Prologus
Data recovery is a modern industry, so new technologies and products for data recovery from modern devices are constantly appearing on the market. What's the latest? PC-3000 Portable III , which can extract information from dead SSDs on the NMVe and PCIe protocols . Recovery Explorer , which does an excellent job of recovering data from RAID arrays with not very widespread file system types, and has recently been working with it in a pair of DeepSpar Disk Imagers . Numerous and mushrooming tools for recovering information from NAND drives, the most famous of which are Rusolut ,PC-3000 and Soft-Center . All this is undoubtedly necessary, and very much in demand, and generally very cool, but ...
But it so happens that for solving a specific, current, urgent and important task, all these excellent tools are useless. Simply because the task is associated with seemingly bygone technologies for a long time. Which, meanwhile, still exist.
So the other day I had to face such a task. Floppy disk 3.5 inches. Mammoth computer technology. Data storage dinosaur. Below, if you are interested in learning about how I recovered data from a 3.5` floppy disk.
USB-FDD, which logically could read a floppy disk easily and without problems, did not cope with the task: I did not see the floppy disk (three of them were tested, and all three were helpless). So I had to "reinvent the wheel".
May the readers forgive me for this modest report, in which there is neither novelty nor any technological breakthrough, but there is only nostalgia and antique dust crumbling from ancient devices.

There were no errors inside these files, so the floppy did not even have to be re-read - everything was counted correctly the first time. They knew how to do it before!
