ES.2 Barracuda Moose, LED 0xCC, repeatedly recallibrating

Hi there,

I've successfully restored many 7200.11/12 drives with the LED 0xCC problem, but this drive is different. It is a 7200.11 ES.2, with locked terminal access -so the tweezers methods can be used-, but as soon as it spins up, it enters an endless loop of recallibration attempts, one every 2 or 3 seconds (upon startup, terminal starts giving LED:000000CC errors). Between each recallibration, having the tweezers on the differential read channel, the terminal spits out some F3 T> on CTRL+Z, but as soon as it recallibrates again, another LED:000000CC is shown and the terminal is locked again. PCB replacement was performed using common methods.

Any ideas what may this drive suffer from?

Thanks
