Salut ;o)
I just received a A-DATA "speedy" 16 GB CF and it works well on my IHP 120 (bootloader 5, latest build). I made test (24 h random mp3 play, 2 hours recording .waw, navigating in menu) and NO FREEZES (I had many ones using other cards).
The same card is not working with my IHP 340
I made test with a TRANSCEND 16 GB (133X), the card was never recognised by the IHP120 (ata error).
