Re: Don't knock 'em...
I have dozens of 5 1/4"from the mid 80's (Commodore 64) that still worked fine as of a couple years ago when I started pulling archive grade copies off of them.
I cannot recall what software I was using, (might have been from the Internet Archive) will have to dig it up as they had recommendations on superior 5 1/4 PC drives to use for better success rates...though my pair of 1541's still actually work as well so I could go old school and just use "Fast Hack'em II" for a backup.
Less luck with my 3 1/2" ones from the late 90's however.
