I managed to test out the IIsi's hard drive by puting it into my LC and then booting via boot floppy.

I have never heard a hard drive frantically click so loud in my life. it currently sits on my desk, dissembled for the fun of it.

So far this IIsi has been nothing but a disappointment. Riser card exploded, hard drive is faulty, memory useless for the 575, and the power supply probably doesn't regulate the voltage very well.

And I already have an auto-inject SuperDrive! Well, at least the battery isn't dead.
