Hi base5700,
The resource below will explain how to resize your Windows partition. In your case, you want to decrease the size of your Windows partition instead of increasing it.

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 to install a new hard drive without bootable disc/usb

Hi- my hard drive has totally failed and although I can get into disk utility it won't let me create images and keeps coming up with input/output errors when I try.
I don't have another mac to work from and have no discs whatsoever even for older OS versions
I've ordered a new hard drive(a seagate 750GB 7400rpm one) but how do I get mountain lion on the new hard drive without any discs? If I just put in my new hard drive will it come up with an option? I have a mid 2009 MBP if that helps

Here is how it helps:
You need the Utilities from Recovery_HD. Your broken Mac can boot from a Thumb drive.
Use this article to download this Utility to copy the Recovery_HD from your older, working Mac to a minimum 1GB USB thumb drive:
OS X: About Recovery Disk Assistant
Then boot the new mac with the thumb drive by holding down Alt/Option, wait wait wait while it draws an Icon for each bootable Volume, choose the Recovery_HD, choose proceed arrow, and use Disk Utility to erase the drive and create GUID partition Map, 1 partition, Mac OS X Extended (journaled). Then install Mac OS X by download.

How do i wipe my hard drive, without the set up disk. im deployed in Afghanistan and dont have access to the disk

i am depolyed and do not have my disk here. is there anyway i can wipe my hard drive without it?

Back up all data, then boot into Recovery mode, launch Disk Utility, select the startup volume, and erase it.

How do i reformat a hard drive without losing anything on it?

I just got a message that I need to back up and reformat my external hard drive. I know very little about this process and would like to know how to do so and if this is possible without losing anything on it.

If you reformat a drive, you will lose whatever information/files are on it. So, the only way to save your info is to copy it to another drive temporarily, reformat your drive (use Disk Utility and format using Mac OS Extended (Journaled) and the GUID Partition scheme under Options) and then you can copy your information back.

How do i reformat a case sensitive external hard drive without losing data

I know there are a lot of posts about this, and i have spent hours trying to find a soloution / understand what people have responded to others, but i can't work this out.
I also have a Buffalo HD (let's call it HD1) that stores my itunes library.
I have a WD My Passport for Mac (let's call it HD2) that backs up my Mac Book Pro.
I have an older WD that has older TM back ups on it from previous computers (let's call it HD3)
I have one spare completely 'clean' WD hard drive (let's call it HD4).
My laptop was really slow and full so i went to Genius bar, they sold me the Buffalo HD and they moved my itunes to it and set it up so it now has my itunes. I used this disk to run two TM Backups before i realised the drive was nearly full, so i bought the WD My Passport HD2.
I now use WD My Passprt HD2 for TM.
I want to MOVE the backups on HD1 to My Passport HD2 as there is lots of space on it. I also want to move my itunes library from HD2 as a back up.
But i can't!!!
After reading for hours, apparently this is because my HD1 is case sensitive, journaled. And it needs to be Journaled to work with TM/OSX or something very confusing. I have read lots of threads about re-formatting / partitioning and all things that are way over my head. But the one thing i do understand is if i reformat HD1, it erases the data.
This is NOT an option as it holds my WHOLE itunes. The Itunes is WAY too big to drag onto my mac book pro and then move it over to HD2 and make that my itunes folder.
HOW THE **** ARE YOU SUPPOSED TO BACK UP THE CASE SENSITIVE DRIVE BEFORE REFORMATTING IT IF IT'S TOO BIG TO FIT BACK ON YOUR COMPUTER? Surely that's the whole point of having an external drive... to back up AND give you more space?
I'm so mad that the apple store did this to me... they should know that case sensitve wouldn't work with a passport... that i would have problems. UGh.
I have options to move the files from HD1 as i have HD2 and HD3 and then also the completely unused HD4... but i can't move anything anywhere due to this case sensitive nightmare.
Someone PLEASE HELP ME.
thanks.

Hi Kappy,
Just wondering if you had any advice for my situation . . .
My time machine backup was backing up to a drive that was "Mac OS X Enteded Journaled, Case Sensitive." I had no idea what this meant, or that it would even cause issues.
I took my computer to the Apple store yesterday, and they wiped it clean. When they tried to restore it from the Time Machine backup drive, it would not work. Their guess is that Time Machine cannot restore from a drive that is "case sensitive."
Any thoughts on how I can convert my time machine backup data from a "case sensitive" state, to a "non-case sensitive" state? I've tried to just drag and drop the files from the case sensitive formatted drive to a new drive that I have that is formatted non case sensitive, but I get the following error message:
"The volume has the wrong case sensitivity for a backup"
I just really want my data back - I thought TimeMachine was the way to go (and was supposed to work) but unfortunately it is not.
Any help you can provide would be greatly appreciated.
Thanks,

How do I swap out hard drives without losing all of my playlists?

I got a bigger hard drive to store all of my music, and can't do a mass switch. I could delete everything out of my itunes and then add all from the new, but then I would lose all of my playlists.

To transfer your current hard drive I like the free application SuperDuper. It makes a bootable copy of everything on your hard drive http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html You'll need a cheap SATA external hard drive case. Put the new drive in the case then format and partition the new drive and clone your old drive to the new one. Check that it's set up right by booting up from the external drive. Then replace your old hard drive with the new one and put your old one in the external case.

Repartition portable hard drive without erasing contents

Hey all,
So recently I accidentally formatted my portable hard drive but luckily I was able to get my files back thanks to this incredibly useful free software called TestDisk (figured I'd give it a plug lol). Anyway, I don't think I recovered the data properly because now my portable hard drive has only one partition which is in Fat32 format. Anyway, I was wondering if anyone knew a way to repartition my hard drive so that I could leave the existing partition but create another one without having to format the whole thing.
Thanks heaps,
djnush

How is the drive partitioned currently - GUID or APM? It is possible to create a second partition without completely erasing the drive, but it depends on how the drive is currently partitioned. And, you need to be running 10.5.8 in order to do it on a GUID partitioned drive. However, if the drive is currently partitioned using MBR or APM, then you cannot do it on the fly. You would have to repartition the entire drive thus erasing any data on the drive.

Partition ext hard drive without losing data

I have just bought my first MacBook. I have an external hard drive with data on backed up from a windows PC and from reading posts see that I cannot transfer files FROM my mac onto this drive as it is not formatted for use with a mac, although can transfer FROM the ext drive TO the mac.
Can I partition it to make a part for the mac and keep the other part for windows use WITHOUT losing any of the data already on there? I was hoping to use this drive to back up the mac using time machine.
Any replies appreciated in a simple form as I'm not that technical!
Thanks

On the fly formatting from NTFS to FAT32 is not possible without loosing data.
Not true. I have converted drives from FAT32 to NTFS, and vis versa, all while preserving the data on the drive. There is a number of ways to do it on a Windows machine. What I don't know is if there is the same software available for doing on a Mac. Since the OP mentions a WinPC, he might still have that capability himself. The one note of caution is that on an NTFS drive, you want to make sure that there are no individual files you want tot keep that are larger than FAT32 can support (4 GB). Here is one solution.

Can I Re-install 10.6 on iMac hard drive without erasing drive?

My OSX based spell check for mail, text edit, and other programs that use the system spell check no longer have any spell or grammer check functions. I have isolated it to know it's the OS spell checking function, so now want to re-install my system. I have found the original system disks, and want to know if I have to wipe my entire hard drive in order erase and then install just the system? I have a Synchronize generated bootable backup of my entire hard drive, but then it will install the current system probably including whatever problems the system software has now. I suppose I can make another back up that is not the bootable kind, but I would really like to not lose all my settings on everything.
Any suggestions?

Installing an OS will not erase user data. With that said a backup is always wise to have. Use your original disks and then update to 10.6.8.
Ciao.

How can I reformat my hard drive if erase and partition don't work in disk utility and I get an error when I try to erase and install from the Leopard install disk? I have had several kernel panics, but the volume shows up in startup disk.

I have had several kernel panics on my iBook G4; the panic message shows up just after the desktop appears. Although the startup volume shows up in Startup Disk, the installation disk reports an error when I attempt an erase and install. Disk utility is unable either to erase or partition the hard drive. The hard drive shows up in disk utility, but the startup volume doesn’t HELP!!!

Do you have the original system discs that came with the iBook when it was new?
Which exact iBook model is it?
You can choose from this list:
http://www.everymac.com/systems/apple/ibook/index-ibook.html
Erasing the disc and installing Mac OS X 10.5 will result in loss of the other applications (such as the iLife applications) which came pre-installed on the iBook.

Clear my hard drive without erasing osx?

I already upgraded to Mountain Lion and want to pass the 2011 MBP after getting my retina. I want to erase everything but the Mountain Lion. Obviously, no disks. Any help?

Any programs you installed are still tied to you or if downloaded from AppStore (copy protected) can't be updated without your AppleID.
Hold command r keys while booting to get into Recovery partition and use Disk Utility there to erase your Macintosh HD partition with a middle or far right (longer) security erase option. This way everything is gone and the next person doesn't assume your identity online or use Data Rescue to recover files that were deleted.
https://support.apple.com/kb/HT4718
Then quit Disk Utility and reinstall Mountain Lion from Apple's servers using your AppleID for the next person to test with.
When they buy the machine do the same thing again, however you can select the far left faster erase function which only takes a few seconds as your previous data was already removed, you just want to remove 10.8 so they have to install it themselves with their AppleID and not yours.
I've covered a full range of deletion options here, including a Paranoid Section.
How do I securely delete data from the machine?

Can I partition an external drive without erasing data?

Can I do this?
Or do I need to have partitioned the drive to begin with in order to not lose my data?
I need it to be a GUID partition map for booting...

I need it to be a GUID partition map for booting
That is a common misunderstanding. An Intel Mac will boot from a disk partitioned with the Apple Partition Map. What you can't do without GUID is use the Apple Installer (which is used for e.g. System Upgrades).
