I am unable to use my 3.5 floopy drive. Regardless of whether I put a brand new or old floppy ( i must have 40 of them) in the drive I get the error message "Cannot copy ....(files name). The disc is write protected. Remove the write protection or use another disc." I can't even format the floppys. The tabs on the floppys I'm using are in the proper place and when I use these floppys on someone elses computer they work fine. The drive does read the floopys and extract data when asked.
