I'm now playing with old SATA 1 Seagate 1TB Barracuda. I know that there is one very old and
uncorrectable bad sector as can be seen from smartctl -a output:
40 51 01 62 14 56 40 Error: UNC at LBA = 0x00561462 = 5641314
However recently when I start playing with Fedora 40 and LibVirt there was very new error in dmesg:

When I googled for Unaligned write command I found quite weird reports:
Some suggest that drive is dying while other recommends to disable ALPM (I should try it, because this HDD is very old so it definitely knows nothing about ALPM)
