I have some locally stored media i was copying between drives and one mkv file gave this error error reading 'video1.mkv': Input/output error and only copied 176/256 MiB; the copied file plays the video only up to a certain point before abruptly closing; I can play the original file fine albeit there is a noticeable hitch at that point but the video plays normally till the end I have tried zipping the file but it fails to zip it I tried copying it using ffmpeg but it also gave the same error I can copy the file in the same directory but trying to copy the copy also gives the same error I tried copying to a variety of different storage drives and it still gave me this error any ideas?

    Is the copied file going to a usb? Is the usb fake? Otherwise I’m pretty sure your source is bad. Probably the disk sector if you’re sure the file was at some point complete.

    Something like btrfs probably does block cloning or similar so a copy to the same disk probably just points at the same disk blocks as the original.

    ffmpeg -v error -i file.avi -f null - 2>error.log

    Check the source probably
