Rab released new version of his tool to check/verify your Xbox 360 NAND dumps and potentially even repair them if you have at least 3 'bad' dumps.

What's new/fixed:
* reduce block size for 256/512mb nands (to 0x4000 + ecc) based on user feedback (nandpro uses small block numbering so our output didn't match up with nandpro)
* make gui more responsive when operating on large nands
