Need some help with lost data on external drive

Hi all,

I would really appreciate some assistance with some lost data on external drive. The external is a Seagate Goflex 3TB drive, Desktop hard drive | External Desktop hard drives | FreeAgent | GoFlex Desk | Seagate

The purpose of the drive is to do time machine backups to it from my mac. I also have three folders on the drive (software, movies and computer training stuff). Those are supposed to be backed up to the cloud to my crash plan account. But they aren't there; that's another story. I'm kicking myself now, because I know better.

The drive has been making some weird noises lately. It is still under warranty for another month or so, luckily. I have started the RMA process. They are shipping me a new drive, and once I get it I will ship the old one back to them. In the meantime, I need to get my stuff off that drive to another one to restore.

The drive is encrypted with file vault. So it won't allow me to mount it on a Windows system. My neighbor is a Mac guy too, so I sent him a message asking him if I can mount the drive on his system in order to see if I can see the files on his system.

As you can see from the output, there is definitely data on it, since about 26% is being used.

Code:
$ df -h /Volumes/Data/
Filesystem Size Used Avail Capacity iused ifree %iused Mounted on
/dev/disk4 2.7Ti 724Gi 2.0Ti 26% 94949497 271238073 26% /Volumes/Data

This shows the directories:
Code:
$ ls /Volumes/Data/
Backups.backupdb	Movies	 tmbootpicker.efi
Computer_Training	Software

This is showing the size of what's in the directories:
Code:
$ for j in `ls /Volumes/Data/`; do du -sh /Volumes/Data/$j; done
16K	/Volumes/Data/.DS_Store
168K	/Volumes/Data/.DocumentRevisions-V100
1.3M	/Volumes/Data/.Spotlight-V100
0B	/Volumes/Data/.TemporaryItems
0B	/Volumes/Data/.Trashes
920K	/Volumes/Data/.VolumeIcon.icns
8.0K	/Volumes/Data/.disk_label
8.0K	/Volumes/Data/.disk_label_2x
8.0K	/Volumes/Data/.fseventsd
8.0K	/Volumes/Data/Backups.backupdb
692M	/Volumes/Data/Computer_Training
0B	/Volumes/Data/Movies
0B	/Volumes/Data/Software
120K	/Volumes/Data/tmbootpicker.efi

So you can see that all of the above doesn't equal to the 724GB that is being used.

Am I missing something? Can anyone offer any assistance?

diskseekd(1)						      General Commands Manual						      diskseekd(1)

Name
       diskseek, diskseekd - disk seek daemon; simulates Messy Dos' drive cleaning effect

Note
       This  manpage has been automatically generated from fdutils's texinfo documentation.  However, this process is only approximative, and some
       items, such as cross-references, footnotes and indices are lost in this translation process.  Indeed, these items have no appropriate  rep-
       resentation  in	the  manpage  format.  Moreover, only the items specific to each command have been translated, and the general information
       about fdutils has been dropped in the manpage version.  Thus I strongly advise you to use the original texinfo doc.

       *      To generate a printable copy from the texinfo doc, run the following commands:

		     ./configure; make dvi; dvips fdutils.dvi

       *      To generate a HTML copy,	run:

		     ./configure; make html

	      A pre-made HTML can be found at: `http://www.tux.org/pub/knaff/fdutils'

       *      To generate an info copy (browsable using emacs' info mode), run:

		     ./configure; make info

       The texinfo doc looks most pretty when printed or as HTML.  Indeed, in the info version certain examples are difficult to read due  to  the
       quoting conventions used in info.

Description
       Several	people	have  noticed that Linux has a bad tendency of killing floppy drives. These failures remained completely mysterious, until
       somebody noticed that they were due to huge layers of dust accumulating in the floppy drives. This cannot happen under Messy  Dos,  because
       this  excuse  for  an  operating system is so unstable that it crashes roughly every 20 minutes (actually less if you are running Windows).
       When rebooting, the BIOS seeks the drive, and by doing this, it shakes the dust out of the drive mechanism. diskseekd simulates this effect
       by seeking the drive periodically.  If it is called as diskseek, the drive is sought only once.

Options
       The syntax for diskseekd is as follows:

	  diskseekd [-d drive] [-i interval] [-p pidfile]

       -d drive
	      Selects the drive to seek.  By default, drive 0 (`/dev/fd0') is sought.

       -i interval
	      Selects the cleaning interval, in seconds.  If the interval is 0, a single seek is done. This is useful when calling diskseek from a
	      crontab.	The default is 1000 seconds (about 16 minutes) for diskseekd and 0 for diskseek.

       -p pidfile
	      Stores the process id of the diskseekd daemon into pidfile instead of the default `/var/run/diskseekd.pid'.

Bugs
       1.     Other aspects of Messy Dos' flakiness are not simulated.

       2.     This section lacks a few smileys.
