Hello.

 

I just bought a floppy drive and it may seem defective. I DID load at least ONE disk (System 7.1 install disk 1) but then it went crazy. Now all it does is make one beep every few seconds. What happened?

PowerMac, Mac OS X (10.5.8)

    Perhaps you need some kind of driver? Without a driver, OS 10.5 may well be wondering what the heck is a floppy drive?

    "I DID load at least ONE disk (System 7.1 install disk 1) but then it went crazy."

     

    The OS 7.1 install disk set is likely on 800K-formatted floppy disks.  The easiest way to differentiate between a Double-Density (720K) and High-Density (1.44 MB) disk is the extra hole at the back corner on the 1.44 MB disk.  A Double-Density disk only has the single hole with the sliding lock tab.  Modern USB floppy disk drives support the 720K and 1.44 MB disks used in PCs, but don't support Apple's 800K-formatted disks.  Apple's FDDs had a variable-speed motor, which enabled them to accommodate 800K of data on a 720K disk.  This is what caused the drive to become unstable.

     

    "Please also note that I had a floppy working at one point."

     

    If it was an Apple-formatted disk, I assume that it was a 1.44 MB type.
