Which is the filesystem from booting? Have you tried only with this sd card? Have you tried with others filesystems? 2 Months a go I was with the same problem, finally It's was the problem with sd card, chinese sd card and than I had bought sandisk sd card. But from your bootscreen I see the sandisk card. Maybe you must try to format low level and than will make the new partitions. Sometimes the sd cards from boot are corrupts, It's strange but true story :) Try to format in zero fill --> su unmount /dev/sd0a sudo dd if=/dev/zero of=/dev/sd0a bs=1m count=1 and with fdisk can you make the new partition table.
