Compact Flash Cards

The lexar card I had was a Pro 133x 2GB and it was used (and gave problems) in a Canon 1DMKIIN body. I have never had a repeat of this with any Sandisk card.
Perhaps, having since updated the firmware in both of my cameras I should ask for my card back off my mate, but with my living depending on my pics I'd rather not take the risk.
