Plenty of people have reported that this works (for a time), so to declare that it never works is simply incorrect. I've used this hack myself with short-term success.

As I posted, you can still order the right disks online. And as of a year ago, Office Depot offered them as a special-order item, for instance.

Absent that, another option is to degauss a 1.4MB floppy before using the tape hack. That worked wonders to increase yields for me. But again, this was only for a short term. I would never trust this trick to work over the long term.

But as equill said, there are ways to bypass this hassle altogether.
