Problem write Lexar 32GB 1000x

[juniorsouza]

purchase compact flash lexar 32GB 1000x on ebay but is shooting only 44 mbs RAW 1920x1080 on 5dMark III
arrived sealed original packaging.

I have another card lexar and writes perfectly 81mbs/ 90mbs.

What is the problem with this card rec only 44mbs?

It's likely a fake. Have you tried formatting?

I have 2 Lexar 1000x cards (32GB , 64GB), i know this sound kind or funny,
But sometimes  you need to break in the card. i had the same problem with my 64GB Lexar 1000x card.
I installed ML though the EOScard.exe,(i have a 5D2) then recorded small frame size eg. 1728x786 until i can full the card.
then format in camera, do this 3 or 4 times and increase the frames size each time,
But there again i have a 5D Mark 2 so this my not work for you.
