everytime I try it, with different excel sheets and trying to tweek the code

The error I get is:

[PATCH 00/12] Multidisk support
Hello,
the following patches should get multidisk access working.

the other accepted syntax is using MBR's 32 bits disk signature so for example:
(mbr:0x12345678,2)/foo/bar
