18.04 LTS Unmounts external HDD when session locks












0















I have an external HDD I use for backups (rsync during night) and other stuff. On 16.04 it was mounted all the time and I did not have any problems. In 18.04 however, after I lock my session, the disk spins down and gets unmounted.



The mountpoint is /media/username/NameOfDisk and the device is /dev/dm-0



Is there a way to prevent this from happening?



BTW: I tried



sdparm --save --clear=STANDBY /dev/dm-0



and got



unable to access /dev/dm-0, ATA disk?



I also created a cron job that touched a file on the disk every minute, but it still unmounts.
