I have had my computer for a while and i have 50 gb's on one partition and 100 gb's on the other, and i would like to combine them into one. How do i reformat it to where it is only one hard drive? Also will i lose anything on either partition if i do this?

If I understand you correctly, I think your best option is to do the following:

Assumption:
The disk is a Windows XP system disk, with the OS in partition 1, and partition 2 contains ONLY regular data files and folders...no applications*.

Procedure

1) BACKUP your disk(s)

2) backup or move* the files on the second partition to another disk or the first partition...recommend storing them under a unique folder-name.

3) use a partition management program such as freeware PartitionLogic, or Windows built-in utility "Computer Management" to 'delete' the unwanted 2nd partition.
e.g. Using Windows "Computer Management"
Start>>run>>compmgmt.msc>>DiskManagement
Right click on the unwanted 2nd logical drive (partition)
and select "Delete Logical Drive". This will free up that space on the disk so that later it can be "added" to the 1st partition.

4) you then use a partition manager utility such as freeware PartitionLogic (ver0.69 or above) to increase the size of the system ntfs partition while leaving fully intact all the OS and other files that are currently in the 1st partition.

http://partitionlogic.org.uk/about/index.html
(note: only version 0.69 and above can re-size Win-XP NTFS boot partition. Version 0.69 is the current version as far as I know. PartitionLogic does not support some SATA hard disks)
Download the PartitionLogic .iso image. Burn it to a CD. Boot the PartitionLogic CD and follow the menus to extend the 1st disk partition into the unallocated space on the disk.


*IMPORTANT: if you have applications setup in the 2nd partition, or have shortcuts to files/folder in the 2nd partition, all those will likely be rendered inoperative after the change. Some people also set application output to a specific drive or partition. For example, you might have setup email to store all the files in your second partition. By effectively deleting the partition, the email program won't know where to go for old emails or where to store new ones.

Sometimes it's a simple matter of setting shortcuts and such, but at other times complex registry changes are needed when you try to move applications. There are a few utilities that supposedly make this easier.


Example of Re-sizing Procedure Using PartitionLogic
Note: system disk is assumed designated "Disk0"

Boot the PartitionLogic CD
Select "Run" (do NOT select "Install")
Select Administration>DiskManager>Disk0>Resize>Filesystem&Partition
(enter desired new size of partition)
Close the open windows
Remove the PL CD
Exit/Reboot

Well, since the OP used the term 'reformat' to 1 partition in his post, the easiest way would be to use hr Windows boot disk.


Boot from the WIndows CD, and follow the on screen prompts as if you were re-installing Windows.

You will reach a screen where it will ask which drive to install Windows on - your 2 partitions should be showing.

You can select each one, and preass 'd' (iirc) to delete each partition.

You will be left with one large, unpartitioned disk.

You can then type in the entire free space to create a single partition, the sizre of your disk. Windows will then proceed to format the disk.

I kind of interpreted it as just casual mis-use of the word since he later asked if he'd lose any data...it usually goes without saying that reformatting whacks your OS and data, so I thought he was looking for a less "all or nothing" procedure.

But, whatever solves the problem. As long as he backups the disks he can pretty much re-partition/re-size any way that works and then restore the data to the new partition. That's what we all try for.

Bennie,

I think pretty much everything you and EaseUS says in their tutorial has been said earlier in this almost 3 year old thread. You simply could have said
"Here's another freeware partition manager tool that can help you do this."
and then provide the link.

However, one might also point out that the freeware version of EaseUS Partition Manager is a limited version of their "Professional" Partition Master product that sells for $20 (and higher). The free version's license also seems to have substantial limitations on how one is allowed to use it.

Don't get me wrong, I like some of the tools provided by EaseUS, but people should be fully informed when there are limitations or the publisher is trying to market non-free versions as well. Sometimes the practical differences between versions are few for individual users...sometimes they are quite significant and have the potential to cause problems for the user and/or his clients.

Here's a comparison between the free "Home" edition of EaseUS "Partition Master" and their other non-free versions.

p.s. I love it when companies name their products "Master". I either think of Igor in "Young Frankenstein" or whips and leather clothing (of course never, ever both at the same time...Ha! Now get THAT image out of your brains you pervs...)

It may also be useful if you run into any SATA configurations that the Linux-based self-booting or "LiveCD" partition managers can't handle yet.


Plus, a cautionary word when using ANY partition manager...

I think something you still have to watch out for if you use TrueCrypt or similar partitions. Since the encrypted partitions can be made "invisible" to Windows (and other Operating Systems) one could accidentally totally screw them up when resizing/extending existing partitions. The partition manager might "think" that disk space is available when in fact it contains gigabytes of encrypted information. So be sure you know where your "special" partitions are located before manipulating partitions using tools like this.

Try a program called partition magic, It should do the trick. You wont have to erase and then re-format everything. But It is always a good idea to back everything up before doing something like this just in case.

i installed one partition manager tool, it can merge the two adjacent partitions and the unallocated space between them. but if you partitions are not adjacent, it may not work.
i found it from:http://www.partition-tool.com/easeus-partition-manager/merge-partition.htm

Hello,

Quick question. In your instructions you mention to click on "Delete Logical Drive". Unfortunately I have "Delete Volume". is this the same?

Thanks.

Hello Friends,

Go to: Control Panel
Admin Tools
Computer management
Disc management
On the right hand side, you will see your hard drives. Right click near the bottom, and you could see 2 partitions on the same drive. From here, you can then remove the partition, and reformat the drive in question.

Best Regards
Steven Arnold

Hi,

In my view, there is no way to combine two partitions and make it into one. The only way is to reformat, after taking a backup of data of two partitions. There are of course software’s available to do this job, but they are not reliable.

May i know the actual purpose of combining the two partitions and making it into one?
