This item is supported on Windows 95 and earlier operating systems :( I bought this to transfer data from old disks only to find that this device isn't supported on anything later than Windows 95. Iomega has gone belly up and any support links take you to the Lenovo website. This zip drives also come with USB connections, but I haven't had good luck with those models and they break easily. That's why I bought the older parallel port model. This one worked like a champ back in the day and I subsequently replaced it with a USB model for 250MB disks. Also, just as any FYI, the 250MB zip drives will read the 100MB disks, but the 100MB drives will not read the 250MB disks.
