MSDC Mount Error typically occurs when a device fails to properly recognize or mount an external storage medium, such as an SD card or USB drive. This can happen due to file system corruption, improper insertion, or hardware issues. To rectify this, users can try removing and reinserting the storage device, using a different card reader or USB port, formatting the drive (after backing up data), or checking for hardware faults. If the problem persists, it may be necessary to replace the storage device.

The "MSDC" message on your Vivitar Vivicam 8025 indicates that the camera is in Mass Storage Device mode, which typically occurs when it's connected to a computer or when there's an issue with the memory card. To resolve this, try removing the memory card and reinserting it, or ensure the camera is not connected to any USB devices. If the problem persists, you may need to reset the camera or format the memory card.
