If one of your disks is broken, you have lost all of your data.
You should reset the drives to non-raid, but you will need to reinstall windows somehow so get a dvd/usb with windows on it.
Alright, well looks like my real problem now is finding a windows disc or ISO. Well, I guess I'm just gonna throw away the bad drive, and leave only one in. Would I HAVE to set up a new RAID0 after getting the said disc, or would I be able to boot from a windows disc/usb and set it up on the working drive and get my computer to work from there?
