There > is no way to do it under Linux without a hardware RAID controller? Ok. You are being inconsistent. Either this is _hardware_ RAID (in which case the OS has little to nothing to do with the issue - you need to go into your BIOS interfaces and 'un'-RAID the drives) or it is _software_ RAID - in which case you just need to reformat the drives. You said before it was _hardware_ RAID. Windows or Linux makes no difference to hardware RAID. Now you are implying you don't have a RAID controller - which implies you are using _software_ RAID. So which is it? Software or Hardware? You've implied that you are running RAID0 (2x40GB -> 1x80GB). If that is true, you can probably break the RAID by simply physically *disconnecting* one of the drives before you start installing. One way or another that will disrupt a RAID0 array. -- Benjamin Franz "It is moronic to predict without first establishing an error rate for a prediction and keeping track of one’s past record of accuracy." -- Nassim Nicholas Taleb, Fooled By Randomness
