Re: dd cloning slightly different disks
Thanks, Peter and all others. Indeed, in contrary to the expected, I went into my office this morning, swapped the HD against the SSD, and was able to boot both FreeBSD, Windows without a hitch or any other tweaking. The dd over USB 2.0 to the SSD from the WD hard disk took 21261 s (nearly 6 hours) I would possibly have had better results if I had both disks connected to a SATA controller and did the dd there, but so what, I'm there happily. Thanks for sharing. -- Christoph Will post bonnie results later. Peter Steele schrieb: Theoretically, doing a straight dd copy of one disk to another and then swapping in that disk should work.

Well, this could possibly work, but I wonder why you want to do it this way.I would be inclined to divide the disk as desired, do the MSW install in the first slice and then get a FeeBSD fixit and partition the other slice and then use dump/restore to move the FreeBSD stuff over.
