In October 2011, Lenovo released and preloaded "RapidDrive Advanced" software to help users that have both an mSATA SSD and an internal HDD. The software was designed to help users migrate their desktop, downloads, and library folders from the small mSATA SSD to the large HDD. Unfortunately the software has some issues that may result in your files being moved to a removable device such as an eSATA or Ultrabay HDD.
At this time, Lenovo recommends uninstalling "RapidDrive Advanced" software to prevent possible unintended behavior of the application.
1. To know whether RapidDrive Advanced is installed on your system, type "RapidDrive Advanced" into the start menu. If it is not found, then the software is not installed and no further action is needed.
2. To know whether RapidDrive Advanced has moved your desktop, downloads, and library folders, run "RapidDrive Advanced" from the start menu. When the application loads, look at the right-hand panel under "Large capacity HDD drive". If it says, "Your system is currently running in a reduced capacity mode", then RapidDrive Advanced has not yet activated and your system is at risk for potential future data loss. Lenovo recommends to immediately uninstall RapidDrive Advanced following the instructions at the end of this article.
3. If RapidDrive Advanced says "RapidDrive Advanced has automatically placed the following user libraries and folders on the HDD", then it means that your desktop, downloads, and libraries have been moved from your SSD to another device. If you know where your files are, and you like the configuration changes that RapidDrive Advanced has made, then you may consider keeping it installed. You are not at risk for potential data loss in this case.
To uninstall RapidDrive Advanced:
a. open the control panel
b. click on "Programs" and then "Uninstall a program"
c. in the list of installed programs, click on "RapidDrive Advanced"
d. click on the "Uninstall" button and follow the on-screen prompts to uninstall the software.
