Question about floppy disks

[Oliver]

I still use 880k floppies with my miggies.  I use them for rarely played games, or system disks.  I also don't have my 1200 networked, so they get used for the odd transfer as well.  I sometimes read ebay adds out of curiosity, with no intention to buy.  Also, if the specifics of the product/sale do not match my requirements, the add will have been read with no bid.  If it's an online auction you're talking about, then there may also be people waiting before bidding.

Hmm, last time I installed Workbench 3.1, I found several system disks had died.  Damn.  I had spares, but I really should back them up.  Problem is getting reliable media to do it with.

I remember seeing floopy drive head alignment discs.  Not sure how well they worked.  Maybe it was just a case of snake oil.  Anybody tried these?
