I am trying to migrate some old text files off of a Windows 95 computer using a 3.5" floppy, as the old tower predates USB ports and has no internet connectivity. I can get the files onto a 3.5" floppy w/ no problem. I bought an external HP 3.5" floppy drive with USB connection to use on my new laptop running Windows 7. When I put in the diskette w/ the files on it, it sees nothing and says I need to format the disk. When I put in a new unformatted 3.5" floppy to format it, it says "Windows can't format this type of disk. Insert a different disk and try again." I am using what were standard double sided/double face 135 TPI 3.5" floppies. I've tried a couple of different brands. Any suggestions?
