Hi, I installed a FC4 box, and tried to use smartctl to show disk parameters on SATA drives, or SATA drives connected through 3Ware RAID5 card, but neither works, my smartctl version is 5.33. my kernel is 2.6.15-1.1831_FC4smp. I added two "-T permissive" but still no luck. Any suggestion are greatly appreciated. Thanks.

To continue, add one or more '-T permissive' options. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
