Why

If you need GUI-based access to the contents of a hard drive, or if you need to mount an ext2/3 hard drive on a computer running Windows or OS X, this page may have an answer for you. The process outlined here is useful for someone rescuing data from a backup USB hard drive, or from a data partition in a Linkstation.

  • a computer running OS X (10.3-10.4.x are currently supported)

Error messages and their meaning:

  • Invalid argument
mount_ext2: /dev/disk3s1 on /Volumes/linux: Invalid argument

If you are using a USB drive, this may mean that you forgot to unmount before physically disconnecting your cable.

  • No such directory
/dev/disk3s1 on /Volumes/linux: No such file or directory

You may have forgotten to create the mount point directory in /Volumes.
