I can no longer access the data on my zip disc. When I put it into the zip drive, nothing happens. The drive is able to read other zip discs that I have but the one I want. I need the information on it. Can you help?
It is quite obvious that the ZIP disk in question has gone bad. You need file recovery software like TechTools Pro, Disk Warrior, and/or Data Rescue II.
Do not futz with your disk until you have the necessary software to recover your data. Doing so with damage it further.
