Ok when you refer to "memory" that is the Random Access Memory which is temporary memory the processor (worker) uses to store stuff while it's using it. Power goes off whats in the memory is gone.
Your storage drive is where data is pernamnetly stored if the power is on/off.
So what you really mean to say is your storage drive is filled up and you need to make some room.
You have a TimeMachine drive, what this does is makes a image of your internal storage drive as a backup method, it also allows some "back in time" restoration of your previous deleted files depending how much space is on that drive. The more space, the less data you have, the more days you can go back in time to retrieve something.
Unfortunatly the TimeMachine drive is not a extra space storage drive, it automatically rotates what appears on your internal storage drive. So if you delete something from the internal drive, it eventually gets deleted from the TimeMachine drive.
So you need to make some more room on your internal drive, this is rather easy, all you need is ANOTHER external drive and connect it to the Mac. Give it a name like ExtraStorage#1 and thenyou will have to decide which of your User files you really don't need on the internal drive.
For instance the best choice would be to move some movies out of your Movies folder to another MoviesExtra folder on the ExtraStorage#1 drive.
Movies take a LOT of drive space and you can always copy them on or off, or watch them from the ExtraStorage#1 drive as well. But if your going to do this a lot, you should consider getting a Firewire 800/400, USB 3,2,1 combination drive as Firewire 800 is fastest and decently priced (Thunderbolt is very high priced and overkill at this time)
The other things like Documents are quite small, Pictures can take a lot of space if you have a lot, but if you need them on the internal drive then that's better. Music one tends to use a lot or manage playlists and such, but perhaps some music you may which to move off or "prune", I suggest always burning data DVD's of music especially for extra backups.
Once you have freed some room on the internal drive, this liitle neat program will show you what is taking the largest amount of space on your internal drive.
http://grandperspectiv.sourceforge.net/
After a scan, right click on the big squares to "revel in Finder" to show you what's taking the largest amount of space, be warned it also opens up hidden system files and folders, which you won't be able to move. So concentrate on what's inthe Users folder.
Likely if you have a lot of Movies this is the biggest culprit on most standard internal hard drives. Also if you have something in iTunes that's auto-downloading something like PodCasts and not deleting the older ones and you forget. So go there and fix things and that can free up drive space.
If you bought a small SSD with your new Mac, then the price of that SSD has come back to haunt you with low storage space, you will have to think carefully what you can live without on the internal drive.
Once you have slimmed things down, TimeMachine will update to reflect your slimmer internal drive. What this means is there is only one copy of your data on the ExtraStorage#1 drive.
You need to maintain two copies of your data at all times on seperate hardware, so now you need ANOTHER storage drive (ExtraStorage#2) to copy everythinng of ExtraStorage#1, or else if you drop or have a mechanical problem with ES#1 all that data will be gone!

    Hello, eco1. 
    Thank you for visiting Apple Support Communities. 
    This sounds like you are wanting to move your iTunes media folder to an external drive and have iTunes this folder from this location.  If this is the case then I would recommend taking a look at the article below.

  • Set up iTunes on a new MacBook Pro to access an existing music library on an external hard drive?

    We just replaced an old MacBook with a new MacBook Pro. We had to keep our iTunes library on an external hard drive because we didn't have space on the old computer. Since our library is large, I'd prefer to keep it that way with the new computer. I want to set it up to see the library on the external hard drive but as I've had issues with iTunes in the past so I wanted to know how to do this from the beginning instead of guessing. Help!

    You have to click on the external drive, you will be able to play your tunes, plg in your external dive then double click on your exdrive, all your music should be there. just click on the song/playlist off the exdrive and they should play.

  • MacBook pro boots to prohibited sign and apple has replaced the Hard drive and it's still didnt fix. They want to replace the hard drive AGAIN?!

    I've had this issue for almost a month now, and they have tried multiple things to fix it from software re-installs to wiping the drive and they replaced the hard drive and cable but now that it is still not working they are suggesting installing another hard drive after it clearly didn't work the last time they replaced it. Help! I've contacted customer relations and the only thing she told me over and over is that they are working diligently to fix it. I'm a music teacher and that is currently the only computer i have and I use July to prep all my lesson plans and music. School starts august 18th and I feel like I'll be back in the store with the same problem again right when school starts. Any suggestions, ill probably be writing a letter very soon, any other suggestions?
    Btw I have tried not backing up from time machine to rule out the possibility of something of mine corrupting it and it still did it.
    Thanks for your help apple community!
    David

    Wholly Crap, No Joke, the lady from the apple store called me up at like 5pm and said "You know what?" and my reply was....... "what" and she goes, "You've been very patient and we understand you've been in and out in the last 3 weeks so we've decided to just give you a brand new computer" She gave me a brand new MBP! SO FREAKIN STOKED, my 2008 macbook pro for a new 2011 2.2ghz with 4 gigs of memory (Upgradeable to 8!!) The only downside is that since I use this for recording audio with Pro Tools well as recording audio with Pro Tools I needed the 7200rpm drive like my last one, and with her eyes i felt the "Beggars Cant be choosy" look flow upon me. But I shrugged it off and She actually told me to take this one, use it for the next week while the one she is ordering for me comes in!! So Bottom line IMHO (first time i've ever used that acronym in a forum) Apple Definitely has some awesome customer service!!

  • Macbook Pro Freezing, Can't back up files either to external hard drive either..

    Hi,
    I'm not entirely sure what happened but my Macbook Pro, (Lion/Mac OS X 10.7.5) just started to freeze a lot. I can hardly browse the web or sometimes browse folders. In some ocassions its even difficult to  check the Activity monitor or go to Disk Utitlity. I always see the rainbow beach ball of death and in the force quit window I see the red "Not responding."
    Because of this issue, I plan on taking my Macbook Pro to Apple but the problem is I can't even back up my files. I just started a time machine and it goes well until in the middle of the transfer it says:
    "The backup was not performed because an error occured while copying files to the back up disk.
    The problem may be temporary. Try again later to back up. If the problem persists, use Disk Utility to repair your backup disk."
    so I tried a different ext. hard drive and still, it says the same message. Upon being fed up of the situation, I attempted to do the old school copy paste from drive to drive but again, in the middle of the transfer it stops and gives me a a differnet message:
    "The finder can't complete the operation because some data in ____ can't be read or written."
    I checked the file and its a .MOV a video file from my DSLR. I skipped this file and then again, it said the exact same message on a different video file. I can't just avoid these video files. I'm actually a film maker and all this clips are in desparately in need to be backed up.
    Does anyone know how to fix this issue? Atleast backing up the files..
    Thanks for the help.
    p.s.
    Not sure if this is related -- since my Macbook Pro has been running slow I deleted a couple of apps such as Things, DaVinci Resolve and FrameForge Previz.. Which to led to having my spolight indexing. I thought it was only the index thats making it run slow but the index done now and I can't back up my files!

    If you have more than one user account, these instructions must be carried out as an administrator.
    Triple-click anywhere in the line below to select it:
    syslog -k Sender kernel -k Message CSeq "I/O error" | tail | open -f -a TextEdit
    Copy the selected text to the Clipboard (command-C).
    Launch the Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window (command-V).
    The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
    A TextEdit window will open with the output of the command. Normally the window will be empty. If you get output like this:
    kernel[0] <Debug>: disk0s2: I/O error
    the boot drive is failing, or there's some other hardware fault in the storage subsystem.

  • I have a macbook air late 2010 and keep getting a warning that my hard drive is full and to delete things so I purchased a external hard drive (1TB) but I'm just not sure what the correct way to transfer and store files to the external drive is. First MAC

    I purchased a macbook air about 5 months ago and lately i keep recieving a warning that the hard drive or disk is full and that I will need to move items to trash in order to free up space on it. I purchased a external hard drive 1 TB but I'm very new to mac and ios and unsure as to how I'm suppose to transfer my files (video, pics, music etc.) from my mac over to the external hard drive in the correct way so I won't end up deleting them permenately or screwing anything up with my mac as far as the applications and programs being able to run. Am I supposed to just copy to the external hard drive and then move to and empty the trash? That's pretty much all I could come up with, but then what if i need or want to access that file again at a later time. Also, I have an i Phone and i pad so with i cloud it automatically syncs all my purcheses and if i delete something from itunes on my mac it deletes from my ipad.
    I'd appreciate any kind of input i think im just a little lost here. I have to say i love my Mac and wouldn't trade it for anything (except maybe a macbook pro w/more memory)... Is there something I'm missing???

    To free up hard drive space the best bet is to move data files that you don't need access to all the time. Likely candidates are music, video, and photos. Things like word processing and spreadsheet files can also be moved but they tend not to be very large and so don't free up much space. The problem with moving the above mentioned files is that iTunes and iPhoto need to know where the files are stored.
    Here's an article explaining how to move the iTunes folder. You can move the iPhoto library using the Finder but there is a slight complication. Start iPhoto, open the Preferences and click on the Advanced tab. The first option is "Copy items to the iPhoto Library". If this option is checked, copy the iPhoto library to your external folder (drag it from the Pictures folder to your external drive) and then delete it from your Picture folder. If this option is not checked, it is a bit more complicated and we'll need to talk a bit.

    I just bought a MBA and I need to move my photos and itunes to an external hard drive (from my old MacBook Pro) because they won't fit on the Air.  I got the photos moved fine and I followed an online tutorial to move the necessary files for itunes, but it didn't work.  The files copied fine, but when I tell iTunes on the Air to look at the external drive for the library, it doesn't find anything.  What I copied was the entire iTunes Media folder.  So, how do I move the necessary iTunes files from my old Pro to a external drive so I can access them from my new Air?  Whew!

    iTunes- How to move the library to an EHD
    After you move the library you need to open iTunes by first depressing the OPTION key then launching iTunes. You will be given a choice of which library to use. This can then be made a permanent change, if you wish, in the Advanced section of iTunes preferences.

  • Is it possible to run two different versions of Apple operating system (for ex. 10.6.8 and 10.9) on a MacBook Pro, either on the same disk or from an external hard disk? If so, where would I find the details?

    Is it possible to run two different versions of Apple operating system (for ex. 10.6.8 and 10.9) on a MacBook Pro, either on the same disk or from an external hard disk? If so, where would I find the details? (In order to be able to use the older applications no longer supported in 10.9)

    If you want to add a second partition to the internal drive (in Disk Utility, select the drive, then open the partition tab and just click the + button), you should first be sure that you will have enough room to accommodate whatever the second volume will be. I am currently doing this for Snow and Mountain Lion.
    To get to whatever volume is not the startup disk, restart and hold down option/alt at the chime, which will bring up a selection of the two volumes. Use the left or right arrow keys to select it and then hit enter/return.

  • Is it possible to have two USB drives for the IPad?  I want to bring RAW photo files from my camera, through the IPad and back to an external hard drive.  One of my cameras does not use an SD card.  How can I do this?

    Is it possible to have two USB drives for the IPad?  I want to bring RAW files from my camera through the IPad and out to an external hard drive.  One of my cameras has an SD card but the other one doesn't have a card that would fit in any of the camera devices I've seen on line.  Realted to this, I bought the IPad camera accessory.  Can I put the SD card in the device and also hook the external hard drive to the USB port of the accessory and download from the camera to the hard drive?  Can I put Lightroom or the Nikon photo editing software on the IPad?  Right now I carry a PC laptop and external hard drives with me on wildernes trips.  Internet and WiFi are not available.  Because I shoot so many photos and they're in RAW I need to download from the camera to the external drive because I run out of memory on the PC (and it has much more memory than the IPad).  I have Nikon NX software and lightroom on my PC.  I'd love to be able to reduce the weight I carry by using the IPad to edit my photos each night while on trips.  Is this possible and how would I do it?  I'd appreciate any guidance.

    No, the camera connection kit only supports the copying of photos and videos to the Photos app, it doesn't support copying content off the iPad. For your second camera instead of the SD reader part of the kit, does the iPad to camera cable not work with it for direct transfer to the iPad ?
    For Lightroom and Nikon software again no - you can only install apps that are available in the iTunes app store on your computer and the App Store app on the iPad, 'normal' PC and Mac (OS X) software are not compatible with the iPad (iOS). There are some apps that perform fairly basic editing functions that are available in the store, but nothing as sophisticated as, for example, Lightroom.

  • I cannot find videos (not movies) that i have transferred to my macbook pro from an external hard drive, these files used to be on my windows PC!

    I cannot find videos (not movies) that i have transferred to my macbook pro from an external hard drive, these files used to be on my windows PC. Photos and a few of the videos came over but i am missing the majority of the videos. Help please!!! I have tried omnidisksweeper with no success in finding them.
    in my Usage it says i have over 40 gb of movies when i only have about 9gb which i can see using spotlight search. i really hope the other amount is my missing videos! these are videos of my kids as babies.

    Read this post and do the migration again, putting the library in a portable shape first if necessary.

  • I have a 15" MacBook Pro with Mountain Lion installed.  I have partitioned the hard drive into two partitions.  Is it possible to install Snow Leopard on the second partition?  If so how do I do it?

    I have a 15" MacBook Pro with Mountain Lion installed.  I have partitioned the hard drive into two partitions.  Is it possible to install Snow Leopard on the second partition?  If so how do I do it?

    If your MacBook Pro had Snow Leopard on it at one time then sure. (Early 2011 or earlier)
    How to erase and install Snow Leopard 10.6
    Obviously choose the second partition to install into. It has to be OS X Extended journaled formatted in Disk Utility (BootCamp software makes it a MSDOS/FAT32 formatted partition if you used that to partition with)
    If it's a Early 2011 or Late 2011 that came with 10.7, it's possible, but it's not easy.
    https://discussions.apple.com/thread/3264421?start=0&tstart=0
    If you can't install Snow Leopard, there is a thread over at MacRumors how to run Snow Leopard in a virtual machine program under 10.7 or 10.8

    Well you won't have very much storage capacity with a SSD that small, also SSD has limited writes, so it wouldn't be good for on-loading and off-loading a lot of files.
    SSD isn't being securely erased due to steps to prevent their premature wear, so despite what you do in Disk Utility Secure Erase, your confidential data can still be recovered if you pass the machine on to someone else for instance.
    Other than those reasons, small SSD's can be extremely fast, loading your programs and OS much faster. But the real benefit in high speed storage is transfering large amounts of files on/off the computer to ANOTHER fast device. This comes in handy for video and large music collections and so forth.
    Since the SSD because of it's limited writes doesn't fit the bill as a large file transfer medium.
    If you want to get a SSD drive, you can upgrade it yourself simply by ordering one online at locations like Other World Computing or NewEgg and have a 00 micro phillips head screwdriver handy.
    There are instructions over at iFixit for opening your MacBook and replacing the hard drive with the SSD.
    Preferably you will want to clone your present boot drive to a external drive using Carbon Copy Cloner, then making the switch and hold option to boot from the clone and then clone from the external to the new internal SSD drive.
    Prices of SSD are varied, Apple won't replace it for you
    This is currently the fastest SSD availalbe
