What I noticed is, that formatting a floppy disk takes three times as much time for the same data amount as writing a file to the disk normally. The accoustically perceivable jumps of the head between the eighty tracks are significantly slower on a full format than on a normal write of an 1.44 MB file which matches the MF-2HD.
If I expose a floppy disk to a magnet, the data gets corrupted, as expected.
- I deleted the corrupted file.
- I tried to write the same file again.
The floppy disks fail being written to. If the write succeeds, the new data after magnet exposure is also corrupted. But the floppy disk is not physically damaged.
- After quick format: Data still corrupted after write.
- After full format: New data can be written to the floppy disk just as usually.
I would appreciate a technical explaination. I am just curious.
