Windows 7: Hard Drive Partition Merging

Hard Drive Partition Merging

Hi, this is my first post, so bear with me...

I have a 300 GB hard drive on my computer. 250 GB was allocated, when I first bought it, to a recovery partition but I made that a backup space. Now, I have XP on the 20 GB and Windows 7 x86 on the 50 GB partition.

I've started to run out of space (10 GB left) and was wondering if I could merge or re-size the two partitions while preserving the data on both.

The 250 GB has 150 GB left and the 50 GB has 10 GB left.

I boot from the 50 GB partition, and want to re-size the 205 GB one. Is this possible? Or will I have to wipe both and start from scratch?

Thanks!

Yes, it's possible and you don't have to start over.

As I understand you want to shrink the 250GB partition some--let's say XGB to have something to talk about--and then allocate that to the Windows 7 50GB partition. I assume you're booting from Windows 7.

First, make an image of the entire drive. If you don't have something to do this you can use Windows 7's backup but it might be sloooooowwww. Otherwise use clonezilla from a CD; it's free but a little cryptic, google for a tutorial. But do make that image backup.

You might be able to do this right from Windows.

Go to Start->Control Panel->Admin Tools; then Computer Management
then Storage->Disk Management (left sidebar menu).

Right click on your 250GB partition and select Shrink Volume.

Then you should be able to type your X GB you want to shrink in the text input window. Assuming you can, go ahead and shrink it.

Now here's where I have to guess some, since I don't want to go ahead and do this on my machine. Either during the shrink operation, or as a separate operation, allocated the freed space to your 50GB Windows 7 partition. If you can't post again and we'll try some free partition managers which will let you do it.

So I won't lose any data on either partition?
That's what I was worried about...

No data loss. But! Please make an image of the entire drive and store on an external drive just in case. I always do this before partition changes.

merging the hdd partitions in windows 7

well in lots of forums i have checked and could not find a proper answer. there are 2 cases, I will explain the both;

1. If you have installed windows 7, installed and using all your favorite programs and now you want to merge the recovery partition with the system partition and want to keep your system and settings without any change. Then follow steps;

a. get your system hdd partition (usually it is c completely copied to an external drive. (I used norton ghost 5.0, do not forget checking the copy options, read help section very well, see my notes at the bottom), also make a recovery cd (not windows recovery cd, norton ghost recovery disc or your own program's) resume reading and applying following instructions (go to 2, then b),

2. if you are clean installing windows 7,
when you insert windows 7 installation cd, at a stage it will ask you which part of hdd you want to install os, click advanced, you will see the partitions delete them make then unallocated, then choose the larger one and choose format. format will ask you the size which you want to format, choose the max size (i.e for a 150 gb total hdd, write 150 000 mb). Formating will automatically keep a system partition (around 200 mb) and the rest will be your c: drive... according to the setup instructions complete the rest, you are done.

the ones should go on following steps who wants to merge hdd partition after windows 7 installation,

b. okey after win 7 installation cd you have a fresh win 7 installed in your system with a complete c: drive. Now put the norton recovery disc into the cd tray (or your own copying program's recovery cd) and resart. Recovery will offer you some options, choose recover my computer, show your recovery point in the external drive (actually it is in a folder somewhere between your system hdd' copy folders). Your hdd will be copied back to your merged drive. It is done!

p.s. 1. while my experience with norton ghost 5.0 I paid attention to the copying drive-to-drive options as follow;
*check source for file system errors (check)
*check destination for file system errors (check)
*set drive active (for booting os) (check)
*disable smart sector copying (check)
*copy mbr (check)
do not forget to check these options while you copying hdd to external hdd and vice versa...
2. If your computer does not start after all and/or asks for win 7 installation cd, do it, choose repair (99% your startup section needs to be changed because of hdd change) and everything should be perfect after repair... good luck

300 GB total HDD
298 GB I actually use
100 MB System Reserve
so 298.09 GB I keep using
if you are asking the rest please see HDD documents, where is BIOS, Start Up, Partition and hardware I/O, HDD's own firmware etc. written. When you buy a HDD whatever it says like 500 GB, 1 TB etc. you can not see the whole quantity as "usable"... Because some software is installed to run HDD itself and adapt it to your system. You should know that
Anyway, before I did merging, Sony was reserved (if I am not misremember) something around 20 GB...

Sorry,i read wrong,i thought it was a 350GB

But thats not whats taking the space your on about,the manufactor uses 1000MB = 1GB where as the computer counts it as 1024MB=1GB
