 There are several Mac and OSX users in the department. As such it is common that some people may have a Mac external hard-drive. These are usually formatted as hfsplus and are usually "journaled". A drive that is "journaled" keeps a change log. Usually these are **NOT** compatible with Linux or MS environments as its the Mac OSX which is tracking changes to this external drive.
-We are able to mount these drives, **HOWEVER** they will be mounted as read-only. Root (accessible by the Sys Admins - Jon and Zach) are able to force these drive to mount as read-write, **HOWEVER** this comes with a non-zero risk of data loss. Since the drive is keeping a change-log via Mac OSX, if a different OS makes changes to it, there is a possibility that the change-log / data will be corrupted.

+Sometimes it is possible to turn off this "journal" feature.
