Thanks.  I didn't know that but it wouldn't do me any good since I shoot 
only raw.  Perhaps Canon raw files have a suitable end-of-file marker as 
well but the recovery software I tried (two varieties, RescuePro being 
one of them) did recognize the start of images but failed if images were 
not sequentially located.
