today funny application from linux floppymeter
Just added floppy to my borkstation

man floppymeter
floppymeter - measure raw capacity and exact rotation speed of floppy
drive

and some benchmarks :)

floppymeter
Warning: all data contained on the floppy disk will be lost. Continue?
yes


- rotations since start of test = 1000
- average time per rotation since start of test = 200062
- sliding average of the last 10 rotations 200197
- missed rotations 2


capacity=200153 half bits (should be 200000 half bits)
time_per_rotation=200062 microseconds (should be 200000)
data transfer rate=500227 bits per second (should be 500000)

deviation on capacity: +765 ppm
deviation on time_per_rotation: +310 ppm
deviation on data transfer rate: +454 ppm

Insert the following line to your /etc/driveprm file:
drive0: deviation=765
