I have these hard drives, 2x160GB set as RAID 0, an 80GB that so far has been used only for a scratch disc, and an external 60GB used to automatically back up documents and pictures. I am running XP Media Edition and want to install both Vista and a Linux OS with the OS I now have. Could I, for example, partition the 80GB drive so as to have a 40GB (for scratch drive) and 2x20GB (one for each additional OS) partitions? Would I be able to run the programs on my main (the Raid drive) using either or both of the newly installed OS? Thanks in advance for any advice.
