What's wrong with the disk?

Question

Hard disks

Good afternoon,
In the error log I see a lot from smartctl

Mar 28 20:54:16 HTPC smartd[777]: Device: /dev/sdc [SAT], 43 Currently unreadable (pending) sectors
Mar 28 20:54:16 HTPC smartd[777]: Device: /dev/sdc [ SAT], 43 Offline uncorrectable sectors

smartctl -a /dev/sdc

Is this a coincidence interesting or not that lifetime 666 day ?
Actually, I don’t see critical parameters for smart brands, except for the case of disk overheating:

194 Temperature_Celsius 0x0022 049 056

What can you say about the state? And what is this Error 126 ?

Answer 1

The disc fell off. id187=199, one reallocate, non-zero id197 and id198, id195 != id1 also id199
I don't see the disk model, but even 52 degrees is not very critical.
As for "Error 126" - it's just the serial number of the error, you have the entry "ATA Error count: 126" a little higher. It just displays only the latest ones.
Everything is very bad.

Answer 2

What. Behind. Disk?
smartctl writes errors, but they are not always adequate. Although in the vast majority it is worth paying attention to them. If, along with SMART errors, the disk shows instability, then we are waiting for orders to live long. If not, then we carefully read the data, go to the vendor and look at the implementation features. In general, no criterion has yet reached its bottom. As for errors, they can be for various reasons (power supply, firmware features, controller stupidity), try to burn the disk completely with zeros (random), and then format it.
