Hello,

Here is almost full output of dmsg.
And here is the error itself.

[  802.432473] ata3: exception Emask 0x10 SAct 0x0 SErr 0x4040000 action 0xe frozen

Initially this error start showing up a month ago. It wasn’t making any problems until one day I couldn’t start Arch at all. The error was looping for infinity. After few tries of restarting I decided that it might be a HDD failure so I took a spare HDD and went to install Arch again. But when i boot from USB the same error pop up. I gave up Arch and installed Mint. Strangely enough I didn’t got any errors. But Mint wasn’t working for me, so I gave up and install Arch. And the error returned. I don’t know when the next infinite loop will appear.

I found this post, might be similar. But if it is a SATA cable why I didn’t have any problems with Linux Mint.

This is the output of lsblk

This is the output of fdisk -l

And that’s the output of sudo smartctl -a /dev/sda.

So what I can do about (is there anything at all) this error (and continue using Arch)?

Thank you.
