Re: Curiously...
The only issue I have ever had with Acronis was a a dodgy USB 3 port and the HP Recovery boot partition on my mothers HP laptop.
The USB 3 port kept disconnecting the USB to Sata adapter, went to the USB 2 and it was stable but slower. I was lazy with the HP Recovery Partition by deleting it (Pretty sure GParted wouldn't have had an issue with it).
However read errors are never a good thing, I've had an external powered caddy with a back fan and found it was pretty bad for imaging where it would disappear from the USB bus (Which was annoying as I wanted to replace a frankenstein external USB drive I nicked the case and board from), never had read errors before with Acronis..
