External drive with ubuntu

[Ralf Mardorf]

PS:

If you are using HFS+ and you should get read/write errors or experience
some other issues when e.g. trying to create a folder, run

 sudo fsck.hfsplus /dev/[...]

or if you know a label, for example (u5.hfs)

 $ sudo fsck.hfsplus $(blkid -Lu5.hfs)
 ** /dev/sdg2
    Executing fsck_hfs (version 540.1-Linux).
 ** Checking non-journaled HFS Plus Volume.
    The volume name is u5.hfs
 ** Checking extents overflow file.
 ** Checking catalog file.
 ** Checking multi-linked files.
 ** Checking catalog hierarchy.
 ** Checking extended attributes file.
 ** Checking volume bitmap.
 ** Checking volume information.
 ** The volume u5.hfs appears to be OK.

After running fsck.hfsplus creating a folder should work.
