I have installed udisks and udisks2. I can follow these steps: http://archlinuxarm.org/platforms/armv6/raspberry-pi to the step 4. where the following command: mkfs.ext4 /dev/sdX2 can't be completed successfully, because after I run it, I can't mount the new second partition formatted to have ext4 type filesystem. I tried these steps by using Gparted too, but at this step Gparted can't read partitions from the during read on /dev/mmcblk0 Gparted gives the error message: I/O error during read on /dev/mmcblk0 What can I do to solve this problem? -- Regards from Pal
