i have my main OS partitioned off at 80gig. i have a Data drive that is 100gig and a 57gig. The 80 is to be expanded to the 57gig to make the OS partition larger. When i right click on the drive Comp. Manager the extended is greyed out. i have removed the 57 partition as unformated and reformatted it and the same thing occurs. now i saw something about the dynamic disk. is this something i should do and will it delete any data if i do convert it over? or should i even convert it all?
