hey- All you need to do is "Quick format" the disk with the CAMERA rather than the memry stick plugged into the computer drive.

My 128MB memory stick receives an error C13:01. Can't read in any memory stick device, either digital camera or read/write device. Please Helpppppppppp.

did you find a fix? I have pictures that I can't copy off the 128K stick. I was able to print them -- on a HP printer -- it saw them to print, but not to copy. What can we do?
