Pure Data Write To Hard Drive

I installed in december 2011 my sound data for bfd-eco, an acoustic drum vst that really rocks. By that time i had my akai mpc 1000 connected to my computer to do some sampling. While i didn't do any sampling while the installation progressed i did hear that the external hard drive that i was installing onto sent out disturbing binary pulses that my mpc picked up. I quickly started the sampler, and recorded as much as i could of the noises. This is the result.
