID controller, and remove the RAID5 configuration. I 
ran into this issue when upgrading 4 PowerEdge servers and using the old 
server's drives and splitting them up. Everything was configured with 
PERC6i controllers in the old servers. The drives failed to configure in 
the newer servers. I ended up putting them back in their original servers, 
backing them up, and used the controller firmware to remove the RAID.
Another way, if you don't need to save the data, is to get the drive 
manufacturer's utility software or possible 3rd party software, and low 
level format and reinitialize the drives back to factory settings. I have 
done this many times, when I run across a stubborn drive that has been pre 
configured and will not allow re-partitioning or formatting.
