Corrupt memory card?

[TheObiJuan]

It seems that EVERY time I use my Ultra II 1GB card I get a corrupt file. For this reason I use my other 1GB card, the lexar 80x. Today I was at Enchanted Rock and did not have any more room on my lexar so I was forced to use it. I formatted the card and then loaded it.
I began taking photos and checked to see if they came up, and they did.
Later I swapped to Raw + JPEG because the sky was overexposing a bit. I got home and uploaded the pics. Most of the pics from the ultra II were not visible through any picture viewer on my computer, but the thumbnails showed up fine. All the raw files are also corrupt too..
What gets me is I was doing Exposure bracketing with a 3 shot burst, some bursts are all corrupt, and one or two had one shot make it through. ???

Is there no way to fix this or recover them? I had many great shots and to have them all ruined because of some stupid card malfunction is ridiculous!

I have had numerous problems with my CF cards and have always managed to get the files using PhotoRescue PC. It is well worth the price as it has saved me well over 200 photos.

I formatted the card and then loaded it.

to minimize corrupt files you must format the card in your camera and not in the card reader on your computer, you didn't say where you formated it. if you did format it in the camera then........ never mind.

We have received inquiries about the problem of images disappearing when using specific digital SLR cameras. As a result of our investigation, we found that the following two problems may occur. Please be advised of the details and countermeasures.

1. Disappearance of images within the camera's buffer memory
Affected Products: EOS-1Ds Mark II, EOS-1D Mark II
Problem:
Pressing the [DISPLAY] button immediately after shooting with the camera set to "RAW+JPEG (high image quality)" causes the LCD monitor to become entirely white and the camera to lock up, losing all the images in the buffer. This problem is caused by the firmware for these models and sometimes occurs regardless of the recording media used.
Countermeasure:
We are now making arrangements to release new camera firmware incorporating the correction of this problem by the end of May 2005. In the meantime, please be aware of the following when using these models.

* Before pressing the [DISPLAY] button to check captured images, make sure the access lamp is off, indicating that files have been written to the media.
* When this problem occurs, remove and re-install the battery to restore correct operation.

2. Disappearance of images when using Lexar Compact Flash Cards
Affected Products (D-SLR): EOS-1Ds Mark II, EOS-1D Mark II, EOS 20D, EOS Digital Rebel XT / EOS 350D Digital / EOS Kiss Digital N
Affected Products (CF card):
Lexar Professional 80x-speed Compact Flash cards
Problem:
Captured images on some Lexar CompactFlash cards can be lost when used with the Canon cameras listed above. Working together, Lexar and Canon have investigated the cause and confirmed that the problem occurs in extremely rare instances when the products above are used together.
Countermeasure:
Lexar will offer a free firmware update incorporating the correction of this problem by the end of May 2005 for Lexar Professional Series 80x CompactFlash card customers using the affected Canon cameras.

Lexar customers can contact Lexar Professional Support in US at (+1) 510-413-1233, or in UK at (+44) 1483-522-947 or visit Lexar on-line at www.lexar.com/support.

Try using the recovery software provided by SanDisk to recover the files. Once you have the files, do a full format of the card on your PC. Finally format the card again in-camera. Do a quick test shoot and see if you still have the problem. If so, contact SanDisk.
