Well don't do that!

Mount under /usr/backup, or /var/backup, or /tmp/backup or whatever!

Is this due to my ancient HW, crappy USB controller card, or is USB mounted disks just less stable?

Even if the externally powered USB disk never fails, still there is the chance that the two independently power supplied boxes get out of sync, for instance in the event of a power cycle... You power cycle both of them: do they come back again in time to pick each other? (I have a machine with a USB disk where this NEVER happens, when the bootstrapping OS tries to mount the USB disk, the disk is always spinning up or whatever but it's not ready yet so the mount fails)
