I just installed a replacement drive (Western Digital 250 gig) in a Phillips 7000 with the Zipper.
The hard drive is considerably louder than the 40 gig that was in their originally. In my PC's BIOS, I can change the performance settings of a hard drive either for optimum performance (but louder), more silence, etc.
Is this same technique possible with the Western Digital drive in order to make it quieter? If so, would I have to put it in a PC in order to change its settings then re-zipper the disk? Or will it perform at the same “loudness” in the Tivo regardless of what I do to it in a PC.
