Re: Grub 2 Issues - was Weird Boot - luv-main

Hi Ed,

Thanks for your efforts on my behalf, I enlisted the support of an 
experienced tech and we were unable to get anything  working. So I shot 
down to MSY and 30 minutes later I had hooked up the SSD with an adapter 
to my laptop. It cannot access the drive. Here is the message:

An error occurred while accessing 'root', the system responded: The 
requested operation has failed: Error mounting /dev/sdc3 at 
/media/andrewlg/root: wrong fs type, bad option, bad superblock on 
/dev/sdc3, missing codepage or helper program, or other error

I think it is stuffed.

Kind regards

Andrew

  Hi Andrew,

 I setup a BTRFS system on a USB key and a "play laptop" and tried to 
 retrieved files using photorec . It works.  I used a copy of gparted 
 iso .  This may yield results for getting your data off sda3 Fingers 
 crossed.

     Hi Andrew,

     I tried installed testdisk, and ran photorec against a USB key (
     not corrupt mind you ) and it seems pretty straightforward. 
     Perhaps you should see if you can get the data off sda3 this way.

         Hi Andrew,

         From an earlier post, Photorec may be the go.  Does the rescue
         disk that you got the output to pastebin have Photorec ?  All
         may not be lost.

         ps. I learn something new everyday ( thanks Bob )- this seems
         to be a tool well worth getting a good understanding of.

             I use grsync. I have a few saved processes, so I just fire
             it up and hit "go".  Each backup is around 10Gb.

             I have a little bit of time up my sleeve but soon the
             pregnant lady will want her special shot.

             Thanks

             Getting slightly off topic here , looks like you copy and
             move files from devices to devices ; Do you do that
             manually or is there a script that does it for you ?

                 You could take it to a commercial Linux org that
                 knows BTFS and get them to rescue /dev/sda3.  It may
                 cost a few hundred dollars but ...

                     Hi Andrew,

                     Silly question from me: do you have a backup of
                     sda ? Can you mount sda readonly ? . Another idea
                     - outside this technical sphere is that perhaps
                     you could ask some commercial Linux support org
                     that may be able to provide support.  Obtaining
                     support from a list ( a very good one at that - I
                     learnt a lot from the posting of this list ) can
                     sometimes be stressful.

                     Sorry I can't offer too much help - I don't know
                     BTFS or RAID , I am a luddite , I only know ext3/4.

                     Hi Ed,
                     I use my SSD for quicker processing and then when
                     my work is done I move the RAW files to my RAID
                     drives and make copy to an external 3TB, my
                     images once exported as proofs and full size
                     images are copied to the RAID drives and Google
                     Drive, and the external hard drive. But I was in
                     the middle of a project when it went down. My RAW
                     files are still on sda3..
                     Bugger. Its a pregnancy shoot, too late now to
                     reshoot.
