I bought a SanDisk Extreme 64GB SD Card a few weeks ago which I accidentally removed from the card reader while it was formatting. I use it with my DSLR and format before every shoot.
This corrupted most of the card but I managed to fix it with formatting and
chkdsk <drive> /r, which now reports the card as being fine and free of errors.
Unfortunately, with some testing I have found that problems still persist.
For some weird reason when I go to playback any of my images, all of them are perfectly fine except the 3rd and 5th one. This suggests that there is still something on the card that formatting and chkdsk didn't remove and causes this malfunctioning.
This happened to another card of mine a while back, 2GB, whereby the only the 2nd image cannot load and causes similar crashes of programs like Windows Image Viewer and Adobe Lightroom.
Does anyone know what is causing this and (hopefully) how to fix it?
