<p>Techniques for restoring index pages stored in non-volatile memory are disclosed where the index pages map logical sectors into physical pages. Additional data structures in volatile and non-volatile memory can be used by the techniques for restoring index pages. In some implementations, a lookup table associated with data blocks in non-volatile memory can be used to provide information regarding the mapping of logical sectors into physical pages. In some implementations, a lookup table associated with data blocks and a range of logical sectors and/or index pages can be used.</p>
