Last week I took a vacation to Georgia to go see my mother. I recorded some footage of the town where she lives. I came back home to California. When I arrived in California. When I arrived in California I wanted to review the footage that I recorded in Georgia. For some reason or another I could not get my camera connected to my laptop. to read the data from the sd card, i put the SD card from my gopro into my old INFUSE samsung phone which has an old android operating system. When i connected the sd card to the phone and booted the phone, that's when i got this error that said

Damaged SD Card

i panic because i had lost all that video from Atlanta Georgia.

i research online and found many suggestions but none worked. I checked with my buddy who is a computer genius and he told me to do these steps:

1. connect your damaged SD micro SD card into a USB card reader. When you connect it to your computer, windows might say to format, but DO NO FORMAT your sd card. at this point we only need to know the letter of the drive for the sd card. in my case it was F you DOS command prompt

3. Windows comes with a utility called Check Disk. We will use this utility to check for any errors and correct any errors if found on the SD Card. send this command:
chkdsk /X /F F:
/F = Fixes errors on the disk.
/X = Forces the volume to dismount first if necessary. All opened handles to the volume would then be invalid (implies /F)

4. when you send this command, you should get an output similar to this:
C:\Users\toshiba>chkdsk /X /F F:
The type of the file system is exFAT.
Volume Serial Number is B0CA-AFA1
Corruption was found while examining the boot region.
Windows is verifying files and folders...
File and folder verification is complete.
Windows has made corrections to the file system.
