Yesterday I cloned my old system disk (250Gb WD) to a new disk of same size and manufacturer, using dd: dd if=/dev/sdb of=/dev/sda The process seemed to go well, but now when I look at dmesg I see the below messages. What do they mean? My old drive doesn't show these. SCSI device sda: 488397168 512-byte hdwr sectors (250059 MB) sda: Write Protect is off sda: Mode Sense: 00 3a 00 00 SCSI device sda: drive cache: write back SCSI device sda: 488397168 512-byte hdwr sectors (250059 MB) sda: Write Protect is off sda: Mode Sense: 00 3a 00 00 SCSI device sda: drive cache: write back ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata3.00: tag 0 cmd 0xb0 Emask 0x1 stat 0x51 err 0x4 (device error) ata3: EH complete ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata3.00: tag 0 cmd 0xb0 Emask 0x1 stat 0x51 err 0x4 (device error) ata3: EH complete ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata3.00: tag 0 cmd 0xb0 Emask 0x1 stat 0x51 err 0x4 (device error) ata3: EH complete ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata3.00: tag 0 cmd 0xb0 Emask 0x1 stat 0x51 err 0x4 (device error) ata3: EH complete ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata3.00: tag 0 cmd 0xb0 Emask 0x1 stat 0x51 err 0x4 (device error) ata3: EH complete ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata3.00: tag 0 cmd 0xb0 Emask 0x1 stat 0x51 err 0x4 (device error) ata3: EH complete I see a similar set of messages for my old IDE hard drive that is also in the computer, but was not involved in the upgrade.
