Post subject:  Need help calculating WD module checksum

I have a WD3200BEKT with an inaccessable loader.
I found the module by reading track -135.
According to module 02, the size is 511, so I extracted 261,632 bytes to 11.rpm starting with the ROYL header.

The problem is when I send the ldr to the drive, I get a OVL CHECKSUM error

How do you calculate the checksum ?
Does anyone have a program (or source code) to calc the checksum ?

I previously uploaded a free checksum calculator that was written by Pete Disdale:
download/file.php?id=4921

The checksum is a 32-bit little-endian sum over the module's contents. It should be 0.
