Zip disk problem ...

Try to get the "tree node" message back up again and copy it word-for-word. Then place this message in quotes and google it. Add the words '"zip disk"' 'open' and 'Mac' to the search.

It's too late to mention that you should always back up important data in case something like this occurs. We never think to fix a leaky roof until it rains and then when the storm passes, we sit back, relax and think to ourselves "It's not raining...I don't need to fix it right now". GUILTY PARTY...Right here!

A tree on PCs is a hunk of directory...such as J:\images\portraits on my computer is a tree. Everything in the portraits file, including subfolders, is part of that tree. J:\images is also a tree, and all folders in that tree, including the portraits folder is part of that tree. And, of course, the J:\ tree includes everything on the J drive. "Tree node" might be mac's term for the tree branch, or that particular folder and its contents. It sounds like a folder or file might be corrupted. This can happen by simply storing it on a speaker, television set or near a magnet.

I apologige if I sound oversimplified...It's because I'm used to helping people with very little knowledge of the computer. And in this case, I may not be helpful at all. Sorry.

 

You might be sure the door on the disk slides smoothly, and that the disk in the center turns freely.

 

One other thing you might try if you don't get it to work is to try it in someone else's unit and see if it might work enough to save your data to their hard drive then transfer it.

I don't know if they write to disk the same as pc zips or not (doubt it) but if you can find out that they do you might try it on someones pc drive.

Also, there are services to regain data from hard drives that have crashed, there might be the same for zip disks??? be worth a look around.
