exFAT SD Card on Mac Corrupted - I've tried a lot of things
Posted: 19 Oct 2017, 06:49
One day the SD card stopped working in my Mac and tells me to "initialize" it, so I open disk utility and try first aid and I am met with this:
Googled and tried to self-solve and found this: https://craigsmith.id.au/2014/07/06/rep ... partition/
I tried It but never got "Main boot region needs to be updated. Yes/No?" and this was the result:
I then remembered TestDisk - I have used it before for the Boot Camp partition, and I read the guide here: https://www.cgsecurity.org/testdisk.pdf
I tried the instructions in section 7.4 and copied the backup to the main; still no luck--same as above.
I tried to search and write a partition; maybe I'm not doing it right, but no luck.
I tried chkdsk on Windows, but the filesystem in RAW.
I haven't reformatted it, but I have used EaseUS to recover much, if not all, of the data, but it didn't keep my folder structure and I'm sure not everything is there/uncorrupted.
Any ideas? Thanks in advance. I tried to do my own research before asking, but now I'm stumped.
