We have a Western Digital 4TB Spyglass with donor heads and PCB that was cloning at 100MB/sec when we powered it off on Friday (with an average speed of 71MB/sec). This morning, when we powered it on to pickup where it left off, we are getting 4.5MB/second (with an average speed of 3.8MB/second). After grabbing the screenshot, we jumped around a bit and were able to hit 70MB/second again, suggesting that there are areas of slowdown. So, we aren't likely to have the drive cloned in 11 1/2 hours, as implied on Friday, but it should be faster than the close to 9 days predicted by the slower average speed of 3.8MB/second.

What I mostly regret is to power off a drive and never get it working again...
Happened yesterday on a Samsung that was imaging at about 5Mb/s after a head swap and to try to make is faster, it died....
Now, each new head kit I swap, they got killed as well...

Yup! Been there, done that.
