2 Different Partition Map Scheme's for one external hard drive

Is it possible to have one external hard drive with 2 different Partition Map Scheme's?
One of them will be used to externally boot tiger on a powerpc, and the other for use on my macbook pro?

And this drive is currently not partitioned I take it ?
You need to make a backup of the data on the drive then partition it, the first partition must be set under Disc Utility / Partition / Options as Mac GUI Bootable so it installs the drivers, then install Tiger onto the first partition and move your current data back onto the second one.
You will then be able to Boot Tiger on the older PowerBook by holding down 'option' at start up, if you just have it connected to the MacBook Pro and start up normally then it will appear as two volumes on your Desktop, the Tiger Boot Volume and your Data Volume.

Which one external hard drive is better for my G5's FW800 port?

Hi,
I use a late G5 under 10.4.11. Last two weeks I used two different Western Digital disks, My Book Studio & My Book Studio Edition II but both of them don't operate well with the FW 800. They conflict with my audio interfaces (FW 400 devices). Only at FW 800. At FW 400 and Usb 2.0 they operate fine.
Because of this I have to replace the WD disk and unfortunatelly I have two options from the store I bought it. And here is that I want your help please.
Which one external hard drive from these two is better for my G5's FW800 port?

Hi-
I think that looking at your other devices is needed.
Check out the Mackie troubleshooting guide for one:
http://www.mackie.com/support/documents/TechFAQno.1.pdf
Page 8 has specific suggestions regarding firewire and chipsets.
The same for the Presonus:
The firewire ports on a Mac (FW400 and FW800) run off the main logic board and share system resources. PreSonus interfaces are designed to be run in series with other firewire peripherals. If you are experiencing erratic performance or pops, clicks, and dropouts, daisy-chain your FW400 peripheral from the secondary firewire port on your PreSonus interface. If you must use a FW800 device, it is recommended to purchase a firewire expansion card for your Mac.
http://support.presonus.com/entries/119100-optimizing-your-computer-for-audio-ma c-osx
It appears to me that both devices require enough resources that the firewire controller of the G5 may be unable to properly support both FW400 and FW800 transfer rates.
It appears that the bandwidth requirements of the devices are forcing the machine to drop FW800 in lieu of supporting FW400.
Both makers suggest use of third party PCI cards for Firewire 800, and it may be that you need additional power to the firewire card to keep up with the I/O and bandwidth demands being placed on the machines by you audio devices.
You mention that someone told you to not use the Oxford chipset, but the best external drives are all those that have the Oxford chipset.
It is important to note that not all WD MyBook drives have the same chipset, and few of the WD drives have the Oxford chipset.
Asrock and VIA are other chipsets for the WD drives.
VIA is notoriously poor as far as Mac compatibility goes.

Can I use one external hard drive for 3 of my Macs?

I have a 2007 white MacBook, a 2011 MacBook Pro, and a 2013 MacBook Air.
I want to be able to transfer all of my precious family photos off of my MacBook and Macbook Pro onto an external hard drive and then wipe those computers clean, and then I want to be able to backup and wipe clean my Macbook Air so that I can update it to Mavericks.
Can I use one external hard drive to do this for three of my Macs? Will it be compatible with all of them? And will I still be able to use the hard drive with my Air once it is updated to Mavericks?
Which hard drive do you recommend?

1. Yes. Note that anything you want to keep should be on at least two drives in case one of them fails.
2. Yes.
3. Yes.

Can I download music and pictures from 2 different MacBooks onto one external hard drive?

I have looked around for the community, but have not found an answer here. Both my wife and I have 2 seperate MacBooks, but we wanted to put all of my pictures and music and all of her music and pictures onto one external hard drive. I read on another board that we can, but only if we purchase a Mini. Is it possible to do that without having to purchase a Mini? Or is purchasing a Mini the only way to be able to do that? Thanks in advance for any replies!

There is no reason that you cannot use a common external HDD for your communal data. Naturally you would have to disconnect it from one MBP and then connect it to the other when you wish to access the data or perform a download.
Any compatible external HDD will do, but make certain that you format it in Disk Utility to Mac OS Extended (Journaled).
Ciao.

I am not much of a computer technician. I bought a time capsule thinking I could use this for an external hard drive and keep my MAC hard drive free. Was I mistaken? One I back everthing up on the TC, can I delete everything off of my MAC?

TC was designed to backup your Mac. The TC literature is pretty clear about this:
If your Mac's hard drive has a problem....it will sooner or later....you can use your backup on the TC to rebuild your Mac.
But.....if you move all of your data to the TC from your Mac....you only have one version of that data now, and it is on the TC.
Have you thought about what will happen when....not if....the TC has a problem? Since the only version of your important data was on the TC, and the TC has failed......you lose all of your data.....because you have no backup.
A much better plan would be to add a USB or FireWire hard drive and connect it directly to your Mac. Move the data on your Mac over to the hard drive.
Then, the TC will backup both your Mac and the hard drive. So, you have original data on on one drive and backups on another drive.
That would be a minimum backup plan. Most of us have more than one set of backups.

My Passport for Mac external Hard drive is not recognized

I recently had to purchase a new MacBook Pro, and when I tried to get files off of my Passport for Mac external hard drive. I get an error stating "The disk you inserted was not readable by this computer." And when I try to initalize, and verify disk, I get this message "Partition map check failed because no slices were found.". I have already updated firmware for the external hard drive. One site I found stated that it could be that the USB port is not strong enough, and I would need a 2.0 Booster cable. Does anyone know if this would work?

What did you old Macbook die from? Likely the HD in it is still ok, yes?
You can remove the HD inside your old dead Mac and put it into a $20 HD enclosure or HD dock, and remove the photos that way, very easy.........IF your old Macbook died from something other than ALSO a bad HD.
You said----my OLD Macbook pro which recently lost video
What happened with your old "dead" macbook? Still have it?

I get error 8062 when trying to copy files from one external hard drive to another. It starts out copying files, but after 10 minutes or so it stops and I get the error 8062. The hard drive tech support says the problem is in my Macbook Air.

I cannot copy my doc and photos and videos from one external hard drive to a second external hard drive -- both plugged in to my MacBook Air -- I get Error 8062 and the copying (which seemed to be going on for 10 minutes) stops and nothing gets copied.
As any Macbook Air owner knows, there is SO LITTLE storage capacity on the computer that you have to back up big files onto an external hard drive to avoid getting the other annoying error that says you have no more memory/storage capacity/whatever the proper term is, and you cannot use the computer.
Backstory: Before this error cropped up, I had backed up lots of files to an external drive and then removed them from my computer. But then the external hard drive got corrupted and I could not access my entire photo library. Had to pay $850 to Kroll Ontrack to recover those files. I have now bought 2 new external 1 Terrabyte hard drives as protection against another such disaster. BUT I cannot copy the files from the first hard drive where all my reovered files now sit, to another backup hard drive.
Feeling vulnerable. Please help.

From the menu bar, select
 ▹ System Preferences ▹ Energy Saver ▹ Power Adapter
and uncheck the box labeled Put the hard disk(s) to sleep when possible, if it's checked.
If the drive has more than one interface (USB, FireWire, Thunderbolt, eSATA), try one of the other interfaces.
Check that the data cable is securely inserted at both ends.
Try a different cable.
If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
If you're connecting it directly, try a different port.
Disconnect all other devices on the bus, or as many as possible.
Test the drive with another Mac. Test another drive with this Mac.
If the drive is bus-powered, but has an AC adapter, connect the adapter.
Start up in Safe Mode and test.
If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive has failed. You may be able to salvage the mechanism by removing it from the enclosure and installing it in another one, or in a drive dock.

How do i make a seperate itunes library for an external hard drive?

my brother bought an external hard drive to have his own itunes library. We attemted to download the program into the ex. hard drive. but what it did was transfer all my music to the ex. hard drive. So we undid it, and now its back on my computer. So what can i do to have a seperate library for the external hard drive?
Windows XP

Choose Go to Folder from the Finder's Go menu, provide ~/Music/ as the path, drag the entire iTunes library to the external drive, and if desired, then to the iMac's internal one. If you put it in a different location than the default, launch iTunes with the Option key held down and point it there.
If the library contains rented movies, those won't play on a different computer.

Can't get LR3 to import photos from one external hard drive to another?

I'm wanting to move thousands of raw photos from a folder in one external hard drive to another folder in a different external hard drive so all my photos are in one photo folder instead of two. I've gone through the importing routine inside of lightroom to move the folder over to the new hard drive. However, the photos don't move because they still show up on the old hard drive and not the new one. What's weird is when I try to import it again, the grid view shows all the photos I'm wanting to import and when I move my cursor over any of the photos they are faded out and it says the photos are already imported. However, if this is true why aren't they showing up in the new folder on my new external hard drive? I know the new external hard drive works fine because I've successfully been putting all my newer photos there since I started using LR about one year ago. The one's I'm trying to move over are older photos I shot try to using LR.
I'm stumped and need some help. Thanks in advance.

You wrote
"Are you saying while I'm in LR just grab the folder I want to move and drop it into the new hard drive"
Yes, that's the way to move photos & folders from within LR.
LR will then update its catalog with the new location and everything should be fine.
Importing is not a good way for moving photos / folders. Since the photos are already in the catalog you had to uncheck <Don't import suspected duplicates> or all the photos will be greyed-out in the import dialog. If you did that LR would import the photos from drive A and put it on drive B. But they would still be on drive A, so you'd have the photos on both drives and would have to delete them on drive A.
But more important: By default LR saves all edits in the catalog, they are not saved with the images themselves. That means by doing an import instead of a drag-and-drop move you'd lose your edits.
You can save your edits to xmp, a side-car file that is stored together with the image file, and the xmps would be imported. But LR does not store everything as xmp. For instance Virtual Copies, Collections, Stacking are saved only in the catalog, so by doing an import you'd lose these things.
Unless you know LR very well, it's best to use the Import Feature only for images that are NOT yet in LR.
And another thing: Before doing major operations like moving big amounts of photos, it's best to backup your catalog first.

Two very mobile laptops, one external hard drive, and iTunes?

I'm very sorry if this has been answered, but I've searched a lot and haven't quite found the precise question I'm asking...
My household has two iBooks (G3 and G4) wirelessly networked through an original Airport. Our music is completely digital, and we have no stereo. Each iBook has a different iTunes library. When we want to play the G3's music, we connect the G3 to a good set of speakers (pretending to be a stereo) through the mini jack. Same for the G4. This would be fine, except we're both running out of internal hard drive space.
So, what we want to do is buy one external hard drive, both store our music files on it, and play music. A new drive in the mid-range should tide us both over till we can afford new computers.
But this has raised a whole host of questions:
1. How do we share a hard drive when we both have laptops that move about the house all the time? Sometimes the G3 sits on the desk playing music while the G4 sits on the couch checking email, and vice versa.
2. Can we set up just one iTunes library on the hard drive that is fully accessible to whichever computer is connected to it, both in terms of playing and in terms of updating?
3. But wouldn't that be terrible, anyway, because I couldn't sit on the couch and download new music into my iTunes folder automatically?
4. And this leads to what I really, really, want, which is an external hard drive that is independently wirelessly accessible by both computers.
5. Which in turn leads to the true wishlist, which is to be able to use AirTunes too. Then I could sit anywhere, access a shared library on either computer, and then stream it to my stereo.
Is any of this possible? Am I missing the forest for the trees? Is there some big picture that I am just not seeing? I just want both computers to be mobile, to each have more space to store music, and each still be able to play that music without the other one having to be involved.
Thanks a bunch -- Discussions is one of my favorite places to lurk for hours.
- Kendra
(BTW, I'd upgrade my Airport if it helped, or buy an Express. And I've seen a lot on Sharepoints, but am not sure if that's what I'm looking for.)

Well to answer several questions at once, there are Ethernet (aka Network) Hard drives you can buy that hook up via ethernet. you could plug it in near your router and then plug the ethernet cable into one of the Router's ethernet ports and set up a network drive. It doesn't have to be connected directly to a computer. Here are two examples (shop around for price, size and features)...

HT201250 I have two macbooks. Can I backup both machines using timemachine on one external hard drive?

I have two MacBooks, both operating on different OS - Leopard and Snow Leopard. Can they both be backed upusing time machine onto one external hard drive?

J D McIninch wrote:
Actually, it does both. However, if you use two machines with the same name, it can pose a problem. If you mount the Time Machine drive and open the backup db directory, you'll note that the subdirectories are arranged by system name. The information about the ethernet MAC ID is in hidden files.
Yes, as posted, to the user it's confusing (and accessing your backups via the Finder is not recommended).
Time Machine knows which is which, and will back up each Mac to the proper folder. When/if you want to use the "Star Wars" display to view or restore from either Mac's backups, it will show the backups for the Mac you're on.

Protection of backups of two machines on one external hard drive

I have one external hard drive which I intended to use to back up two MacBooks owned by different family members. However, it seems that I can access all files on the other person´s backup on the external drive and vice versa, even if our data are protected with user accounts and passwords on our separate machines. Is there any solution to this problem?

You need to partition the drive and each of you should backup to your respective partitions from your computers. You should both be using different usernames and passwords.

How to use carbon copy cloner to back up two computer in one external hard drive

Hello,
I have only one external hard drive which is already used for backing up my old macbook. Recently, i bought a macbook air. Is it possible to use carbon copy cloner to backup my data from macbook air to same external hard drive? If yes, is there anything I should be caucious? If not, could you suggest any other software of other method to backup my macbook air? Thanks!!

Yes, provided you have the space. You will need to create another partition on the drive to use as the backup volume for the new computer.
To resize the drive do the following:
1. Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.

I transferred my iTunes library from one external hard drive to another and added more music on the same day. How do I get rid of my duplicate files without going through them one by one which would take forever?

Please help. I have transferred my iTunes library from one external hard drive to another plus added additional music now I have duplicates of the same music in many albums. How do I delete the duplicates without going through them one by one which would take forever? I understand how to get the "show exact duplicate" feature up on iTunes but, because they were added to the library on the exact day I can't seperate them I'm that manner. So each duplicate is right next to eachother in the exact duplicate screen.

My DeDuper script is designed to help clean up. See this thread for background.

How do I move data on time machine from one external hard drive to another

How do I move data on time machine from one external hard drive to another?

Although the documentation says you can copy Time Machine backups in the Finder, it's very slow and sometimes doesn't work at all.
Launch Disk Utility, open the built-in help, and search for the term "Duplicate." Follow the instructions. Turn Time Machine OFF in its preference pane while copying the volume.
