 Here are some example flux recordings so you can see how the visualization differs between various floppy data formats. In addition, note that the metadata fields change depending on what is selected in the Platform pulldown. This is to help you identify dependencies frequently encountered on each computing platform. Here are some example flux recordings so you can see how the visualization differs between various floppy data formats.

-  * Below is an example of a poor quality 800K Mac HFS disk. There are two points in time represented. The first image shows the output of the display as the first pass is being completed, at 1:10 elapsed. In the left-hand, Side A visualization, note the red and yellow indicators around the 8 o'clock position. Then in the second image, at 4:00 elapsed, note how many of the indicators in the 8 o'clock spot have turned yellow or green after Applesauce has made several attempts to recover the data.+  * Below is an example of a poor quality 800K Mac HFS disk. There are two points in time represented. The first image shows the output of the display as the first pass is being completed, at 1:10 elapsed. In the left-hand, Side A visualization, note the red and yellow indicators around the 8 o'clock position. Then in the second image, at 4:00 elapsed, note how many of the indicators in the 8 o'clock spot have improved to yellow or green after Applesauce has made several attempts to recover the data. Since this disk is not copy protected, attempting to recover the data using the Fast Imager would probably prove fruitful. The Fast Imager would allow for more attempts at re-reading the difficult sections of the disk. Also, the Fast Imager would allow attempts to recover the damaged sections with several different drives, where some drives might do better on certain sectors than other drives. Finally, a disk like this should be inspected under magnification to look for dirt or mold. A solid cleaning and/or a drop of cyclomethicone might render this disk fully readable.
