This disclosure describes techniques to store a partition table that represents an unreliable storage device such as NAND flash external to the storage device. The partition table is stored in a storage device with greater reliability, such as NOR flash. The reliable and unreliable storage devices are mounted on the same circuit board. The techniques enable simple firmware to be used to access the storage device. The technique can be utilized in embedded systems and other computing devices to provide reliable storage at a relatively low cost.
