External hard drive not working with Time Machine

I have an Iomega network hard drive attached via ethernet cable to my Airport Extreme router.
I plugged the hard drive in. Everything works like it should. I can see the drive in Finder and I can read and write to the drive. I do share the network drive in a mixed WIN and OS X environment. I never had to reformat the drive and I can read/write to the drive with no problems from all of my computers.
I turned on Time Machine on my iMac and walked through the simple setup screens there. I never set anything up on the hard drive through the drive interface software. And Time Machine worked fine for about 4 months. Then all of a sudden, Time Machine just stopped backing up and I got all kinds of error messages saying that the TIme Machine backup failed.
So I went into Time Machine, turned it off, turned it back on. No luck. Same error messages.
So I started fresh. I deleted the prior Time Machine backups and I am back at the TIme Machine set up screen. OS X can see the TIme Machine share on my external hard drive and I tell the setup wizard that's the drive I want to use.
Then I get a window that says it's trying to connect to the external hard drive which I call "Cloud_Drive". After about 30 seconds, I get an error window that says
"There was a problem connecting to the server "Cloud_Drive-TimeMachine"
The server may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again.
At this point the external drive is still visible in FInder and I can read/write to it from my iMac. I just cannot understand why Time Machine was working and then all of a sudden it stopped.
I did go into the software management of the drive and found an area in which to turn Time Machine on on the drive's side. Which I never did before so I turned it on and then I'm prompted to enter the name of the computer and the ethernet ID. I entered the name of the iMac and I have tried using the WiFI MAC address - no luck getting TIme Machine to work and I've also entered Terminal, found a MAC address under the line titled "ether" and still the same result.
I have also changed the destination of the Time Machine files on the external hard drive and the Time Machine wizard does write a sparcebundle file to that new location but still get the same error message above.

Is it a firewire ext. HD?
Yes, many are reporting same, there is a firewire fault and TB HD on external HD from LaCie (Seagate) and from WD especially.
Technicians are looking into it.
Until there is resolution, consider setting up a USB ext. Time machine HD.
Until then consider confining Mavericks use with USB HD.
Ive tested a long line of USB HD on Mavericks, all seem fine.

External hard drive not recognized after time machine locked up

I was backing up to an external hard drive (300GB Western Digital) and time machine locked up. I had to shut down the computer and restart. Now the external hard drive does not show up on the desktop?
I can see it in disk utility but I am not able to mount or unmount the disk, I keep getting an error that the disk is in use. I tried to erase/reformat the disk and no luck.
Any suggestions?
Thanks for the help

Do I need to boot from the install DVD?
this is often the easiest and eliminates any "busy drive" problems. what's wrong with booting from the install DVD? takes a couple of minutes.
My main hard drive is OK... the drive that I am having problems with is an external hard drive that I was using to back up my lap top. I just want to get the external drive reformatted, but disk utility will not erase it. I get an error that disk utility shut down, "please check the drive and make sure that the drive is not in use or programs are still running"
Is their a way to do a hard or forced reformatting of an external hard drive, I don't care about the information on the drive
I also tried disk warrior to recover the info on the disk and all it does is crash my mac pro????
Thanks again for the help

I bought a new external hard drive for backups, but time machine won't do a full back up. I think it is remembering backing up onto previous external hard drives, which I don't own anymore. How do I do a new full backup?

When I bought the new (used) iMac, I also bought an external hard drive for backups. It worked fine, but my husband stole it.
Then I bought a new external hard drive (Seagate) and it worked fine for three weeks, then died.
So I just got a new external hard drive, which was put together from an internal hard drive and a hard drive enclosure.
Time machine did the first backup today, and it should have taken 9 hours like it did on the previous first time full back up. Instead, it took 30 minutes. That can't be right. I want to start over and do a full backup to make sure everything gets onto my new external hard drive, but I can't figure out how to do that. Please help.

Triple-click anywhere in the line below to select it:
tmutil compare -E
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).
The command will take at least a few minutes to run. Eventually some lines of output will appear below what you entered.
Each line that begins with a plus sign (“+”) represents a file that has been added to the source volume since the last snapshot was taken. These files have not been backed up yet.
Each line that begins with an exclamation point (“!”) represents a file that has changed on the source volume. These files have been backed up, but not in their present state.
Each line that begins with a minus sign (“-“) represents a file that has been removed from the source volume.
At the end of the output, you’ll get some lines like the following:
Added:
Removed:
Changed:
These lines show the total amount of data added, removed, or changed on the source(s) since the last snapshot.

What brand external hard drive is best with time machine

what brand of external hard drive works best with time machine?

Contrary to the other two replies, I will relate what I've read here: WD drives are fine, but their (cheap?) enclosures are subject to failure. Some buy a bare WD drive and install it in an Oxford Chip external enclosure (OWC / macsales.com would be one source). And, I have two LaCie Quadras and one OWC Mercury Pro - both are generally recommended here. If you want it bootable, most WD drives do not support it:

Please note: it's good to have an external hard drive which has its own power supply and, as mentioned, FW 800 or USB 3). You also do not need any software that comes on the external - you will most likely need to format it anyway because most come formatted for Windows, but that is easy using Disk Utility.

Can I view photos and movies from my external hard drive? I used Time Machine and a WD Passport for backup. Since my drive on my MacBook Pro is filling up I was planning to delete some of the movies and photos.

Hello, eco1.
Thank you for visiting Apple Support Communities.
This sounds like you are wanting to move your iTunes media folder to an external drive and have iTunes this folder from this location. If this is the case then I would recommend taking a look at the article below.

How do I find my photos on my external hard drive backed up using Time Machine?

How do I find my photos on my external hard drive backed up using Time Machine?
My hard drive died so this is my only storage. The hard drive was from an early 2008 Macbook Pro.
I had recently installed Snow Leopard.

If they’re in an iPhoto library, look in the Pictures folder of your home folder first. Otherwise, they’ll be in the location corresponding to the one you saved them to.

Can i use time capsule for external h drive and also for time machine?

Can i use time capsule for external h drive and also for time machine?

Hello, vascocaco.
If I understand correctly, you're wondering if you can use your Time Capsule's internal hard disk both for Time Machine backups and as an ordinary drive. Is this your question?
You can, but Time Machine backups may take longer.
To do it, you should partition your Time Capsule's hard disk to create one volume for the backups and one for other files.

Partitioning an External 320gb drive for use with Time Machine and...

I want to be able to use my Western Digital 320GB external drive for use with Time Machine and to use as extra storage space on both my Mac and when I boot into Windows Vista.
Is this possible?
I was playing around in Disk Utility and would I partition the part I want to use for Time Machine with the Mac OS Journaled, and whatever I want as space for windows, use a MS - DOS format?
Has anyone done this before?
Cheers-

Unless you are using 64 bit version of MSWindows (64 bit XP/Vista), it won't be able to handle a disk with GUID partition table (GPT). Disks with Apple Partition Map (APM) or GUID partition table are the only ones that Time Machine will work with (not MBR disks). Note also that the MBR/APM/GPT are at the DISK level and not the partition level, so don't mix the format with partitioning scheme. Time Machine disks are meant to live in the Mac universe (for now, anyway) and sharing with the MSWindows 32-bit universe is not possible.

Iomega eGo 2TB USB/Firewire 800 drive not working with Time Machine.

The drive I had for Time Machine died and I replaced it with an iomega eGo 2 TB USB/Firewire 800 drive. Time Machine finds it and backs up the disk when I first boot up but then it seems like the drive goes off line. At that point, when Time Machine tires to back up it can't get the drive to respond and my system hangs. To fix that, I turn off the iomega that fixes the hang up and I get the disconnect without ejecting warning.
I ran disk utility and disk warrior. Both apps reported the disk is fine.
Can any tell me what's up? I'm running OS X 10.7.2
Thanks.

I am having this exact same error with my new iMac 21.5" connected to a brand new Iomega eGo 2 TB Desktop Firewire 800 External Hard Drive (Mac Edition - 34796).
The TimeMachine backup works fine, but as soon as the iMac goes to sleep and wakes back up, TimeMachine doesn't respond well to any commands and all sorts of errors appear on the screen.
I will try the tip here from Kappy and report back later if this works for me.
Kappy, one thing to note is that I'm using the Firewire connection from the iMac to the eGo and experiencing this problem. The eGo has its own power supply too.

My 2010 imac does not recognise my time machine since I had the Seagate replacement hard drive. Any thought from anyone? The External hard drive is a 1 TB seagate

My iMac (2010 intel model) does not recognise or communicate with my external seagate drive as a time machine for back ups since I had the 1TB Seagate replacement hard drive as part of the replacement prgram with OSX LION 10.5.8 installed.
Is this because I need to update the time machine drive itself?

This excellent Support article may help you solve that TM problem:

External hard drive connected and running time machine backups but icon not showing up in finder

My external hard drive has been connected for a couple of years and is using time machine perfectly. i am trying to save my iphoto library on the external drive but the icon is not displayed in finder. Only time machine icon is displayed......thanks for your help!

Did you create a second partition for your iPhoto Library or did you just use the same single partition that TimeMachine is on?

External drive not showing in Time Machine back ups

ok, I have several problems, the first one being the fact that my external drive, where I have all my data, is not mounting or sometimes it mounts but soon dissapears. I was not worried at the beginning since I thought, that is why I have time machine, I have all my files backed up. However, the external drive does not show in any of my back ups. It dissapears from Time Machine too so all my previous back ups from the external drive dissapeared too. I have all those backups before. Any ideas of what is wrong? I have 10.5.8

Thanks a lot. I am sure I am doing somethign wrong but since the external hard drive can not be seen any more, I don't see it either in any one of my back ups. It does not show anywhere.
Also, my external drive gets detected sometimes, I run Repair Disk, it says it is fine, then it works for a while and then it stops working. I need to turn it off, then turn it back on and again it works for a while. I have run disk utility everyt time when the hard drive works and still says it is ok, then it stops working again after a while. Any ideas with either one of these problem ( or both)?
Try other ports and cables. If it has a separate power supply, try plugging-it in to a different outlet. Make sure all the connections are secure. Can you try it on another computer?
Your disk may be failing, or need a firmware update. Check with the maker's website, support and/or forums.

External Hard Drives not recognised

I have a few different external hard drives on which I have stored photos and movies etc. I used to keep them attached and on all the time, but decided some time back it might be better to leave them off until required. I now have OSX 10.5.8 on my Mac Pro and Macbook Pro and neither will recognise my external hard drives. 1 is a LaCie and the other a iOmega.
Have tried a reboot on both machines with the drives switch on, and off, disconnected and re-connected cables, nothing works, they just don't appear!
Any ideas?
Thanks

Maybe the following will help....
Thought you could use this info about getting FireWire to work!
First, you should always Repair Permissions in Disk Utility before and after any update; I would do that now. If you installed your update with FireWire plugged in, your Mac may not recognize it anymore.
Try resetting your FireWire ports by disconnecting all FW devices, shut down your Mac and unplug it from AC power (wall socket) for 30 minutes. plug it back in and try FW.
If that didn't work, download the combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
If that still didn't get it Zap the PRAM. While restarting Mac hold down the following key combo Command-Option-P-R. Keep holding those keys down till you hear the second start-up chime, then release.
For those of you with Macs that are not PowerBooks or iBooks, a bad internal PRAM battery can cause FireWire to not be recognized, so make sure it's good! Also, here is Apple KB HT1317 on getting FireWire to work.
Here's another Fw Faq.
