Cowon D2, still the audio KING

64GB SDXC card for the O2 works!
I got a Trancend 64GB SDXC card from Amazon to use in my Cowon D2 and O2 players.
When I got the card, it came formatted in the 'exFAT' format, which doesn't work on either player.
I have a card reader on my computer, and putting the card in, I tried to reformat it in Windows 7. It allows me to format in 'exFAT' or 'NTFS' both of which don't work on the D2.
So doing a web search led me to this free Windows utility that lets you format the card in 'fat32' format, which then makes the card work for both players.
Note that you cannot leave the card in your player when working with your computer to format/transfer/delete. You need a USB card reader, or a card reader that's in your computer. So to format the card, or to transfer or delete files to it, you need to take the card out of your O2/D2 and plug it into a card reader if you have Windows 7. Using that utility above to format the card to 'fat32' you can then drag-and-drop music or videos to the card.
If you get the 128GB SDXC card by Lexar (the only 128GB card I know of right now) this should apply to that card as well, but I'm just guessing.
BTW, using the D2 and O2 as flac players for all my 24-bit high definition files (converted to 16-bit flac as they don't do 24-bit, no big deal) along with a Headroom Total Bithead amp and various headphones (like the Etymotic ER-4P and Ultrasone Pro 550) for a portable, super high-quality listening session.
The D2 is still, in my opinion, Cowon's best MP3 player ever, with the O2 following a close second. Thankfully the batteries for the D2 are still available online, but I worry about my O2!
