From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

A SMART Test showed 6 bad sectors but overall disk assessment was ok(I dont think there is any connection between the file and the HDD), yes that file has not been fixed, the disk in question used to be my main bootdrive a few days ago, I shrunk the partition and created a new EXt4 and i am slowly copying files that are worth keeping, i removed the ODD from my laptop and installed a caddy, intend to use it as a second drive(The file in question has no sentimental value)
Okay cool. I would be wary of that drive just in case, and I would definitely schedule weekly SMART short tests and monthly BTRFS scrubs on it if you go with BTRFS in the future. EXT4/XFS/etc do not have a concept of data checksums, which means they can't scrub and check for bitrot - this might be problematic if you find that your disk starts causing bitrot because you won't know where it's happening.
I follow Backblaze's rules on detecting impending drive failure:
If any of these SMART metrics are higher than 0 I'd expect failure soon and take precautions.
Thank you Id 197 and 198 reported 5 & 6 respectively(bad sectors decreased from 6 to 5), Is it possible to copy a file non sequentially; say back to front so i can just join those 2 parts together?
Try this answer. I guarantee there is a way to read the file front to back while skipping errors, but I run so much data redundancy that I don't have any experience with it.
Thank you
