Since I wanted to use my external HD usb drive to backup a couple of VMs, I plugged it on my Proxmox machine and I ran:
fdisk -l
	
	
	
		
then:
mkdir /media/external
mount -t ntfs /dev/sdd1 /media/external
I can see now my new usb disk in pve->disks. It's the last one (sdd):

then I go to datacenter->storage and try to add a folder:

But I got this error message:

if I run:
root@pve:/media/external# ls
The directory is there
'$RECYCLE.BIN' BACKPROX FOTOs 'System Volume Information' FILES
What is the problem then?
Thanks
