Okay, you happen to have any knowledge to pass on about current 1tb
disks?
I am still looking for some good 1TiB drives myself. I know one user who has 12 of these, 11 in a RAID-5 array and 1 as a spare on a 12-port 3ware
PCI-X card:
SAMSUNG Spinpoint F1 HD103UJ 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s Hard Drive

I really would like to find a disk with a working NCQ implementation in Linux and 3ware and one that works well. In a single disk configuration, the WD 750G that I have used for ~1 year+ now has been fine, the problem is finding good, reliable disks when used in a raid configuration, that is
when everything changes.

sorry to ask so much, but by "this process", do you mean the drive
internally doing it rewriting, avoiding the kickout, or do you mean the
raid system discovering the disk as faulty, and kicking it? :)
The process being check or repair as noted by mikylie who also responded to
this thread, see his response regarding check vs. repair.  There is a
difference, with check/mdraid see mikylie's note, with RAID VERIFY on a 3ware
controller it will remap bad sectors to others parts of the array as it comes
across them both during RAID VERIFY and while the array is running live.
