How to burn ISO disc images on Mac

admin — Sun, 23 May 2010 23:27:07 +0000

Disc images are a fairly common packaging standard for large software programs. If you want to try out a new Linux distribution, for example, chances are you’ll need to download a disc image in ISO format and burn it to a blank CD-ROM or DVD.

But ever since I began using Mac OS X, I’ve been perpetually confused about how to burn ISO images. I’m used to disc burning utilities that have an obvious, explicit command like “Burn ISO Image to CD.” To make life even more confusing, OS X’s Disk Utility does have a Burn command, but it becomes disabled when you click on the blank disc you’d like to use for the burn.

The problem here is that most Mac disc utilities, including the built-in Disk Utility, take a different approach when it comes to image burning. Instead of telling the program you want to burn an image, then choosing the file, you’re supposed to do the reverse: You choose the file, then tell the program you want to burn it. So, to burn an ISO image to disc, here’s what to do:

Insert a blank disc.
Start Disk Utility.
From the File menu, choose Open Disk Image and select the ISO to be burned.
In the list of volumes, you will now see an item representing the ISO file. Select it.
Click the Burn button and follow the instructions.

That’s it! Sure, it may seem simple enough, but when you’ve been using Linux and Windows utilities for years, these steps can be a little perplexing and hard to remember.

You can do the other way as below,

Open the ISO image with Disk Utility (e.g. via “Open with” in the finder context menu).
Select the image in the drives list in Disk Utility.
Hit the “Burn” button and insert a blank CD.

Win XP Set Permissions On Files Or Folders

Turning on and turning off Simple File Sharing

Simple File Sharing is always turned on in Windows XP Home Edition-based computers. By default, the Simple File Sharing UI is turned on in Windows XP Professional-based computers that are joined to a workgroup. Windows XP Professional-based computers that are joined to a domain use only the classic file sharing and security interface. When you use the Simple File Sharing UI (that is located in the folder’s properties), both share and file permissions are configured.

If you turn off Simple File Sharing, you have more control over the permissions to individual users. However, you must have advanced knowledge of NTFS and share permissions to help keep your folders and files more secure. If you turn off Simple File Sharing, the Shared Documents feature is not turned off.

To turn Simple File Sharing on or off in Windows XP Professional, follow these steps:

Double-click My Computer on the desktop.
On the Tools menu, click Folder Options.
Click the View tab, and then select the Use Simple File Sharing (Recommended) check box to turn on Simple File Sharing. (Clear this check box to turn off this feature.)

Ejecting stuck CD or DVD from Mac OSX

admin — Sat, 13 Mar 2010 11:34:57 +0000

From time-to-time, removable media (including CDs, DVDs and others) can refuse to eject via the normal Mac OS X methods — pressing the keyboard eject key; using the Command-E keyboard combination; selecting the item in the Finder and clicking the Eject button next to its name; dragging the item to the trash; or pressing the F12 key.

A number of methods can be applied to help coax media out of an optical drive in such a situation. Before applying these methods, however, note that busy disks (either startup disks or disks with an open file) should not be ejected and will not using any of the aforementioned standard processes. As such, be patient with a disk that will not eject immediately. Sometimes a disk continues to be identified as busy for several seconds after any contained files are not in use, and waiting a few moments then re-attempting the ejection is successful.

Use Disk Utility to eject
The first and simplest method, if you only want to unmount a single volume on the disk, is to use Disk Utility, located in Applications/Utilities. In Disk Utility, simply select the volume you want to unmount and click Eject.

Hold Down the mouse button at startup
In some cases holding down a connected mouse button at startup will cause a misbehaving optical drive to eject its media.

Unfortunately, this method will not work if you are using a Bluetooth keyboard.

Also, for Xserve users, make sure that the machine is unlocked (using the included allen wrench) before holding down the mouse key during startup.

Boot into Open Firmware and eject
If you have a Mac that will not startup properly and has a stuck disc, try booting into Open Firmware by holding down Command, Option, O key and F key during startup. After booting into Open Firmware, type the command eject-cd.

Using the Terminal
There are two commands that can be used in the Terminal (located in Applications/Utilities) which can be used to force disk ejection:

The first command to try is drutil tray eject. Simply type in this command and press return.

The other method takes a little more work but can work in instances where the first method fails.
In the above command, the number “1″ should be replaced with whatever drive number you obtained in the first step.

Enabling an Eject menu
As a side note, you can enable another means of ejecting disks by opening the folder System/Library/CoreServices/Menu Extras and double-clicking the file “Eject.menu”. An eject icon will appear in the menubar that can be used to close and open selected optical drives.

If you no longer want the Eject menubar item, hold down the command key while clicking and dragging the icon out of the menubar space.
