If all thge disks were formatted in other drives, it could even be one of
the other drives that actually has the problem.
One of the first tests should be to take a virgin/bulk erased disk, format
it, and WITHOUT unclamping, write and read it. If it reads/writes fine,
then the clamping MIGHT be out of alignment, but is at least stable in its
[wrong?] position. If you still get wobbles, then something is loose and
unstable in its position.
Then unclamp, remove, reinsert, reclamp, and try it.
And, how well do disks formatted in this drive do on other drives?
