External USB Disk SMART report?

[Phoenix Down]

I know that many external USB Disk controllers are able to pass on the necessary ATA commands to make SMART work. Smartmontools has some good info on this:

 

https://www.smartmontools.org/wiki/USB

https://www.smartmontools.org/wiki/Supported_USB-Devices

 

So theoretically, for supported controllers at least, you should be able to get the SMART data.

 

Does anyone know if Unraid will show SMART reports for external USB Disk?

Yes, but not all controller/bridge.

Smartmontools has a list of supported USB hard drives (link in my original post). Can I assume that Unraid's supported devices list is similar?

I don't think so, because I have two different 5 bays USB enclosure, both can't passthrough SMART info. in first ( I haven't try set to SAT-auto-12 or SAT-auto-16 in that time, unraid just show you may try "-d sat" ).

 

One of them after flash another firmware, then Unraid can read SMART info. in default perfectly , PID and VID also change. Non-multi bay USB bridge should be another story, most could passthrough SMART info.

Ah I was thinking more about single drives. Totally anecdotal, but I have a WD My Passport Ultra 1TB on hand (which is on Smartmontools' supported list) and Unraid is able to read its SMART info.
