Linux

I've been on Linux for close to a year but I'm still kinda a newbie and the past 40 something hours have been really testing me.

I had my 4tb backup HDD break on me in a strange way, it still mounts and at first glance seems to still be working, But KDE throws an error saying the drive won't mount (even tho it is?) and I'm unable to copy files from it using Gui or Term commands it just freezes up without throwing an error message, It also freezes after using Ls more than once or twice on it.

Now last night I used clonezilla to copy the entire drive to a portable HDD of the same size, now that drive is giving me the same issue. So I'm assuming it's a software issue and not the drive itself? at least for the 2nd drive.

I already tried fsck to no avail and I'm abit stumped on where to go from there. Any help would be great!

Edit: Should also add the drives EXT4

Update: At the directions of a Gentoo nerd I know. I'm currently in a live boot of Ubuntu copying files to another drive and they seem to be working so far.

Part of the issue might with my few month old install of Endeavour, But I'm still gonna replace the drive. I already paid for a new on.

Another Update: I was able to recover the majority of my files to other drives by running an Ubuntu live USB and copying them over on that, So seems something on my main install was preventing me from copying files? Either way the drive itself is still done for and I got two others on the way to replace it, I've also reinstalled my distro as I was having some bugs with it anyway.
