My computer recognizes the card as a 32GB card, and I can view the 50 new images. But running testdisk, it appears as a ~250GB disk and gives the warning "Bad starting sector (CHS and LBA don't match)". Is there a way to fix this in an attempt to recover more from the card?
Thanks for any possible help. Here is the log.
