I have 10.9.4 with a usb external (2tb) disk, formatted with Macos Journalled format. The drive is also a time-machine destination.
I am:
- unable to cmd-drag files to move them to another disk (they copy)
- unable to select multiple files and create a new folder from the selection
- unable to mkdir on the drive
TimsMacBookAir:~ tim$ cd /Volumes/2TB/ TimsMacBookAir:2TB tim$ mkdir test mkdir: test: Permission denied
I'm guessing there's permission errors. Here's the ls -l on /Volumes
TimsMacBookAir:Volumes tim$ ls -l total 72 drwxrwxr-x 37 tim staff 1326 7 Jul 10:19 1TB drwxrwxr-x 319 root wheel 10914 7 Jul 10:51 2TB lrwxr-xr-x 1 root admin 1 1 Jul 14:20 Macintosh HD -> /
I'm guessing that since the drive is owned by "root" and group "wheel" that is the issue. What does it mean? Can I just chown -R tim:staff it without stuffing anything up (e.g. my Time Machine backups)?

This might be a silly question but are you sure that the drive is mounted read-write.
From memory, if you type in "mount" in a Terminal it should tell you if the drive is mounted read-only as one of the properties in brackets after the drive. Or you could right-click the drive in the Finder and choose Get Info from the context menu and check "Sharing & Permissions" at the bottom of the Info window. I think it'll tell you there if the drive is mounted read-only.
