Data File Not On the Removable (USB) Drive After Quicken Says It Was Successfully Backed Up
Data may be lost when a removable (USB) drive is detached from a computer and the process to safely remove the drive was not followed.
Try backing up your Quicken data file to your removable drive again. However, before you detach the removable drive from the computer, be sure to click the icon in the system tray that enables you to safely remove, unplug, or eject hardware.
Alternatively, you can backup your data to your local hard drive first, then attempt to copy the file to your removable media (USB thumb drive).
For more information about using removable drives, consult the manufacturer's instructions for your removable drive.
