I have lost drives that were setup on RAID 1 through my BIOS. However, each time this occured I had to move the data to another drive and restup the RAID 1 with a working HD.
Note: If I simply plug in a new drive in the same sata port as the failed drive (with the power on or the power off), the BIOS does not recognize the new drive and wants the old failed drive. Thus, I have to delete the RAID setup and resetup with two working drives. The BIOS deletes all the data from the one good drive that was previously setup on RAID which is why I must move all the data first before I do any of this.
My question is: I've heard that you should be able to just plug in a new drive without all this trouble. Is this because the RAID controller on the mobo is crap or am I just an idiot?
P.S. This mobo is not the one on my signature list.

Highly recommend a hardware raid controller instead of use the Mobo RAID...
Although it works but it consumes too much CPU timing -
Example: RAID1 or RAID0 with 2x drives
When Read or Write - Both HDD send IRQ request to CPU, it's double amount of IRQ being send
where a hardware raid controller present to system a SINGEL HDD, therefore read/write requires 1/2 of the IRQ
This is why all the high-performance system uses hardware raid.
