Hi Joel,

Perhaps it has something to do with MSDOS partition tables and logical 
partitions?

When a logical partition is deleted, it affects the partition numbers of 
each logical partition that follow in the chain.

For example, an extended partition contains four logical partitions A, 
B, C, and D. These logical partitions are accessed by the operating 
system as follows:

    *  Partition A as /dev/sda5.
    *  Partition B as /dev/sda6.
    *  Partition C as /dev/sda7.
    *  Partition D as /dev/sda8.

If partition B is deleted, then the remaining logical partitions will be 
accessed by the operating system as follows:

    *  Partition A as /dev/sda5.
    *  Partition C as /dev/sda6. Note the change in device name.
    *  Partition D as /dev/sda7. Note the change in device name.

This is just a guess since I haven't looked into the renumber partition 
function.  :-)
