First of all, I want to thank for this wonderful software!
I would like to report a strange behavior of smartctl with USB sticks (I know, it was not born for these units, and perhaps no one has ever tried to use it in this way...): using the "-d ata" option, smartctl return correctly the manufacturer and the firmware version, but indicating that the drive supports SMART technology, although this is not possible.
I've attached the output of three of my USB sticks, I hope this report will help to solve this little issue!
Best regards,
