Ok guys, I have a Sony VGC-RC210G HTPC, it shipped with 2x160GB drives in RAID0 config. Yesterday I got 2 more 160GB drives and I want to add them to my config but can I do this without losing all my current data in the original configuration? I have the Intel Matrix Storage Manager, and checked out the options right after booting, but seems like I'd lose all my data creating a new config. Just need some info. Thanks all.
