Anyone know of a resource to fully explain the Masks used in NAND recoveries (eg 0xFFFF) when converting data by using block numbers (eg 0000).
Thanks.

It is a bit mask.

https://en.wikipedia.org/wiki/Mask_(computing)

Specifically, it utilizes the AND operation.

If you do a search there is somewhat of an explanation, in true minimalistic style, in a convo between Sergey and Jeremy. http://flash-extractor.com/forum/viewtopic.php?t=4176 Read both pages.
