File reading failed: bad file descriptor

[highfive]

I've been looking everywhere for assistance on this one and I can't seem to find my specific situation.
I have a ton of family videos for two years including a baby birth, first everythings, really important stuff... I've emptied the SD card everything was saved on quite a bit ago and I skimmed them at that time and everything seemed to copy ok. Now that I'm backing everything up (yes, it's been too long) none of the video files will copy. I can start all of them, then after a few seconds, or a minute, I get the error "File reading failed bad file descriptor" over and over. Some of the videos I can open back up and jump ahead of the spot and I might get another few seconds... Some of the videos I can still hear audio, but the picture is frozen. I've tried turning off all running programs and I'm getting the same thing. I've also tried getting them on another program and I'm not having any luck.
I couldn't have lost all these videos... I'm sick about it... Is there anything I can do??
Thanks

Did you store these videos on an optical disk or magnetic disk ? They may lose data over time.

Copy the file to another file system before you open it in VLC.

I stored the videos on an SD card, I don't know much more about it. I cannot copy the files at all to another file or program

Flash based memory products such as SD cards, microSD cards, USB memory sticks are very unreliable. You need to make multiple copies before they go bad. I keep 5 copies for important files using USB memory sticks, microSD cards, and hard disk.

PS: I recommend to make 3 copies. If one goes bad, then get a new device and copy and maintain 3 copies always.

Yes, I have definitely learned from this mistake. But for now, I'm making any kind of attempt to recover what's lost.
