[Google-Desktop] Desktop will not index RAID 1 drive(s)

My system is set-up RAID 1 (mirrored). Combined, the mirrored drives
(combined) are labeled Local Drive F.

I also have another internal drive installed, labeled Local Drive E.

The F: drive(s) contains the OS (Win XP Pro SP2) and most of the data I
would want Google Desktop to index.

The E: drive contains only image files. (.jpgs, .tif's, etc.)

Google Desktop will not / can not seem to index my F: drive(s).

I get the error "Unknown error trying to access files during crawling".

Any suggestions would be greatly appreciated!
