ok - so I worked out & tried the xfs_repair command:

I'm pretty new to all this so you'll have to walk me through it if possible - how do I check the logs? - Linux ubuntu 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux - xfs_repair version 3.1.9 > > http://xfs.org/index.php/XFS_FAQ#Q:_What_information_should_I_include_when_reporting_a_problem.3F > > > I then tried with a Ubuntu liveCD - same error.

Yes it's a NAS drive and so I assume had some kind of proprietary OS on the other partitions (this is where i might have messed up by deleting?!) I'm pretty sure that the drive in bold below (sdc2) is the one I'm after which is xfs... ubuntu@ubuntu:~$ sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL NAME FSTYPE SIZE MOUNTPOINT LABEL sda 596.2G ├─sda1 vfat 200M EFI ├─sda2 hfsplus 491.8G Macintosh HD ├─sda3 hfsplus 619.9M Recovery HD └─sda4 ntfs 103.6G sdc 931.5G ├─sdc1 1K └─sdc2 xfs 930.6G sr0 iso9660 981M /cdrom Ubuntu 14.04.1 LTS amd64 loop0 squashfs 938.7M /rofs & This: ubuntu@ubuntu:~$ sudo fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'!

Apologies again but you'd have to walk me through the process of exactly what to type in - as I say I'm really not very experienced with Linux/ubuntu & terminal! Cheers!
