I bought this to read some old Zip disks I had lying around. I wanted to save the old files. I bought my Zip drive from third-party seller ElizabethLeeHR and even though it was used, it ran on my Win7 laptop flawlessly. No driver needed; pure plug-n-play! Of course, Zip drives eventually all develop the click-death syndrome, so I can only rate this 4 stars!
