What is your fragmentation status? Vista can shrink, but cannot move data around, so it cannot do it beyond where there is data on the partition.
That's what he meant.
Defrag first then try to shrink.
	
	Now im confused and asking. I wanted to create and extended partition on the primary. Im good with defrag. for the record do i shrink the drive c: and then partition. Im figuring thats what it is.
im asking because i have two drive's. (internal). i dont really want to use the usb external. then again i won't loose both my internal drives at the same time. then i will sync the drives.
	Windows is fussy about what it will let you do to the C: drive.
Although the option may be there to Shrink the Volume, there may be services or applications running that won't let you.
The C drive is no different than other drives. The issue is Windows not being able to move data around. That issue exists not only on C.
But the point is still about where the data is stored. If you have a data drive and there is stored some data at the end of that partition then you will not be able to shrink that either.
The OS partition is not different in that way.
still cant seem to find the problem. tried everything that i can think of.
	That was my entire pointWhen shrinking the partition, the software should move any data from the end of the partition with no problems.
But that isn't an issue. If you try to shrink a new installation (on a newly formatted partition), you can shrink it 50% (goes for all your NTFS formatted drives, because of the MFT-mirror).imagine trying to change a tire on your car while you're driving? Bad analogy yes, but the principle applies.
