As I stated in an earlier thread, I'm getting a new eMachine with a 40 GB HD. I'm having my older Maxtor 40GB drive installed as my secondary/digital editing storage. The Maxtor is already partitioned into 5 8GB drives. I'm considering partitioning my new computer's primary drive into 4 10GB drives. A friend of mine who's pretty computer savy says it's not necessary for systems with XP, since it allows you to set up individual space for each user. Is there an advantage to partitioning versus not partitioning on my primary drive?
