[color=ff0000]BEWARE !!![/color][/b][/i][/u]
I seriously fcuked up an A1200 in the past doing that:
the 2.5" IDE interface on an A1200 is unbuffered, meaning there is nothing between your IDE device(s) and all the tender and now irreplacable custom underbelly that makes your amiga what it is:
one current surge and you can seriously fry several custom chips: I destroyed Gayle, the CPU, and half the Chip-Ram ICs on the motherboard - cost me 50 quid to get repaired - and that was in the days when Wolverhampton had a shop that could send Amigas for repair.
I seriously recommend you visit
