Hi,
      Thanks for the reply.
The problem is that I don't have any medium(disk) for such large images. I'm
using Linux on an Intel PC and hfsutils since I can also specify a path to a
directory. Upto 650MB I was using a normal CD.
Manual mounting gives me the error 'not a block device' if I specify the
path to the image.

I also have no clue as to how I could write my image to a hard-disk perhaps
starting at physical block 0. Maybe after that a manual mount would be
possible.(?) But I guess that would probably be too tedious.

Any other tips as to what I could possibly do ? Is there some application on
the Mac which would allow me to mount the image-file as a volume ? ( maybe
if I send it across from my PC to the Mac per FTP ) - I presume the Mac
would see my file then as a regular file and not as an image of a volume
right ?

-Nandini
