When you setup the RAID5 array, what stripe size did you use ? I found problems with anything other than the default 64K. What BIOS rev are you using? The only RAID 5 setup I use is on a 7810. 3dm2 shows Model 7810 Serial Number F11402A2120284 Firmware FE7X 1.05.00.056 BIOS BE7X 1.08.00.046 Monitor ME7X 1.01.00.038 It stores pgp encrypted files that we check once a week to make sure they are OK and I have yet to find any issues. ---Mike
