I'm having some issues with one of my memory cards. I bought my memory card from Walmart, this one to be exact, and usually, cards work right out of the initial opening so I never really format them before use. (I should probably start doing so after this technical problem.)
But my issue is that the card is reading "memory card error" right now. My brother had used it in a camcorder and it started to record some video clips to the card, then halfway through his usage, it started to read the "error" text on the camera whenever he tried to record something else. So I tried to transfer these files that he had recorded to my laptop, but I wasn't able to, and I was not able to delete these files from the card either.
I'm on a Mac, and I've tried to manually delete these files from the card via my usb card reader (but they keep coming back), and I've also tried to repair the disk through the disk utilities program that's on here as well. I am not able to format the card in the camera that it was being used in, or in any other camera. (I've tried the camcorder, and 2 different Canon point-and-shoots.)
Is there any way I can fix this card so I am able to use it again? I threw away all the packaging (because I assumed it would work right out of the package, like I always think) and I'm not sure where the receipt is. (If I were to find the receipt, I think I might be able to send it off to SanDisk since I just bought this card a few weeks ago). Right now, I'm just looking for any options that I can try to do here at home.
If anyone can help, thank you so much in advance!
