Ugh, this is confounding! What a conundrum! Explicitly contangled, confused, con--something. Whatever.
Two days ago, my Internal Card Reader decided to not want to read ANY of my 8GB CF cards. Tried my 32GB CF card. No worky. Plugged in my old 4GB card. Works fine.
All cards are Kingston 133X elite pro (yeah yeah...). However, that's four cards I tried, 3 of which do not work. However, all cards have been formatted in-camera. Windows 7 x64 will not even show a card pop up in I: unless it's the 4GB.
Already uninstalled generic drivers. Restart, then install new drivers from website.
Importing photos from the 5DII directly works fine.
Finally: Internal Card Reader is a vantec.
Please, help. I want to stab my eye out with a rusty stick if this keeps up.
