As suggested I have made a few more checks and it would seem that the
system knows all about the device but that it is still unhappy
about applying the TRIM command

[root@paxos:~]$ strace fstrim /media/gtx
...
stat("/media/gtx", {st_mode=S_IFDIR|0777, st_size=4096, ...}) = 0
open("/media/gtx", O_RDONLY)            = 3
ioctl(3, FITRIM, 0x7fffee2fb700)        = -1 EOPNOTSUPP (Operation not supported)
...

Not sure what this is really telling me
