I have a sd card in exfat format, I could not read it in ubuntu so I have searched for a solution and found this page:
SanDisk Extreme PRO SDXC 128GB Won't Mount
I followed the beginning of the instruction of the first answer:
sudo fdisk /dev/mmcblk0 and make a new partition table in MBR format with >o,n,p,1,Return,Return,t,7,w to make a new MBR drive with a partition of type 7 >(NTFS/exFAT) which spans the full medium.
after that I realized that was a bad idea because I had already a useful data on this sd card. So I did not continue and had NOT executed the next command:
mkexfatfs -n YourVolumeNameHere /dev/mmcblk0p1
I am not sure exactly what fdisk did to my sd card and how to recover my data now? Any help will be welcome.
Thank you!
