i have a little conundrum right now with my RAID array. it says a hard drive is broken, but its operating normally, as far as i can tell.
my info: intel quad-core with intel ICH10R Raid controller
dual 640 Western Digital Caviar Black HD
all about 9 months old now
i run a RAID 0,1 array, using the intel matrix storage manager. i set up the array in the bios, but the manager itself runs through windows. i've got all my important info and my OS on the RAID 1 side (labelled "mirror"), and the programs on the RAID 0 side (labelled "stripe").
when i boot the computer, i am told:
one of my physical drives has an error "error occurred"
my RAID 0 partition is "normal"
my RAID 1 partition is "degraded"
in windows, a box says some data on the RAID 0 partition failed and i should back up.
(this info comes through the intel matrix storage manager when my computer is booting up)
it seems that there is a problem with one of my hard drives, and indeed its probably failed in some way. but everything is working fine. i ran diagnostics through windows 7 and they say my physical hard drives are okay, and i got the diagnostic from Western Digital but that thing was completely screwy - it gave me a cable error on both, which is clearly untrue, and thought my serial numbers were wingdings. the only thing that seems to think i have a problem is the Intel Matrix Storage Manager. plus - if a drive is busted, why isn't RAID 0 partition be degraded (or even failed) as well, instead of normal?
what should i do here? obviously i've backed up everything important, and i feel like i should RMA my hard drive. but it seems like such a pain in the butt (i'll have to reinstall all my programs onto the RAID 0), and right now i am skeptical about how much is really going wrong. i'm using the computer right now, 3d modelling like normal. is there another diagnostic program that is reliable, or a way to simply repair my hard drive?
i'll do this because if i have to, but there has to be something to access my SMART data thats not a new operating system, because i don't currently run ubuntu. if anyone knows of something, i would appreciate it.
