I bought a 512 MB USB Jumpvault storage stick that has its software on the stick. I was able to access it as drive J: (found by accident). After installation, any attempt to run Jumpvault is met with the error: "No disk in drive! Insert disk!" or words to that effect. I had previously successfully run a floppy off that USB port. Jumpvault.com support is no help: pick your complaint from the dropdown lists, which are empty. This stick is being sold by a software house for $8.95.
