I have had 6 of these drives in this week, all presented as BSY problem, all had very high reallocated sector counts, all had multiple bad sectors. 2 failed in first 20 minutes of cloning (head 2 errored up, I turned it off, then lost head 3, about 2 minutes later all heads bad and clicking on startup, opened in cleanroom ringed all platters!
This is new 7200.11 problem that we are seeing (actually a combination or other problems).
We are now seeing drives failing very quickly (bad sectors probably from platter surface breaking done due to overheating is my hypothsis).
That rapid failure triggers the BSY bug if not at the first counter trigger at one of the subsequent 256 repeats. Due to the rapid failure mode, the drive triggers BSY quickly.
Using PC3000 to reset BSY, flashing on new firmware, drive normally comes good, viewing smart shows thousands of reallocated sectors.
Start cloning on DDI shows up bad sectors very quickly and the drive deteriorates quickly.
We are now setting up in DE and just ripping the critical stuff via translator, then getting what ever we can.
Watch out for the 7200.11, we no longer just repair and return, we do full Recoveries on them, then recommend warranty replacement.
'ringed platters' means that the head 'touched' the platter?
I always thought that wouldn't be possible, unless the drive stops spinning and the head's hadn't be moved into the landing zone?
Does the drive get so hot that the heads get 'loose'?
I'm mostly asking as my 7200.11 got a bit warm running just in hyperterminal (maybe 10-15deg above room?).. once connected to the sata port it didn't got that warm.. and now it's on it's way to DR. Should I mention this point to them?
