raid1 mirror optimizations

hi guys... i have a damaged disk...
i´m using raid1
the computer crashed with the floor :P hihiih sorry, but the disks are
damaged at the same position
check: http://www.spadim.com.br/hd%20agra.zip
the problem: since raid1 (mirror) is done with real mirror, the disk
position are the same...
if i was using a mirror but on disk 1 i write from beggining to end,
and disk 2 from end to beggining , i don´t crash the disk at the same
position, for disk 1 i crash it some bytes, for disk 2 i crash some
others bytes, since beggining is a small cilinder and end a bigger, i
could loose less information than mirror
could we implement a 'inverted' mirror? just for hard disks (for ssd
it´s a small loss of cpu/memory)
thanks
