--> Strange pulsing error

[skohns@kuhub.cc.ukans.edu (Steve)]

Hi-

I have an Apple //gs (rom 01, 3mb ram, 40mb Vulcan drive, two 5.25,
one 3.5) and I'm getting an usual pulsing light on my 5.25 drives.  
It's not the normal disk-access signal.  :)

It happens when the drives aren't in use and is a faint but regular
and noticable flash.  About 1-2 a second.  Both 5.25 drives flash the
same beat, but the 3.5 drive light doesn't show this pattern.

Any ideas on this? 
If so, please email me:

Thanks,
-Steve
