And if you get read errors, well, aiui, raid won't help here either - especially with mirrored raid, you just get a read failure. Raid does NOT give you error recovery unless the drive physically fails, and if it's a bad block it gets fixed at the disk or disk driver level - well below the raid driver.
You're wrong. In case of a read error from the physical drive on RAID1, RAID5 or RAID6 then the information will be re-created from another drive, and written to the drive that threw a read error. This is the whole point of RAID with parity information.
