Corrupted images with M-P ?


Recommended Posts

Like all removable media, SD cards are yet another way to spread viruses. Locking them before inserting into a computer is a sensible precaution; not that YOUR computer has a virus, but you may load the images onto someone else's computer and infect the card. Being in the habit of always locking means this won't happen.

Where I worked they had kiosks at the entrances where you could disinfect usb disks and memory cards.

Ridicule is in the eye of the beholder.

 

Protecting your card against being written on is standard practice if you use your card on computers not under your control. Given the amount of stuff most computers write on your card, it's good practice even with your own computers.

That is good practice to avoid a card being infected on other computers.

However, a virus or any "amount of stuff" written in the card will be cleared as soon as the card is formatted in the camera.

 

Therefore:

- Import images to your disk

- Format the card in camera

Not a computer expert,  but perhaps what JAAP means is the file is removed from the card, stored on the computer,  then written back to the card.  This is asking for trouble if you ask me.

 

128 GB are not suitable for M9.   I believe 32 is the max.

 

I hope you formatted the card in camera before you used it!   Standard procedure.

So where does SD Formatter come into play with this discussion?

You're the first one to mention it here, I believe.

 

I see a partially blacked picture in the illustration provided by the TO. Missing parts of pictures might indeed point to data lost on the card. In such a case I would indeed format the card using the "slow and thorough" (it's not called that, but I can't recall right now)  option of the SD formatter, hoping that this would detect and flag defective blocks. I have been wrong here on SD cards more than once, though.

 

The "quick" formatting option only stores a new FAT and directories on the card and leaves the rest alone.
