Purchased an st33000651as 3tb drive off ebay.
obviously, a risk hopefully it's a reliable drive-- they ALL have their share of 1 egg on newegg for DOAs, or dead in months.
After a bit of finagling to get it to see 2.7tb and not .7tb,
I did a full format (took 6 hours!) on thursday,
moved everything onto it (1.2tb of data),
was away for the weekend
so I then did a disk check last night (took 8+ hours!)
From the below, just to be SURE, all's well? No noises are coming from it either btw.
I don't know how bad sectors work.
Is it possible the drive had 20,000 bad sectors and was in a bad way,
but the full format sequestered those bad sectors, and that's why it reads 0?
Or is it definitely quite healthy. Just being safe-- while there's still an option to return it to the ebay seller if there's any reason.

The error checker built in to Windows is not the correct method to test the health of the drive as it only tests the data on the drive, not the drive itself. You need to test it with the manufacturer's diagnostic software, which for Seagate drives is called SeaTools: http://www.seagate.com/gb/en/support/downloads/seatools...
If the drive contains the operating system, you'll need to use SeaTools for DOS since it can't be tested properly while Windows is running.
