Cannot open recovered files
Posted: 18 Apr 2012, 14:41
I have used TestDisk from the Win 6.14 download to copy some deleted JPG and AVI files. The files are on an SD card, and the OS on the machine used is Win7.
I have followed the online documentation, and am satisfied that the recovery process has worked.
The files have been copied, and appear to be the expected size.
However, I cannot open them.
When I attempt to open a JPG file no image is displayed. The program (Win Picture Viewer) used to open the file does not complain about the file, the image is just blank.
When I attempt to open an AVI file, the programs (Win Media Player and VLC) say the file cannot be opened. Win Media Player complains about encoding, and VLC presents an option to repair, but this does nothing.
I have also copied the recovered files from the Win7 machine to a Linux machine.
Attempting to open an AVI there, I am presented with a message saying "Failed to decode JPG". Why JPG? I don't know.
When attempting to open a JPG, no errors are reported, but there is no image displayed.
I have checked the file permissions, and all appears to be OK. I would expect a different set of issues if it were a permission problem.
Has anyone else experienced this? I am guessing I have screwed something up with the recovery, though I have read the doco, and repeated the process a couple of times and am reasonably confident that the recovery is proceeding as described in the doco.
Perhaps the source files are corrupt on the SD card?
Can someone point me in the right direction?
