If install scripts such as" nand-sata-install" are not working, with the error message about partition size, cd into /mnt and delete the unwanted script remnants with the command sudo rm -r -f (unwanted file)
**example:** "sudo rm -r -f nand-sata-install.ctNNK4"
Each time that you remove the install scripts from /mnt , you also have to unmount /dev/md0 (sudo umount /dev/md0) otherwise it will give you an error saying nand-sata-install.xxxxxx is in use and can't be deleted while attempting to delete the next. When you are done, make sure there is nothing other than md0 (if you're running on an arrray) in /mnt and then unmount /dev/md0 for the last time before running the nand-sata-install script.
the script will now work.
Also, I'm guessing you might have to do the same with /dev/sdx if you are using an mdadm array.
