How can I merge and split partitions to change their sizes without formatting?

My HDD is 320GB. I did partition it by using disk mgmt, so have C and D both, with 139 & 129, respectively.

I needed a third partition with equal capacity, but couldn’t do it using disk mgmt. So I used Partition Magic and split C drive to make a new partition of 40GB.

Now I want to split the 40 GB from D drive and merge it with E, to make C 100GB, D 100GB, and E about 80 GB without formatting because I don’t have laptop driver CD. It’s an Aspire D270. What should I do?

    first of all, backup your data. and then you may know partition wizard. the newest version can split partitions in one simple step. but if you want to merge partitions, you may have to pay some money. if you dont want to pay, use windows partition manager.

    use a free software called Mini Tools partition wizard home its free... you can do search for it on google ... it has way many features you can use later in case you ever need shrik or extend your partitions size ... if you have only one drive windows installed in it you can do it from desktop right click on computer select manage it will show you Computer management window from left panel select Disk Management there you can right click on your only one disk and chose shrink volume ONLY so you can chose later free space which you got from shrinking your ONLY partition

    I normally use a Linux Live CD. Boot it up and use the disk manager software inside.

    Use EASEUS PARTITION MASTER. With it you won't need to format or delete anything. Just by moving a Slider you can adjust the volume of your new partition.
    Whatmore, its free for home users.
    I divided my 500GB HDD into 3 partitions.

    Use EASEUS PARTITION MASTER.
    U don't need to format any existing partition and by just moving a slider create a new partition which works.
    I used it to divide my 500GB hard disk into 3 partition.
    Whatmore the software is absolutely free for home use. :)

    You need to first shrink disk D to release the 40 GB.
    Moreover, the unallocated space must be left before to the D drive (after the drive E) and not at the end of the disk. (with the built-in DdiskMgmt can not handle it, it is better to use some of the recommended users)
    Second, expand drive E on all the free 40GB.
    I did that all operations with the partitions, with the aid of paid Paragon Hard Disk Manager.
    For You I can recommend PartitionGuru free - the most advanced of the free tools.

    without looking at files and assuming space-wise this won't cause any problems
    boot up Gparted Live (you should be able to use a flash drive) (if Ubuntu is installed boot into that and install/open Gparted)
    Then you have to shrink C & D then move D over and expand The third partition needs to be moved and expanded
    You'll be warned about potential data loss but it's never happened to me (be sure you're doing it right) then it'll take time and you can reboot back to windows
    done

    the best way is to delete all the partitions, and re partition the entire disk. what you are going to do is, get 40GB from C nd trying to merge it with the E partition. ( that's what I understood from your description ) logically this is not possible.

    another thing you can do is, merge the 40GB to the D drive. and then take out the excess 40GB from D to E. that'll work.. bt From C to E is not going to work.. ( with the experience i have )

    or else, try a formatting. it'll save your precious time. if you are only worried about the drivers, just get them from here. if the model is not Acer Aspire on D270, please leave a comment and I'll find it for you. :)

    You need to merge the partitions first then re-partition your HDD as per you requirement through Disk management.

      that would require formatting

    An alternative to Partition Magic is Paragon's Partition Manager. The free version will allow you to create, move, resize, and delete partitions. The home version (currently $10 on their site.) includes the ability to split, merge, and undelete partitions (among others). More details available here.

    If you don't encounter the problems Mike described, you should be able to just use Partition Magic again.

    I believe you are facing the limitation of primary partitions within the Master Boot Record.

    The MBR does not support more than 4 primary partitions. Since you are using an "out of the box" notebook with Windows 7 you may have hit that limit:
    1 System-Reserved
    2 Windows (C)
    3 data partition (D)
    4 some hidden manufacturer partition containing recovery and/or other tools

    Assuming that is correct you simply can't create another partition on your drive.

    You could try converting the data partition (D) into an extended one which would then act as a container for multiple other partitions. However, I'm not sure you can allocate the current free space to this extended partition.

    I think the best way to go about is to make the data partition as big as possible (including the 40GB from C), then convert it into an extended partition.
    Once that is done you should be able to resize it and create another partition wihin the now 100GB free space.

      D usually is recovery
      though you can put whatever you want on there

      I agree. This software works. A required reboot, which is no big deal, and your drives and partitions are ready

      it is always recommended to make a back up of your files before performing any disk partition

    move your files to the bigger one, delete the files from the origin partition and then merge the two partitions.
