I recently tried getting smart status for my WD My Passport USB hard drive. I first ran $ smartctl -a /dev/disk3
but clearly the output was bound to be:
smartctl 7.2 2020-12-30 r5155 [Darwin 18.7.0 x86_64] (local build)

Smartctl open device: /dev/disk3 failed: Operation not supported by device
I checked smartmontools wiki to find instructions about its usage with USB hard drives and found out you have to add -d
with the correct driver, in my case it's -d sat
. Unfortunately the output of the correct command on macOS Mojave is:
$ smartctl -d sat -a /dev/disk3
smartctl 7.2 2020-12-30 r5155 [Darwin 18.7.0 x86_64] (local build)

/dev/disk3: Type 'sat+...': Not a device of type 'scsi'
=======> VALID ARGUMENTS ARE: ata, scsi[+TYPE], nvme[,NSID], sat[,auto][,N][+TYPE],usbcypress[,X], usbjmicron[,p][,x][,N], usbprolific, usbsunplus, sntjmicron[,NSID], sntrealtek, intelliprop,N[+TYPE], jmb39x[-q],N[,sLBA][,force][+TYPE], jms56x,N[,sLBA][,force][+TYPE], auto, test <=======
Use smartctl -h to get a usage summary
Am I doing something wrong? I noticed everyone else is getting the correct output with the same command.
Thanks in advance.
