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?
What are the results of a scrub on the filesystem? I’m not familiar with BTRFS, but use ZFS, and a scrub is where I would start in your shoes.
I did a scrub and this is what it showed when i ran
btrfs scrub status
:Duration: 0:17:54 Total to scrub: 63.82GiB Rate: 60.85MiB/s Error summary: read=528 csum=48 Corrected: 570 Uncorrectable: 6 Unverified: 0
Aaaah that’s a drive that should go in the dumpster asap.
Is the file still borked? Could just be the filesystem, but I’d look at the drive next.
Wonder if SMART uncorrectable errors count is high and the drive is failing.
