IIgs ticking noise from speaker when using GS/OS

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?

troubleshooting suggestions

I can't answer your question definitively but the start of basic electronics trouble shooting would imply there is interference coming from the drive, however elimination is still needed.

 

1. Does it occur with any other software being booted from the drive?

2. Do you have access to any other drive to try on your GS or any other GS to try your drive on?

3. May sound strange but try moving the drive as far as the cable will allow from your GS and see if there is a change in pitch or volume of the noise.

 

Unless someone here recognises the specific problem start with the above.

GS/OS Control Panel Sound Settings

Have you checked the control panel settings for noises that can be optionally set for various disk access actions?

The noise completely absent

The noise is completely absent when performing same actions using emulated disk via CFFA3000 or a real 5.25" drive, OR when not using GS/OS.  Nothing changes with moving the drive physically further away from the computer. Unfortunately I do not have another GS at the moment to check. Looking for a ROM 3 right now...

 

Unless somebody can point me to more troubleshooting, I think I'm just going to disconnect it and keep using the CFFA. Not the end of the world, but would like to understand the issue...

To confirm, it is a "dumb" 3

To confirm, it is a "dumb" 3.5" drive and not a "smart" Unidisk 3.5, correct? I recall when I tested my Unidisk on my gs, the drive activity light would frequently flash at steady intervals for no apparent reason when I booted the gsos setup disk.

 

 

I don't recall if it did it with the disk in or out, though. At the time I was just using the gs to confirm the function of the drive and eject mechanism. So I was constantly inserting and ejecting. But I definitely recall the access light flickering in scenarios where the "dumb" drive did not.

 

 

I haven't spent a lot of time in gsos with my "dumb" 3.5. But definitely do not recall any kind of noise though.

Yes, it's Apple 3.5" Drive, model A9M0106, and it doesn't matter if disk is in or out. Also, the LED stays off.
