While that might sound weird, NTFS is a perfectly decent filesystem and Linux can handle it with no problem. Cross platform support is also excellent so you'll have no issues with r/w access on Windows (obviously) and r/o support on Mac OS (unless you install proper drivers from Paragon or whoever). As long as you have ntfs-3g installed then your system will just take care of everything for you and you won't have to worry about permissions and other weirdness. For example, I have a 16Gb NTFS formatted Windows USB installer drive lying around, so I plug it in: ghost@failbot:~$ mount | grep USB /dev/sde1 on /media/ghost/Windows USB type fuseblk (rw,nosuid,nodev,allow_other,default_permissions,blksize=4096) I did nothing whatsoever to enable this - no fstab entries (you shouldn't need them for mounting USB devices in 2014!) or special procedures required, works 100% of the time on any random machine I add it to. In your case, you need to go brute force mode Neil: sudo chown -Rv neil:neil /media/neil/usb-device Where "neil" is presumed to be your username and the path should be changed to wherever your device is getting mounted. Or umount it, and mount it again manually wherever you like. Either way, 'touch /path/to/usb-device/hello.world' afterwards should create the file for you in the root of your thumbdrive without complaints.
