I get the following message to my messages and warn logs about once a second: Dec 4 07:38:08 sambaserver kernel: hdc: packet command error: status=0x51 { DriveReady SeekComplete Error } Dec 4 07:38:08 sambaserver kernel: hdc: packet command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } Dec 4 07:38:08 sambaserver kernel: ide: failed opcode was: unknown Unfortunately, I made too many changes at the same time. My DVD seemed to be broken, so I replaced the device. I was also having problems updating from YOU, so I ran system repair. After the repair, I was able to complete YOU updates.
