Hi Shane
I ran HDD regenerator & seatools on a different PC, which doesn't have SB scanner installed. Although HDD regenerator reported issues with 7 sectors & recommended backing up the HDD, it didn't actually report any bad sectors in the section below the progress graph but obviously it found something it didn't like, hence the suggestion.
I've 6 HDD's & 1 SSD on the PC that reported the problem; one of the HDD I only replaced after the issue with the problem drive & everything is normal even using the same SATA port & data cable, so it seems the HDD that has the problem is actually faulty but seatools says it's OK!
I've RMA'd the HDD & returned it to Seagate so can no longer test it.

Hi All
This post is more information than asking a question.
I run a Win 10 PC backup PC with 13 HDD's; randomly, DP & Scanner would report a missing disk. A Windows reboot usually fixed the problem but recently the problem has been occurring more frequently. I ran Seagate diagnostics & the HDD passed all tests. I swapped out data & power cables & tried connecting the HDD to another SATA port; problem still there.
Finally, I upgraded to a larger PSU, 700W to 850W, & the problem has not reappeared since.
The big difference in the 700W versus the 850W psu was the +12V line; 48A max in the 700W psu & 70.8A max in the 850W psu.

ps
I don't like the term 'duplication' which suggests 2 copies of files/folders are created. I store 3 copies therefore 'replication' is a more appropriate term for more than 2 copies of files/folders. Call me pedantic!
