Raid 5 problem in array 3

I just went into "view Drive Assignments and it said for Drive mode 3 and then go down to number 3 and under "Assigment" it says LD 3-3 ON all the other drives it says under the "Assigment" it says SINGLE DISK.
So is this a bad hard drive?

I just tried using F8 and what came up was showing was the RAID 4 drives, What one would i chose to boot up in 1-2-3-4 I didn't do anything.

just found out what caused it. My wife while starting the computer and when it was booting up she touched some keys on the key board by accident.Don't know what keys.

Well we got most of the data recovered with some software off the net, cost 40 dollars. some companies wanted from 2 to 4 thousand dollars.
Now im looking at the back up machine called Drobo back up. Any one use it. Or im going to go with 4HD and use it as JOBOD. I have tried raid 5 once and that was ok Did have a hd break and replaced it and everything was fine, and raid 10 and that was the worst, almost lost every thing.
good luck to all
