External Hard Drive won't play music after upgrade

I have all my music and iTunes on an external hard drive and it worked great unitl I upgraded to iTunes 10. Now it says it can't play the music because it is from an earlier version of iTunes. PLEASE HELP!!

Same here, but I can play everything that I own, but can't play rentals. I think that is the reason because it is on an external hard drive. iTunes is to big for my MBP hard drive. Not sure what the problem is.

External hard drive won't mount, even after disk repair.

My Toshiba external hard drive won't mount on my MacBook Pro 10.8.5. I can see it in my disk repair, and when I repair, "the partition map appears to be ok." But I can't access the icon to be able to open the hard drive contents on my desktop. Help!

External hard drive won't shut down after switch from OS10.5 to OS10.4.11

i recently chanded my OS from 10.5 to 10.4.11 (as a programme i want to use is not compatible with leopard), but since i have done this my external hard-drive won't shut down automatically when i shut down my mac. i have to switch it off at the plug instead.
can anyone suggest how i can get it to do this again?
i'm a little concerned that i'm damaging the external drive by turning it off manually all the time..
thanks

Some hard drives shut off with shutdown, some don't. Sometimes hard drives that did shut off with one system will not do the same with a different system. My hard drives which did shut off, prior to 10.5 now stay on.
This is not really a problem as all hard drives spin down after 10- 20 minutes when not in use, whether your computer is on or off. Leaving the drive on is fine, shutting it off manually is fine.

Do you also connect the external USB drive to the AC power as well while you use it ?
Sometimes USB external drive problems are resolved simply by plugging them into the mains power and trying again.

External Hard Drive Won't Mount- Need to recover files

Hello Everyone,
I am hoping that one of you fine mac experts may be able to assist ~
Problem: External Seagate FreeAgent Desktop USB external hard drive
won't mount on desktop=ie: no access to my important files.. Please Help!
Details:
External seagate freeagent 500 GB Desktop USB HD ( only 2 months old)
(using for document / file backup-not as a startup disc)
on my Mac G3 350 MZ Blue & White Tower /768 ram/ running OSX 10.1.5 & OS9.2~
~
Problem: Started using the external 500 GB HD 2 months ago -with no problems-until this morning. Tried to double click to open it to access files
and got the "beach ball of death" and needed to restart.
My trusty G3 started up fine, however, the external HD was now
not showing up on the desktop as normal. I troubleshooted -by restarting,
trying different a/c plugs/ different USB ports , ran disk utility..called
seagate -not much help . Seagate said to try the HD on another mac-which I did-
a G5 tower- same problem.
~
The External hard drive will show up in disk utility, but is grayed out.
and when click "mount" same two messages keep showing:
message 1: "a disk attempting to mount as unknown has failed verification or has failed to
mount.please use disk utility to check the disk"
~
message 2- when unplugging and repluggin the usb in-and upon
restart:" you have inserted a disk containg no volumes that mac osx
can read to use unreadable volumes,click initialize to continue with the disk inserted ,click continue"
~
( I really need access to these files- and do not want to re-initialize the HD!!)
I ran Disk Utility /first aid "verify & repair , the following info came up:
Repairing disk "main backup 2007 ".
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid key length ( <<<IN RED )
Repair completed. "
~~
Though it said the repair was completed, the "invalid key length" issue
still comes up when re-running disk utility...Hard drive would still not
mount on desktop-even after restarting .
~~~~~
If there is a mac genius out there that can help?- it would be greatly
appreciated. I have tried to call seagate several times in the last several hours-
1st time-they disconnected me after being on hold 10 minutes-2nd call
I was put on hold for 40 minutes ..Finally spoke to someone ( they are not mac users or mac experts!)and he said I would need to send it to Seagate's Data Recovery-... for a fee of course!
~~~
At this point, I am hoping to just get the files and photos off
the hard drive- I heard about Disk Warrior-should I use that and if so
what version?
Thank you very much!

Will zapping the PRAM be of any use in getting the external to mount on the desktop?
Your external Hard drive is already recognized. But it cannot be mounted on the desktop due to its directory damage. You can certainly Zap the PRAM, and it will not hurt anything, but I am skeptical that it will change the situation.
Do you think the Disk Warrior 4.0 cd will even work on my G3 350MHZ running Mac OS 10.1.5?
If you boot from the CD and run it from the CD, absolutely yes. If you attempt to INSTALL it from a download or a CD, probably not.
Have you ever used Disc Warrior and is using it complicated?
I own and use Disk Warrior. You select the drive to be rebuilt, it builds a proposed new directory from the information and file fragments available.
When complete, it will provide a list of problems encountered, tell you what files have been placed in the "Rescued Items" folder, and allow you too look at your drive using the proposed new directory. Your only decision is whether the new directory seems to be an improvement over the old \[in your case, hopelessly corrupted] directory. You then tell it whether to replace the old directory with the proposed new directory, or to abandon its work and leave your Hard Drive unchanged.
Is there a good chance that the ext HD will still have my files on it- or do you think from what I've described that they are gone ?
From what you have described, your files are very likely to still be there. Sometimes in a situation like this, a handful of files cannot be recovered.
My other thought was to take the external HD there and have them try to recover the files.
Make sure you completely understand the costs involved. File recovery using a service like DriveSavers can run into many hundreds of dollars. They are prepared to disassemble your drive in a clean room and replace controller boards and read/write heads to achieve success. Your drive has serious, but not fatal, Directory damage. The Hardware, and most of your files, are likely just fine.

External hard drive won't unmount for disk utility.

Im not sure if this is the right topic area but I have a white macbook and my external hard drive won't unmount. I want to erase it via disk utility but it keeps telling me other programs are using it.

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.

Can I use Time Capsule 1TB as an external hard drive tos tore my music library(but with cable connection,not WI-FI)

Can I use my Time Capsule 1TB as an external hard drive to store my music library but with a cable connection(Ethernet or USB) and not Wi-Fi.

Yes, with the following warnings.
1. A 1TB TC is a Gen3 or earlier and can die at a moments notice.. So backup is essential.
2. A Gen1 or 2 is slow.. even over ethernet they were processor bound and so transfer speeds are not great.. a USB2 plugged into the computer will be faster. Gen3 is about 50% better as the processor was upgraded by 50% speed.
3. TC has no built in backup.. TM cannot backup network drives.
4. TC is designed to spin up slowly and spin down quickly.. you will have issues with itunes constantly losing the library.
5. You cannot use USB to the TC.. it is a network drive. If you want to use USB directly on the computer buy a USB drive.. but buy as fast a drive as your Mac supports.. Thunderbolt>USB3>FW800>USB2
USB3 is cheap and very good.. but the port is only from 2012 so check your Mac specs.
Thunderbolt whilst being super fantastic and around since 2011, has a bank account clearing price although there are Thunderbolt to esata converters.. for around $160. esata falls between usb3 and fw800.
FW800 from WD is no better than USB2 but other brands it can be twice the speed of usb2.
USB2 is the worst. But still faster than a TC.

How do you transfer iTunes to Windows 8 when you use an external hard drive to store you music/media files

I've tried a number of different search terms and yet can't quite seem to find an exact answer to my question.
I currently use a Windows 7 computer and have my songs for iTunes on an external hard drive. I would like to find some step by step instructions on how to transfer my library to a new Windows 8 computer and still utilize the external hard drive to store my music. What I find very confusing is I have similar folders for iTunes on both my computer and the external hard drive (ex. Album Artwork, iTunes Library Extras, Previous iTunes Libraries). I'm not sure which files to move over to the new computer to make for a smooth transition.
Thanks in advance for your help.
Paul

HT203167 Moved iTunes library from one computer to another using external hard drive. Cannot play many files. Says they are missing but locates them in an archive file but still won't play them. Are the files themselves part of the .itl files?

Moved iTunes library from old computer (PC Windows 7) to new (PC Window 8) using external hard drive. Library listing shows all music but can only play a fraction of it. On the ones it cannot play it asks to locate, then refers to an archived version (an .itl file), and still cannot play them. Do I just need to copy the archived .itl over, or is that not where the actual media are (do the actual media files even exist on the new computer?)? Any advice or information on this would be helpful.

*Also...is there any way I can filter out all the tracks with the ! so I can delete the unplaying copies as they're taking up room in my iTunes? I know how to find duplicates, but then I have to go and delete each one individually...*
*Thank you!*

Transferring music to an external hard drive while keeping play counts

Hello all.
I received a 250 GB external hard drive for my birthday yesterday as my internal one was getting very full. I decided that I would transfer my 3000+ songs on to it in hopes of clearing some room. Now, I know that once you move a file from its original destination (I did not have the "Copy to iTunes Music Folder" setting enabled) but I have consolidated my library and now everything is in that folder.
I've been having a lot of trouble getting the songs to actually be recognized from my external hard drive even though the whole iTunes folder had been copied there (I was too afraid to delete the original incase it didn't work). I have also went into the iTunes preferences and changed the location of the folder to where it is on my external hard drive, and it updates the library but when it is done nothing is different. When I look at the "info" for songs, they are still shown as on my internal drive.
How do I make iTunes see that my music is on my external drive and for it to start looking there instead of internally while keeping my play counts and playlists?

Hi,
here is the correct procedure for moving your music to an external drive - http://support.apple.com/kb/HT1364

External hard drives won't mount after upgrading to Tiger 10.4.9. Help!

Hi, I've just got the latest iMac. Very excited! I did all the software updates, connected my Western Digital extended hard drive so that I could copy some files over onto my new Mac. It was fine at first. Then when I wanted to open up the external hard drive icon on my desktop again and double clicked on it, everything disappeared from the screen for a few seconds, then reappeared but my external hard drive simply opened the window to my personal hard drive on the Mac. The WD links to my computer via Firewire. I then connected my USB external hard drive stick and it was the same story.
I used Disk Utility to test everything and everything was fine.
I then reinstalled Mac OSX 10.4.8 and plugged in my external hard drives. Everything worked perfectly. After copying over documents and a couple of programs, and downloading a few more programs, I ran my software updates again, upgrading the operating system to Tiger 10.4.9. I attached my external hard drive and it was the same problem all over again.
I the read up the online discussions and also chatted to an Apple dealer, and their advice was to download the Intel Combo and reinstall the operating system. I have just done this and my external hard drives will still not mount properly. Their icons appear on screen but double click them and everything disappears.
Please help. This is really frustrating as I have a backlog of work to do and I seem to be wasting hours on this. Not only that, this is a brand new machine which I rightly expect to work straight away.
I look forward to your response. Thank you in advance.

Hi, try to put your HDD in other Mac and look if appear the same, also you can try to repair permission.

Music from External Hard Drive suddenly not playing...

The other day I disconnected my external hard drive to use it elsewhere, plugged it back in later, then suddenly none of my songs located on it could be played on itunes...
Funny thing is that if I right click and go "show in windows explorer" it takes me to the correct directory on the external...however when I go to play the song the small speaker icon appears next to it, however without the "sound waves" that appear when a song is playing....
Can anyone help me out???
Thanks

If you have relocated the media folder to an external drive and then start iTunes with the drive disconnected iTunes will reset the media folder to the default location on the internal drive. It will also assume that all files on the drive are "not present". Correct the location of the iTunes Media folder, then close iTunes, wait a few moments and open it again. iTunes should now find your files.
