If your CompactFlash card refuses to give up your precious photos, Picture Rescue can help.

 

Magnets eat volatile storage devices such as hard drives and Microdrives for lunch, but nonvolatile media cards like CompactFlash are generally safe. Prolonged exposure could eventually have an effect, but we stuck a 1GB Lexar CF card to a handful of powerful, rare-earth magnets and lost no data.

 

If you're experiencing problems getting images off a CompactFlash card, however, Prosoft's Picture Rescue ($59, www.prosofteng.com) has worked well in our experiences with corrupt flash-memory cards. Oh, and you may have heard about people getting data off of recalcitrant hard drives by freezing them or baking them - but don't try that with your CompactFlash card (or any memory card, for that matter). The reason that those extreme techniques occasionally coax a hard drive back into action has to do with the mechanical parts of the hard drive - parts that no memory card has.

 

FYI, the most common (and most lab-repeatable) cause of media-card corruption is removing the media while it's busy saving or transferring data. So never remove a media card while it's uploading pictures to your Mac, and try to charge the camera's battery before it gives up the ghost, lest it croak while the camera is writing images to the card.
