Question about Canon EOS 400D / Rebel XTi Digital Camera
My canon xti had the same reading cf card error 99.
Since my camera is out of warranty. I had to find a way to fix it. After reading all possible solutions in this site, I looked at the pins (that used to connect to the CF card) and found out that one pin in the middle bent. That caused the problem. I used the tiny screw driver to bend that pin back to the original position. Inserted the card back and it worked. I felt so happy!!!! (Please make sure to have the battery removed while fixing...to be saved.)

Canon have a few different ERROR codes (eg ERR01, ERR02 etc) BUT if there is any other fault with the camera that is not covered by them it comes up with ERR99 (vaguely saying ANY other fault!)
Some of the problems above may be the CF card holder pins being damaged - Have a look in the holder if you can, there are longer pins at each end & the middle, they are the ones that show any damage first. Needs to go to a repairer for that one !
Some of the problems above could be down to the cards being formatted on the PC. Always best to use the camera to re-format the cards. Sometimes the PC can re-format the card with the wrong configuration causing the ERR99.
Hope this helps someone

Usually 99 error means a problem with the lens, try to change the lens, or connect it all the way (i.e. until you can turn it anymore). I had a Sigma lens that didn't work with my new digital Canon. it also gave me 99 error and then 2 months ago, a canon lens gave me the same problem, check the lens.

This is a broad error for hot shoe issues and the lens electrical contacts. People have complained about this and it was never related to the memory card. The most common cause for this error is the lens contacts though. On the body, being very careful - check the contacts for oil or dirt. You can take a clean pencil eraser and gently wipe the contacts (making sure not to let shavings or anything get into the body!). Do the same for the lens and try it out. Many people have reported success after this process. Good luck.

I sent it in for a repair to canon, came back good as new with no charge.

I recharged the battery to full capacity. Still, the camera still reports a code 99 error on all CF cards. I'll bring the camera in to work with me tomorrow and call Canon for warranty service. Unfortunately, this means I'll miss photographing the lunar eclipse tomorrow night. Oh, well!
