DOS and Linux will interpret the contents differently.

This is not a problem unless you use very old DOS. You're much more likely to cause more harm than good trying to correct this, especially in the extended partition. And for no good reason!

man sfdisk shows this hopefully useful option:

Code:
       -L or --Linux
              Do not complain about things irrelevant for Linux.
