RAW image file (CRW & CR2)
Camera raw image files, also known as digital negatives, contain
minimally processed data from the image sensor of either a digital camera,
image scanner, or motion picture film scanner. Raw files are named so because
they are not yet processed and therefore are not ready to be printed or edited
with a bitmap graphics editor.
CRW is Canon Digital Camera Raw Image Format. This format is for
some earlier Canon digital cameras. It
has been superseded by CR2, however. Raw files can contain text information about
the picture and conditions in the camera when the picture was taken. So, raw image files are very important
for digital camera users especially for those enthusiastic/professional photographers.
Main Reasons of RAW Files loss need to be Taken Care of
Human Errors This
is a very common factor which leads to raw image files loss. You attempt to
preview or do other operations, but delete them from SD card, camera, PC, etc.
unexpectedly. Or one moment
you abandon them and then delete them, but next time you realize that these
deleted pictures deserve your attention.
Transfer Issue If sudden power surge happens while
transferring pictures from digital camera to PC, you may suffer RAW files loss.
Disaster may also happen to you if you disconnect digital camera/SD card with
PC while data transfer/process is ongoing.
File System Corruption Corruption to the file system in hard
disk / memory card leads to inaccessibility and in turn results in data loss
which contained your RAW image files. Corruption happens in many situations,
such as virus attack, switching off camera / camcorder during file transfer,
etc.
Unwise Format Sometimes, you’re forced to format
your drive /partition or camera from the system containing your RAW files by a
message like “Disk needs to be formatted”.
