expected time for 8 TB hard drive

[Frantz]

Greetings! I was happy to starting running Spinrite 6.1 today on a Linux machine. The installation onto a USB drive was smooth. I was fortunate that I could locate my registration email of Spinrite 6.0 from 2005.

My question is around the expected time to complete. For an 8 TB drive with spinning disks (not sure of the specific make of drive), it showed Level 3 as 25 hours and Level 2 as 12 hours. I'm curious if these times look roughly normal.

I completed 42% on Level 2 and plan on resuming overnight assuming I can figure out how to resume. Running Level 3 would take multiple nights and would be a bit of a hassle.

Great job on this Steve!

Those numbers sound right to me. Keep in mind that they're a little optimistic, though. Drives slow down as they get closer to the center.

To resume a scan: go through the normal steps of starting a scan, but hit TAB on the last screen before the scan starts. That will let you enter the starting point.

Thanks for the information and quick reply Colby!

My 8TB Seagate ended up taking 14.5 hours. See the logs I posted of my level 2 scan here:

That looks about right for a “spinner”. I've been quoting half a terabyte per hour, so two hours per terabyte. SATA III SSD's, of course, can perform much faster. But that looks good for a spinner.
