My external hard drive is not recognized by Time Machine; "The backup disk is not available" according to Disk Utility
I'm not completely tech savvy, but I'm having troubles with my external memory & time machine. I'm a student, and thus its very important to me to be able to back up my computer.
I wanted to back up my Time Machine the other day. I clicked the icon at the top of the page (beside the battery icon, etc.) and the message "The backup disk is not available". I have a 500GB Seagate passport (ie: http://www.bestbuy.com/site/Seagate---FreeAgent-GoFlex-500GB-External-USB-2.0-Po rtable-Hard-Drive---Silver/9929098.p?id=1218196478444&skuId=9929098)
My macbook pro is version 10.7.5 Mac OS X Lion. My external memory is only about a year old. It hasn't been dropped or anything; it permanently sits secured to my desk.
What appears when I click "Repair Disk":
Verify and Repair volume “Time Machine Backups”
Checking file systemChecking Journaled HFS Plus volume.
Detected a case-sensitive volume.
Checking extents overflow file.
Checking catalog file.
Incorrect block count for file shutdown_time
(It should be 1 instead of 0)
Invalid node structure
Rebuilding catalog B-tree.
The volume Time Machine Backups could not be repaired.
Volume repair complete.Updating boot support partitions for the volume as required.Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
After clicking "Repair Disk" this message pops up: "Disk Utility Stopped Repairing 'Time Machine Backups' Disk utility can't repair this disk. Back up as many as your files as possible, reformat the disk, and restore your backed-up files."
I don't want to wipe my memory on my external disk just in case the disk doesn't restore (as I do not have another disk to back up my computer on to).
What is going on? Why is this happening out of the blue? How can I fix this?
Sounds like it either has, or is about to die.
If you don't need anything off the old drive, then yes, replace it immediately with something a little more reolaable. I use WD Caviar Black personally. But anything that has a known low failure rate.

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. -
When ever the power goes out or I restart my iMac the external hard drive that is used for backups by Time Machine is dismounted and all backups are gone. I can reselect it and it will start working again, but I am worried if the iMac hard drive should fail will I be left without a backup ?

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.
Am prompted to reformat but I don't have a good understanding of what this means and how to 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. -
My external hard drive stopped being recognized by Time Machine. Any fix? being recognized
As the title of the question suggests, this happened suddenly, after months of trouble-free integration with Time Machine. If I bring up the disk utility it recognizes the drive, but won't perform any repair or other operations on it. It indicates the disk is unformatted.
Any way to repair/re-format this back-up drive, or should I just toss it and buy another one?Sounds like it either has, or is about to die.

I am trying to get space on an external hard drive which has some old time machine back up files that I do not need but can not eliminate, even by going into the time machine, clicking on the backup file to be eliminated and using the drop down menu with the gear box symbol to eliminate
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. -
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).

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?

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. -
Can you unplug the external hard drive you are using for time machine
can you unplug the external hard drive you are using for time machine and then plug it back in and it work normals because i have a mac book and don't want to always be carrieing the external hard drive every where i go so can you ?
Yes, that will work fine. It will back up normally once you plug it in again. I do this with my MacBook.

WD 1TB external Hard Drive passport not available...
I have a WD 1TB external hard drive and when i plug in the device into my mac book pro it appears as if it is connected but the passport does not display anywhere on my computer. When i try to eject the WD it goes away for a second and comes back up that it is still connected. I do know i have zero space on my external hard dive but i just don't understand how early today it was working and now it can't be found.
Since i have used my external hard dive as my main source for time machine...will i still be able to retrieve my documents, pictures and videos if my hard drive is corrupt? has anyone had this problem before? If so, any suggestions? Thank you!Unfortuanately WD external HD's have a pretty bad reputation with Macs. It has something to do with their enclosures as their internal HD's seem to work just fine. I would recommend exchanging that drive for one with a higher quality enclose. Just about any other manufacturer would be fine however the 3 best IMHO are:
OWC Mercury Elite Pro series
Lacie Quadra d2 series
G-Tech G-Drive series
All have similar features and build quality. I would be comfortable using any of the three but I've been successfully been using the Lacie's for 3+ years.

I have an external hard drive that I have used as Time Machine backup, but not for a while. Now when I plug it in, computer says this disc is not readable.
I want to keep the backups on it and not erase and start over.
Thank you in advance.
GregorIt sounds like something went wrong with the drive. Did you drop it? How long has it been sitting around unused?

My mac mini quit recognizing the external hard drive i am using for time machine.
I have an IOMEGA external hard drive hooked up to my mini for Time Machine. It was working for about 4 months then quit. The PC will not recognize the hard drive and I have switched usb cables and tried different ports to no avail. Any help would be gladly appreciated!!
Yes, that will work fine. It will back up normally once you plug it in again. I do this with my MacBook.

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 ? ThanksThis 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. -
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.
