Sd card movie storage problem

December 27, 2016 at 09:07:49
Specs: windows10
I have been storing films in various formats (AVI, mpg mp4 mkv and dvd's) on various

SD cards with 256 gb.
I tried to to play one the other day and it says can not render file and various other

error messages. i use mpc-hc player, vlc and got several other ones. i tried other

computers and other files, i got i laptop which allows the card to be plugged in direct

and i got usb adapters. the cards appear to corrupt the files, but as there are so

many different cards and files i find that hard to believe. the cards are fat formatted.
any ideas please how to fix the files or what is going on? am i missing the obvious

Storing files on SD cards is a very bad idea. They do go bad as you are now finding out. Yes the cards are most likely why your files are becoming corrupt. You should opt for a more stable storage medium such as a DVD or online storage.

Have you previously played the same type of files off that same card?

What version of FAT do you have on it?

How did you format the 256GB card with FAT?

Your laptop may not be able to read an SD card that capacity.

They are various sd cards, they are not all 256 some are 32 some 64 etc, they are various makes like Kingston scandisk etc. I also use several different computers with different operating systems like windows 10, 7 and the old xp some with an usb stick and some plug in direct, yes I have after moving the files played some and they are fine. Now they are not. I have also ejected them via the taskbar “safely remove hardware”. My laptop is only 1 year old from new and can take sd cards this size. So different cards different computer different plug in system yet movie files are not playing but they are there alright, pictures and text files display/open ok. The cards are mainly used to archive stuff and we are talking on several cards Terabytes of stuff and therefore too many disks would be needed. Because of different cards, makes and system of use I find it hard to believe they are all duff and that would be strange odds.

I agree that it is unlikely all your cards a flash drives have failed. More likely the file systems have been corrupted.

I have also ejected them via the taskbar “safely remove hardware”.

Using the “safely remove hardware” function is critical to protecting the file system on any disk. Especially larger capacities. If a disk is removed prematurely it will probably corrupt the file system.

You can check to see if that is your problem by viewing the cards (disks), in Windows disk management. If the file system is shown as "RAW", then the file system has been corrupted.

The data is usually still intact but Windows doesn't know how to find it. There are a couple of utilities that can repair corrupt file systems. Testdisk is one and Easeus Partition Recovery is the other. Get both from the links below. Testdisk is more comprehensive but a little harder to use.

Post what you find listed in Disk Manager for your cards.

If the file system is showing FAT32 then Easeus probably isn't going to do anything for you.

If the cards show in Disk Management then try Right clicking on the drive and choose Open or Explore.

FAT32 has a 4GB file limit size. Also, path depth limitations come into play.
