TL;DR: I have a video at the bottom of this page explaining my issue visually with annotations if my text is too hard to understand or if you don't want to read a wall of text!
I've gone and collected a ton of floppy disks lately, including buying job lots of 50 used disks and even new disks still in their packaging. But most of the disks I use which are used seem to be completely dead. Is this common for floppy disks? It's very odd that the same make of floppy disks vary in the amount of life they have even if they have been manufactured in the same year.
The reason I find this odd is because some of the white disks are working, and some of them aren't - it seems that the ones with the write protection removed such as the Windows 3.1 or DOS disks are having the most trouble, whilst the other disks which are quite related such as the Soft Windows (even then some of the Soft Windows disks don't work - which confuses me more, as surely the related disks in different parts should be damaged due to old age too then - which makes me think it's not due to old age), Lotus or HP disks are working flawlessly (I've posted a video below for a clearer explanation)
The new disks in question were still in their packaging, 50x white diskettes, formatted, unlabelled, untouched, clean...yet not a single one working - granted they were probably ancient but I do not see how floppies would die so easily and start choking a drive - what is causing this by the way? Is it really the age? Any detailed answers or good explanations are greatly appreciated as well as more chance of getting chosen for best answer
I have a video here showing the disks and how almost related they are to each other, but some disks don't work in a pile and some do work. Is there a way of recovering these disks or fixing them? As I've bought so many (which I can quite easily return for a refund, so no need to worry about that - but just seeing if there's a way first) I want to know if there's a way I can possibly fix them first. I've used the non-working floppies in multiple machines such as a typical office Dell desktop and a Compaq Prolinea computer - they come back with formatting or cylinder errors also
Anyway here's the video - please watch it before making your answer to ensure you understand my issue precisely before just writing something non-constructive or uninformative to me: http://youtu.be/jBXsRYvGL4g
Hope someone can shed some light or let me know what can be done!
