PC to Mac with external drive as main library

I recently switched from PC (Dell Inspiron) to Mac (MacBook) and am having some serious difficulties getting my iTunes to cooperate.
I used an external drive as my main iTunes library on my PC. I would like to continue doing this with my new Mac because my library is quite large. I know it is not as simple as pointing to the folder on the external HD from within the Mac. I have read all the posts out there and none of the address my issue specifically.
To reiterate, I currently am using an external HD with my PC that contains my iTunes library. I am now using my Macbook as my main computer and want to continue using the same external drive because my library is too large to import to the internal HD. How do I get the iTunes on my MacBook to read (point to?) the external drive where all of my media (music, podcasts, TV, Movies, Games, etc) reside without losing any information and/or files?
Please help...thanks!
Brian

I pretty much did the same thing (switched from PC to Mac) and had the same issue and this is how I set it:
go to preferences then click on the advanced tab, then on general
then for the folder just click 'change' and set it to be what your folder with all your music is on (on the external). I unchecked the 'copy files to itunes music folder...' as well (not sure this is needed, but didn't want to experiment it copying everything again)
then I went to File > Add to Library, selected the same folder and done. It will take a bit as it goes through the whole library. I guess after this you could go back to preferences and check that copy to itunes folder so any future additions get put on the external.
I hope that helps.

Change itunes from PC to Mac with external drive

Been using a Dell with itunes for my music system in mt home. I installed an additional 80G that i've maxed out with tunes. This is in addition to the 30G that came with the system. I have a Mini and just purchased a 500G Western digital external drive. I want to transfer all the music on the 80G (PC/Windows)to the 500G(which is not yet formatted)and set the Mini up as the music system. Could use some pointers on the best way to do this.
Many thanks

First, make sure that the hard drive is formatted for FAT32; then it can be used by either the PC or the Mac.
Then the easiest way will be to just drag the entire iTunes folder to the external hard drive (the one actually titled "iTunes", containing the iTunes Music folder and the iTunes library files). Then connect the drive to the Mac, hold down the Option key and launch iTunes. You'll get a dialog box offering to either create a new iTunes library or use an existing one. Choose the "use existing" option and select the iTunes folder on the external drive. Then just make sure the drive is connected and mounted on the Mac before you launch iTunes (otherwise it will reset back to the default location on the internal drive).
Hope this helps.

External drive for main library

I'm reading about external drives to find one to hold main Lightroom library. I want to be able to import and develop photos from either of 2 workstations: MacPro with 2 2.66GHz dual core Intel Xeon and iMac with 2.33 GHz Intel core 2 duo. I have other externals on each workstation for Library backups. And original nefs and dngs, master copy psds, and print ready tiifs are all burned to CDs or DVDs.
Drive wouldn't need to be bus powered, but I can't find any with a second power adapter available. Doesn't need to be smaller than a paperback. Don't know enough about Raid or SATA drives yet, except that some photographers use them for this purpose. Main concern for me is that editing speed be close to what it is now on the internal drives.
Will a Firewire 400 external at 72,000 rpm be close to same speed or is SATA faster and as reliable?
Thank you.

SATA is marginally faster. You have to determine where the bottlenecks are. For example, on my 1.8GHz Centrino notebook, running Lightroom, with my catalog database file on the notebook's drive, but the actual image files on a network hard drive (Gigabit network; 1000BaseT), it takes a second or two for a 12MB RAW (DNG) file to find its way from the network drive to my notebook, but many seconds for Lightroom to process it (for example, loading it into the Develop module, or performing the calculations for an export to local drive).
An export to local drive can take ten seconds per 15Megapixel image. That's about 1.5 seconds of IO time reading from the network drive, and about 1 second write time to the local drive. That means there are 7.5 seconds spent in reading the database file, applying corrections, rendering the image in its export format, and other associated calculations.
So I'm 25% IO bound, and 75% computationally bound (processor speed and RAM speed).
This being the case, even if I doubled my network drive's performance, I would only improve my overall performance by 12.5%. If I doubled my computational power, I would improve my total performance by 37.5%.
You may find that you are IO bound to a more significant degree. But even then, you're unlikely to notice an appreciable real world difference between Firewire400, USB2.0, and Gigabit networking. Yes, there are differences, but in the grand scheme of things, the difference between them in real world total throughput is not enough to make a huge difference to your Lightroom performance.

Moving iTunes from PC to MAC with external drive

Need some help moving my iTunes library from my Windows PC to my new MAC. The library is on my external USB drive. I did the consolidate option on my PC first and moved the USB drive to my MAC and changed prefs to point to my USB drive on my MAC. The library doesn't show up on my MAC? The library is 180GB.
Any suggestions?

How best to move user folder to a Mac Mini + external drive

I am streamlining my desktop computer setup. Whereas before I was using a PowerMac G5 as my primary desktop computer, I realize I am using my MacBook Pro more often, so in the interests of conserving space, I will be switching over to a Mac Mini connected to my AV system for hosting all my iTunes music, videos, media, photos, etc.
Here is where I need advice. My PowerMac has a lot more media on it than can fit on the internal hard drive of a Mac Mini. I have already secured a 1 TB external drive which will be permanently connected to the Mac Mini, but I am unsure as to how to best go about copying my data to it.
My initial thought was that I could move the iTunes music folder to the external drive using the library consolidation feature, and I could copy my iPhoto library to it, then point the respective applications to the new location. However, I want the external to act as my home folder where the OS looks for all my personal data, including movies, documents, etc.
I know there is a procedure for changing your home folder's location to an external drive, but because of the limited size of the Mac Mini's internal HD, I would like to use migration assistant when I first start using the Mac Mini. Should I hold off on moving the home folder until after I have migrated, or can it be done beforehand?
Anyone have any thoughts or ideas? Thanks!

Thanks for the procedure. It seems very easy, but I am wondering about the consequences depending on when I do it. For example, let's say I first copy my entire home folder to the 1 TB external drive, set up the PowerMac to use it as my home folder, then use migration assistant to import my user accounts, applications, and settings onto the Mac Mini. Will it try to extract the data from the external drive onto the Mac Mini's internal drive? There won't be enough room for everything.
As an alternative, I can move my iTunes library and iPhoto library onto the 1 TB external first, keeping the rest of my user data in its original location. Then it can fit on the Mac Mini, and I can do the migration, then move the home folder to the 1TB external once it's all up and running on the new computer.
Which will work best?
I had heard about people using a single drive as their home folder across multiple computers, but that is not the case for me. My MacBook Pro will become my primary computer, but I intend to keep it clear of media, whereas the MacMini will become my media server for my AV system in my living room. The 1 TB will be constantly connected to the Mac Mini, so there shouldnt be a problem with starting it up once the user folder location has been moved.

How do I install my LG Super Multi BLADE Mac compatible external drive without the install disc?

I can't find my install disc! How do I install my LG Super Multi BLADE Mac compatible external drive without the install disc?

You don't have installer discs with that model. What do you need to do? USB and Thunderbolt external drives do not require any special software. If you need to partition and format them, then use Disk Utility in your Utilities folder.

Serious problems after Mavericks installation with External Drive Lacie P9220.

Experiencing serious problems after Mavericks installation with External Drive Lacie P9220 1TB. Mac Finder totally locked!
I had to format the External hard drive with a Windows PC (fat32), then format again with my IMac (mac Journal.) and hopefully restored data from time machine backup.
So far so good but system looks unstable. Some software were not able to write on the hard drive.Some strange things happens. With Mountain Lion never had an even minor issue.
I read many discussion regarding problems with WD, just wondering if anyone had the same problems with Lacie and if there is any tip to solve the
problem.
Many thanks.
Marco

Thanks very much for your reply.
Unfortunately I couldn't find a solution because the article refers to whom have configured the drive with included software and drivers that came with the drive.
This is not my case, I never used any third party soft ...only OS X disk utility ...

Finder crashes with External Drive on Sleep Mode

I purchased my new iMac 21,5" less than a week ago, and I haven't had a problem with it except for one that it's been bugging me a lot.
I have a LaCie 1TB Quadra d2 external drive that I use to store footage (since it's HD, the filesize won't fit in my 500TB internal hard drive), but I noticed that sometimes when LaCie external drive enters in Sleep Mode, the Finder freezes and the only two ways around this, is to force reboot, because the Finder won't answer and won't open again, or unplugging the external drive without ejecting him first, which it's not safe for me to do, because I'm afraid of hurting the device, and the files in it are pretty important.
This happens almost everytime, especially after a long time on sleep mode. I usually leave Final Cut Pro transferring files all night (since it takes a long time) so I kinda need the sleep mode, but when I wake up, Finder and Final Cut Pro won't answer.
I updated to Snow Leopard 10.6.8 on day one. Is there a way to fix this? Is it normal? I read somewhere that some users were having trouble with external drives on Sleep Mode, but I can't seem to find any further information about this problem.
Thanks!

I've got a MacBook Pro 13.3" that's a little over a month old, with a LaCie 1TB LaCie d2 Quadra with USB 3.0, #301542U and I'm suffering the same problems and a few others with it. I've got a partition on it set up as my Time Machine backup drive. I've turned off the Put the hard disk(s) to sleep when possible in the Energy Saver preferences but I'm still having the sleep problem with it. According to the LaCie Manual:
By default, your drive will enter Eco Mode after 30 minutes of inactivity in order to conserve energy. To exit Eco Mode, simply access data on the drive and the disk will automatically restart. You can manage this feature using LaCie Desktop Manager. Click the Eco tab.
The LaCie Desktop Manager (in my case) only takes me to the Energy Saver Preferences in OS X to adjust the time there. Turning off Put the hard disk(s) to sleep when possible doesn't seem to make any difference, the drive still goes to sleep after 30 minutes. However, after 15 minutes the drive seems to wake back up, but then during the next 15 minutes goes comatose (no power light). Sometimes it will go through multiples of these sleep wake cycles without going into a coma, but eventually it does go into a coma. This happens in between hourly Time Machine backups.
After locking up Finder, Disk Utility and Time Machine multiple times trying to access the drive in this state I figured out that I could cycle the power switch to regain use of it (with a Finder warning of course) but this will only lead to file corruption eventually and I shouldn't have to resort to this. I've also dismounted it, expecting it to turn off and instead it goes into an extended spin down cycle (rapidly flashing light) and never turns off (or goes to sleep or what ever it's supposed to do) and once again requires turning the power switch off.
This is just too unpredictible and unrelable for me and as soon as I get the opportunity to do a 7 pass erase I'll be returning to the place of purchase. Based on the reviews of other external hard drives a drive from another company doesn't look to be much better of a prospect so I'm not sure what I'm going to do.

IMac won't boot with external drives attached

I am using iMac 27" Late 2013 model upgraded to mavericks 10.9.4. Two external drives are always attached with it, one is segate 3.5" 2TB USB 3.0 drive and another one is 2.5" usb 2.0 drive.
when i start my imac with external drives attached it won't boot up. Stuck at plain white screen after a startup chime, not even any apple logo or any progress circle appears. And i have to detach all of my drives to make it boot.
This problem arises after upgrading to mavericks. Already tried resetting PRAM, SMC and checked Startup disk and verify disk with disk utility.

Raja,
Do a SMC reset perhaps even a couple of times and see if that helps. Also in System Preferences + Startup Disk make sure the internal HD is selected.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

ITunes Match songs on library with external drive

Hi,
I have all my music on an external drive (and my library files on the internal drive). I activated iTunes Match so I can listen to my music when the drive is not present. iTunes Match activated succefully and I see all my music on my iPhone. But when I launch iTunes without the external drive present and I try to play a song it just prompts me to locate the missing file and it doesn't give me the option to play it from the cloud. Is this fuctionality not supported or am I doing something wrong? Thank you in advance.

As Jim says not all DRM-restricted tracks will be eligible to be "matched." If you bought them from the iTunes Store then they will still be "purchased" and the only way the DRM can be removed is to burn them to an Audio CD and import them to the iTunes library again. However, this does not guarantee they will then be "matched" either.
To see the iCloud Status of any tracks switch to Song view in iTunes and pull down View > View Options and select "iCloud Status" then close the small window. The tracks that are still DRM-restricted will most likely be either "purchased" or "uploaded."

ITunes are not seeing my external drive as the library

Hi, I'm struggling to get music on my iPhone.
All our music is stored on an external hard drive that we use with our iPods. My wife and I recently got iPhones and we're trying to put some music on them.
iTunes is setup to get the music from the hard drive but for some reason I can not access it any more. My problem is that iTunes are not seeing my external drive as the library.
Here's how I've set my iTunes up:
Edit - Preferences - Advance
iTunes media folder location: J:\Lacie_iTunes (that's where the music is stored)
Now this worked perfect with our iPods but for some reason iTunes is not seeing the music anymore.
In iTunes, if I click on Library and then Music all I get is a screen to either download music (with tutorials) or import CD's (with tutorials).
I'm using iTunes 9 and Windows 7, the iTunes version on my wife's laptop is an older version but I do not think that that is the problem.
Any advice would be MUCH appreciated!

Setting the iTunes Media folder in preferences only moves the content to the external drive. The library database files will still be at the default location of ...\My Documents\My Music\iTunes. When you move the portable drive from one machine to the other you'll have access to the content, but not the database hence you get an empty library and the prompt to add some content.
See this recent post for pointers on how to rearrange the database & media folders so that everything is truly portable. I don't have time just now to rewrite the instructions for your specific drive & folder names but if it's not clear I'll pop by later and write them out again.

Issues with external drive on Mac Mini / Lion

I'm using an external SATA drive in a Newer Technologies Voyager dock (which I like to call the "toaster") with a brand new Mac Mini i5 2.3G via FW800.
The drive was formatted using Disk Utility on a G4 running Tiger (10.4.11)
With the drive mounted, the Mini's performance seems to slow down, and it randomly dismounts the drive, with the usual warning, "you disconnected your drive without dismounting it first, bla bla...)
I think I remember when Leopard was new, there was a firmware issue that had to be dealt with, and when moving drives from OS 9 to X and back to 9, I lost access to the data on the drive.
I'm also aware of the partitioning scheme difference when formatting drives for use on the Intel machines.
Could either of the above have anything to do with the problem I'm having here?

I'm not an expert in this, but as far as I know, GUID only comes into play if you want to boot from it, but...... you never know, it could - here is an excerpt from Disk Utility:
If you’ll be using the disk only with Mac computers, choose GUID Partition Table.
Another thought is: how old is that drive? All hard drives fail sooner or later - have you tried to check it with Disk Utility or something like Disk Warrior?

Problems with transfer of movies from Mac to external drive.

I want to transfer movies from my iTunes library to an external drive, in order to back them up for future use. I keep getting the message:
"The operation can’t be completed because the item “Cabaret.m4v” is in use."
How do I solve this problem?
Kerneels

Have you restarted your computer?
By the way, "transferring" is not the same as "backing up". Backing up means more than one copy on separate drives.

Format & install Leopard from a second Mac, or external drive?

hi there,
i'm trying to format my macbook, but unfortunately my dvd drive won't read my installation disc. after looking through the forums, it appears that i can put the installation disc on an external drive, and do the formatting from there. unfortunately, though i have a drive to clone my computer onto, i don't have an additional drive to dedicate to this re-formatting. however, my roommate believes there's some way he can use his mac to to format mine. is this possible, and if so, how? is one method (external drive vs. second mac) preferable to another?
thank you for your help.

With two Macs that support FireWire you can do what you describe, but you must have a MacBook with a FireWire port. You will use Target Disk Mode.
With both computers turned off connect a FireWire cable between them (400 or 800 is fine.) Boot your MacBook into TDM. After the TDM screen appears insert the OS X Installer Disc into the optical drive of the other computer then start it normally and after the chime press and hold down the "C" key to force the computer to boot from the DVD. After the installer loads select your language and click on the Continue button. As soon as the menubar appears select Disk Utility from the Utilities menu. You can then use the Restore option of Disk Utility to clone your MacBook's drive to a FireWire drive:
How to Clone Using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
4. Click on the Restore tab in the DU main window.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the external FireWire drive.
Source means the drive in your MacBook.
You may wish to test this clone to be sure it will boot a computer successfully.
Once you have cloned your MacBook's drive use Disk Utility to erase the drive so you can reinstall OS X.
