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.

Brief, practical follow-up for anyone who sees a "no disk" error when launching a program from a USB stick. Thanks to for the report and to and for the suggestions already posted. That error is most often triggered when an application tries to open a drive letter or working directory that Windows currently considers "no media" (or when a shortcut/start-in path points to a missing device).

Useful, actionable checks and fixes:

  • Open Computer Management -> Disk Management and confirm the USB volume and its letter. Right-click the volume -> Change Drive Letter and Paths to assign a stable letter (avoid A: or B:).
  • Inspect the program shortcut: Right-click -> Properties -> "Start in". If it names a drive that might be absent, change it to the program folder or leave it blank.
  • If the app was run directly from the stick, copy its folder to the local disk (C:\Program Files) and run or install from there; portable stubs often expect files in a fixed place.
  • If diagnosing deeper, run Process Monitor (Sysinternals) and filter on the program name to see which path returns "NAME NOT FOUND" or "NOT READY" — that reveals the missing drive/path.
  • Check Device Manager and try a different USB port if the stick does not appear in Disk Management.

The symptom reported by (working after launching from another program) is consistent with a working-directory or path lookup issue rather than a hardware fault. For a durable fix, give the stick a permanent letter or install locally. Avoid registry changes unless comfortable; back up before editing.

Does it need drivers?

No, but thanks. Jumpvault suddenly started working! My Active Word program asked if I wanted to create a hot word, so I took "Jump" and it loaded and ran without the disk question. Go figure.

It's possible that the fact that you once used a floppy drive there caused Windows to query the drive "is disk loaded?" Of course, since it has no removable disk, the stick didn't know how to answer the query.

Go into the device driver menu in Control Panel and check the settings.

It's possible that some piece of software has its own memory of a floppy drive being there, and is somehow imparting this wrong info to Windows.

Thanks. It's running. I looked at Ctl Panel, and did not see device driver anywhere. The new CP with its categories is kind of dumb. But there is a Classic View tab that puts all the icons out. Closest I came was to Add Hardware and I replied It was Installed, and got a long dropdown list of numerically coded hardware. I did not see the stick there. Thank you anyway. BTW I haven't tried to see if the floppy will work again, and I have yet to back up a file. Jackpol
