Get HDD Tune for free. That is enough for basic use. It allows you to scan sector by sector. Also do extended scan. It will also show smart result. You can also test the performance of the drive. The paid version is great for professional use and has more features.

The alternative would be crystaldiskinfo or using the built in tool in windows to check the health of your drive.

What a failing 8TB Seagate can look like in Victoria.

The 8 uncorrectable bad sectors has not increased since I took it out of the NAS, but this drive is not to be really trusted.

Those 8 LBAs correspond to 1 physical sector.

I notice that the reported capacity is 15628048066 sectors whereas the total capacity of the drive would be 15628053168 sectors. That's a difference of 5102 sectors.

The 127MB/s plateau would suggest that the transfer rate is being bottlenecked by an external enclosure. What kind of box are you using?

Yeah, I meant blocks, not sectors.

A version of this USB 3.0 dock:

The 8 bad blocks were initially reported by my NAS. Which is one of the reasons why it is no longer in the NAS...😉

If that dock is truncating the drive's capacity, then it may cause compatibility problems for those drives whose full capacity is accessible inside the desktop PC and which have been partitioned inside the desktop.

As said, it was reporting those issues in the NAS, before it was removed and used in the dock.
And it had been originally formatted in the NAS, and used nowhere else.

Noooo...

That is with the drive in the linked dock, connected to the PC.

Well in that case your dock is stealing those sectors at the end. This is what WD's Elements and My Books and Passports do. In WD's case, the bridge firmware reserves about 64000 sectors for its own use (SmartWare, WD Unlocker). The USB mass storage device that the OS sees is then shrunk by a corresponding amount. I have no idea what your dock is doing, though. Perhaps it's RAID or JBOD capable, in which case it could be storing the metadata in this area.

Edit:

Or it could be that your NAS has shrunk the drive by creating a HPA?
