Help shrinking boot volume on SSD

post #1 of 7
Thread Starter 
I installed Windows 7 Pro 64 on a 256GB Crucial C300 SSD. I've been playing around with setting up RAID arrays for other disks, so the only thing I've installed on C: so far, aside from the OS, are drivers and disk performance measurement apps.

Now I would like to repartition the C: drive so that the OS has its own partition, to make it easier/faster to make disk images of the OS for backups and testing various configurations down the road.

With this being an SSD, is it possible to shrink the current C: and then repartition the drive without needing to reinstall and re-activate Windows?
And what software do you recommend? (can be free or payware)

I've seen lots of discussions about shrinking C: on an HDD for moving to an SSD, but not so much on shrinking C: specifically on an SSD.
After seeing a suggestion for using EASEUS, I've looked at the instructions for managing disk partitions on EASEUS Partition Manager's website, but the examples they give they talk about extending C:, or about shrinking non-C: drives/volumes, rather than shrinking C:; they also don't talk specifically about shrinking volumes on SSDs.


The other question is, if it is possible to do the above, about what is the minimum size that Windows 7 Pro 64 needs to function well?

First, get Paragon Alignment tool, you'll be needing it eventually if you mess around partitioning SSDs.

Any luck?

I'm sorry for not giving much of a guide to help you out. I had to leave my house for something.

You don't need Paragon Alignment tool as partition wizard home has this function built in.

All you will have to do is right click on the partition of the disk you want and select move/resize. Then click apply in the top corner.

Then to make sure that it is aligned right click on all the partitions on the SSD and select align. Then apply like before and your good to go.

Thanks for asking, Andrew. I haven't tried anything yet since this could end up being an irreversible disaster. I've been reading dozens of forum posts and various products' user guides and support discussions to see whether anybody has discussed doing this successfully before. I haven't yet found someone describing personal success with the exact scenario I am describing with any partition management program.

I have resized my boot partition on my solid state drive several times before with success. If you want you could create a system image which is an image backup. This will backup everything as it is when you do it.

What exactly are you trying to do again?

I used GParted. Seems to have worked, so far anyway.
Didn't need to run any repair function. No BSODs.

I shrank the C: drive from 190GB to 70GB.
(To be on the safe side, I made a backup first. Then I turned off the paging file, and I had never started System Restore since it was a new installation. I ran CCleaner and Disk Cleanup. Then I ran GParted.)


I looked at various other programs before that, such as Paragon Partition Manager, O&O Partition Manager, and EaseUS Partition Master. I suppose any of them may have worked, but I was not reassured by seeing that the information in their user guides in several cases didn't seem to have been updated since Vista. eek.gif Sure, it may be that the software works as just as effectively or even better in Win 7 as in Vista, but I would much rather they had told me so in the instructions rather than having to just accept it as a matter of faith!

In EaseUS, I found a page that says
Quote:
General speaking, when you click "Apply" button to commit the operation on Partition Assistant. The operation will be completed under Windows Mode....

However, some operation could not be completed under the Windows Mode, such as "Shrink system partition", "Clone System Partition" or some live applications(include page file) are running on the partition which you want to resize. The target partition could not be locked; therefore the operation will be completed under the boot mode (Partition Assistant PreOS Mode).

Manual start Partition Assistant PreOS mode:

In order to make process running under boot mode you should holding down "shift" when you click "Apply" on the toolbar, and then it will commit the operation under PreOS mode.

The problem with ^ that is that they didn't mention ANYTHING about PreOS mode on the main page that describes how to resize a partition. Someone using the product could easily have missed this other information and possibly ended up needing to run PreOS mode without knowing anything about PresOS mode.
It just doesn't instill much confidence.
