Well it's official the RAID system is trashed on my computer. We got it boot up last night, checked the errors and ran a defragmentation scan (31% fragmented files is a lot) it took all night to run that scan and fix the errors. And hope against all hope it started doing it again - the clunking noise in the hard drives. I'll run a diagnostics test on the RAID tomorrow but I already know the results based on it's performace.
The only bright spot in this whole ordeal is the hard drives are half what I paid for them 4 years ago! The down side is I'll have to wait a few weeks to do the repairs as sales have been rather slow of late. I guess this is a sign that I should spend more time dyeing, painting, and stitching fabric! ;-) Now that's a bright spot I can embrace!!!
