Best way to partition Pavilion15-au123cl Notebook

HP Recommended
Pavilion15-au123cl Notebook
Microsoft Windows 10 (64-bit)

I have just purchased a Pavilion15-au123cl Notebook and would like to partition its 1TB hard drive to allow approximately 200GB in the C: partition for the OS and applications, and then use the remaining space as a separate partition for data storage.

 

As I recall with my last HP notebook (Envy M6-1125dx with 750GB Drive), I was not able to shrink the C: Partition below about 335GB so ended up not being able to allocate the full amount I would have liked to the data storage partition and would like to avoid this problem with the new notebook (I never fully understood what the hang up was on this one).

 

I would appreciate it if someone could provide guidance on how to successfully partition this new Notebook so I can maximize the space allocated to the data storage partition.

Windows disk management is just not going to let you shrink the C:\ drive to less than about 50% the capacity of the hard drive. This has not changed with Windows 10. If you want to do that (and I do not really recommend it but hey, it's your laptop) you are going to neeed to get a more powerful third party partitioning tool like Partition Commander, Paragon Partition Manager, etc.

Thanks for the quick reply, Huffer. I'm not real technical, but would be interested in knowing why you think it would be a problem shrinking the C: drive. If 200GB is too small what would be your recommendation? I wanted the OS and apps in a separate partition that can be restored without disturbing the data partition if I have a problem. That used to be a recommendation but maybe I'm behind the times now. I would like to hear your thoughts on pros & cons.

Nothing more than 200 gigs is too small, and the plan is not as secure as you hope. I would just shrink it as much as Disk Management will allow, and keep two partitons. Your separate partition scheme is better than no backup plan at all but why not use a real backup that can provide you with an exact image of the entire contents of the hard drive including apps if there is Windows corruption,  a complete failure of the hard drive or a virus? I can assure you modern malware will not have any trouble jumping over a simple partition and infecting data on your storage drive. Windows 10 has some very good backup and recovery options and all you need is an external drive or it can even be backed up to the cloud.

The limitation you're running up against has been in place since the Win7 days -- this is nothing new.  Disk Management limits how much you can shrink the C: volume because there are system files on that volume that it refuses to move.  That sets a limit on how much space you can remove from that volume.

 

An alternative that I use is this linked tool:  http://www.partitionwizard.com/free-partition-manager.html

 

That will safely allow you to shrink your C: volume to something smaller, say 80GB (which is what I use).  It will reboot to perform this operation because this can't be done while Windows is running.

 

As to performing regular system image backups, I do that every week and strongly recommend a third-party tool known as Macrium Reflect:

 

I personally prefer to use third-party Recovery solutions as they tend to be both more flexible and more reliable than any built-in solutions.

Macrium Reflect (MR) provides a FREE version that can be used to image and restore partitions or entire drives: http://www.macrium.com/reflectfree.aspx

What I recommend is the following:
1) Download and install Macrium Reflect (MR)
2) Run MR and choose the option: "Create an image of the partition(s) required to backup and restore Windows" to write a full backup to an external drive or USB stick
3) Use the option to create a boot USB stick or CD

My experience is that MR, when using the High Compression option, typically can compress the saved image file to about 50% of the USED space in the OS partition. This means if you have an 80GB OS partition, and 40GB is used, MR only needs about 20GB to store the image file.

I use this all the time and it typically takes less than 10 minutes to do the image backup and about the same time or less to do a restore.

Plus, MR has the option to Add a Recovery Boot Menu entry. This allows you then to boot into WinRE, and you can then use that to do a restore -- when you can't boot into Windows!

NOW, you have the means to restore a full working system from the external drive or USB stick in only a few minutes.


Good Luck

Thank you for your advice and it was exactly as you said...the Windows tools won't shrink the partition fully. I also found this post which describes doing the same thing with AOMEI free partitioning software.

 

https://answers.microsoft.com/en-us/windows/forum/windows_10-files/disk-partition-why-cant-hard-disk...

 

FYI: I have been running for several months with absolutely no problems using a 200+GB system partition and a 700+GB data partition which should be more than enough for my needs.
