Resize partitions without erasing existing data

I have one drive (internal), dual partition (OS X 10.5.2 and Vista) and I want to split the volume OS X 10.5.2 in two. I try this using Disk Utility, but one warning was showed: ..changing the partition map may make this disk unbootable using windows"
Is it warning true? What do I expect to happen in case of resizing?
If someone had have any related experience about that, I will appreciate Your advice.

You can resize partitions without losing data but you won't be able to boot into Windows after that. That was a bad experience I had. My first bad experience was to repartition a dual-partition (Tiger+Windows) drive, ignoring the warning. Guess what? Lost everything and had to reinstall both OS.
Mac OS X Extended (journalled) drives can be repartitioned without losing data using the "diskutil" command in the Terminal window. Type "diskutil" and you get a list of available commands.

Hey Mike2793,
Thanks for the question, I believe the following article has the answer you are looking for:
Using iPhone, iPad, or iPod with multiple computers
http://support.apple.com/kb/HT1202
iPod shuffle and iPhone are intended for use with a single computer. You cannot load music from multiple computers or iTunes libraries onto iPod shuffle and iPhone like you can with other devices.

Can't add a new partition without erasing it all.

Hi! I have a problem in Disk Utility in which I cannot add a partition because the plus button is greyed out. I can select to make two partition in the drop down but that would probably erase everything. All I want to do is add one partition to the existing partition without erasing anything so I can dual boot Windows 8. I can't use boot camp because I can only install Windows 7 since my computer is from 2010. Thanks in advance!

Syncing shouldn't trouch you photos unless you have photos in a Photo Library album. These would be photos that were synced to your phone from your computer. If you do have any, you'll need to use an app like PhotoSync to transfer them to your computer prior to syncing.
If you prefer to backup your camera roll photos prior to syncing, open iTunes and go to Preferences>Devices and check "Prevent...from syncing automatically". Then connect your phone to your computer and import them as explained here: http://support.apple.com/kb/HT4083.
Then, to minimize data loss, follow the steps in this user tip: https://discussions.apple.com/docs/DOC-3141. To follow the steps, first open iTunes and go to View>Show Sidebar. Also, Transfer Purchases is now located in File>Devices.

How can I sync with this library without erasing my data?

The iPod "Sayira's iPod" is synced with another iTunes library. Do you want to erase this iPod and sync with this iTunes library? An iPod can be synced with only one iTunes library at a time. Erasing and syncing replaces the contents of this iPod with the contents of this iTunes library.
So, okay, here's my story: My laptop caught a virus, so i sent it to this guy who fixes computers, now that my laptop is fixed, everything is deleted from it. I didn't really mind this too much, but anyway I redownloaded iTunes to my new hardrive and then it said the following (posted above). My question is, how can i sync with this new library without erasing any data from my apps (such as games, photos, videos, music)? I REALLY don't want to lose this data!

- Transffer iTunes purchases to the computer by:
iTunes Store: Transferring purchases from your iOS device or iPod to a computer
- Transfer other music by using a third-party program like one of those discussed here.
Copy music
- Connect the iPod to the computer and make a backup by right clicking on the iPod under Devices in iTunes and select Back Up
- Restore the IPod from that backup
Note that the backup that iTunes makes does no include symec media like apps and music.

Adding to ipod from alternative iTunes catalogue without erasing existing

Is it possible to add music to ipod without erasing existing content that was synced from another PC.
So far i have been alerted that if i sync any new material from my list it will automatically erase what my daughter already has on her ipod.

Connect your iPod to your computer. If it is set to update automatically you'll get a message that it is linked to a different library and asking if you want to link to this one and replace all your songs etc, press "Cancel". Pressing "Erase and Sync" will irretrievably remove all the songs from your iPod. When your iPod appears in the iTunes source list change the update setting to manual, that will let you use our iPod without the risk of accidentally erasing it. Check the "manually manage music and videos" box in Summary then press the Apply button:
Using iPod with Multiple computers
Managing content manually on iPod
Syncing Music to iPod
You can also use a keyboard command to prevent your iPod auto-syncing with iTunes. While connecting the iPod to the computer on Windows with iTunes 7.3 or later installed hold down the Shift + Ctrl keys together. This will stop the iPod from auto-syncing with iTunes and the iPod will appear in the source list. Wait until you are sure the iPod has mounted, and that it will not auto sync and then you can let the keys go. This may take between 20 to 30 seconds depending on your computer. Once you are connected you can change to manual as above: iTunes - Keyboard Shortcuts for Windows
Something else to be aware of when using an iPod in manual mode is that the "Do Not Disconnect" message will remain on the display until you physically eject the device: Safely Disconnect IPod

I wanna ask you something. My bro has an iPhone 5s that disabled for 23 million because of the time changed to 1976. So, how to make it back into 2015, make it enabled without erase the data

I wanna Ask you something. My brother has an iPhone 5s that disabled for about 23 millions minutes the time changed to 1976. So how to make it back into 2015 without waiting for 23 millions minutes later and enabled it without erasing any data? Please answer me ASAP because I really need it. Thank you for answer!

Hello theshadowhunters,
There is not much you can do to change the time back because he will not have access to change the time. The only option to get passed this is to restore the iPhone. Once the iPhone is restored and have a back up, you can put that back on once the restore is complete. For more information, take a look at the article below.

How to reinstall snow leopard without erasing any data

Hi, I have a mac running snow lepoard and want to reinstall the operarting sytem without erasing any data, can you tell me how to do that, thanks.

Just boot from the install DVD and install. This will give you the version as of the version on the DVD while preserving your third party software and users. Then update using Software Update. Better to do this with a backup in case anything goes wrong.
Why do you want to do this? I wonder if this is really needed.

Can I create a mirrored RAID1 from an existing striped RAID0 without erasing the data?

I have a 1.5 TB striped RAID0 with 3 500 GB drives. I have a clone of the data from the 1.5TB RAID on a non-RAID 1TB drive and a 500GB drive. I'd like to create a RAID1 mirrored set out of all of these disks. I can partition the 1TB into 2 500GB drives and combine that with the other 500 GB. I'd rather not erase the data to create the mirror. Is there a way to rebuild a mirrored set from the existing 1.5 TB striped set, or do I need to start all over? I have a third copy of the data that I could put on the new mirrored RAID if necessary.
The data is aperture, itunes and imovie libraries. To back up a minute, is having a RAID1 a good option or is there a better solution that I am not considering?
PS I'm using a 2.53 GHz macbook pro unibody with 8GB of RAM.

First off a mirrored RAID requires two drives of equal size (could be two striped RAIDs of equal size.) So, as I understand what you have to work with you can create a single 500 GB mirrored RAID using two of the 500 GB drives.
You could create a striped RAID array using two of the 500 GB drives, then combine it with the 1 TB drive you have to create a 1 TB mirrored RAID. But this would not be the best alternative because if one of the smaller drives in the striped array fails then you lose everything on those drives. Not so bad as long as the single 1 TB drive is OK.

Hardware or Software RAID?
RAID Hardware Vs RAID Software - What is your best option?
RAID is a method of combining multiple disk drives into a single entity in order to improve the overall performance and reliability of your system. The different options for combining the disks are referred to as RAID levels. There are several different levels of RAID available depending on the needs of your system. One of the options available to you is whether you should use a Hardware RAID solution or a Software RAID solution.
RAID Hardware is always a disk controller to which you can cable up the disk drives. RAID Software is a set of kernel modules coupled together with management utilities that implement RAID in Software and require no additional hardware.
Pros and cons
Software RAID is more flexible than Hardware RAID. Software RAID is also considerably less expensive. On the other hand, a Software RAID system requires more CPU cycles and power to run well than a comparable Hardware RAID System. Also, because Software RAID operates on a partition by partition basis where a number of individual disk partitions are grouped together as opposed to Hardware RAID systems which generally group together entire disk drives, Software RAID tends be slightly more complicated to run. This is because it has more available configurations and options. An added benefit to the slightly more expensive Hardware RAID solution is that many Hardware RAID systems incorporate features that are specialized for optimizing the performance of your system.
For more detailed information on the differences between Software RAID and Hardware RAID you may want to read: Hardware RAID vs. Software RAID: Which Implementation is Best for my Application?
Do You Really Need a RAID?
There is only one thing a RAID provides - more space. Beyond that a RAID can’t help you with:
Accidental deletion or user error
Viruses or malware
Theft or catastrophic damage
Data corruption due to other failed hardware or power loss
Striped RAIDs have a higher failure risk than a single drive
The purpose of a RAID is to provide high speed mass storage for specialized needs like video editing, working with extremely large files, and storing huge amounts of data.
If your array fails it means complete loss of data and hours of time to rebuild. RAIDs degrade over time necessitating many hours of restoration. And, if you don't know much about RAIDs then you really don't need one.
You can use a RAID for backup. But unless your backup needs involve TBs of data requiring rapid and frequent access, why bother? TM works in the background. It's not like you have to sit there waiting for your backup to be completed. Furthermore, you're buying two drives possibly to solve a problem where a single drive will do. And, one drive is less expensive than two.
Ignoring overhead, two drives in a RAID 0 (striped) array should perform about twice as fast. However, as the array fills up with files that performance will degrade.
RAID was a technology that in it's time was meant to solve a problem. Large capacity, fast drives were extremely expensive. Small drives were cheaper but slower. However, combining these cheaper drives into arrays gave faster performance and the larger capacity needed for data storage needs. Thus, the reason why it's called Redundant Array of Inexpensive Drives. But today you can buy a 3 TB drive with performance that's better than the 1 TB drives of two or three years ago.

Partition without erasing disc?

Is there any way to partition a disc without erasing and reformatting? I'm afraid I already know the answer but thought I'd ask anyhow?
Steve

Hi Steven:
As noted, there are a couple of utilities. Drive Genius (from Prosoft Engineering is one, and DiskStudio (from Micromat) is the other.
I've tried Drive Genius once, and was not happy with the results. The new partition with the OS on it booted fine, and I could use the second partition for data, but neither Disk Utility or any Mac OS installer (OS 9 or Panther) would see either partition.
I haven't tried DiskStudio yet, so I don't know whether it's any better. I trust Micromat's other tools (esp. TechTool Pro), but until I have an opportunity to test it on a new system, can't recommend it.
The best solution by far is to clone your system to an external firewire hard drive, partition your internal drive with Disk Utility, then clone your system back.

How can i add songs to a family members ipod without erasing existing songs

How can i add songs to a family members ipod without erasing her existing song list.

For future reference, since I came here for the same reason, I'd like to add to the solution. The link was not complete in explaining how to, but then again I'll just trying to attempt to fill in the gap.
After opening iTunes, on the upper left hand side is a small icon with an arrow pointing down. Click on the arrow and a menu pops out. Click on "Show Menu Bar." On the new bar(Older iTunes File, Edit, View, Controls, etc. bar at the top). Click on View and then Show Side Bar. There you can just click and drag new songs into your iDevice without any problems... hopefully...
Seriously, this helped me, so if Apple finds a way to not allow me to do this simple task of adding purchased songs into my idevices from another computer, I'll have to resort to other means.
The one idevice that's having trouble with is my iShuffle(2nd).

SYNCING MY NEW SONGS WITHOUT ERASING MY DATA AND SONGS

So here is the deal my pc have some issues during some months and is where i synch my music with my ipod touch, ipad and also ipod. Then i send it to service to format it and then my pc was new. And when i have already purchased some songs from the store and when i tried to sync again my devices (ipod, ipad and ipod touch) I could but it asked me if i want it to sync and erase all my songs and data from my ipod in which i didnt want because i have around 100 songs wich i have already bought and downloaded in that same pc. So how can i sync my ipod, etc with another pc in this case with mine without deleting my data and songs?
Note: I have Windows 7

You can only sync to one computer/iTunes library. The iPod not thinks that this computer/iTunes library is a new one. Do the following to not lose anything
