Cloning os hard drive to external drive

Would like to create a carbon copy of my os hard drive to an newly purchased hd for "safe keeping" in the event the os drive is corrupted or fails.
Existing os hard drive is a 200gb hard drive and is functioning as i would like it to at this point. New drive is a 320gb unformated that i intend to copy to externally. I have carbon copy cloner and have used it.
First of all what is recommended way to do this? Use disk utility or ccc? Anything considerations in regards to the larger drive size? Will I have permission issues when booting the 320gb drive once it is cloned?
What is the procedure to boot the external drive to check the clone?

Prep your new drive:
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. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. 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 Options 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.
To clone:
Clone using Restore Option of Disk Utility
1. Select the destination volume from the left side list.
2. Click on the Restore tab in the DU main window.
3.Check the box labeled Erase destination.
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.
Upon completion quit DU. Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon of the external drive and click on the downward pointing arrow button. If all is well the computer should startup from the external drive. To return to your internal drive just restart the computer.
If you plan to use the external drive for more than just the clone then you should partition it during the preparation phase into two volumes. The first volume should be the same size as your internal drive - 200 GBs. The remainder will make up the second volume.

I can't import any photos. 'Could not copy to requested location' is the given but i have tried importing to both hard drive and external drive.

i can't import any photos. 'Could not copy to requested location' is the given but i have tried importing to both hard drive and external drive. Help please ?

Most likely, the "requested location" where you are trying to copy files to does not have WRITE permission, and so you need to change the permissions.

HT201250 How to retrieve external drive backups from time machine on hard drive without external drive connected

I am keeping my work files on an external drive which are backed up using Time Machine onto my computer's hard drive. I set it up this way so I can take my actual work drive with me if I need it. However, I just noticed that I can't see any of those files in time machine if the drive itself isn't plugged in, which makes this method useless. Is there any way to get to those, or do I need to reconfigure my backup system? I always thought if something happened to my hard drive I'd have a backup, but that won't work if I can't get to the files.

See Pondini's TM FAQs, for starters.

Moving iTunes music folder from hard drive to external drive

I see a couple of topics related to iTunes folder locations and losing track of where the file are. What's the right way to migrate from having the iTunes music files on my hard drive (C:) to using an external drive...without having to re-map everything manually? I'm running out of space on the C: drive!

There's actually hundreds of those topics. It gets asked daily.
Did you still have a specific question after reading several of them?
Here is a very thorough and wordy article on it

Which is faster for music production? internal hard drive or external drive

hey there. simple question. i'm looking to run music poductin software on an apple mac - would sound files be retrieved faster from a new mac book pro internal hard drive or an external drive? (am thinking one of those lacie orange rugged things that spin at 7200 rpm)
and if the sound files would play better coming form the internal hard drive, would it compromise processor speed for running soft synths / effects units etc etc?
please note am not talking about my current mac book, but a new mac book pro
chanx in advance - horton ;o)

For what it is worth here is my tuppence worth on the subject, horton. (and a warm welcome to the forums , by the way!)
One of the major reasons why many sound professionals (and others worried about speed) use fast external FW800 or (when possible) eSata drives for their work, rather than the internal drive of an MBP or the like, is that the internal boot drive is already carrying the OS and a bunch of apps on its fast, outer sectors. It is usually doing a fair bit of work keeping things running, too. An external FW 800 drive can be kept unencumbered of such things.
On top of this the 2.5" drives in notebooks are slower at the best of times than 3.5" drives. If you want real speed, my suggestion would be that you keep the internal drive for your OS and Apps as much as possible, and get a fast 7200 rpm 3.5" FW800 external with its own power supply for your sound files (assuming you will have access to mains power).
If you use the internal for this sort of purpose too, you are going to find that the internal fills up fast, that it soon develops free space fragmentation issues, and that it gradually slows to the speed of mollasses!

Tx1000 hard disk as external drive

After my tx1000 POT (piece of trash) burned out like everyone elses, I removed the hard disk and connected it as a USB drive through a standard external drive box. It powers up, spins, and is recognized as both as USB device and a disk drive by my new (not HP) computer, which is running XP and not Vista like the HP was. However, under Properties, I cannot seem to get the Volume to populate, receiving only the messages of "not readable" and partition style "not applicable", with the drive read as 0 MB. The driver is updated and listed as functioning properly. What next? I cannot fathom walking into an HP service center with my tail between my legs to pay them to help me with this, but I do need to access my old hard disk.

Is this a SATA disk? You may need the intel driver installed on your XP computer, XP by default, doesn't support SATA fully. Goto www.intel.com and look for SATA driver download for XP.

How to sync ipod when hard drive and external drive used for music?

The Ipod can hold all of my music. My laptop has some current music, the external drive has old music albums. How do I set up the music library / itunes library to sync with the ipod and not erase the music from the external drive when it is not connected.
I am used to adding mp3s to player, and they stay there until deleted. Now I sync the Ipod, and if I don't keep the external drive attached, the Ipod loses the old music.
I have searched all discussion lines and do not quite understand the how to of multiple libraries versus other options.
Thanks.

Easiest way is to make sure your exHD is plugged in before opening iTunes and syncing your iPod.

Transfering Music Files From Internal Hard-drive to External Drive

Per the instructions in a Missing Manual Book, I copied my itunes music folder from my internal drive to my new, portable external drive. The files copied fine, but the book said all I needed to do to insure file recognition was to change the location in the itunes>preferences>advanced location, which I did. But the only way the files are recognized by itunes is to, song by song, direct itunes to the new file. Is this really the only way to have it recognize the files? Is there no automatic method? The book implies that all is needed is changing the preferences location.

I'd make sure that the 'Keep iTunes folder organised' setting is on. (Preferences>Advanced>general)
Failing that, make sure that the 'Copy files to iTunes music folder when adding to library' setting is also on.

Need more storage - larger internal drive, or external drive?

Good day...here's a little background before I head into my question.
I have a mid-2010 Macbook Pro with a 320 GB hard drive. I have an 2 GB WD External Hard drive...I've partitioned 500 GB that I use for my Time Machine backups and use the remaining 1.5 TB to store additional files, mainly music and video files. I rarely keep it plugged in to my MBP....I'll plug it in to do the odd Time Machine backup every couple of weeks, but that's about it. I like taking the MBP to the living room to use and the idea of having to plug and unplug an external hard drive several times a day is something I've decided not to do. Additionally, I access most of my photos/music/video through my Apple TV to play them on my TV/receiver. I also have no need to use the cloud as I don't require access to my media files when I'm out of the house.
My internal hard drive has been filling up over the last year and as it has, I've been dumping video files to my external hard drive. If I need them again, I'll simply transfer the odd one back to my MBP and add it back to the Itunes library. However, even with the odd purging, my internal drive is now filling up, mainly due to photos and videos of the little kids. The time has come, I need to do something.
I know that I have the option to store my Itunes library on an external drive (and this would quickly fix my storage issue as about half the 320 GB of space is my Itunes library), but I've been hesitate to do so. I do have an Airport Extreme Base Station downstairs and a PC Desktop as well. In reviewing these forums, I understand that I can transfer my Itunes library to my external hard drive, connect it right to the AEBS and access my Itunes files on my MBP from there. However, as I buy new music/videos from Itunes or add other media files to my Itunes on my MBP, would they automatically transfer to the Itunes library on my External, or would I have to add them each time? Is it still pretty seamless to transition to having my itunes library on an external hard drive without a lengthy list of things that you have to "put up with"?
In an effort to resist too much change, I've been thinking about simply replacing my 320 GB internal drive with a 1 TB internal drive so that I can keep things pretty much as they are...keep the Itunes library on my MBP and continue using the 2 TB external for backups and some additional storage space.
So, with that, I'm curious to hear any feedback on how to approach this...am I complicating things, are there any suggestions on how I could be organizing things way better? And finally, is your advice to increase the internal hard drive, or should I quit overthinking this and just move the ituens library to an external hard drive?
Thanks!

large external HD
A computer should never be considered a data storage device, only a data creation/ sending/ manipulation device.
All mega-storage should be a "grab and dash" item to store in a fire vault etc. Easily unhooked from a main computer capable of lightning strike, failure, easy erasure, etc.
And never ever rely on one backup ever. Recipe for disaster.
There are currently only 3 HD manufacturers, WD, Seagate, and Hitachi/Toshiba (recently acquired by WD).
No such thing as a "windows" Hard Drive either, .....only a Win formatted HD. A HD is a HD ... whatever it says or is formatted in when you buy it,... you can format it for Mac OSX extended journaled.
All personal conjecture aside, Hitachi/Toshiba are the best 2.5" HD, same used by Apple inside the Macbook Pro
..... also those running literally 1000s of HD in server farms agree on this.
That being said, WD are not recommended as an internal HD for a Mac.
Most reliable 3.5" class HD are Seagate
The LaCie drives carried in the Apple stores contain 3.5" Seagate HD
Most reliable 2.5" class HD are HItachi/Toshiba (same as used by Apple in the macbook Pro).
MUCH empirical data (and my own as well) says that Western Digital are the worst
WD has some compatibility issues with Mac.
Best bang for the buck in external 2.5" HD, is the Toshiba Canvio Basics HDTB120XK3CA 2 Terabytes 2.5" External Hard Drive
I have 4 of these tiny 2TB drives, ....theyre highly rated, and phenomenal
Currently theyre $120
http://www.amazon.com/Toshiba-Canvio-Basics-Portable-HDTB120XK3CA/dp/B00ARJD56K
People running server farms and see 1000s of HD, and failures will all tell you the same, in 3.5" class, get a Seagate, and DONT get a WD.
7 out of 10 HD failures have NOTHING to do with the HD.......if a HD fails (and they all fail) , its usually first 3 months or less
7 out of those 10 failures AFTER 3 months is NOT a bad HD, but a cheap/junk SATA connector and circuitry which connects the external HD to your computer.
Seagate large BACKUP HD 3.5" had gotten, for a while a bad reputation, but it had nothing to do with the HD, rather the cheap SATA connector interface that it was plugged into in the external casing.

HT201250 Can time machine back up external drives to external drives?

I was wondering if I can use Time Machine to back up external drives. I know it backs up just my Mac, but need to know if
it will back up an external drive to an external drive.

Open your Time Machine drive. Open the Backups.backupdb folder therein. Open the Computer Name (e.g., Adam Smith's iMac) folder. Open any folder there whose name contains a date later than when you attached your (other) external drive. You should see a list of folders representing the drives that are being backed-up. One is typically Macintosh HD, your internal hard drive. There should be one for your other external drive.

Transfer Image files from Mac Drive to external drive

I have written a Bug Report aboiut this problem.

Here is most important problem statement:
Photoshop CS 6 Beta BUG REPORT
Juan Zumbado – [email protected]
DESCRITPION
I was trying to transfer some files from the Desktop in my computer to an external USB drive.
RESULTS
After starting to transfer the files, the external hard drive I got the following panels:
The external hard drive was unmounted and disappeared from the Desptop., and the Disk Utility could not find the drive. The drive external power was also turned off. I had to re-power the external drive to mount it, and rebooted my computer.
This was the only way to have the external drive to be seen by the Disk Utility. The external drive is a Calvary CADA-SA2 (RAID1).
EXPECTED RESULTS
The second panel was expected when the hard drive was disconnected.
This application of the forum now does not let me to past item. I does not let me import anything from my computer. It sucks.
The compuyter i'm using is a Mac Pro with OS X 10.7.3. Similar problem occured with a Mac Book Pro laptop, using the same OS X.
I have several pages that include the SYSTEM INFO requested. That I can send you if you send me your email address. I can also then add my pdf file thatalso includes CRASH LOG, although I don't think is applicable.

Time capsule drive and external drive won't wake up

I have a time capsule purchased in August (2TB) and a 2 TB WD MyBook external drive plugged into the usb slot on the time capsule. Given my computer is a laptop, it is nice to be able to put the external drive somewhere where it doesn't have to be plugged and unplugged with laptop use. The WD external drive houses my itunes library and is pretty sensitive and loses data whenever not powered down cleanly.
The problem:
Time Capsule drive and WD drive seem to go away and not allow me to access them no matter what I try. The only way to get them responding is to pull the power plug on the time capsule and power back on. This needs to occur each time I want to access either drive. When attempting to connect via finder I get connection failed errors.
I have no connectivity problems with airport. Access to network is fine, so I know the TC is not totally dead, just the part that lets me access the hard drives. It is interesting that time machine appears to be able to access the drive on the tc without problem but I'm not sure how confident I am that this is true just because it is telling me so.
Any suggestions? anyone else seeing this?

I am having this issue as well.
The behavior seems to be that the drives are available after a reboot and for some time afterwards. Then at some indeterminate time, the drives become unavailable. The Time Machine backups stop with a "Backup Delayed" message and I have to go to the Time Capsule and reboot it by removing the power and re-inserting it.
When the drives are unavailable, the wireless router functions are still active since I use this router as my gateway to the internet.

Unable to copy file from local drive to external drive

I'm attempting to copy a 7gb file from my local drive on my iMac to an external firewire drive. Whenever I try to do this I get the following message: Sorry, the operation could not be completed because an unexpected error occurred.
I've rebooted, checked permissions on local and external drive. I'm the only person that uses this iMac. It only has one profile on it. Any suggestions?

Hello Sikwidityo
If that External HD is formatted MS-DOS FAT32, then there is a 4GB file size limit that the iMac's can write to it.
See > http://www.macworld.com/article/51972/2006/07/ww_drives.html
In order to copy large files to it you from your Intel iMac's, you will need to set the Partition Map Scheme to GUID Partition Table and Format it Mac OS Extended (Journaled)
See > http://www.kenstone.net/fcphomepage/partitioningtiger.html
Keep in mind that repartitioning and reformatting will erase the current data on the External drive. So if you do, you'll need to copy it's contents to one of your iMac's and then back when your done.

G Drive mini External Drive

Hi,
I just bought my first external drive... a G drive mini portable and it seems to work fine.
I just had a question about noise. Is it normal for these ext drives to make noises all the time. It seems to constantly be making small static-like noises, sometimes more , sometimes less.
Thanks alot.

If there isn't a fan in the enclosure it shouldn't make much noise. Is it a 7200rpm or 5400rpm drive? The 7200s due make a little more noise.
I would contact g-tech support about your concerns.

No success in duplicating internal drive to external drive

Just added a new LaCie Quadra 500GB drive to my system and, using the OEM version of Retrospect Express I 'duplicated' (a Retrospect terminolgy) my Mac's internal 150GB volume to my external 500GB drive. After many hours, Retrospect indicated that it couldn't read 3 files and commended 'comparing' the files copied over the the originals. Eventually it stopped altogether with the blue 'worm' still indicating activity and with 58 files remaining to be copied and 593239 copied. The log listed 127 execution errors. After waiting 18 hours with no change to the 'worm' I quit Retrospect and tried a restart holding down the option key. Both external drives showed up with a 'X' and so the restart defaulted to the system on the internal drive. Where did I go wrong and how do I now set up my 500GB drive to be bootable?

You can use the freeware CarbonCopy Cloner @ http://www.bombich.com/software/ccc.html , or the freeware SuperDuper @ http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html , or the freeware IBackup @ http://www.grapefruit.ch/iBackup/index.html , or the Restore function of Disk Utility included in OS X.
 Cheers, Tom
