Odd distortions/sections missing from a couple of frames from the Rebel XT - anyone seen this before?

[elaine_roberts1]

I got my XT in January to replace a 300D w/a broken LCD. It's worked fine, so

far, though I haven't used it a lot yet. Last weekend I shot quite a bit, and

most turned out fine, but two frames came back looking very odd indeed - see

posted pics. The distortion occurs in both the RAW and embedded JPEGs. I suspect

that its either:

 

1. A random glitch with the sensor caused by some combination of

head/humidity/flying electrons.

 

or

 

2. I've got a bad sensor and it just hasn't fritzed on me yet b/c I haven't used it.

 

So - my question is - have you seen this before, and is it a sensor problem or a

memory card problem or neither, and what's your advice? Should I contact Canon

and demand a replacement?

 

Many thanks!<div></div>

possibility 3. You have a bad CF card.

Do you format your card in-camera?

[elaine_roberts1]

Yes - I always reformat my cards in-camera after I download them. I did run into another thread suggesting that files could get corrupted if you turn off the power switch before the camera finishes writing to the CF card - could that be it?

I have similar problems with some pictures. These can all be related to a harddisk that had other problems as well. In your case I'd suspect the CF card or its formatting.

Why would i turn it off..well, just carelessness, I guess. Automatic habit to turn it off as i'm walking around, probably shouldn'tan y how.
