Re: OT reading Canon 5DII cards
I talked to a friend last night with a 5DII, and he said he had no trouble getting his mac to read the cards. I booted up my linux box this morning, plugged the card in, and it just worked. The card is a Super Talent 600x 64GB compact flash http://www.supertalent.com/products/sd_detail.php?series=CompactFlash%20Cards http://www.supertalent.com/datasheets/5_116.pdf My card reader on the Mac is an IOGEAR GUH28R http://www.iogear.com/product/GUH284R/ I am beginning to suspect the card reader as the problem link.

Re: OT reading Canon 5DII cards
Could just be the reader. I had an old CF card reader bought back in 2001, and when i set the iMac up in 2010, it would not recognize the reader or card. My newer reader, 2008 did fine.

Re: OT reading Canon 5DII cards
A quick bit of research gives me two obvious sources for your problem. There may be more but these should be easy to identify or eliminate. The first is that the CF card could be a CFast card, designed for extremely fast read/write speeds and needing a card reader cabable of the specification. Second is the file system of the card. FAT32 file system can only create or read a single file up to 4GB minus one byte (now I know why my GoPro video files get split into multiple smaller files for a single long shot) and if your friend shot video with his Canon, or wanted to future-proof himself for the possibility then the card or its filing system could be beyond FAT32 spec. So, have you tried connecting the camera to your iMac with an older/smaller CF card that is definitely FAT32? If it's a card compatibility issue, then your friend would have already catered for the problem, but you apparently haven't. regards, Anthony On 17 November 2012 17:20, Larry Colen l...@red4est.com wrote: The widow of my friend who passed away from cancer last year asked me to teach her how to use his Canon 5DmkII.

Re: OT reading Canon 5DII cards
I might want to add to that the being pin-based, the mechanical coupling of the card and the reader is rather fragile. Even minimal bent of one of the pins in the reader, and you may have incomplete interface thereby causing the card to malf.

Re: OT reading Canon 5DII cards
Larry, A few thoughts: 1. Either, as Boris wrote, you've got bad/bent contacts (very often with CF readers), or the reader is not designed to read this higher capacity cards. 2. Typically, when you connect a digital camera via USB, at least two types of drivers have to be activated: first - for the connection, and second, - for the mass storage device. It looks like the second one is not there. I don't know about Canon DSLRs, but smaller, PS digital cameras from Canon don't work with the generic devices for that (at least under Windows) but require a special driver to be installed before the system can recognize them as a storage device. In the absence of the driver, only software programs that know how to work with cameras would be able to read the content of the camera's storage.
