I have a 64GB Micro SD card that I have been using on a GoPro Hero 3. After momentarily using it in conjunction with an android phone to take a picture, I tried using it in reader again to find that the file system was no longer recognised by Windows 8.
In a dumb panic I decided to use iCare Data Recovery Software in order to format and recover the files with a new file system. This was to no avail and I fear that it may have made my issue worse.
My question, first and foremost, is how to proceed (this data is important but not important enough for professional services).
Secondly, would attempting the previous automatic method be of any use at all? That is: Format the drive using windows and using data recovery software to fish out the previous data?
