Connecting 2 Macs to an external hard drive

Hi,
I have an iMac G4 and a Mac Mini (with Panther on them). The hard drives for these two macs are running out of space due to a large library of music, video, and photo. I am thinking of getting an external hard drive and move all these to there.
My question is, am I able to hook these two macs to the external hard drive and access the file? Do I have to partition the hard drive into two so that each Mac will have its own partition on the hard drive?
Thanks, guys.
iMac G4, Mac Mini Mac OS X (10.3.9) Mac Mini

An external hard drive can be shared by two computers, but both computers can't be plugged into the hard drive at the exact same moment. However, if you have iTunes or iPhoto running on the one computer with the hard drive, you can share your music and pictures to the other one. You could also turn on File Sharing on the computer with the hard drive and then you could connect to the hard drive across your network to access or share other types of files.

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.

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.

More information would help. How is the external connected? Does the external appear on your Desktop? Has the external been formatted for a Mac? What method do you use to transfer files? When you try to move a file to the external, what does happen?

Can i back up 2 macs on one external hard drive?

can i back up 2 macs on one external hard drive?

If the external drive is large enough, yes.
Recent versions of Time Machine will do this across a properly set up and Shared network connection or to a drive on a Server. But you may be unhappy with the amount of Wireless traffic generated to perform the backups, especially the initial full backup.
Utilities like Carbon Copy Cloner will do this ONLY when performing a file-by-file backup. A "Disk Image" backup reproduces the Source disk, including blank space, and fills the entire Destination drive with the Source Disk image.

After clean install of Snow Leopard, Time Machine did not restore all files. When I try to restore these files I get "Not enough disk space" error. What do I need to do to get these important files back onto my Mac from my external hard drive??

About 3 years old...pretty dated now I guess. Am thinking I may just need to have it upgraded by a Mac tech.
For what the Apple Store's charge you can buy almost buy a new computer.
Just for giggles I brought my old laptop in for a drive upgrade and asked, they wanted $600 for a drive that only cost $120 at the time and it was a slow 5,400 RPM drive. The new Mac's of a similar make were going for $1000.
I did the drive replacement myself, got a faster drive of better quality for $300 instead.
Then another time I asked for a RAM upgrade from 4GB to 8GB, they wanted to charge $400 + $35 for the labor.
The same RAM is on Crucial.com for $90 and all I need is a 00 micro phillips screwdriver.
So you see what's going on here.
I think what you should do, if your out of warranty/AppleCare, is to call up the local PC tech guy who also does Mac's and have them fix you right up.
They can offer more personalized care which you need. Clone your old drive to the new and everything.
With Apple they are overworked at the Genius Bar and just place roadblocks so you buy a new machine instead.
For instance, all new iMac's now have proprietary drive software installed on the hard drives for heat monitoring. So now the only choice a user has is to bring their iMac into a Apple Store for a very expensive drive upgrade, which a person then decides the money is better spent buying a new machine.

Sync a folder on my Mac with an external hard drive

Is it possible to use the time machine to sync a folder on my Mac with an external hard drive?

Not using time Machine.
I use ChronoSync. Works great for me.

Mac air with external hard drive - not being found on Finder, Time Machine, Migration Assistant

I have been using an external drive (Imation Apollo) to access only, old files from previous computer (PC) on a new Mac Air. I had not transferred them across to new computer (didn't want to do that) just accessing them from the HD. It had been working fine until recently. Each time the external drive had been connected Time Machine would come up and ask if i wanted to use this drive for back ups, and I always chose 'Decide later'. So, as yetI hadn't as yet configured Time Machine to do back ups.
Recently I noticed that the extrnal HD was no longer showing up on Finder. Slight panic as i have 5 or 6 yrs of work saved on that HD
Further investigations - it's also not showing up either on on Disk Utility, or on Migration Assistant.
I've done the following:
Tried HD in each of different USB ports - made no difference, HD still not showing up
Tested different Hubs in each port with HD attached - no difference HD not showing up
Tried USB flash drives in the USB ports - These are working fine and show up on finder
Tried the HD on other comptuters (a PC though, don't have access to another mac to do this test)- working fine, the HD is showing up and is accessable
Interrogated the Console logs to try to see if the act of attaching the HD creates a log entry - couldn't find anything
Rebooted computer via shut down, power disconnect - no difference
Reset PRAM - no difference still not showing up
Reset SMC - no differnce still not showing up
So I think I have established that all the USB ports are functioning correctly and able to access other external drive devices, using hubs with external powersource is not the issue, identified that the external hard drive is working OK, and it appears that the Mac itself is functioning normally.
What would be the reason the Mac now does not allow this specific external HD to be identified and accessed. The only possible things I can think of are
if I had in fact pressed 'Do not use' when Time Machine asked 'do you want to use this drive for back ups'. Would that mean that the Mac now totally rejects this HD from being a source of accessible files - I hope not!
I also think that my husband may have disconnected the hard drive from my computer to access some stuff and he just yanked it out rather than use the safe eject method. Could this create an issue? The Hard drive works fine on his PC.
Why is my Mac Air now rejecting this HD and what can I do to access my historical files now.
Any assistance anyone can provide would be very greatly appreciated!
Thanks
Anna

I can't answer why it isn't accessing it, but I have a slightly related issue w my back up drive starting to get noisy.
Realizing that redundancy is safety for critical data. I talked to my brother about my situation the other day & he said he has 3 small Western Digital portable HDs that he rotates for backup. He even keeps 1 in the safe deposit box.
I have read for some time that we should have multiple back ups & also have our critical stuff backed up off site. Amazon HD reviews had a woman telling about how she was very backed up on multiple computers & hard drives, but they were robbed or burgeled & all of them were stolen including her thesis that was on the computers.
Hard drives aren't that expensive. I just bought a new Western Digital 1 TB drive for $89.99. I plan to use it to back up the Seagate that is getting noisy & then maybe alternate them.
Also, when I came back to Mac, I moved practially all of my documents to Mac. I think I just dragged & dropped or something. Photos, Office, & pdfs do fine that way. & then you could back them up to a couple of different external drives & remove from your MacBookAir.
Unfortunately I think most of us do not back up until crisis & then it may be too late.
Also use Time Machine. For the 1st time in my computer life, my computer is well backed up--although now realizing the need for redundancy so will start backing up to at least 2 different HDs alternatly.
So, not sure why it isn't working & hopefully you have come up w a solution by now.
I think what I would do in a situation like this, since you can access it on the Windows machine would be to transfer the data to the Windows machine & then transfer it back to a different back up.
I'm looking into backing up what I still have in Windows using a thumb flash drive. I think it should all fit ok now that they have the larger drives & I don't have very much left in Windows format.

Using Mac mini as External Hard Drive for time machine

I know this can be done but I am not sure how. How can I set up a mac mini as an external hard drive. Can this be used as a drive for time machine?? Any help is appreciated, Thank you.

Personal file sharing (which may require Leopard on the Mini) or by connecting the Mini to your other Mac via Target Disk Mode. I wouldn't recommend that latter, though; too much chance of inadvertently erasing files critical to the operation of the Mini.

Mac book pro + external hard drive plus desktop with ethernet router combo

Can anyone advise - for or against / solutions that might be possible as I'm considering time capsule.
Currently
Desktop = Mac Pro - 230GB hard drive no wireless card.
One ethernet port going to router into which my broadband is piped. Out of the router - ethernet to plug in lap top in other room (hubby not so found of wireless).
Back up = 500GB external formac drive (noisy and vibrates) connected via fire wire. All my photos and music go direct to the formac drive (are not on desktop or laptop).
I do backup of documents from desktop to the external hardrive manually.
I have a mac book pro which I access the internet by the the ethernet (but don't think I can file share because of the router which I think just pipes the internet to both computers).
*What I would like to do*
1) Access documents from the desktop vire wireless when working on laptop.
2) Continue to store photos and music without clogging up my desktop hard drive.
3) Get a quieter external hard drive (been noisy since day 1)
4) Easy backup of of photos and music (at the moment only one copy exists on hard drive which I am concerned about (other than DVD).
5) Turn wireless off when not working on laptop - hubby concerned about privacy and I work from home so have confidential material I have to guarentee is secure.
Can any one point me to whether time capsule and or other bits would meet my needs?
Thanks - Lou

1) is doable I use that functionality Even from Pennsylvania to Michigan
2) I use the TC as backup for my primary hard drive although I always use two back up hard drives for my primary. I use the Finder not Time Machine.
3) The LaCie d2 or the quadra work fine with TC. They are quiet and sleep appropriately.
4) is doable and related to your one.
5) secure your router and wireless setup is not a problem.
You can also use the setup of the external to interact with ATV. Like streaming movies to ATV

Access files on mac-mini from external hard drives hooked to PC...

Have two external hard drives hooked up to my PC. I am in the process of daisy-chaining (via firewire cable) from the one external-Hrd-Drv (only one that has firewire input) to my MAC-MINI. APPLE STORE REP says it will pick up BOTH hard dirves (through a "daisy-chain" -like cycle) and that their icons will just pop-up on my mac-mini. So, it's all hooked up and then I clicked over to the mac-mini and there's NOTHING. Both hard-drive icons are no where to be found! There still ONLY found on my PC, of course. Once a again, I was told that my mac-mini would pick-up or access both hard drives from my PC by JUST using a firewire cable! I've done that and I'm having no such luck. Is there a way to do this? Please Help...thanks!

Can you re-state exactly what drives are connected to which computers, and how?
An external hard drive plugged into a PC (or, indeed, even another Mac) on your network will not automatically "show up" on your Mac mini, no matter whether it's USB, Firewire or what. The only way you can even connect to it from the Mini would be to share it out from the PC as an SMB/CIFS (Windows file sharing) share across the network.

Why can't my mac locate an external hard drive?

I'm unable to install yosemite as right at the end of the install (some 3 hours) it states I don't have enough memory. I didn't really think I had that much on it but hey ho. When I connect an external hard drive to me mac it can't find it.
I've tried to book a session at the genius bar but they don't offer appointments for mac users.

I can't see the external drive by pressing command + shift + c in Finder?
It is listed in System Information.app > Hardware > USB?

Is there any way to connect an iPhone to an external hard drive without the use of a computer?

Hello All,
I am planning to travel to Central America, and I want to take pictures with my iPhone. I only have 8 GB memory, so I wanted to take my 1 TB WD Mac External Hard Drive with me on the trip. Is there any way I can connect my iPhone directly to the external hard drive, without the use of a computer? Thanks in advance!

The external hard drive has only one input port which is usb, so you can only use usb here. Also try considering online storage.

Can I boot mac from an external hard drive (internal hard drive hard drive closure)

Model: Macbook Pro 2010 mid
OS: OSX 10.9 Hard Drive: WD5000BPKT 500GB
For some reason I need to change my perfectly working internal bootable drive to external bootable drive.
I took out my internal hard drive, put it into closure, and then connected it to mbp with USB. But my mac cannot even recognize my external hard drive. It displays a folder with a question mark with grey background, which means it cannot find executable boot drive. I tried pressing option key during start up and nothing showed. Also, I tried resetting parameter RAM but still no luck. Any help will be appreciated.

The reason is somehow complicated and most likely be related to the question itself, so I did not write it down. But here is the situation.
I bought a new SSD to update my HDD. I found a software called carbon copy cloner, which could do a bootable clone. I tried to clone my original hard drive to SSD and turned out the SSD only worked when it was connected externally. After I seeking a while, I found a solution from CCC website: do the clone again with putting my original drive externally and the SSD internally (I think it is a bug of CCC.)
You may say, "why not use time machine" instead of using a third party software. My answer is time machine is too slow, and I have to reinstall the OS. My focus is why my internal hard drive does not work externally since it should work.

How to use mac mini as external hard drive

trying to wipe an old mac mini and use as external hard drive for my iMac. Help!

Connect them with a FireWire or Thunderbolt cable and start up the Mac mini with the T key held down. If desired, use the Disk Utility in the /Applications/Utilities/ folder to erase it.

2 Macs sharing an external hard drive, but can't see each other's music

We bought a 300GB Lacie external hard drive, and pointed each Mac's iTunes to the same folder on that drive. Then the computer asked to "consolidate," which means copying all the music on each to that shared folder--which is great so far. But then in iTunes one Mac can only see the music it copied to that folder, and the other can only see the music it copied over. If I go into Finder, I can see both of our music, but in iTunes, no. There is some purchased iTunes music, but mostly just our own CDs.
What happened, and what can I do? Thanks!

Each computer (actually, each user account on each computer) has its own iTunes Library, which is a directory file. Moving computer A's music files to the new hard drive resulted in the Library file being updated to show the new location of the music that already was part of the Library. Moving computer B's files to that same location didn't affect computer A's iTunes Library file.
On each computer, you'll need to use the Add to Library command (or do the equivalent by dragging music folders from the Finder onto the Library icon in the Source panel of iTunes) to get all the music into your Libraries.
If the Copy files to iTunes Music Folder when adding to Library preference is ON (under Advanced\General of iTunes Preferences), then when you add music to your library, those files will be copied to the location in iTunes Music Folder location, if they're not already there. You may want to check these settings to make sure you won't end up with extra copies of music files in locations you hadn't intended.
