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?
