Was this card formatted on your PC instead of Camera? Always format your cards on Camera! Try using Lexar recovery software to reimage/format card.

If you have a 2 card camera load the pictures on both cards when you shoot. That way you won't lose any pictures. I went to all SanDisk after I had a problem with a Lexar. That was about 10 years ago.
I ( and you) must format the card in your camera every time you put it back in your camera. If you have more than one camera you must format it in the camera you are using the card in.
That should keep you safe. Remember any card could fail.

BebuLamar, Don't give up yet, Lexar are in my personal top ten (# 1 actually) of being problematic if not acting outright flaky at times. The programs on this first site have been around a long time and can work wonders when problems such as yours arise. They're free and are well written: TestDisk and PhotoRec 7.0:

SD Formatter does a great job of formatting any card, free; https://www.sdcard.org/downloads/formatter_4/

Recuva is one of the other greats for recovering any file from any folder or media:

The original sites where you can look the files and companies over, but you can also download these at Majorgeeks.com. Majorgeeks saves us from messing with captchas or having registering/creating accounts with email addresses, before being allowed to download important files, not the way many other sites do these days. There are many categories and types of utilities, and some very unique programs, some which are no longer in development, so it's worth checking out. A few programs are shareware or ad-supported but everything is clearly plainly marked; never agree to a license or click OK, so you don't inadvertently change a browser; they warn you about those too. A couple of great Texans run this site, and can't recommend it highly enough. We've used Majorgeeks for over 15 years to download just about any file one might need, without risk of picking up virus/malware/PUPs; have never downloaded a bad file from them.

Hope this helps and good luck with your Lexar; we recommend PNY, Sandisk, and Samsung cards are also good, sv.

I had a Lexar in my phone. It lost its marbles after about a year. I replaced it with a Sandisk.

" Don't let windows do anything to the card. Format in camera. "

In total agreement.

dsmeltz Loc: Philadelphia

I get and ignore that message regularly.

Keep the card, dump Windows seems to be the better plan.
SD Formatter is the site developed by the consortium of SD card manufacturers. Use it first, then format in the camera.

It's nice to hear that Lexar warrants their cards for 5 years. However, their warranty states "You must have proof of purchase and obtain warranty service authorization from Seller, including a Return Materials Authorization, or RMA, number within the applicable warranty period before returning defective products to Seller".

Do you keep your receipts? For $10-30 items? for 5 years? Are you willing to go to the trouble of getting a RMA for a small value item like that? What if you bought it from a place that went out of business? (You have to return it to the seller, not the manufacturer).

This is probably one of those warranties that look good but have little practical value. Unless you're really organized and have a great filing system.

On the other hand, as suggested above, a questionable card can be used to distribute files to someone else (thereby becoming their problem). So don't throw it away, give it away.

I had this problem. My newer SD cards weren't reading properly. I got a newer usb card reader and I now works.

Only format in the camera, NEVER in the computer. If that doesn't solve your issue, then replace the card. Any memory card can fail over time and use.

I have formatted many times on the computer and then put them into the camera without any problems. I have no idea
why people say format only in the camera. Unless they might be Apple users, Windows uses standard formatting. Does the
SD card mfg have any idea what the card is being used for? No of course not. The SD mfg uses a standard format also.

SD/microSD 2GB or lower FAT16
SDHC/microSDHC 4GB to 32GB FAT32
SDXC/microSDXC 64GB or higher exFAT
CompactFlash up to 128GB FAT32
CompactFlash 256GB exFAT

I ignore it as long as I don't have problems taking photos and getting my images off without problems.

The camera manufacturer could possibly put extra information on the chip that a computer may not use and be transparent to the computer, but the camera may use. Ya never know. It's usually safer to format in-camera.

DirtFarmer Loc: Escaped from the NYC area, back to MA

I suspect it's more likely that the camera could put information on the card during formatting.

While I also suspect it usually doesn't make any difference, it's easy enough to format in the camera so I do it that way.

If it's flaky and acting up, I'd discard it... First check to see if it's a problem with the camera. If the camera is the problem, no point replacing the card. If you discard the mem chip, destroy it so that data cannot be retrieved from it.
