I've looked through several pages of threads here and have yet to see my exact problem. Built my friend a system early this year consisting of an A7N8X deluxe with 2 WD 37 gig Raptors in a raid 0 configuration. After about 3 months he got the system 32 file missing message and we were able to work around it for a couple days. Eventually I thought he may have actually deleted an application and reinstalled XP. Has worked fine for about 3 months and am getting the same problem again. Ran WD's diagnostics and seems 1 drive may be bad. Does it seem logical that a drive could work for 3 months and still be bad? I may not use the raid array after this. Thanks for helping.
