To try the above solution, do not forget to run update-grub. This is the result after running the update

localadmin@backblaze:~/mnt$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.2.0-23-generic root=UUID=de87ad5f-e76f-4180-a7ce-9b29c9443b9f ro libata.force=noncq

Apparently NCQ will reduce the rate of writing so the rate of errors will be decreased.
NCQ will force the sys/block/sda$i/device/queue_depth value to drop from 31 to 1.
