  1. I could shrink the volume to only half of its size. Say initially a 60GB dark disk can be shrunk only to 30 and 30. I think this applies mainly to primary partition.

  2. Great tutorial. Can you repartition drives in Vista or do it have to be unallocated space? That’s one thing I hated in Vista, you could never change the size of a parttion.

  3. Nirmal, You can shrink the volume to whatever size that is available.Not necessarily would automatically calculate the available shrink space after taking into account the space currently used by your data, on such drive.This available space may further be restricted by snaphots and pagefiles enabled on that drive.

  4. Aseem, Thanks and yes you can and that is what this article is about…you have to shrink an existing drive to create unallocated space and then use this space to create the new partition.

    You can shrink, extend, create, and format partitions.What do you mean when you say that you could never change the size of a partition in vista?

  5. Infact in vista, you can resize the partition (extend or shrink the volume size), without loosing data and without the need for a third party tool like Partition Magic.

    But backing up your data, in the drive that you want to partition, is always a good practice, before you actually carry out the partition.

  6. When I tried to shrink my C drive, the primary partition and Vista installation drive it didnt allow me to reduce the size of C below its half value.
    Initially it was 80GB and when I shrunk it C could be reduced only to 40GB and not less than that. I think you got my point.
