[quote=BebuLamar]To answer all. I have 2 cards and the other one never has such a problem so it's not the card reader. This one I never formatted it in the PC. I may want to try that. I didn't lose any images though.[/quo

You are wasting time on what seems to be a bad card... Throw it away and get a new one.

The card may have a problem with a sector of memory. I have seen this type problem in hard drives. If you run check disk on the card after you remove you pics and format the card in computer you may find the card has a bad sector in the memory. After all the memory card is actually sort of a hard drive only instead of being a physical drive it is a solid state device that has been formatted like a drive is formatted prior to use.

Thanks for the endorsement... I have several Lexar cards, and, never had a problem with any of them.

Yes those cards can fail in the computer and still be read in the camera. This is mostly due to the contacts in the camera and in the computer. Just like battery contacts the corrode somewhat or sometimes do not touch the contacts on the card dependent on the number of time the card contacts and the computer contacts and the camera contacts are used. Not used a lot they corrode. Used a lot they move out of place.

If a card act's up like that, get rid of it, don't even try to find out what's wrong with it. If there's nothing on the card you need to retrieve, just throw it away and get another one.


Why would you believe that the anomoly is with the card and not with Windows? I get this message often with storage devices other than SD cards.

I have a Lexar 32GB SD card and often when I put it in the card reader and connect to Windows 10 PC Windows asked me to let it check and repair the card. I formatted the card in the camera but then it still do that. Several timers already I wonder something is wrong with the card. Should I get rid of the card?


There is nothing wrong with either the card or with Windows. The operating system is only asking if you want to check the card, not telling you that there is a problem. If there is a problem, Windows will let you know after the card has been checked.

PS: To all those who toss their cards after getting this message, please don't. Send the cards to me. 😄😄😄😄😄

Leave the card in the camera. Use a USB cable to D/L to the computer. The biggest cause of cards going bad are because of mechanical failure. Leaving them in the camera or device reduces contacts loosening or breaking.


I agree with the comment "reduces contacts loosening or breaking". My problem of two years ago caused me much grief and money (for camera repair). I pulled the card out of the camera and downloaded the pictures successfully (good) but when putting the card back in, the contacts in the camera became bent (bad, and due to the card's contacts being damaged). I am now super careful and examine the card before putting back in the camera.

There are programs that can format the card to SD standards, use that, and then format in-camera.

Be careful with that advice. Windows actually asks you if you will allow it to fix the problem. The fix is a reformat, resulting in the loss of access to all your files on the card. If you can't see the pictures on the card in Windows Explorer, the operating system will assume that you want to format it. Don't do it if there is anything on that card that you want to keep.

Try using this:

If this doesn't work, toss it.


This is a sure fire way to format the card just like it came from the factory. Then if you format in camera and take a few pictures of your desk. Then see what happens. If it fails then pull string on warranty.

The camera (at least Canon and Nikon) does the equivalent of a quick format just clearing the file access table and may not excise all the evil demons.

Gold plated contacts do not corrode. They may wear some with excessive use.
Definitely - Body oils from fingers are really nasty on contact integrity!
