I am familiar with the workings of FDISK so I need not to have explained to me the inner workings of FDISK. What I would like to know is if there is anyway by using fdisk or a specific utility one can change a primary partition to an extended partition containing a logical dos drive without haveing to do it the traditional way of backing up the data and and repartitioning the drive and then restoring from backup. The reason I want to do this is to change my drive letters.

Also, I have never used partition magic. Is this possible with PM and if so how?

The ultimate goal is that I need a way to change my drive letter assignments.

Thanks in advance to any who answer. Answers of "no, there is no way that I know of to do this" are also acceptable!
