windows 7 limitation on shrinking

May 13, 2011 at 08:19:27
Specs: Windows 7
Is there a limit that you can shrink C drive? I have 500GB and Have created 1 partition with 250 and I want to create the C drive to be 100GB not 250GB. But it does not let me shrink it.

you cant shrink the C: partition as it has already been created with the Operating system on it.

They best way to do this it fully format the Hard Drive so that there are not partitions and then create one partition that is 100GB(C:) and then create either another 1 that is the rest of the space or two that are 180GB or 200GB depends on what you have left as you never get the full 500GB

Wrong answer from daniel.marriott

You can shrink the partition, where the operating system is installed to.
Most of the free downloadable Linux Live CDs do allow to shrink partitions.

Yes for sure. On Windows 7 partitions.
I've done it by myself one week ago.

It works.
But as always, you need to know, what you're doing, on playing around with partitions.

And the most important, you should have a good backup, if making any mistake !!!

To elaborate on the above. Window 7 repartitioning tools are not as robust as their third party equivalents but may be safer to use in the long run.

I have seen many user posts here that used a third party tool and FUBARed their drive. There are rules about adjacent partitions and such that should be followed.

Considering what you just stated in #7 above do you think you should be giving advice about partitioning? I suggest you ease into giving advice to areas that you are familiar with.

This forum can be a great way for you to expand your practical knowledge. There are many industry pros that frequent this board and i would guess at least part of the reason they do so is to sharpen and expand their skill set.

Following threads here, with or without participating can accomplish that goal.

Windows 7 Disk Manager can shrink the system volume but it does have some limitations. If this does not work you could try to defrag the volume first. If the shrink still fails you will likely need to use a third party tool.

Only Windows 7 is thought to be the safe way to shrink a root partition (by MS). I agree that other companies and open source can also modify partitions.

In most cases you have some un-movable file that is preventing the partition from being shrunk anymore. It may be a special file or files in use or other reasons that lock that area. Or simply not enough free space.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

I have found that the following helps if you want to shrink C to a much smaller volume (doesn't always give you enough, but usually more).
1- Disk clean up
2- Disk defrag
3- Back up
4- Turn off paging file (virtual memory)
5- Turn off System restore
6- Defrag again
7- Resize Partition
8- Turn on paging file and System Restore again
I hope that this helps.

You have to be a little bit crazy to keep you from going insane.
