dell 2850 with perc 4e/di ..can't format drive

when ever I create an array, when i try to install centos and it trys to format the drive and it gets stuck at 27%. Is it a problem with 256 meg cache? I tried various combination but no luck. if I switch to SCSI, I do not have any problem. I can format the drive and I can install the OS. The perc bios says the battery is good. I have latest version of bios is loaded on the system and on the raid controller. 


Can somebody help me with this issue?
