This usually does not indicate disk problems. Either these logs are not 
supported or this is a limitation of some software layer (e.g. SCSI ATA 
Translation) between smartctl and disk. Did you connect this drive via 
USB? If yes, which USB Id?

Note that "smartctl -a" does not print newer ATA logs . Try "smartctl -x".
