Sandisk 16GB SDHC not mountable

I partitioned my 16GB SDHC (class 2) card, so I had a 512MB ext3 primary partition as /dev/mmcblk0p1, but Qi would not boot from it.
So I booted my NAND system (older SHR-U, 1.6.29 kernel) which shows me correct partition with fdisk -l but would not mount it.
I recreated the filesystem with mkfs.ext3 on freerunner but it still would not mount it. fsck could not even check the fs:
e2fsck -f -C0 /dev/mmcblk0p1
e2fsck 1.41.9 (22-Aug-2009)
e2fsck: Superblock invalid, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/mmcblk0p1
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
Trying the fsck suggestion to use an alternate superblock did not help either.
I then created a partition and filesystem over the whole disk, but same result. No chance to even check the filesystem.
I also tried to switch back from Qi with glamo 242 to the old one - still no success.
In my 2 card readers the card does work though.
Does anyone of you have any ideas?
