[Solved] hdparm -I /dev/sda gives me HDIO_DRIVE_CMD(identify) failed

Hello!

As I wanted to find out whether my SSD drive on /dev/sda supports TRIM I used this command as specified in the Wiki:

hdparm -I /dev/sda | grep TRIM

This gives me the following error:

HDIO_DRIVE_CMD(identify) failed: Bad address

What does this mean? There is definitely a /dev/sda in my system and it is mounted.
I checked with df:

- /dev/sda1 is mounted as /
- a subvolume (it's Btrfs) is mounted as /home

Any ideas?

Confused,
piedro

Well, a newbie question with a simple answer...:

The command works fine and verifies my Trim support easily if used as root (per "sudo").
It's not designated as "run as root" in the arch wiki so I haven't thought about that...

Solved, I guess...

thx anyway,
