[smartmontools-support] Is this a bug?

[George R Goffe]

Hi,

I just built smartmontools from the(?) repository.

I have an SIIG 3.0 USB 2x docking station. When I do "smartctl -i /dev/sdb" I get:

fc35-bash 5.1 ~# smartctl -i /dev/sdb
smartctl 7.3 2021-03-02 r5210 [x86_64-linux-5.12.0-0.rc1.162.fc35.x86_64] (local build)

/dev/sdb: Unknown USB bridge [0x152d:0x2551 (0x100)]
Please specify device type with the -d option.

Use smartctl -h to get a usage summary


The disk is:

fc35-bash 5.1 ~# fdisk -l /dev/sdb
Disk /dev/sdb: 465.76 GiB, 500107862016 bytes, 976773168 sectors

When I try smartctl -d scsi  -i I get:

fc35-bash 5.1 ~# smartctl -d scsi -i /dev/sdb

/dev/sda in the laptop produces what I was expecting from /dev/sdb.

Lacks SMART capability? The drive isn't that old. 500gb Seagate laptop drive.

Am I doing something wrong? Is it possible that the SIIG docking station is NOT allowing ALL device commands?

If you could help me with this I would be GREATLY appreciative.

Best regards,

George...
