Can I copy the memory card files back on my re-fomated card?

Apav — Mon, 08 Aug 2016 04:15:32 GMT

I followed the instructions to reformat my memory card. I had the "invalid .jpeg" message on my camera screen. I first copied all camera files on the card to my desktop. I re-formated the card. The movie files now play. Can I copy the original camera files back to the memory card? Nothing has been renamed or otherwise changed.

If you only copied the images and not the folder I don't think it will work. The camera has a .ctg file that it needs but isn't downloaded. If you copied the entire folder it should work. By "work" I mean you will be able to view files on camera. Just copying the images is no problem.

I copied the entire folders (two of them), not the individual pictures. Thank you for the information!

OK. Good. Just copy the two folders back. Be sure to overwrite and not merge.

Just had a problem. I had some new photos on the camera, so I reformatted again. Then copied the folders from computer onto the card. Just looked at camera display, got "incompatible jpeg" again. Any suggestions?

Try formatting on PC and then copy the folders onto a blank card.

I have to ask, why? If the images are on the computer, just go forward from here and don't bother to try to get them back on the card. If that is your backup, you need to rethink things.

I keep copies on my laptop computer. For a while after taking photos, I like to share with others using my camera. Then I delete them from my camera.

Just what my neighbor does.

It almost sounds as if the files have been modified in some subtle way after they were copied to the computer.

Yeah, Canon warns that not all jpegs are viewable.

to kvbarkley - I'm always looking to expand my knowledge. Do you have background material/link on source of your info on jpeg viewability? Thanks.

I wish I could find a link, but one thing is for certain. Images shot on one camera cannot be displayed on another camera. It seems that camera firmware examines at least some the EXIF data [camera serial number?] associated with an image file.

Agree with that. OP is copying back to his camera.

No, I have no other information. Just the boilerplate in the manual.

One other thing that could be happening is that hidden files might be being copied along with the jpegs. For example, OSX creates files that have a '.' as the first character to store meta data. I know this has caused fits with some digital photo frames. The OP might want to look at the card with an option to show hidden files.

I need more information, please. I'm not very techy. What am I formatting on my PC and how do I do it?

Insert your SD card into the card reader on the PC. Select the SD card, right click and in the menu that appears select Format. Once it is formatted move the two camera folders to the SD card.

Am I doing a "quick format" or something else?

Re: Can I copy the memory card files back on my re-fomated card?

jrhoffman75 — Wed, 10 Aug 2016 02:08:35 GMT

Quick format will be fine.

I performed a quick format od hw card on my laptop, and copied the folders back to the card. Camera display still says "incompatible jpeg." Thank everyone for your assistance; I guess this is a peculiarity of the camera. I will mention this problem on a review on amazon.com. Otherwise, I love the camera.
