The Windows Master Boot Record (MBR) partition structure supports a total of only four (4) partitions per Hard Disk Drive / Solid State Drive, they can be either 4...

It would be easier. But how do you change a tire on a car that is going at 60 MpH on the highway.

I will write a program to be used with a microcontroller linked with car so that while driving I can give command to change the tire!..

...Anyway, the program will first stop the car, change teh tire and again restart the car!! That's so simple! :P

Just kidding

How to use unallocated hard drive space?

Got a new HP EliteBook 8560p and checking through Disk Management I see there's 167GB of unallocated disk space but I already have 4 partitions so it won't let me make another.

Here's my current disk configuration:

Partition / Extended : Logical Drives-hd-config.jpg

I did method 2 mentioned on the first page and changed the Window7 C:\ drive partition from Primary to Logial but I don't see how shrinking C:\ drive will allow me to then make use of the 167GB of unallocated space?

Sorry if I'm just being dumb, please advise on the best way to now make use the unallocated space.

Thanks.

Hello Jreedar!

I guess you don't need to shrink C: if you are just concerned about the unallocated 167 GB space. As you have already made C: logical, you can now make more than 4 partitions with new partions being logical...so now simply make one/more partition in that 167 GB space.
Right button clicking in the mouse on that unallocated space will give you option to make new partition.

Does it work?

Thanks for the reply, when I right click on the 167 GB unallocated area and select 'New Simple Volume' and take all the defaults:

When I click finish I get this error:

SUCCESS!!

OK so I decided to install and use EASEUS Partition Master 9.1.0 Home Edition which was free, and used it to change my D:\ HP_RECOVERY partition from Primary to Logical, applied the change and rebooted. After that it then allowed me to access through the normal windows 7 Disk Management utility the unallocated 167GB area and then create a new partition(G:\) and format it! So this is exactly what I was wanting!

Hope this helps someone else with the same issue.

Here's what my new disk layout looks like now with 5 partitions, a new G:\ drive made up of the previously unallocated 167 GB:

That was a smart move. Disk Management was iffy before because you unallocated space was a primary unallocated space (dark blue). It should not make any difference, but Disk Management apparently treats it differently.

Thanks, I was surprised and relieved when it worked, not that difficult you just have to know the right steps. Great forum! Thanks for getting me going!

Diskpart-any chance of scripting the commands?

I hope someone here can help or point us in the right direction.

We have Windows 7 Pro client on an AD domain [Server 2008 R2]. We have a large amount of computers we need to extend Volume 2 from 20 GB to the end of the partition [the rest is unallocated].

Manually typing in the commands works flawlessly, but would require logging into each one. Is there a way to script all the commands in a batch or vbs or a group policy?

*update: diskpart /s scriptname.txt

where scriptname is the name of the text file that contains your script.

using this works as a script if elevated:
select volume 2
extend
exit
