I've got a problem with my HDD. My Arch usually boots like thunderbolt, but since 3-4 days it freezes for a while before login screen. So I checked dmesg and this is what I found:

It would be great if someone could help me a little to prevent some major incident and point out what's happening. Thanks in advance!

If my math is correct you have more Current Pending Sectors and Offline Uncorrectable sectors than user accessible sectors on the drive (over 4x), something seems to have gotten seriously screwed there. I have never seen anything like that and logic would say that it shouldn't be possible.
Also this doesn't inspire confidence:

I'm guessing that you're looking at that figure of 4294967295. That happens to be 2^32-1, or the unsigned value of -1, so it's more likely to just mean "undefined". The other events hint towards a failing disk, although if it was me, I'd do a google search on the messages before paying out for a replacement.

Thanks both of you for feedback. Problem still remains and it's getting worse. When shutting down Arch it came up with errors like:
EXT4-fs ext4_da_writepage: jbd2_start: 8192 pages, ino 1704770; err -30
and hanged up . Then it didn't even want to boot up, console output was all screwed up. Right now it is working again, but I'm afraid of shutting it down :E

@pok0j
You best bet at getting the most uncorrupted data out of that disk, is to stop using it until you get a new disk that is at least twice as big as that one. The reason is that when you get a new disk, you want to try to do a full disk image in one go and get as much data out as possible before more data corruption occurs or the disk stops working at all.
The twice as large requirement is because you can then take your time to extract the files you want from the image and have enough free space to store them. After that make a backup strategy if you don't have one yet.
@drhill1
Has far as I know, both Current_Pending_Sector and Offline_Uncorrectable attributes start out at zero and 1) increase when there is a problem with a sector, 2) decrease when the problem is solved either by overwriting the affected sectors or when the sectors get reallocated thus decreasing the count, which should return to zero when there are no more sectors with problems. This implies that the count should never exceed the total number of user addressable sectors. Like I said, I have never seen any disk where those attributes didn't make sense, if those attributes weren't defined they wouldn't be reported I suppose.
