OS X Recovery Disk Assistant v1.0 Download

Built right into OS X, OS X Recovery lets you repair disks or reinstall OS X without the need for a physical disc.

The OS X Recovery Disk Assistant lets you create OS X Recovery on an external drive that has all of the same capabilities as the built-in OS X Recovery: reinstall Lion or Mountain Lion, repair the disk using Disk Utility, restore from a Time Machine backup, or browse the web with Safari.

Note: In order to create an external OS X  Recovery using the OS X Recovery Assistant, the Mac must have an existing Recovery HD.

To create an external OS X Recovery, download the OS X Recovery Disk Assistant application. Insert an external drive, launch the OS X  Recovery Disk Assistant,  select the drive where you would like to install, and follow the on screen instructions.

When the OS X Recovery Disk Assistant completes, the new partition will not be visible in the Finder or Disk Utility. To access OS X Recovery, reboot the computer while holding the Option key. Select Recovery HD from the Startup Manager.

Learn about Recovery Disk Assistant.

The Recovery Disk Assistant lets you create Recovery on an external drive that has all of the same capabilities as the built-in Recovery: Reinstall OS X, repair the disk using Disk Utility, restore from a Time Machine backup, or browse the web with Safari. This drive can be used in the event you cannot start your computer with the built-in Recovery HD, or you have replaced the hard drive with a new one that does not have Mac OS X installed.

System requirements

• A Mac running OS X Lion or Mountain Lion with an existing Recovery System on its startup volume.
• An external USB hard drive or thumb drive with at least 1GB of free space

How to use Recovery Disk Assistant

The Recovery Disk Assistant will erase all data on the external drive when creating the Recovery HD. You should either backup your data before running the Recovery Disk Assistant, or create a new partition on the external drive.

If you need to create a new partition on the external disk

1. Open Disk Utility, located in the Utilities folder in Launchpad.
2. Select the drive on which you would like to install the Recovery HD and add a partition. Note: Partition should be at least 1 GB in size.
3. Click Options and make sure GUID Partition Table is selected.
4. Make sure the format for the partition is Mac OS Extended (Journaled).
5. Click Apply.

Open Recovery Disk Assistant and follow the on screen instructions to create a Recovery HD on the external drive.

When the Recovery Disk Assistant completes, the new partition will not be visible in the Finder or Disk Utility. To access the external Recovery HD, connect the drive, then restart the computer and hold the Option key. Select Recovery HD from the Startup Manager.

Notes

• If the computer shipped with OS X Lion or Mountain Lion, the external recovery drive may only be used with the system that created it.
• If the system was upgraded to Lion or Mountain Lion purchased from the App Store, the external recovery drive can be used with other similarly-upgraded systems.

At some point, you may find a need to boot your Mac from a disc or a drive other than the primary Mac OS X startup volume. Apple made it easy so all you need to know is just a simple keyboard command.

Let’s say you need to use the Mac OS X installation disc that came with your computer to reformat the hard drive and put it back to factory settings. Or maybe you’re trying to boot from a USB flash drive that has a clean install of OS X on it for troubleshooting purposes. Perhaps you’ve got a cloned backup of your entire Mac on an external hard drive and you want to make sure it’s bootable. These are all potential reasons for booting to an external device, among many others.
There easiest way to boot to any device other than a Mac’s internal hard drive is to press and hold the Option key immediately after hearing the Mac startup chime. Continuing to hold this button down will bring up a menu where you can select a disc or drive to boot from. Use the keyboard arrows to choose your boot device, then press the Enter key. The computer will start up from the chosen volume, but bear in mind performance will likely be much slower than when you normally operate your Mac. This is especially true of USB flash drives.
Rather than hold the Option key, you could instead just press & hold the C key if you’re booting from a CD or DVD disc. This will bypass the selection menu and immediately start from the disc. It won’t work for USB and FireWire drives, though.
Booting to another volume using either of these methods is a one-time temporary change, so you don’t have to worry about altering any settings to reverse it. Your Mac will go back to booting to it’s primary startup disk next time you reboot.

How to format a drive for Mac and PC compatibility

Posted by Ant on March 11th, 2012 at 3:14 PM  | 

If you have an external hard drive or USB flash drive that you’d like to use on both Macs and Windows PCs, choosing the right file system to format the drive can be confusing. Learn a few ways to make your drive Mac and PC friendly.

Need to access or transfer files between Mac and PC? As simple as this task sounds, it’s not very straightforward for inexperienced users. Since Mac OS X and Windows use totally different file systems, the way a drive is formatted can determine what type of computer it will work with. In fact, there are four ways you can format an external or USB flash drive to achieve varying degrees of compatibility between Macs and PCs. Let’s take a look at them:

HFS+

Mac OS X’s native file system is HFS+ (also known as Mac OS Extended), and it’s the only one that works with Time Machine. But while HFS+ is the best way to format drives for use on Macs, Windows does not support it. If you’re only going to be using your external or USB flash drive with certain PCs – such as at home or the office – you might be interested in a program called MacDrive. When you install MacDrive on a Windows PC, it will be able to seamlessly read & write to HFS+ drives. This isn’t a good solution if you need your drive to work on any PC without installing software, though.

NTFS

The native Windows file system is NTFS, which is only partially compatible with Mac OS X. Macs can read files on NTFS drives, but it cannot write to them. So if you need to get files from a PC to your Mac, NTFS is a decent option. However, you won’t be able to move files in the other direction, from Mac to PC.

FAT32

The most universally supported way to format your drive is with the FAT32 file system. It works with all versions of Mac OS X and Windows. Case closed, right? Well, not so fast. Unfortunately, FAT32 is a very old file system and has some technical limitations. For example, you cannot save files that are larger than 4GB on a FAT32-formatted drive. This is a deal-breaker if you work with huge files. The other limitation is the total size of the partition. If you format your FAT32 drive in Windows, the drive partition cannot be larger than 32GB. If you format it from a Mac running 10.7 Lion, the drive partition can be up to 2TB. Much better, except for that pesky 4GB limit.

exFAT

The exFAT file system eliminates the two major deficiencies of FAT32: the largest partition and file sizes it supports are virtually unlimited by today’s standards. Awesome, it’s perfect! Almost… since exFAT is fairly new, it isn’t compatible with older Macs and PCs. Any Mac running 10.6.5 (Snow Leopard) or 10.7 (Lion) supports exFAT, while PCs running Windows XP SP3, Windows Vista SP1, and Windows 7 are compatible. If you know you’ll be using computers running updated versions of these operating systems, exFAT is the clear best choice.

Format a drive using Disk Utility on a Mac

1. Launch Disk Utility (Applications > Utilities).
2. Select your external hard drive or USB flash drive from the list on the left.
3. Click on the Erase tab. Select the format – Mac OS Extended (HFS+), MS-DOS (FAT32), or exFAT – then name the drive.
