Camera memory recovery and flash memory recovery software

Camera memory recovery with CnW Recovery software is very straightforward. For most applications the Wizard provides the simplest, quickest solution. Digital photos can be recovered, viewed and saved. It will recover deleted digital photos, as well as from memory chips that have been corrupted in a way that sometimes only a few possible photos can be seen when using the camera or PC.

To read camera memory, typically one requires a Card Reader that typically plugs into a USB port. USB 1.1, or USB 2.0 are both suitable, though the latter is much faster. The card must be visible by the computer as a logical drive, eg Drive F:. It is not possible to recover photos directly from the camera, but only by reading the memory chip in a card reader.

The wizard (automatically displayed on program startup) displays all possible drives, and once all drives have been scanned the correct memory chip drive can be selected with the combo box. The icon of the memory chip is then clicked, and the program will then try and analyze the chip contents.

Most flash memory chips are FAT16, but NTFS one can be recovered as well.

The top part of this screen gives brief details of media, and does include an estimate of files, and deleted files that could be recovered. As a guide it also shows the number of images, based on file extensions such as ‘jpg’, ‘bmp’, ‘tif’ etc

The output location should be selected on a drive that has adequate space - never try and save files onto the drive you are restoring files from.

The five options allow the user to select the mode of data recovery

• Recover good files. This will restore files in the standard way, as does the PC
• Recover deleted files. This will restore any file that is found in a directory, but marked as deleted. It is possible that the data for these files may have been overwritten. Files are restored to a ‘deleted’ subdirectory to indicate that they were originally deleted.
• Recover from directory nodes. In this mode, the whole media is scanned to find any blocks that are old directories. Files with valid names and dates are then restored. However, it is not standard for directories to isolated and so the integrity of such recovered files can not be guaranteed
• Recover unused space. This is probably one of the most powerful and useful options. It will scan the whole media and determine the start of relevant files. The files will then be stored in subdirectories based on file type, eg \jpg It does assume that all files are sequential, which for photos is normally the case. Files are restored to a ‘recovered_files’ subdirectory. The routine works largely by detecting the start of a new file, rather than the end of an actual file. Thus it is possible that the final file also includes all slack space at the end of the media. For certian file types, it is possible to detect the end, and so this problem does not always happen.
• Photographic and images only. This option is only enabled when the Restore unused space is checked. It will try and only restore image files and hence ignore any program files. This can be useful for a mixed memory stick, or hard drive.

To do a file recover, the options should be selected, and then ‘Recover now’ is pressed. The progress bar will indicate progress and thumb nails may start to appear. This function is also required in demo mode in order to get complete log, and full display of thumb nail images.

The ‘View log and files’ allows the user to see all files that have been restored from the media. Before the ‘Recover now’ function is used, the directory may not contain all file details. These details will be filled in after the restore. If a file entry is double clicked, it will be shown in a new window. Currently, this is limited to photo files, but all other files will be displayed as a hex dump.

As many memory chips will be from cameras, a useful feature is that any image files found will be displayed as a thumb nail at the bottom of the screen. The image will change every 5-10 seconds or so, and will cycle round the complete list of possible image files. This is a feature that also works on the demo program, where it is not possible to save any files to the hard drive.

One step video is a short cut for video disks. It will read, typically a mini-dvd and recover the files, and then process to produce files suitable for creating and new, standard video disk.
