I have been traveling for a while with my G4 and have been backing up important data religiously onto a 1GB memory stick.

When I tried to do this today all I get is a screen that says:

"Disk Insertion

The disk you inserted was not readable by this computer."

The screen then gives three options:

"Initialize Ignore Eject"

I clicked the latter two without success. (The memory stick icon does not appear.) I will not click the first one for fear of deleting everything from the memory stick.

The memory stick is far from full, and I have been using it every day for several months without any problem. The data that is on it is very important.

Any suggestions on what has gone wrong or what I should do would be much appreciated.
