problem with SD Card

[Nicolas LAURANCE]

Hi all,

I'm a newcomer to this list

I just received a new sd card

a SanDisk SDSDQ-8192-E11M, shown as supported in 
http://wiki.openmoko.org/wiki/Supported_microSD_cards


following these instructions : 
http://wiki.openmoko.org/wiki/Booting_from_SD#Partioning_the_SD_card
I managed to fdisk it
create both partitions
format both partitions
and mount them
I then rebooted the FR and it crashed in kernel panic

I rebooted on the flash

but now :
root at om-gta02:~# fdisk /dev/mmcblk0
fdisk: cannot read from /dev/mmcblk0

dmesg shows :

any help to put my hand back on the card is greatly appreciated
I don't mind to loose every data on it

thanks
Nicolas
