I just shot a whack of pics at my son's hockey game this morning and at the last pic I got the red screen of death on my CF card - corrupted card.
I'm using an 8GB Kingston CF card. This happened a few months ago as well, but I had only taken a few pics, so I did a reformat and its worked fine since then.
I've been able to pull some older pics off the card (from Dec) manually on a windows XP machine, but the card can't be read from a card reader on my Mac.
When I check the card drive on my windows machine it shows 4.5GB of data used on the card, but only about 30 pics are available.
Are there any free recovery programs that can help me access the hidden/corrupt data on the CF card?

Been several threads on this before. Not sure what search parameters to use.
None of my 5 digital cameras have ever corrupted a card when the battery was low. That includes Olympus, Canon and Kodak models. They will refuse to work. I wonder if perhaps the problem is related to the computer also writing to the card.
One thing I am very careful about is locking the card when transferring images to any computer. Once images are transferred, backed up and the integrity of the back-up images confirmed; I then format the card using the camera not the computer. That way only the camera writes to the card. Also formating the card ensures the camera is always writing to contiguous space as I also do my sorting, selecting and deleting on the computer.

ImageRescue3 used to be free from Lexar. Now that version 4 is out it seems to have disappeared. Maybe google for imagerescue 3 to see if someone still has it available. PM me if you don't have any luck
Thanks Folks!
Used an older version of ImageRescue on an older windows machine pulled all 649 together! Time to invest in a good mac rescue program for the future.
I appreciate the help and suggestions.

As this is the second time this has happened with this card/camera, I would google to see if your particular camera model is known for this issue. As I said previously with a low battery most cameras will simply shut down but not corrupt the card. There are exceptions and if your camera is one of them you will need to either replace it, or learn to replace or charge the batteries before they are depleted.
This may not apply to the OP but some user discretion is also required. Yes after the camera shuts down once you may be able to squeeze an extra image or two out of the card, but at the very least you risk losing the image and possibly, as you have proven, an entire card load of them.
For those that use AAs; I have found that NiMH rechargeable AAs degrade quite quickly after about a year of alternating sets in my camera. One camera went from; going 6 weeks on a fresh charge to going less than a week. I still use NiMHs but they do get replaced once a year and I always have fresh AA alkalines just in case the day is longer than the batteries capacity.
It is also possible card is iffy. Maybe time for a replacement?
As previously mentioned do take steps to ensure that your computer does not write to the card and use your camera to format the card after downloading images. I know one individual who liked to keep his best images on the card, erasing only the surplus images via his computer. Made it easy to show images to his friends. On at least two occasions he lost images and finally was persuaded to abandon the practice.

It is also time to toss that CF card and buy a new one...
Glad you were able to get the files off your card with ImageRescue. If this is the second time that you have gotten a corrupt card then its probably time to stop using it and get a new card. If the Kingston card has a lifetime warranty you may want to get hold of Kingston and ask for a replacement.

In my experience the best solution for the NiMH battery issue is to switch to the Sanyo Eneloop extended life batteries (or 3rd party batteries from Sony, President's Choice and other brand names). They hold their internal charge for much longer than regular NiMHs.
I've also had super performance from disposable Energizer lithium batteries in my old Pentax DS and K200D (often on the order of 1000 shots between changes). Faster recycle times in flashes as well

Single most important piece of advice on the subject...highlighted in blue. Knock on wood (or a reasonable facsimile), I have never had a CF card go bad on me yet, but then I always follow the above and delete/format/etc. in camera only. Also, only use Sandisk media, Ultras or better. Based on reports, Sandisk seems to be the most reliable and recoverable if something should go awry.

I am currently about 10 months into a set of Rayovac Pre-charged, supposedly holds extended charges. So far each pair continues to hold its charge for at least a month depending on the number of pictures we take. Probably the same battery as Kami suggested.
The Energizer rechargeables I used to use would probably be lasting perhaps 10 days at this point.
