I recently purchased a used 1Ds Mkii that is in wonderful cosmetic condition. It came without the original box or instruction manual, so I downloaded and read the manual on-line from the canon website. Everything seems to work quite well with the camera and all its functions. The problem I am having is in the image playback.....I get a big yellow ? where the images should be and when I try to download them from the memory card they show as damaged files or unsupported file types. They show fine on the cameras screen immediately after shot but I am unable to view and scroll through images afterwards. Nothing more than the big dreaded yellow question marks. I had an sd card in the camera that had a bunch of other stuff on it other than the pictures I shot. I cleared the card completely and still had the same results. The files when downloaded show as JPEG and Cr2 as they should but cannot be opened. I tired another card and got things to work OK for now...the files show with the same tags but now they are openable and useable.
I guess the question is whether the files I shot were just recorded in an un-recognizeable format or are they corrupt? I shot these pics at a wedding but was not "the photographer" for the wedding (thank God) but I would like to see if I got anything worth printing or sharing. Has anybody had similar issues as me?? Thanks for any input!
