Hi,
I fixed those cables myself, u dont need to buy that expensive IDE Kit!
check this site on how to make the power cord for the HD
http://www.basscadets.co.uk/emu/faq.htm
and as for the IDE flatcable, get it from a second hand computer store.
look for an older ATA33 cable that has all the holes. they are usually quite cheap.
i now have a 17 gb IDE internal drive and it all works allright.
Best regards
Juan
