It seems when drive warms up (heats up) the chuck-cluck disappears. I was able to even mount the drive but trying to dd or tar it results in an I/O-error. While it is cold the FreeBSD ncr driver loops with continuous command failures. But the diagnose that it might have had a head crash seems to me the most probable. Maybe I will be able to recover some data. Thanks anyway for all the interesting advice and stories about temperature drift, CPU fans, and all that :-) > > Peter > > -- > Peter Dufault (dufault@hda.com) Realtime Machine Control and Simulation > HD Associates, Inc.
