It is possible, although not from Apple themselves. A company called OWC seem to specialise in SSD upgrades for macbook's and have upgrades for your model available here These particular upgrades offer greater speed and capacity to some of the stock apple SSD's from 2011.

I would try using rsync from the command line. rsync -av --ignore-errors /Volumes/failingDrive/ /Volumes/brandNewDrive should do the trick. Mind the trailing / at the end of the source. Rsync will not copy files it finds on the destination, so if you call it a second time it will continue where it left off.

First, note that Device Block Size is different from the block size in use by the filesystem. The former value as reported by diskutil refers to the raw block size used by the hardware. I haven't found an easy way to check the latter value by the command line, but you can just create a zero-byte file then do Get Info from the Finder. It will say 0 bytes, but ...

Jean-François Beauchamp's solution doesn't work properly. Something like this would be more appropriate: Testing touch abc1 touch abC1 ls ab* Interpreting Results 1 file - case insensitive 2 files - case sensitive

You can start by turning on the computer and holding down the T key on the keyboard to get into Target Disk Mode, then connect via FireWire or Thunderbolt cable to another Mac which then mounts the hard drive on the desktop to enable you delete or backup files. You can free up space this way, which should then allow you to boot up normally.

You could try booting from the Snow Leopard installation media and free up space from there. It's been a little while since I've used a pre-Lion system, but IIRC, the main drive should be mounted and available from the installation environment. Just don't actually run the installation! If your friend is having problems booting, it's probably worth ...

You could use Apple's OS X Recovery Disk Assistant to create a bootable recovery disk on a USB thumb drive. Since you've backed up to an external disk using Time Machine you could replace the hard drive, boot to the recovery disk on your thumb drive, use the recovery disk to format the hard drive and then reinstall 10.8/Mountain Lion. Once Mountain Lion is ...

There certainly isn't the same amount necessary as the DMG, so you sure can mount a 100GB DMG into a file system that has less (there will be trivial consumptions, maybe a few kb, but nothting that you'll notice). The whole thing works in the way, that the system attaches a file-system driver to the file with the DMG. The driver will present the DMG file ...

I recently did this very thing. I backed up my OS and files to an external drive (not a thumb drive), installed the new drive with new OS, and restored the Time Machine backup to the new drive. The whole process took a couple of hours. The best online video for doing this operation IMO is here: http://eshop.macsales.com/installvideos/mac_mini2011_hd/ ...

Macs Fan Control can set the fan of an iMac (or MacBook, or other hardware) to any speed. The coolest thing that it can also set a fan to sensor-based control depending on your new HDD by reading its S.M.A.R.T. temperature. This free app is much better and powerful than HDD Fan Control, which is currently deprecated but still costs $35. Macs Fan Control ...

The OS X device block size can be determined by executing the following command from a Terminal window prompt: diskutil info / | grep "Block Size" Which will output the following information: Device Block Size: 512 Bytes The file system block size can be determined by using the stat utility: stat -f %k . Which will show you the Optimal file system ...

I'd use the same solution as for syncing, with the option given to rsync to remove the source files. Something like this: rsync -azv --remove-source-files $INPUT $DEST As you mentioned, why reinvent the wheel? rsync checksums each transferred file to be sure it has transferred correctly.

It can be done, but I’m not sure which SKUs it applies to, or that it’s particularly advisable. Both the 2.9 GHz and the 3.1 GHz 21.5″ iMacs have space for a second drive bay, and there’s an iFixit tutorial explaining how to install a second drive. (iFixit usually tear down new hardware within a day or so of release, and have a lot of tutorials ...

From the Terminal app you can use the program srm (secure remove). Simply start Terminal, then type: srm <filename> For more info, take a look at the man page. Excerpt: srm removes each specified file by overwriting, renaming, and truncating it before unlinking. This prevents other people from undeleting or recovering any information about ...

You can use force unmount a drive by running the following Terminal command: diskutil unmountDisk force /Volumes/VOLUMENAME Replace VOLUMENAME with the name of a volume on the disk you are trying to unmount. Following this, attempt to Erase/Partition the drive again in Disk Utility. Note: Using the above command can interrupt file read/writes, which ...

Indeed, there are some differences between cloning the disk and Migration Assistant. As you mentioned, MA will not migrate all the files, which can be both good and bad… Corrupt system files won't be copied if you use MA since you are installing a completely new OS, then copying certain files over. However, be warned that since they won't be copied over, ...

It won't boot, building a hackintosch machine takes more effort than just swapping a hdd. Macs have a different bios than windows pc's and this is not stored on your hdd but in the machine itself. Osx needs this special bios to run and "talk to" the components of your mac. Also, osx might not have the drivers available for the components in your pc. you ...

Some things I would be worried about: While it's true that the MacBook Air does not have a spinning hard drive or a cd drive, it does have moving parts, namely, the fans. These should be pretty stable, but it does show that there are loose things inside the compute that could become broken due to excessive shaking. If the computer is running, then ...

At least 4 GB of the SSD portion of a Fusion drive is left empty at all times. That space is used for incoming writes. If there's less than 4 GB of empty space on the SSD, Core Storage will start offloading data to the HDD. So if all your data is less than your SSD capacity less 4 GB, then you have whatever your SSD capacity is (128 GB on all Apple supplied ...

Over the network it does not matter what file system is used on the hardware drive, because the computer hosting the drive (making it available through the network) will access it. Your Mac will just make generalized requests over the network for files, folders, etc. and the host will access the file system and serve the files. Network requests are ...

When you select the SuperDuper script / copy mode, you can change the scripts, that SuperDuper will run during the copy process. As you can see, a couple of files are omitted: So the temporary and cache files, etc. may have taken quite some space on your old disk. Some other possible reasons could be: SuperDuper omits OSX swap files (/private/var/vm), ...

If you're OK with Command Line utilities, you can always use smartmontools from http://www.smartmontools.org/. You would need XCode to compile them from source (unless someone here knows binary distribution for Mac OSX), but if I remember correctly I had no issues compiling the package. I have an OCZ SSD retrofitted into my MBP 15" mid-2010 and I can use ...

This is a very easy operation that basically is one menu item away. File -> Relocate Originals… So, just connect whatever drive you want to store some photos on and select those photos (by project, album, smart folder, whatever) and then relocate them. A standard file dialog will appear and you can move them to whatever folder you want on the other ...

A few ways to approach.... Clone your existing drive to a drive image on the 1TB (if it has room). As @revolver mentioned, Carbon Copy Cloner is a good tool. Super Duper does very much the same thing. Your choice. Swap drives and then restore. You'll need a boot drive that has your clone tool. The 1TB could do this, or a flash drive, etc. Plug the new ...

From this blog post: A customized .sparseimage file can be made larger than the total capacity of the physical volume on which it originally resides. While the sparse image volume will seem to make that capacity available, attempting to exceed the physical capacity of the underlying volume will result in a disk error: "ran out of space." A couple of ...

Apple's warranty (AppleCare) is specific about what components are user replaceable/serviceable. The hard drive on an older MacBook for instance is user replaceable, AppleCare used to have the option to send you a replacement hard drive along with a disposable ESD wriststrap for you to install it yourself. The difference though is the hard drive in the ...

You have eliminated the possibility of a hardware issue on the hard drive by installing a new hard drive and also by installing the operating system on the previous hard drive via USB. You have replaced the cable connecting the internal hard drive to the mother board, so it's not a cable problem. The only thing left seems to be the hard drive controller on ...

NOTE FOR CASUAL READERS: rm -rf destroys data. Use with caution. rm -rf may appear to go fast, but it is actually recursively going depth-first into each directory and unlinking the files within—the same operation that is used for any file deletion on Unix systems. You can see how rm -rf works by adding the -v flag, e.g. rm -rfv. There's no reason to ...

Internet Recovery If you installed the Internet Recovery firmware update, hold ⌘ cmd + ⌥ alt + R on boot to begin. An image of OS X will be downloaded from the internet, and can be installed on the internal SSD normally. Once this is complete, you can restore your data from your external drive.

possibilities. A: Unmount the disk from the command line. diskutil unmountDisk Lacie would be the command to unmount a disk that has a file system named Lacie on it. You can also refer to the device itself, but devices can vary from one mount to another. unmountDisk will take any file system name as the object but will unmount all other file systems ...
