mounting an external USB3 drive

[lloyd]

I am using Mageia 9 Final.

I have two Western Digital external USB3 drives. They are not used simultaneously. One of the drives mounts normally when connected to a USB3 port. The other drive does not. A message comes up that says, "you are not authorized to mount this device>' So, I switched to root and tried it again. The same error message showed up. However, it DOES work normally if I connect it to a USB2 port. Could this have something to do with the name of the drive? They are both "My Book." Mounting the "bad drive on a USB2 port shows it as "My Book 1." Is this what's causing this error?

Mostly, I'm just curious....

Thank you.

It depends on the content, and the connection. E.g. if there's any filesystem with posix permissions, then you usually need to mount it as root.
Or if the filesystem is marked as dirty and needs an fsck. Or if it's an internal drive or recognised as such (quite some time ago e.g. external eSATA drives were recognised as internal drives as they basically had a SATA connection).

Although you don't mention at all what filesystem is on those two disks, and what desktop environment your're using, as mount helpers might behave differently.

You'd need to query the disks via udevinfo and maybe also udisks like so, if the disk/partition would be /dev/sdc1

Code: Select all

udevadm info --attribute-walk --path /dev/sdc1
udisksctl dump
