I'm surprised nobody has mentioned the AppleSauce
yet. Yes, it requires a
Mac. Yes, they're currently out of stock, but Yes, it's absolutely the best
solution out there for disk imaging.

I've used it for both hard & soft-sectored 5.25" disks and 3.5" disks.
I've
also imaged a few 8" disks using it, and I know more than one person has used
it to image RX02 disks.
It'll image just about anything, including PC98 disks. GCR, FM, MFM, it'll
do it all.
