I have a 6.8GB ADFS hard drive image I want to use with VRPC Adjust. I had a working 250MB IDE image in VRPC so I tweaked Model.cfg to point to the larger file and use the right geometry:


I can access the file quite happily in Windows (it's on a network share as I don't have enough space to store it locally) - Windows correctly sees the size and can load the file into a text editor.

However VRPC reports this when I try to use it:


Does VRPC's disc image support cope with images larger than 2GB?

You have no said how the drive image was created - so the following will assume that it is a direct dump of a drive from a "real" RiscPC.
You will need the information that was used to format the physical drive as the "shape" command will need to correctly match this (number of cylinders etc) or the drive image won't work as the data won't make sense. In addition if the shape didn't match the drive formating parameters correctly you run the very real risk of data corruption (and that's just from trying to "mount" it under RISC OS).
