Taking the thread further. A couple days ago, I removed the smartmontools package. I suspected that that may be causing trouble. For the last couple days, my klog was clean and I was tempted to report. But just now, I got a more enhanced scsi error, this time. Does it suggest bad sectors ? Thomas: In the last responses, you asked if there was any Sense key. This time, I do have them.
