I am running my first backup on Time Machine using a Seagate external hard drive with a thunderbolt adapter and cable. I have a MacBook Pro 2011. It is backing up 11GB, and is telling me it will take approx two days. Is this normal?

How can i use time machine using an ordinary external hard drive?

thanks in advance..

Yes. It must be partitioned using GUID and formatted Mac OS Extended, Journaled.
A whole lot about Time Machine for help with TM problems. Also you can select Mac Help from the Finder's Help menu and search for "time machine" to locate articles on how to use TM. See also Mac 101- Time Machine.

I want to take files from my PC (using a Seagate external hard drive) then plug this Seagate External hard drive into my Mac Book Pro and move the files from the Seagate External Hard drive onto my Time Capsule. I do not want to put these files on my Mac

I want to take files from my PC (using a Seagate external hard drive) then plug this Seagate External hard drive into my Mac Book Pro and move the files from the Seagate External Hard drive onto my Time Capsule. I do not want to put these files on my Mac. How do I do this? Where do I put these files on my Time Capsule? Will it affect the functioning of my Time Capsule?

Mixing files with data is not always great idea.
See info here.
Q3 http://pondini.org/TM/Time_Capsule.html
Why not just connect the PC directly to the TC by ethernet and copy the files over?
It is hugely faster and much less mucking around.
In windows load the airport utility for windows.. if you have not already as this will help you access the drive.
There is more info here.

Is there any way to create a time machine backup to an external hard drive with content already on it? I have a hard drive that i have used for pictures but when i try to run a backup it says i need to start from a blank drive. Can i get around it?

It would be much better if you had separate drives for the pictures and Time Machine backups.....but, if you want to use the same drive for both purposes, temporarily move the folder with the pictures to another location for safe storage.
Run the Time Machine backup on the hard drive and verify that everything is working correctly. Time Machine will format the disk for you in Mac OS Extended (Journaled) as part of the backup process.
Then move the folder with the pictures back to the hard drive with the Time Machine backups.
When you have tested to make sure that everything is working again, then and only then should you delete the folder with pictures from the temporary storage area.
Again....it would be much better to keep Time Machine backups on a drive just for that purpose, and other data on another drive for that purpose. This is clearly one of those times when the fact that you can do something does not mean to imply that you should do it.

I got a macbook pro 2008 and can not back up using time machine. it eject my external hard drive everytime. does someone has a fix???

Does your external hard drive have it's own power supply? It should.
Is your external hard drive formatted with the NTFS file system? It won't work.
It needs to be formatted either with Mac OS Extended or FAT32.
(There are drivers available to add NTFS support to OS X but their quality is unknown, especially the "free" ones.)

Time Machine: Can I use a smaller external hard drive with larger internal?

Can I use a 250G external hard drive with and 500G unfilled internal drive with time machine? Or will time machine require I a 500G? I don't plan on filling the internal drive for a long time and don't want to buy a new external drive right now.

Yes, but you are very likely to get in trouble very quickly.
The problem is that TimeMachine saves multiple versions of any file modified, and if that file happens to be large, you can quickly fill up your TimeMachine drive such that it is throwing away older versions faster than you would desire.
Also if your boot drive's storage usage gets even close to the 250GB external drive's capacity, TimeMachine is likely to stop working.
If possible, I would suggest an external drive that is twice as large as your boot drive, or at least 1.5 times larger.
I guess you could repartition your boot drive so it is smaller than your external disk so you would be less likely to use more space than could fit on the external.
Personally, my opinion about backups is that much of my data is impossible to replace (family pictures, etc...), and spending money on backup hardware is a small price to pay for securing those memories. I also try to have it backup in more than one location in more than one way.

I have a seagate external hard drive with files copied from windows pc. If I will download NTFS driver from seagate to my mac, could I install it safely without harming my files in the external hard drive? I am afraid I may erase all files in there.

Thanks a lot! I have already downloaded Paragon Driver and it works well with seagate external hard drive. I am copying as of now my important files from my mac to it. However, I have only the trial version which will expire in 10 days. I don't have credit card to buy for it.

HT1329 My large iTunes library is on an external hard drive. Can I set up iTunes on my new Macbook Pro and copy the library to it or are there any pitfalls?

I have my large iTunes library on an external hard drive. Can I set up ITunes on my new Macbook Pro and transfer/copy this library to the internal hard drive or are there any problems I should be aware of?

ITs an old Iomega 100gb external HD that has about 90gb of music on it. The Macbook has a 500gb HD. I would like to put the iTunes library on the internal HD so I have room to expand.
Phil0124 wrote:

The only thing you do not want to do is over-stuff the internal hard drive. The OS needs some space to operate correctly, so if your iTunes library uses up more than say 80 to 85% of the internal HD's available space it may not be a good idea to transfer it over.
With that said, the internal HD will provide slightly faster access to the library than the external would, but other than that, you can point iTunes to the external drive just fine.

Time machine doesn't see external hard drive on network

I have a pair of external hard drives connected to my iMac, which is connected to my 2WIRE modem/router via Ethernet. I'm using one of them as a Time Machine drive. For the past couple years, I've been backing up the laptops in the house to that Time Machine drive without fail.
Now none of the laptops (a MacBook and an iBook) won't see either external drive connected to the iMac, even though the iMac has file sharing turned on (as it always has) and both laptops are connected to the iMac via the Finder. Both laptops can see the iMac and the external drives connected to it via the Finder, but in Time Machine, when I try to select my Time Machine drive, nothing appears in the window.
I was having a problem with the Time Machine drive and had to wipe and reformat it, but I don't understand why Time Machine won't see the other external drive either, even if there is a problem with the TM drive. I recall Time Machine picking up all available hard drives as possible backup destinations, as long as they're also seen in the Finder.
The iMac has been having some OS X issues. The Finder will crash sometimes, and I have no choice but to hold down the power button to shut it down and then start it up. When it starts, it takes longer than it normally does, I assume because it's checking and/or fixing some things. However, those issues have been going on for a long time (I think I need to reinstall OS X in it, since Disk Utility finds nothing wrong; also, the hard drive in the iMac crashed about 2 months ago and I put a new one in; I then restored the TM backup to it, and the OS X issues have persisted, which tells me it's software-related, not the drive).
Also, the iMac backs up to the Time Machine drive just fine. Of course, the TM drive is connected to it locally, whereas the laptops have to get to that drive via wireless file sharing.
I did try plugging one of the external hard drives on the iMac into my MacBook, and Time Machine saw it immediately, so my guess is the issue must lie with my router and/or the iMac, but I don't know what to check next. I've restarted the iMac, I've restarted the laptops, I've turned TM on and off on the laptops, and I've turned file sharing on and off on the iMac; none of those things reestablished the connection.
I suppose I could just go with external hard drives for the laptops, but my wife moves her iBook all over the house, so I know hers won't get backed up regularly. That was the nice thing about the system I had in place, which I realize wasn't as elegant as a Time Capsule.
Any advice is appreciated. Thanks.

That should say "Now none of the laptops (a MacBook and an iBook) will see either external drive..." I hate typos.
Anyway, after rereading my post, I'm starting to think I just need to reinstall OS X on the iMac, given the other issues it's experiencing. Any advice for doing that would be appreciated, if that's indeed the solution. Thanks.

Time machine doesn't recognize external hard drive

Recently I went to the apple store to get help to switch from Mavericks to Mountain Lion (I had some problems with Mavericks). They used time machine to bring back my applications (from my external hard drive, LaCie) on the Mountain Liion software. They said my time machine/external hard drive should work the same when I got home. Now, when I go to back up my computer, time machine doesn't recognize that I've backed up my files before. In the past, when time machine was working, every time I plugged in my hard drive the icon for it would turn blue, time machine recognized it, and it would back up my files. Now, the icon for the hard drive shows up, but time machine doesn't recognize it.
Some other things:
- when I open my external hard drive on finder, it shows all of my previous back ups
- I used disk utility to check my hard drive and macintosh HD - both are OK
How can I use time machine to continue backing up files? Or am I going to have to partition or erase the hard drive and start a new back up?
Thank you in advance

nevermind! time machine suddenly recognized the disk after half an hour. sorry, I don't know how to delete this post!

Will Time Machine delete files on external hard drive?

I have all my itunes music and videos on my external hard drive. Will Time Machine delete these files. The hard drive is already formatted for mac.

Note from Time Machine Help files:
Time Machine works best if you use your backup disk only for Time Machine backups. If you keep files on your backup disk, Time Machine won’t back up those files, and the space available for Time Machine backups will be reduced.
So it will not overwrite the files but it also will not back them up.

Time Machine Backup Interrupted. Im using a Sony External Hard drive

i have a white macbook, version 10.6.8. I wanted to back up my mac so i connected my Sony External Hard Drive and used time machine. About a quarter way through the back up, i get this message saying to "You need to restart your computor. Hold down the power button until it turns off, then press the power button again." I cannot press/move the mouse in anyway or do anything when this message comes up. When i open my mac again a window comes up saying "You shut down your laptop because of probelm". The backup stops and fails. This has happened 3 times now and has never happened until i tried to back up . What seems to be the problem and what should i do to fix it?

Hi. This is called a kernel panic. You should make sure your software is updated, including any third party software you have. Keep in mind any software you may have recently installed. You may have to erase any files that installed in the backup drive as they could be corrupted. Read this. http://support.apple.com/en-us/TS3742

Time Machine once worked, now external hard drive is "read only"

I have a 2005 iMac G5, running OS X 10.5. Had some power issues, and reinstalled (and archived) my OS a couple of time.
Recently purchased Western Digital 1TB external hard drive for back up. It worked once or twice, but now shows "read only" status.
Disk Utility won't do anything, because it's read only (can't repair, erase, partition or convert).
Hard drive works on PC running Windows 7, and newer Mac with Snow Leopard, just not the one computer I need it for. Any suggestions?

What to do if Time Machine reports you don't have permission
This was posted in the Apple Discussions by V.K. I have only modified it slightly to be more generic.
The problem seems to be that 10.5.6 changes permissions on a file so that even the root user doesn't have write peivileges. I have no idea why they did this. The workaround suggested in [an]other post will probably work, too, but i did something less drastic. Instead of deleting the file I changed permissions on it, and it worked just fine. An added benefit is that the permission change seems to stick, so you don't have to delete the file every time you change a drive.
[Open the Terminal application in your Utilities folder. At the prompt [enter] the following command:
sudo chmod 644 /volumes/"TM drive name"/.xxxxxxxxxxxx
The name of the file .xxxxxxxxxxxx is based on the MAC address of your computer and will be different for every computer. Put the name of the TM drive in the above and keep the quotes.
You'll have to enter your admin password (which you won't see) which is normal.

Time machine, finder save to external hard drive problems

I have a new 2.26 GHz mini and I wanted to get bootcamp going and install windows xp. The instructions suggested to backup the hard drive and I thought this is a great time to try the time machine. I plugged in a external hard drive, opened time machine (Time machine said it needed 29 GB for full backup and the drive had 32 GB free), selected the drive, and let the "backup count down(I think it was a minute and a half)" run down to zero. Time machine started backing up the my main drive to the external drive no problem. It was running good (100MB in 5-10 seconds) for a little while when I noticed that it had reached 2.3 GB and was not going any higher. I let it stay like that for about 5 minutes thinking that maybe it would start going again. No luck. I shut down time machine and saw a finder window with the progress bar behind it saying 2.3 GB. I push the stop button and it said stopping, but it would not stop and disappear like it should. I relaunch the finder and the icons on the desktop disappeared and would not come back. I relaunched repeatedly but they would not come back. Since the bar at the top of the screen would not come back I had to hold in the power button to shut down the computer.
Upon restart everything seemed to work fine until I tried time machine again and it would not work. So I tried to manually backup the files to the external drive. When I copied some files the little finder window popped up and said, zero KB of 290 MB, and would not change. I left it running while opened a browser and did a search for an answer to my problems. After about a half an hour I went back and saw that some files had been transferred. When I looked in the Activity monitor, I saw it was saving the files very slowly. I went to the finder progress bar and when I hit the stop button, it would say stopping but it wouldn't. I would have to relaunch the finder to make it stop. Then I tried to copy the files to a shared drive on my network and the same thing happens.
Before using the time machine both these drives worked no problems. I went to the shared drive computer and used that machine to copy the files from the mini. All files transferred no problems. So now I'm trying to find out what is wrong with my mini. It seems that it has to do with the finder since it effects both the usb and ethernet hard drives. All other functions work as they should. I don't know if anyone has had this problem after using time machine but any help would be appreciated.
Also I tried deleting my com.apple.finder.plist and relaunch the finder. No change.

That's much too small for your backups. Time Machine usually needs 2-3 times the space of the data it's backing-up (see #1 in the Frequently Asked Questions *User Tip,* also at the top of this forum).

That sounds like the drive is not formatted properly. See #C1 in the Start with the Time Machine - Troubleshooting *User Tip,* also at the top of this forum.
The other problems may have the same cause.
Most likely, it's set up for Windoze and not suitable for Time Machine. With only 32 GB free, you must have other data on the drive, so you probably can't erase it and reformat it for Time Machine.
Report back with your findings for the *Partition Map Scheme* and Format of the drive (per #C1), and we can figure out what to do next.

Inherit Time Machine History on Reformatted External Hard Drive?

A few days ago the external hard drive I use to store all my data got corrupted. This external drive is also the location of my home folder (I moved it off the primary disk to have more space). The main OS system disk is fine and I was able to login to the guest account, but couldn't log in to my primary account since the drive wasn't working properly.
From the guest account I ran disk utility on the external drive and it was unable to fix it and it required reformatting. I reformatted the drive and restored the data to it from the my Time Machine backup. I then was able to log back in to my primary account. As far as I can tell all my files are there. However now when I open Time Machine there is no history.
Based on other info I've found on these forums and others, by reformatting the drive (even with the same name), Time Machine treats this as a new drive and wants to start a new Time Machine history for it. I've learned about the inherit history commands that I can run but before I do that I had a couple questions:
1. If the history is still available, should I be able to see that when I manually browse the contents of the Time Machine drive? There is a folder with a "full sized" backup but I don't see any subfolders with incremental backups.
2. If the command fails to link history, is there an alternative to get it back - or should I just format the Time Machine drive and start a new full backup. It seems like everything restored ok, but I'm nervous about reformatting the backup.
3. Might there be a better configuration for my home folder storage for day to day use and backup purposes? With this issue, it was unsettling being effectively locked out of the machine since the home folder is on the external drive. Also it seemed doing a "system" restore could only restore the system drive and not the "complete system" including the external drive. It would be nice if I could just restore everything from Time Machine in one shot without having to shuffle things around, reformat manually etc.
I'm running Mavericks on a Mac Mini if that helps. My external drive is 2TB with about 1.25TB of data currently and my Time Machine disk is 1.5TB. System disk is 1TB.
Thanks!

Your best option is to start another backup on a new hard drive. You should do that anyway, as one backup is not enough to be safe. Put the old drive aside until you're sure you'll no longer need the data on it, then erase it and start over.
