Forgive me if this is a common question, I've googled a bit and all I could find is threads about clicking noise from drives.
I have a ROM 1 GS, with new power supply and CFFA3000 card. The computer is perfectly quiet when using drive emulation with CFFA. However, when I connect my recently acquired Apple 3.5" drive and boot GS/OS, there is a ticking noise about twice a second through the speaker. The sound dissapears when selecting a menu, or holding the mouse button in general. Any ideas?
