dd cloning a Win10 HDD to SSD

[Bill Freeman]

Probably only if you're getting read errors on the old device.  But I'm not
a particular expert.

Re: using dd at all, the target drive must be at least as big as the source
partition.  (I'm assuming that everything uses LBA (logical block
addressing) these days.  In the bad old days we had to worry about the
number of heads and sectors: dd would make the copy, but various OSes might
not be able to find things.)
