If i created an image of my mac hard drive onto an external hard drive would it delete everything on it
please someone help me. its just a yes or a no but im unsure an dont want to go ahead untill im sure!!
If you did it right, then yes it would first erase the external drive:
Clone using Restore Option of Disk Utility
1. Open Disk Utility in the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag it to the Destination
entry field.
5. Select the source volume from the left side list and drag it to the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.

Installing Mac OS X onto an External Hard Drive
Will installing Mac OS X onto an external hard drive erase or mess with in any way files that are already on the external hard drive?
Can I safely install Mac OS X to an external hard drive that already has stuff on it to make it a bootable volume and still be able to access those initial files on the hard drive?Will installing Mac OS X onto an external hard drive erase or mess with in any way files that are already on the external hard drive?
Not unless an Erase & Install is performed.

I had all photos on a Windows desktop. Got a mac laptop, installed LR5, and put all images from Windows onto an external hard drive. When I go to import them into LR on the mac, they are all locked. Help, please!
"I plugged the external into the Mac and moved a folder of images onto the desktop. It looks like it went from read only to not locked. Is this possible?"
Yes, that's exactly what happened. If you buy another drive, you could copy from your existing drive to the new and your files will be read/write. The new drive will have to be formatted as an HFS drive (that's the Mac's format). If you need to format it, you use Disk Utility which is in the Utilities folder on your Mac. Be careful with that -- it wipes out whatever is currently on the drive. Make sure you format the right drive.
I keep all my images on an external drive, too. In fact, I have two matching drives and sync them so I always have a backup. -
Hello, I have two questions on time capsule I can only have it on my external hd files and free up my internal memory to my mac I can use an external hard drive, in my case a lacie rugged as shared memory for my two computers
I have a mackbook pro and an iMac if I buy a time capsule 2tb airport, I can use it with time machine and what would be the best way to use it.
There is no particular setup required for TM.. both computers will create their own backup sparsebundle which is like a virtual disk.. Pondini explains the whole thing if you read the reference I gave you.
and how to use time capsule airport whit other external hd to use my old lacie airport with the new time capsule
Up to you.. you can plug the external drive into the TC and enjoy really slow file transfers or you can plug it into your computer and use it as external drive.. which is faster than the TC.. and TM can include it in the backup.
Again everything is explained in the reference.. you are not reading it. -
I am new to MAC. I have an external hard drive that I used with my former computer running Windows XP. Can I reformat it to use with my new MAC? If so, how do I do it?
Yes you can. See the following:
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size. -
Mac newbie cannot access Mac Mini's Iomega 200gb external firwire drive
After a power problem - I powered on my Mac Mini to find no external firwire drive
I have my data backed up - so I reinstalled OSX
I am now at the stage where Disk Utility
can see the disk,
I ran disk repair - it said all ok
but no icon on desktop (I am logged in as Admin)
I plugged in my work usb disk its icon appears ok
the firewire reports its mount point: /Volumes/Iomega HDD
when I safari that it returns "you dont have permission"
but when I safari my usb drive I get to see its contents
it looks like I (admin) dont have permission on the disk - and "repair disk permissions" is not clickable
Its a step forward but I'm stumped - on the plus side I am learning OSX's quirks having been a micro$oft user for so long and was pleasantly surprised with os reinstall ease.
also finder finds all my stuff (but its in ghost font - unclickable ! )
is there some utility to force admin permission?
or am I thinking about this the wrong way?
I also am not too worried about reformatting the disk, as I have 99.9% of the data backed up (the only thing I thank my years of Micro$oft use for lol)
however a part of me thinks a reformat will give me a blank disk - with no permission
help!Do you have access to another Mac? It would be helpful to try the external drive with another computer to make sure the problem isn't with your Mini (it probably isn't, just good to eliminate that as a variable). I don't know Dublin, but surely there's a Mac retailer somewhere that has a few demo machines out.
Alternately, you can create a new admin user on your Mini, log into that user, and try accessing the drive there. This would show you if it's a problem with your main account or specifically permissions.
You should also check your Finder prefs and make sure you have removable drives set to show up on the Desktop. Since you just did a clean install and this is the default (I think), this shouldn't be a problem, but it's worth checking.
If none of these steps yielded positive results, the next thing I would do is run Disk Warrior. This is arguably the best disk repair app for Mac OS X; it's definitely my favorite. Your external drive could have a corrupted directory or some other problems that Disk Utility isn't seeing/fixing for whatever reason.
If none of this works, reformatting the disk is the last step. As long as the drive itself isn't physically damaged, and the problem isn't something on the Mini itself, reformatting should fix the problem completely. And since it sounds like you have your data backed up, maybe you should just skip to this step and be done with it.
Good luck. -
PLEASE HELP ME. I transferred my music library onto an external hard drive as it contains about 30 000 songs. I got a second hard drive as extra security and loaded the songs onto that as well. Both hard drives now contain my music library however when I click onto my i tunes on my mac I am only seeing the music that I have downloaded from the i tunes store that has been kept in the cloud. How do I get my music from the hard drive to be recognized on my mac? Please, please, please help!!!
To import music into your iTunes library on the computer go to iTunes>Help>iTunes Help>Add items to iTunes and follow the instructions
Delete the "songs" that do not play in your iTunes library and reimport them. -

I backed up files onto an external hard rive form my old PC. Now I want to retrieve the files to put on my mac but it is telling me to format it to Mac. How can I do this without erasing all of the data on my hard drive?
Your drive was used with a PC and formatted NTFS which is proprietary Microsoft format.
You need to install a third party program that will read the NTFS format.
There is various software from PARAGON, Tuxera and NTFS-3G
When you get the data off and have verified it to be good, reformat the drive either HFS+ for Mac use only, or for Mac and PC use then MSDOS (FAT32) for under 4GB files (best) or exFAT (for larger than 4GB files) is proprietary and Microsoft is appling for a patent, which would likely mean OS X won't be allowed to read it anymore without a licensing fee and you'l have to pay another third party software company to read the format, just like NTFS is.
The less you have to rely upon third party sources to read your drives the better, this way if you have a issue and need to read the drive on another machine you don't need the software, and a internet connection and a credit card and...and...and... -

If time machine puts all of my photos onto my external hard drive using time machine, can I then delete the photos from my computer but view them again from the external hard drive? Basically, can I free up space on my mac but not lose years of photos?
To add to Niel's comment bear in mind that if you have a backup copy on an external HD and later delete the orignals on your Mac HD you will then only have one copy - so no backup.
If the pictures are precious you should have at least two copies, and ideally another copy kept off site, -
I want to create a back up of my iPhoto library on an external hard (not the time machine backup). I've searched the iPhoto help, but unfortunately it does not tell me 'how' to create this additional backup of my library. Thanks
Most Simple Back Up:
Drag the iPhoto Library from your Pictures Folder to another Disk. This will make a copy on that disk.
Slightly more complex: Use an app that will do incremental back ups. This is a very good way to work. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically.
Example of such apps: Chronosync - but there are many others. Search on MacUpdate or the App Store -

I have my iTunes music folder stored on an external hard drive. I recently purchases a new Mac. After attaching the external hard drive, all songs imported without a problem except my playlists. Any clue about where they are or how to revive them for use on my new Mac?
Thanks!Rysz wrote:
To retain your playlists, artwork, play counts, etc, you need to move the entire iTunes folder, not just the music files..
Correct.
After that just select the new folder location in iTunes> Advanced settings.
Incorrect.
Hold Option and launch iTunes.
Select Choose library and select the iTunes folder.
This will read the iTunes library.itl file in this folder and the library as it was previously will be opened. -
