Possible issues with Sandisk Extreme Pro 32g CF

[Bosman]

Let me tell you who is at fault, me. As much as i want to keep this to myself, i'll explain what happened. I named the two 32gig cards i bought so when i plug them into the computer i saw something like SanDisk 32g cf 1,SanDisk 32g cf 2. I thought since it is high end memory there wouldn't be issues. Wrong.
By the way it took a little more than a month and multiple times contacting them before i got the replacements, and interesting, they no longer have a gold stripe but a silver one on the CF. They are still extreme pro 32gig but silver. Either that indicates new ones are coming out and these older ones are silver or this is how they tell the new batch of cf cards with new memory...I don't know, just a guess.

Naming them might do it, Canon looks for their own name. However, I've popped Nikon Cards into a Canon Camera and vice versa, and formatting merely renamed them to meet the Camera specs.
You can run a chkdisk on a card to see if it finds any bad sectors (Windows). it will check every block, so it takes several minutes. That does confirm the integrity of the card.
