Im validating my raid spot

Check if you're using AHCI mode by viewing the list of controller drivers. Btw, there are two places at my bios that I can change from IDE to AHCI, at the Onboard SATA6G Controller it was already AHCI, but at Storage configuration / Configure SATA as: was IDE, after I change it to AHCI, Windows did not boot!

I have a hand-me-down server that I'm setting up at home and it's got 6 72Gb hard disks (as well as 2 18Gb drives that I'm using for the OS). Should I RAID 5 or 6, or go with something simpler, like mirroring? You don't say how you will be implementing RAID. Is pretty tried and proven and I've always had good experiences when trying to rebuild or recover from it.

I'm planning to use it to hold a source control repository, and possibly data for a development SQL server. Its going to depend a lot on how much space you need, how much speed you need, etc.

EDIT Just a quick reword of my original question...

The choice is totally up to you as to whether you want the extra parity drive or not. :-) Good call on the "depends", but RAID 5 is tried and slowly being disproven. It's more a problem with larger disks, but smaller older disks (like these) is tempting fate as well. He's not dealing with six 500GB or 1TB drives here. If he'd have said he's hosting in a production environment with a brand new server and huge drives my answer would have been different.

My original question: My PC is now a few years old. Consequently I have drives C, E, F, G, and H visible.

When I had it built I had a couple of drives set up as RAID 1 - I also had a few older drives that had my photos/music etc. I know I have my system on RAID 1, but I can't for the life of me remember how the others are set up and which (if any) of my other drives (be they actual drives or just partitions) are also RAID.

If you install Windows with AHCI on then, surely, imaging the device to an SSD will have no ill effects??
