I can no see data, no access to secs. and terminal not respose, sometimes respose, sometimes very slow, and sometimes simply not response.

Do you know any way for data recovery?

When happened to me it was PCB or ROM (OUCH!!) other case was HSA.

Thanks Black, I think as you
Then I'll try PCB-ROM. If no way ill try HSA


Thanks
