To my surprise I discovered today that FREESCO was still releasing updates all the way until 2014.
My big secret for those of us still using floppies (USB floppies are a steal!) --- get Maxell NOS; they're about $3 per diskette now, but I have beat them hard and they keep going. Of course, I also had a batch of poorly-stored floppies that would not even turn (!) from one vendor (cheap, tho...) and they almost ruined one drive.
My rule now is: once a single sector goes kaput, make a new working copy from your backup (you HAVE a backup, right???), mark the bad sector of the failed disk, and put it in the 'BAD' pile. I have not yet had a sector on a Maxell 1.44 diskette go bad. Several SONY diskettes however are in that pile.
Note that the head drags on the surface of a floppy, so you're always losing a little; what that closeness does, tho, is allow phenomenal bits-per-square-inch. The coatings are very good, binders are good, magnetic properties are excellent. And the head widths (both sides, after all) are small. So you get formatted 80 cylinders of 18,432 bytes per cylinder MSDOS-compatible capacity, at that 5 revolutions per second ( 300 RPM, but gosh, RPS is a better unit here...) speed.
The floppy drive is an incredible chunk of engineering. It's unfortunate that Zip 100 and Zip 250 arrived so relatively late in the game.
:-D
Iomega's awesome Zip drive disk (100MB, 250MB, 750MB capacities) , I think I still have a 250MB zip drive somewhere in my home attic.
They required a dedicated zip drive (took up same sized slot/bay as a floppy disk drive), but (if I recall right) that drive was backward compatible standard 3&1⁄2-inch 1.44MB floppy disks.
Interestingly, these drive also came in variants to work with different types of interfaces: IDE, ATAPI, USB, SCSI, FireWire.
Zip drives filled the portable storage niche, until CDs and DVDs replaced their need.

I found it cool that floppies and superfloppies had label stickers on which we can write (with a sketch pen) to remind the user of what content the disk is intended for.
There were some nice cameras that used Zip disks for storage! Very convenient for photographers working on multiple projects or sessions.

One of these was used to load the microcode into the VAX-11/780 upon boot.
Building an RT11 system disk onto an RL02 off another RL02 made the downstairs neighbours complain quite a lot, even though the floor slab in my flat was about 40cm thick concrete. They didn't muck about with these 1960s tower blocks but it was no match for a pair of pint glass sized head actuators and a pair of washing machine motors.
