I am having a problem with my Samsung Micro SD card (in particular, a Samsung 32GB Evo mircoSDHC UHS-1 Grade I Class 10 Card).
I use the card in my 8GB Motorola Moto G 4G which is running Android 5.1. Unfortunately the card recently stopped working, and I am not sure why. I bought both in June.
One day I simply noticed that the card was no longer mounted to the phone. I am now unable to mount the card onto the phone. There is data stored on the card that I would very much like to recover before I format the card.
My computer is running Ubuntu 14.04.3 LTS, and I figure that it will be easier to recover the data on my computer than on the phone itself.
My monitor (Dell, I don't know the model) has a card reader, in particular a Standard Microsystems Corp. 9-in-2 Card Reader (and the Micro SD card came with an SD adapter). The card reader is found by my machine when I run lsusb.
When I insert the card (in it's adaptor) into the Card Reader it is not detected by my machine.
(I have a laptop which runs Windows, and when I insert the card into the card reader on that, it is found by Windows, but I cannot open the device to see what files are on the card).
I have tried searching for answers to my problem already, but I have not found exactly what I am looking for.
I found these similar questions, but the former was too technical for me (I tried to read the documentation attached, but I am not an expert, and my machine is owned by the university, so I did not want to run anything without being sure of what it is doing and that it is safe), while the later assumed that the files have already been deleted.
I also found this info on GUN ddrescue, which may help me to recover the files, once I can detect the card.
Ideally what I am asking for is a way to force ubuntu to read the card, and to copy any files on the card that it can to my machine as a back-up.
I would then be able to format the card, and start over, and hopefully it would be read by my phone again.
For the record, I am trying to recover image files (personal photos which I would like back) and audio files (recordings of work meetings which I need back).
And before Captain Hindsight mentions it, I did back up (some of) my data once in the past 6 months, on the 18th November, but obviously I don't do it frequently enough (and I didn't back up the photos)!
Thank you very much!
