The following are some common causes of the messages. Select the scenario that applies to your situation.
Cause 1You removed a storage device from the computer after hibernation, changed the data on the device, reattached the device, and then resumed the computer.
When a Windows-based computer enters hibernation, all the necessary information such as system state and memory content to a file (Hiberfile) is stored. When the computer is resumed, Windows reads the Hiberfile to re-create the environment that is exactly same as before the computer was hibernated. Because the contents of the storage device have changed after the computer enters hibernation, the information that computer had about the volumes on the storage device is incorrect. Therefore data corruption or inconsistencies occur after you resume the computer.
Cause 2You have installed Windows 8 with other operating systems in an unsupported configuration. This issue may occur if you are multibooting Windows 8 with an unsupported configuration.
Cause 3Windows has detected NTFS file system errors. Your computer's hard disk has file system errors. Therefore, you must run a scan to fix the errors on the drive.
Resolution 1To resolve this issue, we recommend that you take the following actions:
- If you are hibernating or shutting down your computer but are also going to remove a storage device for use in another computer, you should make sure that you first remove the device by using the Safe Removal button () in the notification area.
- You may remove a storage device when a computer is in hibernation. However, do not attach the device to another computer. You may reattach the storage device to the computer before or after the computer is resumed.
