Yes, you can get that effect if its retrying on bad sectors and succeeding eventually.
That doesnt appear to be your problem tho since the Seagate diags dont see any problem.

Yes.

Check if DMA is being used for that drive. Win will turn DMA off when it
sees a number of errors in comms to the drive, for the safety of your data.
Thats usually due to a bad cable and is the first thing to try if DMA is off.
You will need to manually turn DMA on again if that is the problem.

If DMA is on, see what the speed of the cpu is being reported as.
You can see the bios have a massive brain fart and run the cpu at
way below the speed its supposed to be running it at and get that
very noticeable slowdown. If that the problem, try resetting the
cmos and if that doesnt fix it, try replacing the cmos battery.
You can also see the system deliberately slowed down because
its overheating. Check the cpu temp with something like speedfan
and if thats way too high, check for fur in the cpu fan and that its
actually rotating at the correct speed etc.
