I am looking to buy an external hard drive for my maced to time machine.

I am looking an external hard drive for my mac and I do see one in PC world that is compatible with time machine. I do not want it connected to time machine and wonder if I can use it without connecting.

In my view you need to have one external drive connected to Time Machine all the time in order to receive the true benefits it can give. Do not use your internal HD for this purpose.
Having said that, to double up on back ups is a very practical thing to do. I would advise you get a portable HD, say 1TB, from WD or the like, back up your system, disconnect, then top up by connecting it every couple of months or so.
You can then store the portable away from the machine, perhaps with a trusted relative, so adding safe keeping against fire, theft or power disasters

On imac 10.6.8 using current version of Aperture. How can I access the Aperture Library on my external hard drive that I use with time machine for backup? I can only access the application but not the library..

On imac 10.6.8 using current version of Aperture. How can I access the Aperture Library on my external hard drive that I use with time machine for backup? I can only access the application but not the library..

Go into Time Machine (the program not the bundle on the extrnal disk) and using Time Machine's browser go to the Folder where the library lives. You could look in the library bundle in Time Machine but that won't really tell you much,
If you want to make sure it truely has backed up your library you will need to restore it and open the restored library with Aperture.
If all this still has you confused you need to read up on Time Machine in order to get a feel for how it works, for what it is doing and for how to restore files from it.

I cannot find this 300GB "Backup" in the Finder, only in the Storage info when I check "About This Mac".
You are probably using Time Machine to backup your MacBook Pro, right? Then the additional 300 GB could be local Time Machine snapshots. Time Machine will write the hourly backups to the free space on your hard disk, if the backup drive is temporarily not connected. You do not see these local backups in the Finder, and MacOS will delete them, when you make a regular backup to Time Machine, or when you need the space for other data.
See Pondini's page for more explanation: What are Local Snapshots? http://pondini.org/TM/FAQ.html
I have restarted my computer, but the information remains the same. How do I reclaim the use of the 300GB? Why is it showing up as "Backups" when it used to indicate "Photos"? Are my photos safe on the external drive?
You have tested the library on the external drive, and so your photos are save there.
The local TimeMachine snapshot probably now contains a backup of the moved library. Try, if connecting your Time Machine drive will reduce the size of your local Time Machine snapshots.

I have an external hard drive set up as a Time Machine backup on my IMac. I want to add a second external hard drive and put my Aperture Photo Library on it. Is there a way to have the photos on this second hard drive automatically back up to the Time Mac

I have an IMac with an external hard drive set up as a Time Machine for automatic backups. I want to add a second external hard drive and load my Aperture Photo Library on to it so that the library can be shared by both me and my wife. Is there a way to automatically backup the photo library that will be on the second hard drive to the Time Machine hard drive?

HT201250 I have two external hard drives. One is my Time Machine backup drive. The other I use for external storage of files (documents, photos, movies, etc). Can I set Time Machine to backup BOTH my Mac hard drive and my other external hard drive?

I have two external hard drives. One is my Time Machine backup drive. The other I use for external storage of files (documents, photos, movies, etc). Can I set Time Machine to backup BOTH my Mac hard drive and my other external hard drive?

Yes you can make multiple backups on one hard drive, for example if you’ve 1TB hard drive installed in your PC and you’ve two Mac Machines with 500GB drive each then you just make two backup images with size of 500GB each.

Can I switch external hard drives and still access old Time Machine backups?

I have a Mac Book Pro linked to 2 1TB external hard drives, one used as my Time Machine Back up, the other used as a manual ad hoc back up and to store even older files.
The TM back up drive is now full. If I just unplug it/switch it off and plug in and set up a new 2TB hard drive as my TM back up, will I still be able to access the back ups on the original TM drive if necessary, through TM?
Wil it be a start over situation with the new drive, performing a complete back up to begin with?
Or would you advise me to transfer the old back folder to the new drive, given that it will be larger?

Hi den.thed,
Thank you for this - I think the easy option by far appears to be to leave existing backups on disk 1, and plug in disk 2 and start over.

Why is my external hard drive showing up twice on Time Machine?

This is the first time I am using Time Machine because somebody recently gave me an external hard drive.
The external hard drive is appearing twice on Time Machine preferences. One of them is currently backing up and the other one says "Waiting to back up" but I don't want it to back up twice on the same disk.
Here's a screenshot:
Does anyone know why it is doing this?

Triple-click anywhere in the line below to select it:
tmutil destinationinfo
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).
Post any lines of output that appear below what you entered — the text, please, not a screenshot.

I'm looking to buy a external Hard Drive, is Maxtor any good?

I am looking for a external Hard Drive for my Mac Mini, i heard that Lacie is pretty good because it fits right under the Mini but i have never heard of this brand and $130 is a little to much for me right now.
I have found a Maxtor 100GB External USB 2.0 Hard Drive for only $70 but i don't know if Maxtor HD's work with Mac's, should i get WD's My Book HD instead or stick with Maxtor?
EDIT: I Just noticed that the one and only Firewire connection on my Mac Mini is free, is FireWire a better way to go?
Thanks.

I've had my Maxtor external OneTouch 250GB for about 18 months now and it hasn't skipped a beat. I have hear of people having their Maxtor drive just up and die but you will probably find that goes for all manufacturers.
By the way, Maxtor is, amongst others, an OEM supplier to Apple.

I need to buy an external hard drive for my MacBook Air as it is almost full. Which one should I buy?

Do I need to buy an Apple external Hard Drive for my MacBook Air?

There is no such thing as an Apple hard drive, ...Apples doesnt make same.
avoid western digital if possible.
Yes, having an external HD is necessary for data backups and keeping large media files for packing around etc.
you need data redundancy.

Using external hard drive connected to desktop as time machine disk for laptop

I recently purchased an external hard drive for the purpose of backing up my laptop and desktop macs. Both are running Mountain Lion (10.7.5). The desktop is physically connected to both the hard drive and to my modem. I have enabled pretty much every sharing option on both the laptop and desktop. When my router crapped out I began just using the internet sharing capabiilty.
I have been able to chose the desktop as the disk for backing up my laptop, but I want to use the hard drive (connected to the desktop) as the disk. I cant figure out how to do this yet. I can easily access the hard drive by using either the "connect as user" option. I thought that perhaps I could broadcast the connection somehow as an airport connection, but I don't know how to, or if this is even possible.
The desktop is a mac mini, and the laptop is a macbook pro. Both were purchased in mid 2011.

This may assist you:

Western Digital External Hard drive keeps undocking when running time machine.

I have been using a 2TB Western Digital My Book external hard drive for about a year now to run time machine and backup my files. The past month I have noticed that my backups have been failing. I try and for a backup and about halfway through it gets "delayed" because of an error. Then I have a alert pop up on my desktop with the following message:
The disk was not ejected properly. If possible, always eject a disk before unplugging it or turning it off.
The disk was not unplugged from the power supply or the usb port. I am stumped. Anyone know what is going on and how to fix it??

I would avoid WD, Seagate, LaCie, and Iomega external drives, and any drive with special features such as networking or built-in backup software.

External Hard drive not backed up on Time Machine

One of my Seagate external hard drives has failed. I thought that the Time Machine was backing up its contents onto my other external hard drive - I set it to back up everything including the external HD. However I've looked into the Time Machine & gone back to before the HD failed, & there is no sign of it. Surely its contents should have been saved on there even if it has now failed? I don't understand the Time Machine anyway; it seems to only show me certain parts of the computer contents; it's really hard to see all of what is on there.
Second question; what is the best brand of external HD to buy? I thought Seagate was reliable but I no longer trust it after this failure. Someone on this forum recommended OWC Mercury ProElite series?

Thanks all,
This is helpful. I am 100% certain I set it to back up everything except the HD it is backing up onto - I remember specifically telling it to back up the other HD - but strangely, when I open the TM window I cannot see anywhere to specify the folders etc to back up; please see screenshot. All it shows is that the TM back-up drive is excluded. I don't understand where all the preferences have gone? I got this window by clicking 'options'; the only other choice was 'select disk'.
Anyway, if as you say they are not included even if you expressly tell it to back them up, maybe including them has no effect. I will try the shift-command-C thing & see if that helps.
Thanks.

Iomega external hard drive either 'not found' by Time Machine or is now in 'read only' format

I don't know what's going on with my iomega external hard drive. Sometimes the HD is recognised by the computer; other times it isn't; if it isn't I can restore to an earlier back up via Time Machine app; but it's like the disk isn't writable.
Ten days ago, I had trouble backing up my iMac using Time Machine. After turning it off and restarting my external hard drive, it backed up successfully.
However, today I am trying to back up my files, and TM tells me it can't find the external hard drive. Nothing has changed -- I have been out of town this past week -- but somehow my HD now seems to be in 'read only' format. It does turn on, and I could restore my computer to an earlier back up.
"Mac OS X can't repair the disk. You can still open or copy files on the disk, but you can't save changes to files on the disk. Back up the disk and reformat it as soon as you can."
Annoyingly, despite my HD not showing in Finder or on my Desktop (as it usually does), when I simply turn it off I get that warning message "The disk was not ejected properly".
Have tried verifying and repairing using Disk Utility, to no avail.
Am prompted to reformat but I don't have a good understanding of what this means and how to do it. I'm guessing this would wipe the disk clean and I'd have to create the initial back up image all over again -- I'm reluctant to do this since this HD is my only back up and if it all goes tits up I'll be up that famous creek without a paddle.
Thoughts, suggestions, input all welcome and deeply appreciated -- thank you!

It's possible a heavy-duty 3rd-party disk repair app can fix it, but they're expensive (DiskWarrior is about $100), and there's no guarantee it can do it.

That will erase it. See Time Machine - Frequently Asked Question #5.
It sounds very much like the disk is beginning to fail, although it's possible there's a bad port, cable, connection or power supply (if it has its own).
I'd suggest getting a new one, and using it for your Time Machine backups; once you have a good backup there, reformat the old one (and select Security Options to write zeros to the whole drive -- if that fails, you know the drive is toast). Use it for secondary backups, per FAQ #27. If it has failed, get a second new one for secondary backups.

HT201250 Do I need to partition my external hard drive if I'm using Time Machine and other storage?

I never used Time Machine before. I was storing select files on my external hard drive as well as using my libraries (IPhoto, ITune, IMovies) directly off of the external hard drive. That hard drive is giving me problems, so I bought a new one. I want to set up Time Machine on this one, but I also want to keep my active libraries on it. Do I need to partition the external hard drive?

You can partition the new drive, just don't make one of the partitons a TimeMachine drive, save a TM for a entire drive with more space than the boot drive as it saves "states" thus requires more room than most people expect.
I highly advise one drive to one drive for backups, and not placing too many backup eggs in one vulnerable hardware basket basically.
Drives are cheap, data is not. Hardware can fail just as often as software, so you need a multiple backup and storage stragedy to protect even against theft and fire.

Unlocking external hard drive that was locked with time machine

I use a MBP Retina (Mid 2012) with OSX 10.9.4. I left the MBP at Apple for repair and they changed the mother card and reformatted my HD (SSD). Since I had a backup on a WD My Passport external drive I was not too worried to restore. I had clicked the option "password protected" on TM and therefore the external HD was password protected. I also copied pasted many files on the same external hard drive, in case TM would fail one day to operate I thought that I would still have my files ...
But I was very surprised that when I plugged in my external HD into my MBP it didn't recognize it at all. The external HD did not appear on the screen anymore. Nor in Finder. It appeared in Disk Utility but it could not be mounted. Basically it was impossible to access my data. After a while and talking with Apple Support on the phone we could reach a point where a window appeared asking me the password for the access to the HD. Unfortunately it didn't work. The . password was not recognized. Even though we had selected the right country with the icon upper right on the screen to make sure that we used the correct keyboard.
So finally I reinstalled completely the OSX (coming rom Lion all the way to the last OSX) on the MBP and finally I could restore it with my TM. I spent three days on this since it only worked with one OSX - don't remember honestly which one - and not the last one. Don't know why.
Anyway.
Today I have my MPB working but I miss all the files that are still on my external HD because I cannot access to it anymore. As I said the recovery happened all of a sudden with TM with a former OSX and not the 10.9.4. With this current OSX my HD does not appear on the desktop nor on finder. Nothing. It is locked by TM and I cannot even key in the password to unlock it. Useless to say that I have the password.
Any idea how to sort this out please ? Thanks

This might work. Courtesty of V.K.:
run the following terminal commands (copy and paste, please)
sudo chflags 0 /volumes/*
sudo chmod a+rx /volumes/*
you'll have to enter your admin password (which you won't see). that's normal. this should unlock your drives.

I am looking to buy an external hard drive for my maced to time machine.
