Lost ownership and permissions on an external hard drive
Hey,
I have a LaCie 500GB external HD that i connect to my MacBook via firewire.
I was checking the amount of space left of the external HD by clicking command-I on it. I accidentally changed the ownership & permissions and now my account has no access to it. I can't see the HD on my desktop but when I go into Disk Utility, i can see that it's there but I can't repair its permissions.
to see whether I could still have access to it, I created another user account and gave it admin status and am able to access the HD there.
Is there any way to restore the ownership and persmissions of my external HD on my primary account?
i feel stupid
many thanks
I was excited by a resolution to the same problem I have (I don't know what Ownership & Permissions I should have on my external -- bootable -- HD). Mistakenly I used Leopard to set them up rather than Mac OSX 10.4.11. Now I no longer had access to the HD nor would it show up on the desktop on Mac OSX 10.4.11 although the Disk Utitlity showed that it existed. I finally erased and cloned the disk but don't know what Permissions I should set it at. "Niel" supposedly answered this problem but his answer was "click here and follow the instructions" which does not show up on the forum. I can't find any other discussion of my specific problem nor an explanation of various permissions sets for Hard Disks internal nor external. If someone could help me I would be grateful. I am in Japan far from any Apple Stores or shops. Thank you.

I just backed up my mac to an external hard drive using Time Machine. What would happen if I turn Time Machine off and then plug the external hard drive back into my computer?
What I am ultimately wanting to do is make more room on my computer by backing up all of my files onto the external hard drive and then deleting them off of my computer. However, neededing to be able to retrieve them from the external hard drive later down the road.
From what I have read and am trying to understand, is that I probably shouldn't have used time machine. I need to use the external hard drive like a basic flash drive where I can put things on and get things off without having it automatically update through time machine everytime I connect it to my computer.
Not tech savvy at all and barely understand basics. I need very simple and easy to understand explanations.sydababy wrote:

BIG BIG MISTAKE ..... youre making a linchpin deathtrap for your data trying to shove everything on a single fragile HD.
Dont suffer the tragedy other people make, buy another or 2 more HD, theyre cheap as dust.
The number of people who have experienced terror by having a single external HD backup is enormous. One failure that WILL HAPPEN, and kaput,......all gone!
Dont do it, its all about redundancy, redundancy, redundancy.
follow here:
Methodology to protect your data. Backups vs. Archives. Long-term data protection
Deleting them off your computer is fine....having only ONE copy is extremely BAD.
The Tragedy that will be, the tragedy that never should be
Always presume correctly that your data is priceless and takes a very long time to create and often is irreplaceable. Always presume accurately that hard drives are extremely cheap, and you have no excuse not to have multiple redundant copies of your data copied on hard drives and squirreled away several places, lockboxes, safes, fireboxes, offsite and otherwise.
Hard drives aren't prone to failure…hard drives are guaranteed to fail (the very same is true of SSD). Hard drives dont die when aged, hard drives die at any age, and peak in death when young and slowly increase in risk as they age.
Never practice at any time for any reason the false premise and unreal sense of security in thinking your data is safe on any single external hard drive. This is never the case and has proven to be the single most common horrible tragedy of data loss that exists.
Many 100s of millions of hours of lost work and data are lost each year due to this single common false security. This is an unnatural disaster that can avoid by making all data redundant and then redundant again. If you let a $60 additional redundant hard drive and 3 hours of copying stand between you and years of work, then you've made a fundamental mistake countless 1000s of people each year have come to regret. -
How do I keep photos and videos on an external hard drive and run the application on the macbook
I am running out of space on my Macbook and would like to move all my photos and videos to an external hard drive to free up disk space. How do I designate those drives as the destination drive when running the application (iPhoto, iMovie) on the Macbook.

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. -
How can I put my recently purchased iTunes movies onto my thumb drive and WD my passport external hard drive.My Mac is saying that can't be copied because it is too large for volumes format
[file] is too large for the volumes format
That is usually an indication that the Volume was never Erased or Partitioned for GUID partition table and Mac OS, and is still in a Windows format.
Mac OS X Extended (journaled) has no such file-size limitations -
I have two iPhoto libraries: one on the hard drive, and one on an external hard drive. I cannot access the iPhoto library on the external hard drive. Yes, it is plugged in!
How are you trying to access the EHD library? Can you open it by launching iPhoto with the Option key held down and selecting the EHD library in the window that appears?

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!

Can I play my movies and music from my external hard drive or do I have to reinstall it on my computer?
Hello B3NN13,
If you would like to add the music from your external hard drive to iTunes without copying it to the iTunes Library on your internal hard drive, you may find the following article helpful:
Add files to your library without adding them to your iTunes folder
When you add an item already on your computer to your iTunes library, iTunes places a copy of the file in your iTunes folder. The original file remains in its current location.
You can change this setting so that files are added to your iTunes library without being added to the iTunes folder. You might want to do this, for example, if you prefer to store video files on an external disk but still want to view them in iTunes.
Choose iTunes > Preferences, and click Advanced.
Deselect the checkbox next to “Copy files to iTunes Media folder when adding to library.”
From now on, when you drag a file to your library or choose File > Add to Library, the item appears in iTunes, but the actual file isn’t copied or moved.
Tip: You can temporarily reverse this setting by holding down the Option key while you drag files to the iTunes window.

Can I view photos and movies from my external hard drive? I used Time Machine and a WD Passport for backup. Since my drive on my MacBook Pro is filling up I was planning to delete some of the movies and photos. I wanted to see if I could view them from the hard drive. Thanks
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.

Can you save your itunes and songs onto an external hard drive so that incase your computer crashes you will still have all your music?
The procedures below are for "moving" your library but as long as you don't delete it from your internal drive you are basically backing up.
iTunes: How to move your music to a new computer [or another drive] - http://support.apple.com/kb/HT4527
Simple answer: Copy your whole iTunes folder to the external drive. For subsequent backups you might want to learn about cloning and using a tool that only does incremental backups of recently changed items rather than copying all your files each time. -
Macbook Air 13 inch purchased October 2013. set up to save [mainly photos] to external 'hard drive' i.e. not saved to internal hard drive. Cannot find easy way to create 'back up'. Please advise how I can reverse i.e save directly to internal 'hard drive' and 'back up on external 'hard drive'
For backing up your data I recommend that you use Time machine:

When you import images or create other data files, file them in the appropriate places on your internal drive, don't delete them and let Time machine back them up.

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!

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. -

I want to move imovie projects and events to an external hard drive. Where is the "move" command?
I want to move completed imovie projects and events to my external hard drive. I see in the "help" section that I should "move project & event" and they indicate that their should be such a selection. I highlight the project I want to move and attempt to drag it to my external HD but it won't stay. I never see "move project & event". I've tried holding the "command" key down while dragging and that doesn't work either. Help ...
Hi
Moving Event's and Project's
Connection - Either connect one Mac in Target mode to the other via FireWire. Or use an external hard disk !
(Target-Mode - Start one Mac e.g. laptop - BUT keep T-key down during full up-start - Now a FW-symbol is jumping around the screen and it will work as an external hard disk when connected to the other Mac)
A. The External Hard Disk - MUST BE - Mac OS Extended (hfs) formatted to work for Video. UNIX/DOS/FAT32/Mac OS Exchange works for most other things but not for Video whatever program is used (iMovie or FinalCut)
B. Should be a FireWire one as USB/USB2 performs badly to me and especially when filling up
C. Do never Move or Alter any folder named
• iMovie Event's - or -
• iMovie Project's
on DeskTop/Finder - as this will result in iMovie losing connections to them and repair can be anything from hard to impossibly
D. Moving and Copying must be done within iMovie application and Events to Events - and - Project's to Project's.
E. Moving Project's to Event's - Do not work for me - I have to export project as a QuickTime movie then Import this into Events.
Event's window can show two faces
Like this
or like this
from one hard disk Event - You can move it to the other hard disk
You can not (at least not me) move Event to Project or other way around only
Event to Event and Project to Project
