not all the time, ive got an arcade thats sitting here, that came back with a new motherboard, and the same benq drive that it had when i reported the 3RRoD, still got the man. date on the back, and the same serial it went away with.
same with my elite that went and came back a few weeks ago, that came back with a new liteon drive(it was a benq, originally), and a new motherboard, and fans.
still got its original serial, and man.date. on the sticker.
and that went away 2 weeks ago this friday,and was redelivered on monday past..
just glad they never stuck the new drive revision in.
But the drives keys are different.
