I had a 1TB Samsung 9xx Pro fail on me in a Windows 10 PC. One day the PC wouldn't boot, said there wasn't a hard drive there. I put the drive in an external USB 3 case and with Linux, I could dd from the drive, but it was running really hot and had an unusual access pattern: it would run for about 5 seconds and then pause for 30 seconds. I think the pauses are what screwed up the Windows boot because it wasn't waiting long enough for the drive to respond. I eventually did get the drive copied w/o data loss, though it exceeded even Linux's timeouts a few times during the copy and I had to restart dd with an offset to get the whole thing copied.
