Will the card appear on your desktop? If so, there are some data retrieval programs that are supposed to work quite well. I have never used any of them, but a quick internet search should turn them up for you. As I understand it, data is often retrievable even after you have re-formatted the card. Good luck.

Before you touch the card in any way i'd suggest that you try another card reader as problems come often from the latter.

well the files aren't showing up on my camera (as mentioned) so i don't think it's a reader problem

If you can try another reader do it first and think afterwards 
Otherwise see www.cgsecurity.org

used cgsecurity and it rescued the files however they are all very, very small and basically unuseable. all of them were originally tiffs... when i open them in cs they come out as 72 dpi at 2.2 x 1.6 inches. 8 bit tiffs????
any ideas???

How did you get Tiff files on your card? Did you use it with another camera? Anyway, you might wish to try TestDisk in the first place:

they're not tiff's on the card... i believe the software is converting them to tiffs from epson erf's... sorry if i made it confusing. the software doesn't recognize erf files it appears

Since you have a Sandisk that is giving problems, what about this (LINK) program from Sandisk? There is a demo version. I've not had to use it, and so I don't know if it'll help.
On on another page (LINK) Sandisk writes,
"As a valued SanDisk customer, we're passing along a special discount on this software which can be purchased by clicking the link above.
Please use this online order code, SNDK-RP-1203, to receive the discount on the software. Additionally, SanDisk offers file recovery service at a discount through LC Technology, and more information can be found on the same link or by calling 866-603-2195.
RescuePRO is a recovery solution for digital media. It recovers images, documents, mail, video, music or just about anything."
May be the demo will do the trick without having to come off the hip with any cash.
Take care,
Michael

I am a computer consultant, dabbling in cameras and photography. There are two significant problems on flash memory devices. One is the type of USB port you plug into, and secondly, ARE YOU TERMINATING the USB device before removing a card. My experience has shown me that there is a critical problem with the power that the USB port introduces to flash memory devices in order to power the memory.
Without going into more detail than this posting situation allows, the first problem is the use of flash memory devices, ie thumb drive, camera memory cards AND PERHAPS even your digital camera when plugged into powered hubs that use an AC wall adaptor to power the hub. I suggest that you never plug a flash memory device into this type of hub. Only use ports on the computer. If you must use a hub to expand the capacity of your computers ports, use a passive hub.... no AC adaptor plugged into the wall.
I've personally destroyed two thumb drives and one memory card before isolating the source of the problem.
Now, there is one other problem. Usually when you plug a flash memory device into your computer (XP or Vista), the operating system discovers the device and powers the port into which the device is plugged. Often, there will be a USB telltale in the System Tray (Lower right hand corner of your screen). The telltale looks like a little grey card with a green arrow above it. That's the system tray item indicating that you are using an external USB device. If you hover the cursor over that card/green arrow, you should see a message that says safely remove hardware. This message is important. The USB port must be turned off before you pull the memory device out. Otherwise, if you do not turn off the port, you may create a slight spark when pulling the device and permanently damage the memory card (AND I wonder,,, you camera if linked directly to the computer?).
To disable the port you double left click on the grey card/green arrow. It opens a dialogue box, in which you pick or select the drive you want to remove and then click "stop". You will then be advised that it is safe to remove the card.
In some cases, where intervening devices are use, such as printers with media ports, you may not get this telltale and control symbol.
I contend that your memory card MAY be damaged beyond repair. Can you re-format it? Even if you can, I do not think I would trust the card.
I've encountered this problem personally and on client computers. I also saw it on a 160Gb external hard drive that could no longer be used. In this case the client was using the external hard drive for his "scratch" disk in Photoshop and doing editing over the USB 2.0 cable. USB 2.0 is not nearly fast enough to be the working drive for image editing. The drive was destroyed. Fortunately, it was replacable under warranty since it was a Western Digital and less than 6 months old.
You have to be careful on USB. Never remove a device without shutting off the port first.

Re: my post above. There is also the question of using ports in a laptop. Often laptop USB ports, when running on battery, do not generate enough power out of one port to power an external hard drive. Usually, the USB cables that come with external drives have two plugins on the computer end, to use two ports. If not that, they usually have their own AC power supply. With this in mind, and the validation that laptop USB ports may be underpowered, I do not know if flash memory drives have a unique problem related to laptop/notebook computers. Food for thought?

Your recovery program is "rescuing" the small embedded jpgs in your ERF files but doesn't know how to recover the whole RAW file.
If you didn't overwrite the files on the card, they are still there.
