when you disconnected the disks ... how exactly did you do it
to simulate the ddisk failure ..
- did you pull the power cord or pull the ide cable off
- power up the system with the other disks ..
- write a 2GB file ... in degraded raid mode ...
- power down .. reconnect the cable ... power up
- and watch it resync..
( pull or connect the cables when the power is off )
soemthing whacky if you have to manually add the disk back in
with mdadm ... it thinks its brand new virgin disk ?? vs just needing
to have it's new files sync'd to the disk that just came online
