Restoring an XFS partition, Restoring an XFS partition Options

[gvoyzey]

Hi Guys

Any help here would be greatly appreciated.

Occasionally I need to restore files from dead Lacie NAS drives. We use them for network storage devices on a home networks for Sonos music systems. I've had so many faulty Lacie drives over the last 3 years I lost count.
I believe that Lacie NAS drives store files using an XFS partition format. The partitions are not accessible from windows or OS X, so I've installed Ubuntu via VM ware and I can happily view all the partitions on the NAS drive (once the HDD is removed from the NAS enclosure and placed in a USB cradle).

The problem is that some files are locked and I don't have permission to move, copy or even open the folders. Now, I think I've really stuffed it by using trying to change the permissions via the info I could gather from the net.
I used the "sudo chown 666 /media" command in the terminal (/media is the folder where over 500 Artist & Album folders are stored, 450 of which are locked)

Now the drive partition has disappeared and won't re-mount after a restart. All I need to do is find the partition again and unlock all of the folders so I can copy them to a new HDD (assuming I haven't trashed them).

Regards
Glenn

Here it is...

The 500GB partition is the partition where the music folders were stored...

The partition table is a bit odd. I assume the data is in sdf2.
/dev/sdf2 126 60801 487379970 83 Linux

It is not automatically mounted then try manually.
mount -t xfs /dev/sdf2 /media/mount_point (Create a directory as desired)

That's it! Hooray!

Thanks for taking time to help a newbie like myself.

I appreciate it.
