Hi,

Colin's question implies other questions.

Do you mount the drive by using the Mate file manager (GVFS), command
line or something else?

Can you mount the drive at all?

Describe the steps you are doing, when you try to create a folder. What
happens, what do you expect to happen instead? Do you get any warnings
and/or error messages? Are you trying to create a folder by a file
manager or by command line?

If I google for "gtech compact drive" the hits return "Plug and play on
Mac; easily reformatted for Windows".

To share data of a Linux computer and iPadOS I formatted some external
drive partitions with HFS+. After using the drive with iPadOS I always
run fsck.hfsplus on Linux, before doing anything else, since HFS+
support by Linux is broken. APFS isn't supported at all.

IOW what file system are you using? Were the used partition/s formatted
by you?

Apart from running the already mentioned "ls" commands, consider to
open a terminal and to run

 sudo fdisk -l /dev/[...]

or if you don't know what /dev/[...] it is, just run

 sudo fdisk -l

for example

 $ sudo fdisk -l /dev/sdg
 Disk /dev/sdg: 1.82 TiB, 2000398934016 bytes, 3907029168 sectors
 Disk model: 2115            
 Units: sectors of 1 * 512 = 512 bytes
 Sector size (logical/physical): 512 bytes / 512 bytes
 I/O size (minimum/optimal): 512 bytes / 512 bytes
 Disklabel type: dos
 Disk identifier: 0xb568fe80

 Device     Boot      Start        End    Sectors   Size Id Type
 /dev/sdg1             2048 1953517567 1953515520 931.5G 83 Linux
 /dev/sdg2       1953517568 3907028991 1953511424 931.5G af HFS / HFS+

To use HFS or HFS+ you much likely need to install additional packages.
