Under the following conditions, data that is written to a removable media storage device may be deleted from the device:
Your Windows 2000-based computer hibernates while a removable media storage device is inserted. Removable media storage devices may include Compact Flash, Memory Stick, SmartMedia, or Secure Digital memory devices.
You remove the media, and then add data to it.
You reinsert the media into the computer, and then resume from hibernation.
The data that was written to the device while the computer was hibernating may be missing when you insert the media into another computer or device (such as a digital camera).
This problem may occur when Windows caches the original data on the device while the computer is hibernating. Windows restores this original data back to the device when the computer resumes from hibernation.
