Computer idle sound features harddrive seek noises even if no harddrive is installed

[iovoid 0]

I once was in situation where I was close enough to getting away with using only Microcontroller, if not for their inability to interface with Adapter. EEPROM-only computer making harddrive noises is minor immersion break. Would be nice if they produced different idle sound if there's no harddrive or even entirely relied upon disk activity sounds that happen during actual disk IO.
