It's better. fast resync 5-6 times successivly, but now,

.....

still a problem ?

md: bind<sda1>
md0: notifying dev 800001 it is now in array
md0: set repair bit to 0 on superblock f7fc8480
md0: md_check_recovery 2: repair bit 0 on sb f7fc8480 preserved

it occurs just one time, and now it's ok again.
