Cannot access CF card from computer
 

Hi guys,

I´m trying to install Magic Lantern on my MarkII and it needs to be done from the Compact Flash memory card via memory card reader. I´ve bought a memory card reader today and when I tried to read from the 32gb CF memory card it said it needed to be formated but it shows only like 20GB. I went to windows´ disk management where I could see the CF card was unallocated. When I´ve tried allocating it without formating it the system told me "Data error (cyclic redundancy error)". Also, when I try to format it it won´t allow me the option to use FAT.
I´ve put the card back in the MarkII and it reads it perfectly (and finds 29GB memory space).

Any thoughts?

I formated the CF card on the MarkII 3 times and it works. I think it might be the card reader that is not working properly.
Is there anyway to use the MarkII as a mass storage?

Try connecting the camera to your computer with a USB cable... the computer should recognize the card.
Also, if you have a fairly new printer, check to see if you have a card reader built in to it, many of them do these days. I forget mine even has one sometimes since I never use it...

Thanks, John. It turns out the memory card reader was defective. I´ve exchanged it for a new one an all is well :)
