You should NOT use +6V power supply, especially one for answering machines, if you connect it to the cut +5V USB wire. This is because: a) The USB standard calls for +5V power b) These power supplies are just transformers, with no regulator. What you need is a +5V regulated power source, which you can easily make yourself from one of those 7-10V power supplies and the 7805 regulator (with a heat sink). Just calculate the voltage drop on the regulator to not exceed the regulator's max. dissipated power. > powering thru the IDE directly might be heck of a job for me, coz' i'd have > to saw apart the IDE connector or rip off the soldered leg. Your computer *already* has regulated and quite clean +5V and +12V power. You can connect to there if convenient. Two black wires in the middle of the connector are ground, two on sides are +5 and +12V. If you do so, be aware that you will be bypassing normal USB power safeguards that shut off the power in case of overload. If the soldering iron is not your best friend then maybe you should return the device and buy something else, better designed :-) This one seems awfully half-baked. If you intend to connect the external power supply to the "DC In" connector on the drive enclosure then it might work, but I do not know what DC the device expects, so you'd better check the manual. The +6V DC would be a little bit low in my book because you'd have next to nothing to fall on the regulator (0.7V min.), and without that spare voltage the regulator won't be effective - assuming that the enclosure has a regulator inside.
