Formatting NXT compact flash cards

[stayouttadabunker]

Compact flash cards are basically Flash memory with an IDE interface or PCMCIA, depending on which pins are shorted on the card (yes, you read that right).  It supports CHS logical block addressing and some CF cards even have wear leveling for the NANDS.  So as far as the host interface for the CF card is concerned, it's nothing more than a hard drive with (Cylinder Heads and Sector scheme).  This is the drive geometry that must match in order to pass validation as the hash algorythm takes this into account when comparing the Hash in the CF program to the calculated one as the validating routines calculates the hash.

Awessome!
With this in mind...
How does one know whether or not their CF card is bogus and miss-matches the hash algorithm?
It simply doesn't work and an error pops up on the LCD screen?
Besides spending an arm and a leg - are there any ways around this?

Unfortunately, there's no way to know until you can test the card.  The giveaway is to look at the capacity of the card, they must match to the byte or they will not work.  I know that simple-tech oem'ed some sandisk cards, so sometimes you will see these cards as WMS original cards, but they are not as common as the typical industrial type cards that are commonly seen.
