It sound like to me that you have either a problem with the controller and/or the drive itself. Is you floppy a 5.25" 1.2MB drive or a 3.5" drive (either 720kb or 1.44mb)? If is not, you need not worry about pin-34. Pin-34 on the 360kb drive are always grounded. Things to try. First, make sure that the cables are on correctly, colored edge to pin-1. Next, format a blank disk on another computer and place it in yours. Now try to copy a file to this disk. If it fails, most likely it is your drive. If not, see if you can read the file on the other computer. If the diskette every shows up as being bad ... the drive has a faulty head. Controller card errors are a bit more rare, especially if it has been working before. Also, on most systems, controller errors will appear at bootup. __________ ___ / \ / / /_/ / /\/ _/ / / / __/. /__ / / / / / / / / "Happy Computing ..." / / Internet: Johnny.J.Chin@andrew.cmu.edu / ------- / 4730 Centre Ave. #412 BITnet: jc58@andrew \__________/ Pittsburgh, PA 15213 UUCP: ...!uunet!andrew.cmu.edu!jc58 Computer Dr. Carnegie Mellon University "If you don't like having backups ... try driving without your spare tire." ______________________________________________________________________________ Disclaimer: The views expressed herein are STRICTLY my own, and not CMU's.
