When i put the card in the 5dm3 the red buffer light flickers non- stop when i put any other card it flickers for about 2 sec to read the card then the red light goes out. WTF?
Possible issues with Sandisk Extreme Pro 32g CF

Formatting from my computer Actually worked. I formatted my other troubled card on the 5dm3 and it cleared up the problem also. I had to double check making sure i had backups before testing the format option. I seriously have not seen that in all my years shooting with CF cards.awinphoto said:

Doesn't matter. Wait until you shoot with them again and see if you have the same issue. If you do, send them back for replacements. Lifetime warranty.

Boseman,
Are there images on the card when you put it in? The camera reads the file structure when you put the card in, so if there are images on there it is looking at the FAT information and may take a bit to register the images, especially for a large 32gb card. Saying the card is bad is uninformed and probably wrong advice, if the card is working fine and you can copy/read files on it, then nothing to worry about.

Robert my 16 gig card flashes 1 maybe 2 sec when i put it in. These both flash prob 3min or more. When you doubt a card its hard to ever use it again best to get replacements. I personally have somewhere around 30 mem cards most from Sandisk and am hardcore for Sandisk as they never fail me. I even have Sandisk SSD drives as of recently. I remain hardcore Sandisk.Robert Welch said:

I've posted a few times before in some other threads that Convergent Design has pulled their approval of San Disk Extreme and Extreme Pro CF cards in their equipment because of a design change of the cards that has caused data errors.

I only buy Sandisk including my ssd's and never had issues. If you browse the eventspace video's from B&h there is a bloke with a presentation about memory cards. He is not from Sandisk ,but he claims they break in one of three ways. Out of the box after the first 20 uses you will know there is an issue, physical damage though the human factor and then (the scary bit) if you pull the card from a device while it is in a read/write cycle you kill it completely and cannot recover images! The latter contributes to 90% of all reported failures.

I used to use only Sandisk cards, but I got myself a couple of the new Lexar 1000X cards (150mb/sec), and they are fantastic.
Just as good quality as Sandisk, but faster AND cheaper!

With a hard drive, losing a memory block is often a sign that its dying. not necessarily so with a CF card, but you need to watch it.
Did you do a low level format in your computer? In windows, you can also scan all the memory blocks to look for bad ones, and then fix them.
If you do a scan every week for a few weeks and no more pop up, its brobably ok. If you find more bad blocks, then the card is dying. If you are in doubt, run a scan several times in a row and that will show dying blocks as well. I use Rescue 4 Pro which writes to every memory cell on the card, and marks bad ones. I've never had a bad one, so I don't know if it gives a report of which ones it mapped out.

By the way so far it has taken a month since i sent my cards in for replacement, stil nothing from Sandisk and they aren't doing anything ot expedite no matter how many times i have asked about it. Not good even if there is a good warranty program...

I'd have returned them to B&H. Maybe you still can, they have a 30 Day return. Otherwise, you can ask your credit card company if they cover a return for them. Amex provides a warranty on returning items that is good for 90 days and will pay up to $300 per item. You merely tell them you want to return it and its beyond the return date. If you tell them its defective, then they want you to use the mfgr's warranty.
