Windows 7: Accidental RAID1 formation, need to restore without file loss

Accidental RAID1 formation, need to restore without file loss

I am using a custom-built computer running Windows7 Ultimate x64 with two harddrives. Previously, these two were connected by RAID0, with the larger drive (1TB) being the primary boot drive and the smaller drive (256GB) drive being the secondary boot drive.

I shut my computer down while booting from a flashdrive, and for some reason, this degraded the primary drive. After removing the flashdrive, on the next startup, it booted to the secondary drive. After restarting my computer and entering bios, the system explained that my primary drive was degraded, and asked me if I wished to "rebuild". I hit "yes", but then the system began rebuilding into a RAID1 system instead - mirroring the data on the smaller drive, which means deleting all the data I had on the larger drive.

It still has the status of the raid volume as "rebuild", which makes me suspect there is still hope. Does anyone know how I can return to my old arrangement and not lose my data?

Thanks in advance!
