I just bought a new 8Gb SDHC card, but I am not able to create partitions on it. Not when I am using GParted, nor when I am using mkfs.

When I insert the SD card the following shows up in dmesg:

...

[ 8488.662181] mmc0: card lacks mandatory switch function, performance might suffer.

[ 8488.839524] mmc0: new SDHC card at address b368

[ 8488.839870] mmcblk0: mmc0:b368 SMI-S 7.54 GiB 

[ 8488.842163]  mmcblk0: unknown partition table

But when I try to use dd to write an .img file to the SD card a lot of I/O errors show up:

...

[ 8639.446903] mmcblk0: error -123 sending status command, aborting

[ 8639.446905] end_request: I/O error, dev mmcblk0, sector 460672

[ 8639.446910] end_request: I/O error, dev mmcblk0, sector 460680

[ 8639.446915] end_request: I/O error, dev mmcblk0, sector 460688

...

When I try to create a partition table in GParted the following error also shows up:

...

[ 8840.084006] mmc0: Timeout waiting for hardware interrupt.

[ 8840.084252] mmcblk0: error -110 sending stop command, original cmd response 0x900, card status 0xe00

Does anyone have a clue on what to do to make this work?
