Swizzy has released a new app dedicated to JTAG/RGH XBOX 360 consoles. This one will assure you have a valid NAND dump.

x360 NAND Dump Checker by Swizzy, allows you to check each page of your Xbox 360 NAND dump for ECC errors...


It does this by calculating the ECC data and comparing it to the one stored in spare. It'll tell you if it finds what it believes to be a badblock (if there is no ECC data stored in spare it'll assume it's a badblock).

Includes GUI and command line version of the tool along with source code.
Requirements: Microsoft .NET Framework 2.0 or later.
Information:


Verbosity level 0 = Normal, default level, only prints badblock info for each block and most errors/warnings
Verbosity level 1 = Medium, prints all bad pages and all errors/warnings
Verbosity level 2 = Full, prints ECC information for each page bad, and page status…
Verbosity level 3 = Debug, prints information of each page and more…
That's right, there are two versions a CLI (Command Line Interface) and a GUI one.
