Thank you very much, I will dig into all this. I remember checking for SMART and having no response from it (despite the computer getting the right info from the device's manufacturer), is it possible that it doesn't have it afterall?

SMART is usually not implemented in external USB enclosures. Check Seagate's own tools to see if that particular one is supported. Bad Block reallocation is not handled by SMART, only reported by it to the user/OS.

An external hard drive is usually just a regular hdd with a plastic chasis, and a tiny USB to SATA adapter, so many do support SMART. Whether or not its accessible over USB is a whole different matter. Some USB to SATA circuits allow SMART data to pass and some don't.

It indeed is a regular HDD in a plastic case, but I don't know whether or not the SATA/USB adapter handles the SMART in that case. Also, I tried using Seagate tools, but they didn't do anything (no result... The tool itself looks reaaally outdated too, but heh)

@Rinyuaru-Kun If the drive isn't under warranty, or you don't care about the warranty. Then you can take it out, and connect it a PC with SATA cable to do the diagnostic work, it will be faster than USB 2 for sure. USB 3 would be the same speed.
