Windows 10: SD card won't display video files

Windows 10 recognizes my camera's SD card, shows my jpeg and raw files, but video files don't appear. In the camera the video files show and play, but with the SD card in my desktop it shows no trace of those video files.

sd card problem with videos

It says the best driver is already installed. I really think it's an issue related to the sd card hardware or driver. The problem doesn't happen if the videos are on the hard drive.

 

Strange invisibility of camcorder jpeg files on SD memory card

Having just brought my camcorder back into use I find that while everything else still works fine, the still pictures saved / recorded to its SD Card are not (readily) displayed on my PC. They are not listed in File Explorer or alternatives to it and not found through Cortana and other search engines --- that is, with the exception of just one search engine. The only way I am able to tell they even exist on the card is with Wise Jet Search. which displays them quite normally.

Using Jet Search I have been able to Move them 'back' to the card, after which they do appear; a somewhat time consuming procedure. Strangely, or so it seems to me, while moving the files to the card one by one it does not generate a 'file already exists' notice, or start numbering them as copies / duplicates.

I have checked that 'hide files' is not ticked.

Any suggestions?

 

SD card/SD card reader no longer working

Hi. New to this so not sure of category.
I have a Lenovo G70. Windows 10, 64bit
My SD card reader has stopped working.
In Device Manager, the SD card is not listed.
I can't format the card as it is not listed.
I cannot locate the card at all as it is not listed anywhere.
I've tried chkdsk and get 'Cannot open volume for direct access'
I don't even have the icon displaying when micro SD card is inserted.
It did work previously but I had errors. Scanning and fixing did not help.
I place the SD card in my Android phone and it works fine.
Please help!
Thank you for any assistance.
