Enough to suck diskettes

I had about thirty old floppy I wanted save the contents before disposal. The player is recognized by my computer (Linux Fedora 17 amd64). There are some disks that I could not read, but it is not possible to know if it is the reader malfunctions or floppy disks that were dead.

One drawback that I found: the reader continues indefinitely to make noise even when we do not read / write operation, and also makes noise when there is no floppy. So I would not use it for daily operations. Who uses floppy disks daily?
