Milestone: undecided

Option -d sat,auto does not detect SAT support of USB drives because these never return "ATA " as SCSI VENDOR string. Please try -d sat or -d sat,12.

comment:2 Changed 17 months ago by Pro Backup

-d sat looks less promising:

# smartctl --all -T verypermissive -d sat /dev/sda

note: Strange to suggest a user to try option -s with argument 'on' when the user has already supplied that option.

Yes, this (very old) message is not suitable for this corner case.

This is a USB flash drive. These devices do not support ATA SMART.

Various other devices with same USB ID exist, see http://usbspeed.nirsoft.net/?vid=9917&pid=39191.
