defragging in winxp pro

[Chris]

hi all,

i have several partitions on two different hard drives.
when i try to defrag i can only do one partition at a
time. i mean, defrag C:, then when that is done start
defrag on F:, then when that is done start defrag on G:,
etc.
in win98 i could just start defrag and then all
partitions would be defragged sequentially. i did not
have to manually start defrag on each partition.
am i missing something in configuring the defrag in winxp
pro?

thanks,
Chris
