I recently used hdrecover to repair a disk and it successfully repaired three bad sectors.

How does hdrepair function on raid arrays, is it likely to break the array by repairing sectors?

hdrecover can damage file systems and RAID systems and it should never be used on a production system - on a RAID other than RAID0 it should be completely unnecessary in the first place as you have a working copy of that broken sector on another disk and the RAID will fix this all by itself when you swap the dead disk.

Citing their website:

WARNING: A hard disk with bad blocks on is likely to fail! If you value your data you should get a new hard disk instead of using this program!
