Not Allowing Me To Use External Hard Drives

I have a Lacie that I've used in the past on my older MacBook Pro with no problems... On my brand new MacBook Pro it is telling me that it is read only - it won't allow me to use it as a Scratch Disc with Final Cut and it won't allow me to drag any of my footage into it. What do I have to do to get external hard drives to work with this MacBook Pro? Thank you.

Any chance it was formatted as NTFS? Mac can read that, but cannot write to that without third-party software help.
- I'm going to reformat it now and give that a shot...
Good. I would zero the drive (Options > Zero Data). Format as Mac OS Extended (Journaled) and partition as GUID.
This new MBP has been a little fishy with another drive I have as well
Hmmm, it shouldn't act any different than an older MBP . . . .
- a brand new 2TB Lacie right out the box! It wouldn't let me drag files into OR use it as a Scratch disk for Final Cut but last night
By chance does it have any software pre-installed on it? Whether it does or not, I'd zero/format/partition it.
it DID let me use it as a backup disk for Time Machine!!!
If there's something amiss, I don't understand that.

How do I use external hard drive

how do I use external hard drive and Photos? I keep getting a msg that there is not enough free space on your photo library volume - i even bought 500Gb of space on iCloud.... that didn't even work please help

1. Drag the library to a volume formatted as Mac OS Extended, launch Photos with the Option key held down, select Other Library, and choose it. Alternatively, drag it to the Photos icon in the Dock.
2. iCloud storage space is separate from that on the computer.

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 On the ones it cannot play it asks to locate, then refers to an archived version (an .itl file), and still cannot play them.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!*

my final cut is running extremely slow after having for 6 months. I use external hard drives and save nothing on my computer. it takes a long time to render now. do you think something is wrong with computer. took it to mac store but they fail to help me. I have a 13 inch mac book pro 10.6.8 8gb 2.3 gfz intel core i5

What did Apple tell you about what they did (or did not) find here?
See if working on the main disk is any faster.
USB2 is glacial, as I/O interconnects go. And USB2 disks have been known to fail, or sometimes to drop back to USB1 speeds, too. FireWire 800 is substantially faster than USB2, but still not as fast as the internal drive connections can provide.
Put another way, start varying your configuration, and see which configuration changes (still) have the problem, and which don't.

Can you use external hard drives with the HP Omni 10 5600US

Since this a Windows tablet, can you use external hard drives with the HP Omni 10 5600US?
I know there is a micro-sd reader for additional storage but can you use the usb for external hard drives like a regular pc?
I tried looking at the spec's for this tablet and it said the usb port was host only. I'm not sure what that means exactly.

Yes you can. You'll need to purchase a USB OTG (on-the-go) cable. I recommend using a drive that has its own power supply but I've successfully used small USB powered drives also.

I can not save any data to external hard drive from my mac pro. Is there anyone can help me in this regard?( note, when i first plug my ext. drive to mac i chose option to backup later)

The device may be formatted for Windows, as NTFS. The format is readable, but not natively writable on a Mac. To write to the device, you must either reformat it (erasing all the contents) or install third-party software to enable write access to NTFS.

Looking to move data from OSX 9 to Mountain Lion using external hard drive?

Thanks. I'd like to get rid of this OSX 9 after retrieving a few files. If I wanted to erase it's hard drive before I do so, would powering off then on again and immediately start tapping the F10 button do the trick as it does with a PC?

I have moved all of my movies from "Search for - All Movies" folder thinking they were shortcuts to the trash folder by mistake. Is there any way I can restore them to the right place on my system Note most are on an external hard drive. :(

You can drag them out of the trash folder to wherever you wish. There is no automatic way to restore them.
If you have a recent backup of your computer (at the risk of preaching, everyone should have one), restore them from there.

P.S. I have no clue what you did or why you have 44,000 on the external drive

First time using external hard drive for backup of computer....

First time using external hard drive for backup of computer....it asks "Do do you want to erase disk?" In order to proceed, I have to say "yes" ... is that what I want to do? ...Seems like I'm skipping a step...

To use Disk Utilities, attach the drive, open Finder > Applications > Utilities > Disk Utilities and then highlight the LaCie drive in the left panel of the DU window. In the right panel, choose the Partition button top center of the pane. Then decide how many partitions you want on the drive, one is just fine.
Then choose the format, the default is Mac OS Extended (Journaled) which is prefered.
Then name the partition or drive.
Then choose the partition table, the default is GUID which is prefered.
Then Apply and you will get to confirm that you want to erase and format the drive.
Quit DU and you are ready to go.

Tried to use home sharing to transfer itunes library from old pc to new -- however it only brings over the music, did not bring audiobooks- My question is do I need to delete itunes from my new pc when I redo using external hard drive

Trying to transfer iTunes library from old windows 7 pc to new windows 8.1. Used home sharing, but not what I wanted, I want everything on the new so I can discard the old pc - so now all I have is my music library on new pc thru the cloud none of my Audible audiobooks came over - My question is do I need to delete iTunes off my new pc before I load it in from a external hard drive?

You might need to make sure neither is going to sleep (System Prefs > Energy Saver)
Also check your settings under System Prefs > Security. My sisters new laptop kept logging off due to some setting there.

Ethernet not connected when using external hard drive

My brand new Mac Mini (mid 2010) works fine when I connected it out of the box to my router via Ethernet cable. But when I boot that new mini using an external hard drive (La Cie 500 GByte Firewire 800 connection), the Ethernet shows up as "Not connected". It advises that I should plug it in, or the other end may not be plugged in. But when I simply reboot again to the internal hard drive, without changing any connections, the internet connection works fine. When I boot a different and older Mac Mini (2.0 GHz Core Duo) off that same external hard drive (using Firewire 400 of course), the internet connection works fine. I'm stumped despite using Macs since 1986. I tried automatic mode, but I can't get far, because it thinks there is nothing plugged into the Ethernet port. But there is, and it even works when booting off the internal hard drive. Both the internal and external OS are at 10.6.4, latest. I also tried erasing the internal hard drive so it couldn't get confused, but that didn't help. What else to try?

The ethernet service has nothing to do with the cable plugged or not, and the ethernet cable is working fine with the other system, so definitely the issue with your other OS. Forget about the working OS for now and boot into the OS that has the problem and select the ethernet service from the service list in System Preferences > Network then click on minus button then apply the changes then click the plus to add it again.
If this didn't work, go to :
/Library/Preferences/SystemConfiguration
and trash the NetworkInterfaces.plist file then restart and see if it solves the issue.

Help with using external hard drive to boot windows on PC

Hi,
I'm not sure if this is in the right place, so apologies in advance if not. I've looked around the internet for a good while now, and I haven't found anyone in my exact position.
My PC's hard drive (running Windows 7) recently died; long story short, I am attempting to reinstall windows. The only other computer I have is this MacBook Pro, on which I have an .iso file of Windows 7. So I want to use my external hard drive (WD 500GB "MyBook") as a boot device so that I can install Windows onto my new internal hard drive.
The problem I am having is that, well, nothing seems to be working. Every time I try to load the .iso onto my external hard drive and boot my PC with it, either a blank screen appears or it says "missing operating system".
I have made sure that the BIOS is running the external hard drive as its boot priority.
I have tried using Disk Utility to partition the external drive, then using 'Restore' to load the .iso onto the partition, to no avail.
I have tried simply dropping the extracted .iso files onto the hard drive, this doesn't work.
I have also tried changing the file system of the external hard drive using the 'Erase' feature (NTFS-3G (using an addon), FAT32, exFAT, all of the others), but I notice that whenever I use Restore after doing this, the file system seems to return to Mac OS Extended, which might be why it isn't booting up on my PC. Is there any way I can succesfully partition the external hard drive in a format that will allow Windows 7 to boot (such as NTFS?), and is Disk Utility even the right program to do this?
If you want any more information from me, please let me know and I'll do my best to provide it - I'm not the most advanced mac user in the world, but I've spent days trying to fix this problem and nothing, no combination of anything, seems to work at all. So any help will be greatly appreciated!
Thanks

Here is a quick suggestion for you:
Download Virtual Box (free PC Emulator for Mac) and install Windows 7 on your Mac (don't worry about activating it yet, as you don't need to keep it more than a few hours). You can tell Virtual Box to use the ISO file as the DVD drive for your virtual Windows computer, so no need to burn a disk.
Search Google for creating a bootable USB installer for Windows 7. I found a link that gave good instructions on how to do this using DiskPart.
Follow the instructions to make the bootable USB stick for installing Windows 7 using your virtual machine you created above.
Use the USB stick to install Windows on your new PC.
Remove the virtual Windows machine from your Mac.
Remove Virtual Box from your Mac.
I found a set of instructions and built an installable USB stick last night that worked great for installing Windows 7 Pro (64 bit) onto my older ThinkPad I had sitting at home. The USB installer also installs in about half the time as a DVD install. The only reason I have you create the virtual Windows PC is that all of the instructions for makeing the Windows install USB stick are written assuming that you already have access to a running Windows PC. By doing this install, you have up to 3 days before you would need to activate it and you can build the installer USB stick and remove teh virtual computer long before that.

A zillion questions about setting up and using external hard drive

Hello. I recently purchased a Cavalry 440GB CACE USB/FW800 7200 RPM 3.5 in Mac Formatted hard drive. My Mac is a Power PC G4 using OS X 10.2.8.
After much back and forth with the Cavalry support desk, I was able to connect it to my Mac. (The USB cable included was not compatible--fortunately, my printer cable was.)
Through Disk Utility I see that my Mac is detecting the hard drive, but there's no icon on my desktop. My questions are as follows:
1. How do I get the icon on my desktop?
2. It was suggested on this board to partition the hard drive. What exactly is partitioning, and is it necessary?
3. If I do partition the hard drive, into how many partitions should I make it?
4. Once the number of partitions is set, can that number be changed? In other words, can it be repartioned without erasing anything?
5. My main purpose for getting the external hard drive is to move all my movies off my Mac. I'm sure I will want to back up other files as well. Should I create one partition for all the movies, and one for photos, one for files, etc.?
6. Once I get the icon on my desktop, is transferring files as simple as dragging the files onto the icon?
7. Once I move files to the hard drive, is it simple to move them back to the Mac if I need to use them again?
OK, that's all for now. I appreciate your patience in dealing with all my questions! Thanks.

Hello,
I'll try my best on the first seven. The remaining zillion minus seven questions will have to wait!
1. If the drive really is Mac-formatted it should just appear. Firstly check that hard disks are set to appear on the desktop. In the Finder go to Finder > Preferences... >General tab and ensure that the box to show hard disks on the desktop is checked. If that doesn't work go to Macintosh HD > Applications > Utilities >Disk Utility. Select the drive in the left hand pane and then click on the "Erase" tab. Erase the disk and ensure the format is "Mac OS Extended (with Journalling)".
2. Partitioning is splitting the physically drive into two or more volumes. This will allow you to compartmentalise your data. You will have two or more icons appear on the desktop if you do partition. Although they are on the same physical disk you will be limited on each of the volumes to the size you set at the time of partitioning. If you do partition the drive be sure to use the "Apple Partition Map" not "GUID Partition Map". The latter is for Intel Macs.
3. Whatever you want. My experience is that too many partitions and you loose flexibility in your storage space. Personally on my external drive I have a partition that is exactly the same size as my internal hard drive. I then use that to do a regular clone backup. I then have a second partition for general use. This means I can put files on the external but still guarantee I have enough spare to backup fully.
4. No. Not without third party tools.
5. As I said above, in my opinion the best use is to create a partition for backup and a partition for all other use.
6. Yes absolutely. However if you plan on moving libraries like iTunes or iPhoto then you'll need to show the applications where the libraries are again.
7. Yes.
Some extra pointers:
A. Use Carbon Copy Cloner to backup your internal drive to the external. Clones are fantastic backups as even if the internal drive bursts into flames you will have an identical copy of all user data and settings: http://www.bombich.com/software/ccc.html (scroll to the very bottom for the version suitable for 10.2.8).
B. Don't use USB to connect the hard drive it's not very fast. Firewire 400 is significantly faster and will allow the iMac to be booted from the external drive in an emergency (USB will not boot a G4 Mac).
Hope that helps a little.

Using External Hard Drives...

How many external hard drives can be connected to FCP? I am NOT asking how many can be connected at one time.
In the scratch disc section, I have my external set to capture video/audio and to save project files and self contained movie files and other files pertaining to my projects. For the most part this drive stays at home since it needs AC power to run.
Now when I am on the road traveling and want to use a whole seperate drive to capture to how do I go about setting that one up?
I tried doing this a few weeks ago and it wouldn't work. FCP wouldn't allow me to set up the new external hard drive as a scratch disc until I cleared out the drive I use at home which I thought was pretty odd since there are several options where I could add additional external drives.

Ok understand that but let me ask you this. I have a Lacie external drive that I use to capture and save files while I am working at home. I can take it with me but would need AC power. Now I want to get one those 500 GB (pocket drives) that run off USB that I can use while I am traveling (on the plane or whatever). Do I just go to my Scratch Disc option and list the "travel drive"? Does that drive have to be hooked up to the computer when I am setting it up?
So in a nutshell, I would want a drive to use at home and another when I am traveling but have them both listed in my scratch disc section. When I tried this 2 weeks ago, I had to clear my other external drive from the list before I could set up the new drive.
