No, I do however use a desktop with 2 drives.
I have my profile for ArmA 2 OA in my documents, and something doesnt look right about it. However, whenever I try to verify my integrity cache on Steam, it only replaces 1 file. (I am unsure of what that file is).
Profile path to my ArmA 2 OA documents
ArmA 2 OA installation Folder:
D:\Program Files (x86)\Steam\steamapps\common\Arma 2 Operation Arrowhead
