Hi Z ;)

Nope, you don't have to (re)install Windows to add a third drive, this is all done by using Disk manager within Windows > right click on My Computer, and select the proper value (Administrate) - or go to the "run" menu and type: MSC, and then select Disk Manager.

If this is still completely blank to you, it might be a good idea to invite 
your favorite computer geek over for a couple of beers.

As a rule-of-thumb, it is NOT a good idea to save important files on a RAID0 array, as a RAID0 array WILL go down, and this usually happens at the most inconveniant time (bin there, and all that stuff).

If your question is more towards about adding a third disk to an already existing RAID array, this can be done, of course. Only you should care that RAID0 works at it's optimum at 2, 4, 8, 16, 32, etc. disks. Therefore, adding an odd number of disks seems quite, well... odd. Hence, forget about using three disks in a RAID0 array. Performancewise, you'll only get a tiny fraction worth of your investment. I've done plenty benchmarking confirming this, and I'm sure other HWG's has done the same - it's just not worth it.

Solution: Go double 4 disk RAID0 by HW controller, and mirror those two arrays 
within Disk Manager as RAID1. The other thing is just a waste of time...

I have a two drive RAID 0 array which is working well for me so far. I have purchased another identical drive from Ebay and it should be here early next week. Am I correct in assuming that I will have to re-install Windows when I add my third drive?
