Bad starting sector (CHS and LBA don't match)
Posted: 09 Mar 2016, 03:51
I've recently been using a USB to Micro SD adapter, and that has been causing me disconnect issues recently. I used the SD card to Micro SD adapter, and now my MicroSD fails to work, and returns an error message "The disk you inserted was not readable by this computer."
Upon running TestDisk , I was able to find the error of a bad starting sector.
The log is above.
What further steps should I take to recover the SD card's data* and make it usable again?
*Note: I have run PhotoRec and gotten back 23 gigs of my 64 gigs of data. Can I recover more?
TL;DR CHS and LBA don't match, need to recover data and disk.
Thanks
