3.5" Drive for Apple ???

Greetings, Last week, along with a boxload of other stuff, I picked up an external 3.5" floppy drive that apears to be intended for Apple machines. It's a DS800 from DataSpace Corporation. It physically plugs into my Apple //c, but I can't get the machine to recognize it. The drive makes a noise when I power up the computer, but that's all. Attempts to access S6, D2 or any other slot and drive combination doesn't get anywhere. It DOES respond to my Mac 512K, though. I plugged it into that machine and shoved a Mac-formatted disk in it, and an icon and open window popped up. I don't think the drive can be intended for the Mac, though, because it's got a MECHANICAL eject mechanism. In fact I was able to eject that Mac disk (write protected, thankfully ;) ) and the Mac didn't notice. Is there something I need to do to get my //c to recognize the drive? Or is it intended for use on a //gs? Or did this company make a line of dangerous Mac peripherals in an attempt to give the platform a bad name for an overabundance of disk corruptions? ;) Doug Spence ds_spenc(a)alcor.concordia.ca
