I'm not sure if it is in your case, but it is worth a try,
The Microsoft guide below will step you through it;
I hope that helps.
Last week my pc shut down, when I tried to boot back up it through me into System Restore. It was set back to factory settings. Lucky I had backed up my pictures which can not be replaced....Today I find that I saved my pics as a read only file.. I can't even open the folder. I was wanting to know if anyone out there could let me know if I could recover these pics or change file on my back up disk????
Anyones help would be an answer to my prayers!
