I was very surprised that things worked well when moving one IDE drive
to another system. It booted up and detected a number of differences in
the motherboard chip sets and removed and installed the correct drivers
for the new system. Went much smoother than I hoped.
The biggest problem you may run into is if you use a different
architecture for the CPU. There could be some issues there where
loading the correct kernel for the new system prior to moving the drive
maybe prudent.
As to SATA I don't have as much experience but the thing to look for is
the specific chip set used. I have one motherboard that has two SATA
controllers on it. The Silicon chip set was recognized and was usable
during the install process. The other which I think was an Intel chip
set initially did not see any drives I connected to it. I think since
then I have found an option in bios that would resolve this problem.
The option made it use a shorter time to detect the drive and this was
timing out. However I have not made time to go back and test this.
So if you have the same SATA chip set between systems I don't see any
reason this would not work. If they are different then you need to do
some additional checking.
Use lspci to get the information on the chip set used.
