CF Card no longer works

[khillstrom]

Hi all,

Here is my situation.  I have a 5dMII and I recently put ML on it.  I usually shoot with a Delkin Devices 64Gb UDMA7 card.  However, I used a much smaller 1Gb card for the initial install of ML.  Install worked great, no issues.  I then followed the directions and put ML on my 64Gb card and tried to use it.  However my camera does not read the card.  It asked me to format the card... when I try that, it says "Cannot format card".

This CF card works fine in my computer.  Ive tried formatting it in several different formats... different computers... ect... and nothing works.

I then reverted my camera back to the 2.1.2 firmware and still it will not read/format this card.

anyone have any ideas?

Wipe the card using a cardreader, format it there (FAT32) and try to write to it. Success?
