DataRescue Card Wiper
I had occasion to evaluate a potentially dodgy compactflash card recently, and thought I’d try a piece of free software that’s been sitting around on my computer for a while. The Card Wiper software from the company DataRescue - who also make the superb card-recovery software PhotoRescue - is a simple program designed to wipe clean a camera card.
But another function it has is to test such media for problems. It does this by writing zeros all over the disk, reading them back, followed by writing ones all over the disk, and again reading them back. This should be able to give a good idea if there are any “bad” parts to the card akin to a bad sector on a hard disk. Give it a try… but do note this program is designed to irrevocably erase a card - it is not recovery software like PhotoRescue.
