The camera refused to reformat the card so I took it to the Mac reformatted it there and then back to the camera - second time around it reformatted it OK. However now and again when switching on it still says the SD card is damaged and I have to reformat it again (in camera). This has really put me off upgrading my firmware.
SD cards are relatively cheap. A lot cheaper than having to have your camera repaired.

I think you should get a new/different card to use for your update.

Canon 60D, EF 50 f/1.8 II, EF 85 f/1.8 EF-S 10-18 f/4.5 - 5.6, EF-S 18-135 f/3.5 - 5.6, EF 24-105 f/4L, 430 EX II

Pentax K1000, A50 f/1.7, M135 f/3.5, A70-210 F/4

I've never had any problem with the card and it's only a few months old (Sandisk 3 Extreme). I doubt it's the card but I'm very suspicious of the firmware having being corrupted during the download somehow (twice) !

I had this problem with XD cards, they would just randomly corrupt for no reason, after a format they would be fine for another 6-odd months.
