[smartmontools-support] Seagate Backup external USB drive

[James]

I have a Seagate Backup external USB drive that I am trying to get 
smartctl to work on.
ID 0bc2:ac30 Seagate RSS LLC BUP Slim

I found this post from 2014 showing it working but I wouldn't be 
surprised if it uses different parts now.

$ sudo smartctl -i /dev/sda
smartctl 7.2 2020-12-30 r5155 [aarch64-linux-5.13.0-1022-raspi] (local 
build)

Read Device Identity failed: scsi error unsupported field in scsi command

A mandatory SMART command failed: exiting. To continue, add one or more 
'-T permissive' options.


This starts to work:

$ sudo smartctl -d scsi -i /dev/sda
