Asking for trouble is correct.
After all, to get 24V and I don't think a typical 8" drive will
surpass 1A anyway, a LM317 plus a couple of passives and a small
transformer is  more than enough to do the job. If you get the LM317K,
then it'll even do up till 1.5A provided you give it an
appropriately-sized heatsink.
