I get a permission error trying to find the filesystem type of a block device:
$ file -s /dev/sdd1 /dev/sdd1: no read permission
However, If I open gnome-disks, it will happily tell me info all the info about /dev/sdd1 that I want. I checked that gnome-disks is running as my user which does not have read access to /dev/sdd1. So my question is:
How can I find the filesystem type of /dev/sdd1 without read permission to the device?
