I have a WD 500GB hard disk which has more than 200GB free. I wanted to shrink drive C which has a capacity of 150GB and 85GB free to create a new partition. Nevertheless, Windows 7 Disk Management only allowed me to reduce a few GBs while I want to shrink 40GB. It just says there is no enough space available on the disk(s) to complete this operation. Why Windows 7 Disk Management can’t reduce partition size even if the very drive has a lot of free space? How could I get this to work?
After reading the question, we know the author was planned to cut 40 GB out of a partition of which 85 GB free space is available. When seeing such request, the first though we have is that this is easy to do in Disk Management. However, the author failed because Disk Management said there is no enough space available on the disk. That’s seems strange.
Why the author can’t shrink more space Windows 7?
In fact, this is caused by immovable files occupying the space you want to shrink. Such immovable files can be pagefile, hibernation file, MFT backup, or other files. If the partition we want to shrink contains these files, it is possible that we can’t reduce partition size in Windows 7 to our expected value.
In this case, an useful solution is to delete or move them to another place in advance. Nevertheless, it is not easy for common users to find these files, let alone to delete or remove them. Considering this situation, we recommend to use free partition manager to help us. Among many good and bad software, MiniTool Partition Wizard is highly recommended.
