Changing partition size

Is there a way, actually a reliable way, to change the sizes of the partitions on my internal hard drive without reformatting? I am using OS X 10.5.6 with an Intel Core 2 Duo iMac.

OK. I tried that. My problem is that I have three partitons. Partition One has OS X and Apple applications. Partition Two has my Users folder. Partition Three has non Apple applications. I made the middle one smaller thinking that I could increase the size of the third. Well apparently you can't do that (the third partiton wasn't able to be made larger), so I put the middle one back to the way it was.
The bottom line is that I bought a new external HD and I moved my User folder to that drive, leaving me with an 80 GB windfall on my internal drive. Now I'm thinking of just leaving things the way they are, but moving my applications to the now larger partition (where my Users folder was). Would that be a problem as far as running the applications (these are all non Apple apps)? Moving all these apps is a lot easier that having to reinstall them.

Can I change partition size of external HD without losing Data

I have an external HD that I use one partition for backup and use another partition for Time Machine. I need to change the sizes, need more on my backup. Can I change partition size of external HD without losing Data? I just changed from a Powermac G4 using Leopard to a Macbook Pro with Lion, so I am also thinkin in getting everything set up, format the Time Machine with the old stuff and make a new Time Machine.

The Disk Utility can't change the starting point of a partition without erasing it and the data on it.

Changing partition size and migrating to Leopard

My iMac currently runs OS 10.9 and has boot camp installed, but I chose a Windows partition size that was too small (only a few GB, enough to install Windows XP). I am now want to increase the size of the Windows partition and to install Leopard. What is the best order for me to change the partition size and install the new system? If the disk needs to be wiped clean to do this, what is the best way to back up the existing data and then to reinstall it. Would I use migration assistant?

If your beta Boot Camp Assistant hasn't expired, you COULD do this before you upgrade to Leopard. If it has, you can play games with the date, or you can do this after you're on Leopard.
Either way, if your partition is FAT32 you can back it up using Disk Utility, according to other posts (see especially backup/clone discussions in the beta discussion forum); if it's NTFS, Winclone is probably the way to go. If it's a real small partition, though, you might just start over, or back up only what's "yours".
On either the beta or Leopard, you'd want to back up or clone the current Boot Camp partition, remove it using BCA, create the new larger partition using BCA, and then restore the contents.
None of this requires wiping the MAC OS disk, it DOES essentially wipe out the WINDOWS disk. I don't think Migration Assistant helps here, but certainly haven't tried that.

Change partition sizes after windows has been installed

After I have installed windows onto my mac and have created the partitions, can and how do I change the size (in terms of memory) of the partitions without reinstalling all information?

Hi and welcome to Discussions,
you can use WinClone for this http://www.twocanoes.com/winclone/ and in here http://www.twocanoes.com/forums/viewtopic.php?t=515 you find a how-to.
(Topic: My current Windows partition is the wrong size, and I want to make it larger. How do I do this?)
Other people have used CampTune http://www.paragon-software.com/home/camptune/ successfully.
Prior to doing this you should make/have a backup of your OSX and Windows files for safety.

Changing Partition Size without Deleting (bootcamp)/ Vista Question

Hi, I'm currently running windows xp and OSX together with bootcamp on my black macbook (2 gigs of ram).
I want to install Vista but I don't have anymore space on the Windows XP partition (just 4.42 gigs left). Can I partition my drives again where I get more room for my XP drive without deleting or messing up any of the information?
Also , can I even use vista ultimate upgrade on my macbook?

Hi,
I believe boot camp is not supporting upgrade version of windows OS.
Run you boot camp assistant to changed the partition size, but I think it will delete all of the XP that already installed there, but you don't need that again if you want to install Vista in that partition right?
do visit boot camp forum for more answer from their experienced user.
Good Luck

Changing partition size without reformatting drive?

I heard a rumor that in Leopard you can change the size, name, or other details of a partitioned HDD without having to erase and reformat it.
Is this correct? If so, that would be a huge advantage for me, as I often don't predict how much drive space I'll need to use.

Tell me if I'm wrong, though, but it seems that DU can only shrink. So, if you have 2 partitions, after you shrink one, you can't increase the size of the other. I hope I am wrong here. Please let me know if your experience is different. I think we'd all like to know how it goes, regardless.
That said, VolumeWorks can do as you require. DO NOT do this without a backup of everything.

Cannot change partition size on firewire external drive

My external firewire drive has three partitions, one of which is used for Time Machine and is out of space; the third one is empty. When I use Disk Utility to try to increase the size of the second partition without erasing its contents, I get the message: "Partition failed with the error: filesystem resize support required, such as HFS+ with journaling enabled".
Can someone please advise me on how to proceed.

How have you formatted your drive?
My drive is formatted as Mac OS X Extended (Journaled) and I have not trouble resizing my partitions with disk utility. I remember reading somewhere that certain formats do not support on-the-fly resizing. If you are using one of those formats (which I would guess based on your error message), you may need to re-format your drive. This would mean erasing everything (so make sure you back up your drive first). If you do have it formatted in the same way as me, I am not sure why you are getting the error.

Changing partition sizes

I have two partitions on my 320 GB hard drive, and want to make one smaller and one bigger. When I try to resize them all I can do is make them smaller. When I make one smaller, it displays a bluish section between the partitions, which I assume is "nothing," but then I can't make the other partition any bigger. Is there a way I can do this? I don't want to erase the whole thing and redo the partitions.

I have tried, and it doesn't let the 2nd (or lower) partition inherit the space that was used previously by the partition above.
Seems like a natural enough idea, but of course the safest is to backup and restore.
Also, if you use BootCamp, don't, and resizing or creating partitions in OS X or Windows can have side-effects, like Windows OS partition no longer showing.
Partitions - or their use - always change over time, which is one of their downsides.
Apple Disk Utility Restore or other programs make the backup / reformat / restore easy and painless. I'd recommend checking into SuperDuper.

Satellite A350: How to change partitions size on HDD?

Hi,
I have a Satalite A350 with a 250G Harddrive, but for some reason it has been partitioned with 114g for C drive and a huge 114g for E drive which is just the recovery drive. I'm now down to 20g on the C but still have an untouched 100g on the E.
I assume that my computer has been incorrectly partitioned, and I know I can shrink the E but will this increase the C?
Cheers

Hi
As far as I know you can shrink the partitions in Disk management (Vista and Win 7).
But if you shrink the E partition then the free space would be available after the E partition and you will not be able to add this free space to the C partition which is placed behind the E partition.
But maybe a 3rd party partitions tool could help you
There is a nice free tool called Gparted.

Maybe you could test this!

Changing partition size of boot disk

Hi, i have an imac 5.1, i use an external drive to boot from which has 2 partitions, the one i boot from and the other part has files and stuff. i want to make the boot disk space bigger and the other smaller, how would i do this? thanks.

The idea of seperating the data from the system is a poor reason to partition the system drive.
Backup the data.
Reformat to a single partition and restore the data.
This will allow OS X to handle disk space for you instead of you having to do it.

Can I change the sizes of my bootcamp/Mac partitions?

Is it possible to move more of the space on my Windows partition back to my Mac partition without reinstalling everything? I'm spending next to no time in Windows at all, and I want more space on my Mac partition because it's where I store all my media.
Basically, I want to redefine the partition sizes.

Yes it is.
The best app is iPartition, but you have to pay for it.
Otherwise, how good are you with the command line?
I think disk utility has an option as well.
Actually, there are rules on where you can move / change the data. It has to come directly after the partition you want to resize.. IIRC

Changing the size and/or erasing a disk partition

I have a 2010 MacBook Pro with two disk partitions. The original is 100G and runs Mavericks, and the other is 200G and runs Snow Leopard. I can change the size of the partition with Snow Leopard that I created but not the original. In the end I need the partition running snow leopard to be 100G and the original with Mavericks to be 200G. Essentially swap the size. Do I need to erase the partition I created to change the size of the original. If so, what is the best way to do this?

This is Apple's guidance on disk partitioning.

Change Volume size after partition

I just formatted a drive and partitioned it. I haven't add any data on both of them and I changed my mind about the size of them.
Is it ok to change their sizes in disk utility? or would be better to format them again and repartition?
thanks in adavance

You can repartition the drive. Since there's nothing on the drive repartitioning won't cause any loss of data.
