[Bug 734883] Re: mounting HFS+ volumes fails on large sector devices

[ricardisimo]

I'm having difficulty mounting a 6TB G-Technology external HD.  I believe it is exactly as with the others here:
:~$ dmesg | tail

  Natty Alpha 3

  WIth Natty I only tried now to mount my iPod, but it doesn't work. It
  used to work great under Maverick, though.

  Here's what I get from dmesg:

  [  452.340069] hfs: unable to find HFS+ superblock
  [  452.410078] sd 7:0:0:0: [sdb] Bad block number requested
  [  452.410110] hfs: unable to find HFS+ superblock

  And this is the error message from the GUI dialog:

  Unable to mount 8.1 GB Filesystem

  Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb3,
         missing codepage or helper program, or other error
         In some cases useful info is found in syslog - try
         dmesg | tail  or so
