I bought a SSD to upgrade my laptop. And removed the HDD and putting it in a caddy to replace the DVD. I would like to use this configuration to backup my system to the HDD. I have a laptop called Lenovo T540p.

The issue is here: de HDD disappears after a pm-suspend. It s totally gone and spinning.

What is the best way to investigate? Any tips are welcome!

Regards, Marco

P.S. some info

- Using CRUX 3.4, fully updated.

- on boot the HDD (sdb) is detected.
