Why are external hard drives and similar continually self-ejecting under Yosemite?
When are Apple going to sort out the problem of external hard disk drives and other similar devices continually self-ejecting under Yosemite. This is a problem I have had ever since I upgraded my 21.5" iMac from Mavericks to Yosemite last year, and I when I upgraded to a 27" iMac last November with Yosemite pre-installed the same issue occurs. I cannot even update my TomTom SatNav because it keeps ejecting while the update is trying to process. I cannot use a WD external drive for backup purposes, and even memory sticks eject. This problem has only started with Yosemite and I do not believe I am the only one experiencing it as it has been aired on the communities website previously. I wish Apple would tackle this problem and issue a Yosemite update that resolves the issue. My present Yosemite version no.is 10.10.3.
Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

I will like to do this after installing itunes 11 on my pc for the first time. I am using windows 7. HP computer intel Dual Core. Thanks for any help!
Hey idw3,
Welcome to Apple Support Communities, and thanks for the question. Follow the instructions on this article to move your iTunes Media folder to an external hard drive:

I copied my iPhoto library to an external hard drive and the event windows show up black.
The photos are still there once I click on an event but they don't show in the window.
My next step is to delete the iPhoto library from the internal memory to free some memmory space but I don't want to do this until I see that the library works fine on the external hard drive.
How do I fix that?Hold down the "option" + "command" keys and launch iPhoto.
Select the "Rebuild Thumbnails" choice. -
I have been transfering photos and movies to an external hard drive and when I try and secure trash contents off my computor i get the message it will not continue In utilities the message is: SUID file syst/library/coreS has been modified and will not be repaired. Hence I cannot free up space on my computor. What can i do?
Do not worry. It is probably a permission you should ignore, but you should check that the permission appears in this site > http://support.apple.com/kb/TS1448?viewlocale=en_US&locale=en_US

I am having a very hard time. First I finally got all of my music back into iTunes and then moved them all to my external hard drive. I set up iTunes to automatically put and get music from the external hard drive and whenever I open the drive al of the music is there. Now, I bought a new computer and went ahead and got iTunes all set up then tried to add folder to import from the external hard drive but all the music folders are empty! They show the names of the artists and the albums but there is nothing inside. Please help!!
If you've just moved the drive between systems then see Repair security permissions for iTunes for Windows just in case that reveals the missing files. Apply to a single album folder first as a test. Otherwise, if you've not done too much with the drive since things went missing, an undelete tool might recover the lost media. FreeRecover looks promising... Select the drive, use the options to get file paths and check file integrity, then, presumably, you can restore anything that has been deleted that looks recoverable. Backup to another drive when you're done.

I have recently updated my OS from Leopard to Snow Leopard but now my external hard drive and even my iPhone are not recognized by my Macbook Pro! Anyone have a suggestion??
Zap the PRAM and Reset the SMC, then try again. If the problem remains, update to 10.6.8 and repeat.

I bought a GoFlex desktop external hard drive and when I attached to my old mac and transfered all my files they are all in asian text? It took all weekend to transfer and when I attached it to my new mini all the transfered files are in asian ... what can I do to change them into English?
What kind of files are these?
Are the Filenames in asian also?
Can you paste some of the asian here so we can have a better guess at what's going on? -
Why will Photoshop CS4 not open after loading to new iMac from an external hard drive and I get this message: Licensing for this product has stopped working:error code: 150:30
A Photoshop installation is tied to the machine it was installed on. Moving it to or from a hard drive breaks the licensing.
The answer is easy: Reinstall CS4 from your disc. and apply all updates.

I have just downloaded iPhoto from the app store. The photo library from my old laptop was backed up on an external hard drive and I retrieved the photos from there. Now when I open the photos on my new Mac Book Pro, they are small - am I missing something?
I am using 10.8.2 Mountain Lion btwI dragged the Photo library icon from the backup drive on to iPhoto on the laptop
That means you imported one Library to another.
Never import one Library to another. Every version and thumbnail is imported like a distinct photo, you lose all your Albums, Keywords etc., the link between Original and Previews is destroyed, the non-destructive editing feature is ruined and so on. In summary: it's mess.
So the reason you're seeing small photos is because you're seeing the iPhoto thumbnails from the back up library.
So, what to do?
Do you still have the back up? If so, trash this bunged up library and restore from the back up again. HOw to restore will depend entirely on how you made the back up, but no version of restoring includes importing the library.

I want to copy the songs that are in my ipod in to an external hard drive and not from the itunes folder in my computer (the reason being is that the songs in itunes folder are not to my taste. Please help?)
I have the orignal ipod 120gb
Many thanks.
AfzalBare in mind that Sync is only oneway, from PC to your device. Unless you have the same music on your PC, iTunes is going to wipe out what you have on your device if you are syncing to a new library.
You can only transfer Purchased music over to Itunes on your PC.

As for you own music, you may have to use a third party software. A good Free one is called Sharepod which you can download from Download.com here:

I didn't safely eject my external hard-drive as my imac was in sleep mode and I thought it was shut-down. Now I have turned up to uni and plugged my hard-drive into the uni computers (apple) and the word document I was working on last night (before my computer went to sleep mode, and it may still have been open, I cant remember) is gone.....
I have phoned home and got a family member to try and recover the file. They said they can see it when they open Word under recent documents, however its "ghost" and nothing happens when you click on it.
My question is, when I go home and plug my hard-drive back into my imac, will I be able to recover this word file? or have I lost it forever?I only saved it to my external hard-drive and saved it at the completion of working on it. However left the document open, went to dinner, and this morning pulled the hard-drive out, whilst the computer was asleep not shut-down and now the file doesn't appear.
I thought when I clicked save then it saved straight away, therefore anything i do after that point (ie a un safe ejection) shouldn't make a difference. Clearly, no matter if you saved the document, if you un-safely eject the hard-drive then the file is lost anyway? -
How to move huge HD video files between external hard drives and defrag ext drive?
I have huge high definition video files on a 2TB external hard drive (and its clone). The external hard drive is maxed out. I would like to move many of the video files to a new 3TB external hard drive (G-drive, and a clone) and leave a sub-group of video files (1+ TB) on the original external hard drive (and its clone).
I am copying files from original external drive ("ext drive A") to new external drive ("ext drive B") via Carbon Copy Cloner (selecting iMovie event by event that I want to transfer). Just a note: I do not know how to partition or make bootable drives, I see suggestions with these steps in them.
My questions:
1.) I assume this transfer of files will create extreme fragmentation on drive A. Should I reformat/re-initialize ext drive A after moving the files I want? If so, how best to do this? Do I use "Erase" within Disk Utilities? Do I need to do anything else before transfering files back onto ext drive A from its clone?
2.) Do I also need to defrag if I reformat ext drive A? Do I defrag instead of or in addition to reformating? If so, how to do this? I've read on these forums so many warnings and heard too many stories of this going awry. Which 3rd party software to use?
Thank you in advance for any suggestions, tips, advice. This whole process makes me SO nervous.Here is a very good writeup on de-fragging in the OS environment that I borrowed
From Klaus1:
Defragmentation in OS X:
http://support.apple.com/kb/HT1375 which states:
You probably won't need to optimize at all if you use Mac OS X. Here's why:
Hard disk capacity is generally much greater now than a few years ago. With more free space available, the file system doesn't need to fill up every "nook and cranny." Mac OS Extended formatting (HFS Plus) avoids reusing space from deleted files as much as possible, to avoid prematurely filling small areas of recently-freed space.
Mac OS X 10.2 and later includes delayed allocation for Mac OS X Extended-formatted volumes. This allows a number of small allocations to be combined into a single large allocation in one area of the disk.
Fragmentation was often caused by continually appending data to existing files, especially with resource forks. With faster hard drives and better caching, as well as the new application packaging format, many applications simply rewrite the entire file each time. Mac OS X 10.3 onwards can also automatically defragment such slow-growing files. This process is sometimes known as "Hot-File-Adaptive-Clustering."
Aggressive read-ahead and write-behind caching means that minor fragmentation has less effect on perceived system performance.
Whilst 'defragging' OS X is rarely necessary, Rod Hagen has produced this excellent analysis of the situation which is worth reading:
Most users, as long as they leave plenty of free space available , and don't work regularly in situations where very large files are written and rewritten, are unlikely to notice the effects of fragmentation on either their files or on the drives free space much.
As the drive fills the situations becomes progressively more significant, however.
Some people will tell you that "OSX defrags your files anyway". This is only partly true. It defrags files that are less than 20 MB in size. It doesn't defrag larger files and it doesn't defrag the free space on the drive. In fact the method it uses to defrag the smaller files actually increases the extent of free space fragmentation. Eventually, in fact, once the largest free space fragments are down to less than 20 MB (not uncommon on a drive that has , say only 10% free space left) it begins to give up trying to defrag altogether. Despite this, the system copes very well without defragging as long as you have plenty of room.
Again, this doesn't matter much when the drive is half empty or better, but it does when it gets fullish, and it does especially when it gets fullish if you are regularly dealing with large files , like video or serious audio stuff.
If you look through this discussion board you will see quite a few complaints from people who find that their drive gets "slow". Often you will see that say that "still have 10 or 20 gigs free" or the like. On modern large drives by this stage they are usually in fact down to the point where the internal defragmentation routines can no longer operate , where their drives are working like navvies to keep up with finding space for any larger files, together with room for "scratch files", virtual memory, directories etc etc etc. Such users are operating in a zone where they put a lot more stress on their drives as a result, often start complaining of increased "heat", etc etc. Most obviously, though, the computer slows down to a speed not much better than that of molasses. Eventually the directories and other related files may collapse altogether and they find themselves with a next to unrecoverable disk problems.
By this time, of course, defragging itself has already become just about impossible. The amount of work required to shift the data into contiguous blocks is immense, puts additional stress on the drive, takes forever, etc etc. The extent of fragmentation of free space at this stage can be simply staggering, and any large files you subsequently write are likely to be divided into many , many tens of thousands of fragments scattered across the drive. Not only this, but things like the "extents files", which record where all the bits are located, will begin to grow astronomically as a result, putting even more pressure on your already stressed drive, and increasing the risk of major failures.
Ultimately this adds up to a situation where you can identify maybe three "phases" of mac life when it comes to the need for defragmentation.
In the "first phase" (with your drive less than half full), it doesn't matter much at all - probably not enough to even make it worth doing.
In the "second phase" (between , say 50% free space and 20% free space remaining) it becomes progressively more useful, but , depending on the use you put your computer to you won't see much difference at the higher levels of free space unless you are serious video buff who needs to keep their drives operating as efficiently and fast as possible - chances are they will be using fast external drives over FW800 or eSata to compliment their internal HD anyway.
At the lower end though (when boot drives get down around the 20% mark on , say, a 250 or 500 Gig drive) I certainly begin to see an impact on performance and stability when working with large image files, mapping software, and the like, especially those which rely on the use of their own "scratch" files, and especially in situations where I am using multiple applications simultaneously, if I haven't defragmented the drive for a while. For me, defragmenting (I use iDefrag too - it is the only third party app I trust for this after seeing people with problems using TechToolPro and Drive Genius for such things) gives a substantial performance boost in this sort of situation and improves operational stability. I usually try to get in first these days and defrag more regularly (about once a month) when the drive is down to 30% free space or lower.
Between 20% and 10% free space is a bit of a "doubtful region". Most people will still be able to defrag successfully in this sort of area, though the time taken and the risks associated increase as the free space declines. My own advice to people in this sort of area is that they start choosing their new , bigger HD, because they obviously are going to need one very soon, and try to "clear the decks" so that they maintain that 20% free buffer until they do. Defragging regularly (perhaps even once a fortnight) will actually benefit them substantially during this "phase", but maybe doing so will lull them into a false sense of security and keep them from seriously recognising that they need to be moving to a bigger HD!
Once they are down to that last ten per cent of free space, though, they are treading on glass. Free space fragmentation at least will already be a serious issue on their computers but if they try to defrag with a utility without first making substantially more space available then they may find it runs into problems or is so slow that they give up half way through and do the damage themselves, especially if they are using one of the less "forgiving" utilities!
In this case I think the best way to proceed is to clone the internal drive to a larger external with SuperDuper, replace the internal drive with a larger one and then clone back to it. No-one down to the last ten percent of their drive really has enough room to move. Defragging it will certainly speed it up, and may even save them from major problems briefly, but we all know that before too long they are going to be in the same situation again. Better to deal with the matter properly and replace the drive with something more akin to their real needs once this point is reached. Heck, big HDs are as cheap as chips these days! It is mad to struggle on with sluggish performance, instability, and the possible risk of losing the lot, in such a situation. -
How can I move the photos I have in iPhoto to an external hard drive and use that as my library?
I bought a new Mac Pro. My old computers main drive is so bloated that I need to reduce it's size. I want to move my photos, music and movies to an external hard drive and have iPhoto, iTunes, and iMove access them there.
How do I do that so it work?
Thanks,
KeithMake sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.
There are similar options for iMovie and iTunes, but best to check their forums for details.

Moving Content to External Hard Drive and Using New Computers
Before doing this, I want to make sure I know how to do all of it:
We are going to buy two new laptops, and retire the old one. I want to move all of my iTunes content from the old laptop to an external hard drive attached to an Airport Extreme. I then want to be able to share the content between the two computers. I know how to do this, and plan to move the library data base files to the external hard drive, as well.
However, I also want to be able to continue synching all of the content to the Apple TV. To what should the Apple TV be synched after the content is moved to the external hard-drive and the old computer is replaced by two new computers? How is that done under the circumstances? And, in the meantime, will the Apple TV lose all of its content and need to be re-synched entirely from scratch, or will it continue recognizing the current iTunes library as moved to the external hard drive?
Thanks!This is an option, although as a note of caution; depending on how regularly you modify your library this could become a little bit of a chore. The option is likely a good one in many cases but not all.
In my own case I considered using an old mac as my media server in the sense mentioned by tmartine. (I do a bit of experimental stuff and need to restart my mac quite often, I also have 5 Apple tv's and a library which is too large to do anything but stream, my family don't take too kindly to my frequent restarts and I find myself waiting until the early hours).
However I also modify my itunes library on a daily basis, I buy quite a bit of stuff and also add my own movies regularly, as well as make several recordings a day through my eyetv, all this new content would need to be manually added to my (server) library (and deleted manually), I felt this would be too many extra things for me to do and so my personal preference is to have my itunes library on my main computer as the primary library. -
External hard drives and Error Code -36
Just wanted to know if anyone knows what this error code means. I tried copying a bunch of video files about 600-700 mb to my USB external hard drive, and this error message popped up and said the disk could not be read or written to. I contacted the manufacturer of the hard drive and they said it was not a manufacturing fault, but an issue regarding the operating system.
Does anyone know why this might be? And also, does anyone know of anyway to get around it?
Thanks.You can try DiskWarrior to repair the directory. If DW can't do it, you'll need to re-format the drive. I'd also suggest a zero out erase.
Steps for zeroing the drive Disk Utility:
1. Insert your Mac OS X CD-ROM disc or Restore DVD disc, then restart the computer while holding the C key until you see the spinning gear.
2. Once started up from CD or DVD, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from disc to access Disk Utility.
3. Choose the entire disk (top icon).
4. Choose erase tab.
5. Click on "Security Options"
6. Choose "write zeros".
7. Erase
This will take a bit of time because the computer is physically writing zeros to each block.
