Hello, I just joined.
I have a 64 GB Sandisk SD Card, which I use in an Android phone. Earlier, I had formatted it into two different partitions and was using it with Link2SD to move apps to the SD Card. The smaller ext3/4 partition contained the moved apps and was about 6 GBs; the other partition was probably FAT32 and was used to store other files.
Some time back, I factory reset the phone, and installed another ROM. I continued using the same SD Card, and in File Manager, it would show up as two partitions - the larger one for my files and the other smaller unused one which I had earlier used to move apps.
Since the disk space had become low on the larger partition, I decided to format the second Link2SD app partition so that I could use it store files. In Windows, you can format one partition while the other stays intact (for eg. formatting D: drive doesn't affect C: drive). I thought it would be the same here, and so I used the default file manager to format the second smaller partition. It started the process, and then I suddenly thought that it might mess up the larger partition, so I closed the app. When I opened file manager again, I found that it had formatted the whole SD Card (both partitions), and it was showing up now as exFAT. I immediately took out the card from the phone and inserted into the computer.
I tried using PhotoRec to recover the files, but it finds 0 files. I have tried both options, the first as whole disk and the second as exFAT. I have also tried the ext2/3/4 as well as the FAT/NTFS/HFS+ file systems. In all cases, it comes up with the nothing. I have tried a few other software as well, like Recuva, Easeus Data Recovery, and some others, but none of them finds anything.
HxD shows most of the data as zeroes.
In summary: I had a 64 GB SD Card split into two partitions - a larger probably FAT32 that contained my files, and the other smaller ext3/4 that contained moved apps. Accidentally formatting the card has made it into a single exFAT partition. I want to recover data from the first larger partition.
I have created an image.dd file and now am working from that, but I also have the SD Card and can work from that if required.
