The vault is find for things that need to be secure: resumes, legal documents, medical records. But people frequently try to put everything into it: movies, music, hard drive backups, etc and it fails. It wasn’t designed for that type of use. Those things can be stored on the drive fine, just not inside the vault.
With the flash drive removed, reboot the laptop, then insert the flash drive. See if that helps.
RIGHT click on the My Computer icon, then select Management. Then select Disk Management. Does the flash drive show up in the Disk Mgmnt screen? If so, what does it show up as? Then Right click on the drive and see what it shows.
So I am doing this at my computer at work - a windows 7 desktop.
Disk manager does not see it, however it does show up on the device manager.
It has always shown up on the device manager whenever I have checked, but it cannot pupulate the “Volumes” window - it gives the error “Volume information for this disk cannot be found”. What is also interesting is that in the general tab, it says “this device is working properly”! Go figure.
