I got strange problems with my 6100 backup machine last night. One of the two SCSI HDs (IBM DDYS-T18350, 18 GB, 10k rpm) went into an self induced shutdown. Then i got an error message stating that information on drive XY was altered and maybe lost (OS 8.1). After a short period the drive started spinning up and the data was still accessable. What is happening here, Is there any diagosis tool to read out the failure info from the disk?
