Sometimes it happens that all image files (JPEG, PNG, etc.) and videos (3GP) are erased automatically in the SD Card. So they are removed from Gallery also.
This means I risk to lose documents and photos I shoot with the phone camera, unless I make external backups.
I noticed that sometimes it looks related to fast mount/unmount cycles via USB cable to a PC (due to unwanted multiple pressure on the 'Activate/Deactivate media archive' soft-button on the phone)
Does anyone know what happens? Is it a known bug, some misuse from my side, etc.
My phone model is LG P962, with Android 2.3.4 and a 32-GB SD Card.
