I attempted to format the disk numerous times with no luck. I then deleted all files from the disk and attempted to copy other files to the disk at which time I got a device not readable/disk not formatted. Explorer showed files and allowed me to open one for viewing. The first time I used the drive I inserted a disk and opened it up to see what was on it. instead of real-time helical scanning, the videotape could be duplicated linearly at high speed).I have purchased and installed Win7 on a New (2 months old) PC that has a New floppy drive. The closest to "magnetic printing" I'm aware of was the process Sony developed to duplicate Betamax tapes (i.e. Hence the floppy media can physically wear out. Unlike hard drives which have "flying heads", the read/write heads on floppy drives actually touches the media during normal operation. The tracks on 8", 5.25" and 3.5" floppies are all written magnetically by polarizing ferrite particles. However I recall from the old days that floppies had tracks “printed” on them and a magnet could mess that up, preventing them from being used. The issue is then a lack of ferrite material to polarize and generate current in the read head. worn out tracks) then erasure won't help. Maybe, if the damage is due to magnetic corruption.īut rather than use a magnet, a "bulk eraser" (an electromagnet that emits a strong alternating magnetic field) should be used.īut if the floppy has actual surface damage (e.g.
