PM corrupts card

[jolson49]

running PM 4.5.4 on Mac intel 10.6.8. I'm a pro shooter havinh used Canon gear and Photo Mechanic for many years. Great product.
However, when I now expose cards (Lexar or Sandisk) in my new Canon 5D mk lll and use PM to select an edit to tone, the camera will lock up, giving me an Error 70 and will not recognize the card. It can not be reformatted in the camera. I have to use the format feature on Lexar's Image Recovery to reformat in the computer before the camera will again accept the card. All I do in PM is to apple a check mark to my desired images, select them and copy them to my computer to be toned. Two Canon reps told me they've never heard of this so, as usual, I'm the only one in the world with the problem. Wait, does that sound a little frustrated? I have the same issue on my home computer running OS 10.9.

First of all, never ever edit images directly on the memory card. There is a good reason, PM has this disabled by default!

That said, what you are seeing is quite a strange and interesting phenomenon
Are you editing your images while they are on the card still in the camera (I guess this would be the worst scenario), or when the card is in a card reader (slightly less bad)?

Never edit on your card.  Always Ingest or browse and then copy, but never make changes on your card.

PM 5 disables editing on camera cards by default.  PM 4.5.x did not have that precaution and will allow you to edit on your card, but do not do so.

I too wanted to chime in. I did find a few other people that have that problem when doing a Google search. (It's not just you after all!)  It is happening because the 5D MkIII is reading metadata off the card, and it is very finicky about the metadata format. PM is not corrupting the card, but it is changing the metadata on the images when you choose to apply tag there, which the 5DIII does not like when it tries to read.  There is nothing PM can really do to prevent this from happening except to try to stop you from editing on the card, as the 5DIII just doesn't like it when the metadata changes.  As Kirk and Hayo said, it is so much safer for your images to ingest them all to your computer first.   But, most importantly.. you are not alone!
