JPEG digital pictures can be lost or get corrupt when opened images are
closed forcefully while terminating the image viewer or the computer
system. Abrupt power fluctuation can also corrupt a JPEG image that was
opened for editing.
Corrupt memory card or SD card, used as storage device in cameras and
image processors, can be a major reason for sluggish view of JPEG
pictures. This corruption is caused after formatting of the storage
memory.
When a user tries to open a corrupt JPEG image file, error messages
like “Unknown file format”, “Invalid JPEG marker or “File cannot be
opened” are displayed. These messages are shown due to corrupt header of
the JPEG image, invalid marker, or bad sectors in the storage device.
The causes of these issues are improper shutdown, power failure,
physical damages, and virus attack of storage media.
Precautions after Loss of JPEG Picture
To minimize JPEG corruption issues, you must keep some precautions
while handling images. Don’t do the cut, copy, paste activity more
often. Excessive movement of images in the memory or to some other
storage can cause the pictures to get lost. If your JPEG files are lost
in the mid of transmission, they may not be recovered back. Only highly
powerful JPEG Repair software tools may be able to retrieve them. This
will be sure not an economical process.
Recovery of lost JPEG images is possible by use of certain specialized
tools. Meanwhile take care not to save any more images in the memory
stick. This can cause overwriting of the area where the lost image is
stored. Not only images, refrain from storing any other type of data
file like music, video or text. When a picture or any other file is
deleted only the pointer to the file is deleted. The content of the file
remains at the same place in memory. After deletion of a file the area
is marked as free space and is available for new files. Mark that the
area is not cleaned. So, don’t save new images or JPEG files till
recovery actions are performed.
Choosing a JPEG Recovery Tool
Before buying a JPEG Repair tool
from market to recover lost photos, it is good to try the demo version
of the tool. Demo versions show the JPEG images that can be recovered
back and also show their preview. If the image that was lost is shown in
the list of the recoverable JPEG images, you can go ahead to buy the JPEG Repair software.
