Intermittant ERR 70 -- 5D Mark III
Mar 25, 2012

Just as an FYI, I have had a few intermittent ERR 70's when reinstalling a flash chip after download from a Lexar card reader. It can be fixed by reformatting the CF chip from the computer.

I have tried a Lexar 16GB CF and a Transcend 32 GB CF. Both exhibit the same symptom and can only be fixed by reformatting the CF from my pc.

Interestingly, I can take the "bad" CF and put it in my 7D and it works w/o error, yet reinserting it into the 5DM3, the error 70 occurs.

It's a rather strange problem and intermittent, so I can't always replicate it.

If/when I can "noodle" the problem down further, I'll report back with more info.
