Yes you can repartition without losing data. Using Disk Utility, perform a repair on your drive to make sure the drive is free of errors (even better, use Diskwarrior if you have a copy). Then unmount your drive but don't eject it. Select the drive in the left hand pane, then go to the Partition tab. On the Partition Layout section click on the "+" to create ...

iPartition For all my partitioning, I use and recommend iPartition. It will allow you to resize partitions without deleting any data. It also works for Boot Camp volumes and other PC disks. With iPartition, resizing a partition is as simple as selecting it, grabbing the resize handle and dragging. Not only that, but if you have several operations to ...

According to this page: http://support.apple.com/kb/PH11102 If the Encrypt checkbox is available, you can select it to keep your backup disk secure. If the Encrypt checkbox is dimmed, your backup disk doesn’t support encryption. Encryption is available only for Time Capsules and for partitions or disks attached directly to your computer and ...

You can use diskutil cs list to show the core storage view of things. Once you have the logical volume UUID for the disk in question, you can use diskutil cs deleteVolume to clean up the reserved space that was allocated to the encrypted data and filesystems. That would allow you to surgically remove the core storage. You could also unmount the filesystems ...

This is getting increasingly harder over time. Instead of creating a bootable Linux partition, I find it much easier to simply install virtualBox and create a Linux virtual machine instead.

A virtual install of OS X Lion runs without issue on Mavericks. All the popular VM software understand Lion as an OS and should let you install it. I don't see you having any problems with this setup as long as your hardware is Mac.

It is definitely possible to partition a single drive into two partitions and have separate encrypted Time Machine backups on each partition for your two individual Macs. The only downside is a single point of failure since there's a single physical drive used for two machines. If anything goes wrong with that disk, both the Macs would be left without ...

This is how to fix the bootcamp windows install error: "Windows could not update the computer's boot configuration." Do not try to fix with a workaround - you'll find solutions of people manually selecting their Windows partition during reboot by holding down the OPTION key. This will work, but you are circumventing the way that apple wanted you to install ...

I also asked on the developer forums and got an answer there (iOS/OS X dev account required to view). The solution was to boot into a recovery partition (⌘ + R), and change the boot disk from the Apple menu. It needed to be changed to my Mavericks install instead of my Yosemite install.

You can't use filesystem commands (cp, mv, ls, etc.) on devices (/dev/*). If you want to copy everything, bit-for-bit, from volume to volume, you'll need an app like Super Duper or Carbon Copy Cloner.

Yes! As the disk is the correct format, it will show in the disk list in the installer (click Show All Disks). You can install any version of OS X on a partition of the correct format, regardless of where the partition is located. The OS X installer doesn't partition the disk for you though; do this first in Disk Utility.

I've had the same problem with a 3TB Barracuda and a 3TB Deskstar. The only fix was to delete the logical volume diskutil CS in the terminal. Also running 10.8.4 on a 2009 Mac Pro (upgraded to macpro5,1 firmware).

Always have a good backup before you attempt any partition and/or filesystem changes! That said, here are some answers to your list of questions. 1. ability to shrink/expand/add/delete partitions safely after both OSes installed, while safely preserving the data By default, Disk Utility allows resizing only through changing the end of a partition (not ...


2

The resizing can be finicky when there is a gap in the space between the partitions. Especially when if not all the logical volumes / partitions are HFS+ format. It's not clear that you will be able to do this without seeing the core storage listing and the normal listing: diskutil list diskutil cs list The first shows how the filesystems are mounted ...

According to a post by SuperDuper's developer, reinstalling OS X over an existing installation adds a missing recovery partition: Actually, you can easily recreate the recover partition by simply reinstalling Lion from the App Store. (This has the additional benefit of updating the recover partition with the most recent data, too.) ...

Try starting up from the recovery partition and repairing the main OS X volume (like Macintosh HD, indented below a drive) from Disk Utility. I had a similar problem, but there was only about 25 GB of disk space classified as "hidden space" by DaisyDisk. When I used Disk Utility to verify the Macintosh HD volume, there was an error about an invalid free ...

My guess is the software did subtraction to show you the value of "hidden space" and the only thing going on is that the operating system user that ran the tool doesn't have read permission in some directories where files are stored and cannot show you a breakdown of those files. Basically, it added up all the files it could count, totaled their size (161.5 ...

You can use the same folder for Mac and Windows versions of iTunes. I would recommend use the exactly same version though. Here is more info on how use it through the network: http://hints.macworld.com/article.php?story=20070424081346722. It's the same logic, but you will be using the same local folder instead a network shared one.

Here's what I would do: Backup your full disk (all partitions) to an external disk using Carbon Copy Cloner or SuperDuper. Copy your home folder back to the main partition (to /Users) using "Paste Exactly": in Finder, go to your home folder on /Volumes/Data HD, select Edit → Copy from the menu, go to /Users (still in Finder), open the Edit menu, hold ...

I figured it out: The partition was hidden (i don't know why...) so i made it visible again: chflags nohidden /Volumes/MY_PARTITION

Sounds like you started to overwrite the drive. The data is probably still recoverable, but, as Graham said, you don't want to do anything to the drive until you attempt to recover the files. A few options: While I haven't used it, PhotoRec looks like a good option, if you are comfortable with the command line. Despite the name, it can recover all sorts ...


2

If there is anything in iTunes that you want to backup, you should buy an additional drive instead. You don't want to have both the data and the backup on the same physical drive. Personally, I'd get another drive rather than mess around with repartioning drives that are not backed up.

Time machine will use "up to" all the partition. So at the beginning there is going to be free space remaining. This free space will lessen with the time. When the partition is full, TimeMachine will delete the oldest backups. So yes I would suggest a partition and yes the Disk Utility will allow you to partition your hard drive with a low probability of ...

Have you tried holding down the option key when you reboot? You can also select the default boot disk from the bootcamp GUI in windows.

OS X Mavericks requires at least 8 GB of free space to install to. At least 15% of free space is recommended for updates and other such things. Therefore, the minimum space for OS X is 9.2 GB, or to be safe, 10 GB. So yes, using Disk Utility to partition before you installed Boot Camp would have meant that you could have made the OS X partition smaller. ...

The partition has to be formatted NTFS. Special set ups like this are better done manually, not with bootcamp. Format the partition NTFS, then startup with your windoze disk and try to install it to the USB drive.

This is what I found to work: Create USB stick using Apple Bootcamp Assistant (and keep it in your machine for the duration of the installation). Follow the entire process (including specifying the size of your Windows partition). When Bootamp Assitant reboots your machine you need to interrupt the installation by holding option until you get a choice of ...

Sorry to hear that rEFIt it broken is Mavericks, I'm sure they'll fix it soon enough. In either case you can still select an alternate boot drive by holding option on system startup. The Mac will show you any devices that are connected and bootable, and you can just pick one to start up on (Likewise from the Startup Disk preference pane in System ...

I also have this issue... MacPro, 3TB drive (Seagate). I have to use the terminal: diskutil list diskutil unmount /dev/disk22 diskutil eraseDisk HFS+ "Macintosh HD" /dev/disk22 etc etc to utilize this drive correctly. (Sorry for all the commands. Posting them just in case it helps someone. Though anyone using those commands better know what they do ...
