I PURCHASED a thousand floppies from different sellers. All that I have tried, turn the computer off and it restarts, It will continue to restart until the floppy is removed. Most of these are CALLED "ecodisk". They are grey in color.

I store information on floppies everyday and have recorded hundreds of floppies on this computer . It works for all kinds of brands, but for some reason it won't work if the floppy is grey.

This is a Sony Vaio - Windows XP.

If your reply includes how backwards I am, or you just want to know what I'm doing DO NOT reply. If you ACTUALLY have some information - then please help.(Not sure if I know anyone who would think of buying 1000 old 1980's technology, but okay) (and no, thats not an insult, but consider BETTER storage OPTIONS if you plan on storing lots of data)

Go to My Computer, right click the A:\ drive, and click "Format"
Use the default options.
This will destroy any existing data on the floppies. more info on your computerWow that's a lot of floppies. Just out of curiosity... why do you need that many?

But like unlovedwarrior said we need more info.
The computer's specification would be good to know along with what VERSION of windows you use.It is unlikely to be all the floppies are bad if someone else can format them. It is more likely a problem with the floppy drive you insert them in.

What happens if you insert one of the disks you had formatted in the floppy drive? Does it stop the computer? Can you see the it in 3.5" drive under MY Computer?

What version of windows are you using ? What spec. is your computer?
