Re: [coLinux-users] Re: Mounting raw partitions - Available debugging steps? [SOLVEDish]

I don't know details, and I also just go by trial and error, but it has
to do with Windows having the notion of "logical" and "physical"
partitions numbers.

For example, primary partitions are always first than extended
partitions. If you had a second hard-disk, the first primary partition
on the second hard-disk will have a lower letter than the extended
partitions on the first hard-disk.

It seems colinux paths use the logical partitions numbers, that can map
to different physical partitions numbers.

Eventually, we can make colinux to use physical partition numbers. It's
just a matter of knowing how (eventually we can "talk" to the disk
manager to get this info, but probably there is some API already)...

Well, my "heads" are spinning now, so good luck ;)
