How do I re-partition my iMac hard drive?

Originally partitioned my 1TB internal to 250GB/750GB. Now it seems I need more space for my boot partition. I've used Time Machine to BU. So do I have to completely erase, booted from my Snow Leopard install disks, partition like I want to, and then use my Time Machine BU to re-install all my stuff? Will it recognize my new partition and put each BU disk into its' proper place?
Thanks!!!

It depends on which partitions are where, and which ones you want to keep/move/change.
With Disk Utility, you can expand a partition without erasing it if it's not the last one on the drive.
So if the diagram shown by Disk Utility when you select the top line for the drive, then the Partition tab shows partition A on top and B on the bottom, you can delete B and expand A to fill the drive. Then click the plus sign at the bottom to split the expanded A, and set the sizes as needed. Then you'll only have to restore B.
It's not quite the same thing, but there are a couple of screen prints in #6 of Time Machine - Frequently Asked Questions (or use the link in *User Tips* at the top of this forum), that should give you the general idea.
But if the partitions are arranged the other way, yes, you must completely erase and repartition.
I'd strongly agree with Thomas that you should have a second backup before starting this, just in case something goes wrong. It's unlikely, but does happen on occasion.
I'd also agree that in most cases OSX works much better with OSX, apps, and data in a single partition; Apple's engineers spend lots of time optimizing it to do just that. There are exceptions, of course, but one big pot is usually better than two small ones.
To restore your boot partition, see #14 in the FAQ; to restore a data-only partition, see #15.

How to remove a partition of my hard drive

I have an old 2007 HP Pavilian DV6000 series with Windows Vista. At some point, one of my husbands friends had the bright idea to partition the hard drive and put Linux (Ubuntu) operating system on my laptop. I haven't used this laptop in a few years now because once he did that the laptop has been screwy ever since. I want to remove that OS and remove that partition. I don't have a recovery disc to do a factory reset, I've tried that and I've tried restoring to early point and nothing is working. So how can I un partition that part of the hard drive and remove that horrible OS?? Vista is still on there and I can still access Windows, but I just want my computer back to how it should be. Thanks!

How to erase a early 2008 iMac Hard drive when the screen is dead

My early 2008 iMac's Graphics Module has died for the third and last time. I want to erase the Hard Drive before I offer it up for sale as parts or just re-cycling. But with the Graphics Module dead it will not boot up, therefore no display. So how do I erase my data and restore to a clean OS?

Make sure that your old Mac will boot into disk mode then buy this Thunderbolt to Firewire Adapter

How can I share my entire iMac hard drive over a network to my Macbook Pro?

I tried setting up a network, and I was able to successfully transfer a couple of files...but some files just wont transfer to my Macbook when I try to transfer them.
What gives? It tells me on certain files that I cannot get them because I dont have correct permissions. When I command-I to get the folder/file info...I'm not even able to change priviledges to "READ & WRITE". "READ" is the only option available.
Can someone please point out what Im missing? I'm trying to transfer a large amount of files from my imac to macbook pro so that I can sell my iMac. It's not letting me transfer all of them.
Thanks in advance everyone!

and how do I log into the other computer as an administrator? the files i want to transfer i just movies, music, documents, etc.
Two methods:
1) Log into the other computer using the username of an administrator on that computer
2) Log into the other computer using the username of the account that holds the movies, music, documents, etc.

Create two partitions on one hard drive?

Hi
I have an external hard drive I want to use for both PC and Mac.
Can somebody please help me on how to create two partitions on the hard drive, one with Mac extended format and one with NTFS format.
Many thanks

No need to format to NTFS, you can convert to NTFS with no destruction of data.
Just format to FAT in Disk Utility, then when accessing the FAT drive in WIndows:
*To convert a volume to NTFS from the command prompt*
http://technet.microsoft.com/en-us/library/bb456984.aspx
Open Command Prompt. Click Start, point to All Programs, point to Accessories, and then click Command Prompt.
*In the command prompt window, type: convert drive_letter: /fs:ntfs*
For example, typing convert D: /fs:ntfs would format drive D: with the ntfs format. You can convert FAT or FAT32 volumes to NTFS with this command.

In addition, I'd like to partition the external hard drive so that Time Machine can use it to both back up my IMac and the external library drives. Is this possible? Can I set up a RAID 5 format for redundancy?

I'd like to store my Aperture /IMovie Libraries on an external hard drive.
That is fine and recommended.. use the fastest disk you can afford.. ie Thunderbolt>USB3>FW800>USB2.
In addition, I'd like to partition the external hard drive so that Time Machine can use it to both back up my IMac and the external library drives.
Let me be clear.. you want to partition the one disk.. use it for TM and move your files to the external disk.. and then backup to the same disk.. You can do it.. but that is not a backup.. that is an experiment in how long you can get away with running files and backups on the same disk before you lose everything.. like Russian Roulette.. pull the trigger enough times and laws of probability will do you in.
You must have backups on a different disk .. otherwise it is pointless.
Can I set up a RAID 5 format for redundancy?
No.. you can buy special USB and Thunderbolt external drives that support RAID..
BUT that is still not a backup.. let me show why.. you make a silly move and corrupt your file in aperture.. it is not that rare.
Raid will corrupt all copies of the files.. it is replicated across all disks.
Delete a photo it is deleted across all disks.. you have no recovery.
Alway, always consider RAID system one disk.. backup onto another disk.. and if the photos or movies are at all important to you.. ie your family .. make another copy and store in a relatives house.. There is no such thing as too much redundancy.

Hi. My iMac hard drive is running Mavericks. I have an old version of Quark Xpress (3.32) which won't run in Mavericks. Can I partition my hard drive and run an older system on one partition, so I can access my Quark? Is that possible?

Hi. My iMac hard drive is running Mavericks. I have an old version of Quark Xpress (3.32) which won't run in Mavericks. Can I partition my hard drive and run an older system on one partition, so I can access my Quark? Is that possible?

Hi ancelau,
QuarkXPress 3 is a Classic Mac OS application, so you need a version of OS X that still supports Classic. I believe 10.4 was the last one.
So if you have an iMac that boots with 10.4, then yes that is possible. I doubt though that newer Macs boot with OS X 10.4.
So why don't you upgrade QuarkXPress 3 to a newer version? I am not just asking that because I want you to spend money with us.
Typically using software that was released almost 20 years ago is just feasible when you keep an environment that was current at the time of release or a few years after, so an older Mac with a operating system present at that time. 20 years in IT is a lot.
So my opinion is that on a new Mac with a brand new operating system you need to use something a bit more current.
How about QuarkXPress 9 (released 3 years ago) or QuarkXPress 10? You are better off with v9, as QuarkXPress 10 only opens v7 and higher (whereas QuarkXPress 9 opens v3.1 and higher).
Or - I am even happy to make an exception - upgrade to 9 and we give you 10 for free? Let me know please.
Thanks
Matthias

I upgraded my imac hard drive to a 2tb drive. how do i use time machine to get my computer back to normal?

i upgraded my imac hard drive to a 2tb drive. how do i use time machine to get my computer back to normal?

Thank you. I followed the faq#14 (using setup wizard from the osx install disk). Everything went just as planned until I woke up this morning and noticed there was no progress on the "transferring documents" meter. It stopped about 1/4 of the way. I can hear the computer working and the bar is somewhat animated like it is advancing but it's not.
Should I cancel and restart or should I wait it out? It already been about 13 hours since I started the process. Do you think it is my time machine or my iMac? Maybe the time machine file is corrupt or something.
Anyway, any help is appreciated. Thanks.

How to put a recovery partition on the hard drive

How can I create a recovery partition on the hard drive of my laptop. I had to reinstall the whole system, and tried to use the HP recovery software they sent me but it quit when it was about three quarters the way finished. I had to use a copy of windows 8 to put the system back on my laptop. After I got it all straighten out, I updated it to windows 8.1 and it seems like the computer runs a lot faster with windows 8.1 on it. Now I need to find away to install a recovery partition on my hard drive.
Thank You

A Recover partition is something the factory places on the computer. It is an image of the factory installation and the software required to restore the computer to a factory like state using that image. You will not be able to create a Recovery partition on your computer unless you use the HP Recovery Discs to return the computer to a factory like state. Please note the HP Recovery Discs and the resulting HP Recovery partition will only contain an image of Windows 8 that cannot be updated to reflect the installation of Window 8.1.
My suggestion is to use the Windows "System Image Backup" utility to create an exact image of the Windows 8.1 partition as it currently is. If your computer developes an issue or you need to replace the hard drive, all you have to do is "restore" the image to the computer. You will need to use an external USB hard drive or other media to store the image. Please see Windows 8.1 Tip: Use System Image Backup for instructions on creating and storing a "Windows - System Image Backup."

How can I partition my external hard drive supporting mac OS in one partition and windows OS in another?

Hello everyone, how can I partition my external hard drive supporting mac OS in one partition and windows OS in another?

OK. Start with:
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to two (2). Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Click on the Erase tab in DU's main window. Select one of the two partitions, preferably the first one, change the Format type: to MSDOS then click on the Erase button.

How do I partition my external hard drive without losing data?

How do I partition my external hard drive without losing the data already on it? I've been using it with Time Machine on my old computer, but want to use it as a regular drag-and-drop type back up on my new computer. Is there any way to basically split the hard drive so I can still access the Time Machine backups on my old computer, but also be able to use it with my new mac? Thanks!

If you reformat the drive all data is lost.
The only way to save the data is to copy it somewhere else during the reformat.
Drag & drop will not backup things correctly.
I suggest you set up partition for each Mac and then point Time Machine to each of the partition for each of the Macs.

How do I copy iTunes from external hard drive to iMac?

How do I copy iTunes from external
Hard drive to iMac?

if your main library is on your external, then when not connected, you wont have access to it.
so first decide, where do you want to keep the files.
E.g. In my case, I keep my files on "C:\iTunes Music".
I have a backup on external "Z:\iTunes Backup". If I format my laptop, this is how I restore everything.
Edit -> Preferences -> Advanced.
The iTunes music folder in selects as "C:\iTunes Music"
I have checked Keep iTunes Music Folder Organized, and also Copy Files to iTunes Music folder when adding to ibrary". Click OK to save and close preferences.
My iTunes list is now empty. I go to file, and select "Add Folder to Library". From that window, I select "Z:\iTunes Backup". iTunes then copies everything from the backup to "C:\iTunes Music". For me, backup is backup, I dont need it to play music.
Now decide this. If you do not want to keep music on C:, but want to only connect the external to update music on your ipod, do this:
In preferences, set iTunes Music folder as "Z:\iTunes Backup", and uncheck Copy files to iTunes Music folder, since they are already there. Then in files, select Add folder to library again to build and update the list.

How do i move itunes to external hard drive to free up space on my imac

I keep running out of space on my imac (320mb)
I have my movies on a Lacie hard drive.
How do I put itunes on the hard drive?
Thanks

iTunes has many components. The two main ones are the application itself (which is what ones means when ones says "iTunes") and the library which is a set of files and folders. I take it you want to move the iTunes library (you cannot run iTunes the application off a non-boot drive).
iTunes: How to move [or copy] your music to a new computer [or another drive] - http://support.apple.com/kb/HT4527
Quick answer if you use iTunes' default preferences settings: Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive. Open iTunes and immediately hold down the Option (alt) key (shift on Windows), then guide it to the new location of the library.
My one hesitation regarding the above is it sounds like you already have some things on the external drive and you have not shared with us the details of your setup. You have already modified itunes from its standard behavior and this can sometimes introduce problems.
