Partition Scheme for Time Machine

I have an external hard drive that is the same size as the internal hard drive in my mac mini, and I want to use the external drive to backup the mac. Currently, my mac is partitioned to use Boot Camp, and I also wanted to use the external drive to share files between OSX and Windows. When I setup Time Machine, will it backup the Windows partition as well? If so, would it be best to setup the partitions on the external drive the same as the internal drive and use something else to share files between OSX and Windows?
Thanks.

No, Time Machine will only backup your OS X partition. You'd need a different backup solution running under Windows to backup that side.

I used a partitioned HDD for time machine, using a partition already containing other data files. I am now no longer able to view that partition in Finder. Disk Utility shows it in grey and "not mounted". Any suggestions of how to access the files?

HDD is a Toshiba 1TB, partitioned into two 500GB partitions.
OS X version 10.9.2

Yes, sharing a TM disk is a bad idea, and disks are cheap enough so that you don't need to.
Now
Have you tried to repair the disk yet

Can I partition my external hard drive so that one partition is for Time Machine and the other is to install Windows with Boot Camp?

I have a Seagate FreeAgent GoFlex 1TB USB 3.0 external hard drive that I currently use just for Time Machine backups. Is it possible for me to go into Disk Utility and create a new partition on the drive so that I may install Windows 7 via Boot Camp? Or since I am already using it for Time Machine do I have to keep it only for Time Machine?

You must install Boot Camp in your internal drive because Windows can't be installed in an external disk and Boot Camp can't do that

Partition size for Time Machine

Just purchased 500 GB Maxtor OneTouch4Plus ex hd and want to set up partition to use TM to backup my 120 GB MacBkPro running Leopard. How big should the partition be for reasonable use?
Thanks for any suggestions!

Hello Pax4us,
3 - 4 times the space that your existing data takes up. Sooooo...
10 Gigs of data on the internal = 40 Gig partition size.
That said, with 500 available - 100 Gig will be OK too.

Is it not recommended to use a partitioned external hard drive for time machine?

1. i hv a 1 tb seagate back up plus hard disc ..,,i want to make partitions for using it for time machine, mac, and window repectively . is it not recommended to use a partitioned drive for time machine? some where i have red that time machine wont be able to restore data from external partioned hard drive in case internal hard drive crashes.
2. if i use the seagate back up plus 1tb for mac only and use time machine to take backup (roughly 250 GB) , then the rest space i cant use to transfer movies, pictures from a PC
3. how should i best use the seagate back up plus hard drive (not seagate back up plus for mac) in a way that i use it for back up , and to work with both mac and PC?

I use a partitioned external drive for Time Machine as well as other things.
How you partition it is a function of yoru needs.

Re-partition external drive for Time Machine

When I originally connected my external drive to my iMac I partitioned it for Time Machine and a media library for my iTunes. I decided to put iTunes back on the main drive to increase space on the external drive for my Time Machine backups. I have deleted the Media partition but the iDisk Utility will not allow me to increase the size of the Time Machine partition. (There is no "drag" graphic/option). Any help would be appreciated. I do not want to lose the backups I currently have on the external drive.

I've gone thru steps from this link I posted in a different forum.

External hard drive partition for Time Machine wont mount

I have an external HD that I've partitioned half for Time Machine, and half for external storage. Today the Time Machine partition wouldn't show up on the desktop. I checked Disk Utility and it recognizes both partitions, but the Time Machine partition is greyed out. When I selected it, in the stat list at the bottom it said "Mount Point: Not Mounted." I then clicked on "Mount" at the top, and after a bit a popup told me it couldn't mount and I should attempt to repar the disk. So I clicked "Repair Disk," and after a while, I finally got the message "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."
Why is only one partition affected? Can I reformat one petition but leave the other untouched? Are there any other options before I do this?
One other item that is probably related: I've been having an issue with a flash drive that seems to constantly unmount itself, giving me "error, disk ejected improperly" messages. Earlier today I believe I had the same thing with my external HD.

Why is only one partition affected?
The drive malfunction that caused the problem only affected that partition.
Can I reformat one petition but leave the other untouched?
Yes.
Are there any other options before I do this?
This is not an option, it's mandatory: start a new backup on another drive. The one you have has lost data once already. If it were mine, it would be in the recycling bin now. You need more than one backup to be safe anyway. Apparently you have no backups at all of the data on the other partition. That means you're going to lose that data, sooner or later.

HT201250 Can I partition my external hard drive and use one partion for time machine and the other one for data that i may want to use in different computers?

I have this doubt. I've just bought an external drive, especifically a Seagate GoFlex Desk 3 tb.
I want to know if it is recomendable to make a partion exclusively for time machine and let another one so I can put there music, photos, videos, etc that I should need to use or copy to another computer.
May half and half, 1.5 tb for time machine and 1.5 tb for data.
I have an internal hard drive of 500 GB (499.25 GB) in my macbook pro.
Any recommendation?

As I said, yes. Be sure your Time Machine partition has at least 1 TB for backups.
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to two (2). Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.

Can I use an empty (NFTS)partition on my 1tb WD drive for Time Machine

I have a 1TB WD external hard drive formatted NTFS into 6 partitons. Can I use one of the partitions for Time Machine? or will it try to destroy all the partitions I have on the NTFS drive? I have Macbook Pro (early 2011 with OXS 10.7 Lion) and am running Parallels with Windows Vista on the Mac. And I have a Toshiba satellite running Vista. I just want to be able to read and write to my USB drive, from both and transfer files from the windows machine to the Mac and vice versa. Any Suggestions?

TimeMachine backups should be at least 2x the size of the HD. Assuming you hve a 500 GB drive, all of the 1 TB will be needed, not just 1 partition.
Even if you decided to run below specs, you still need a disk with the GUID partition mapping scheme and HFS+ partition for TimeMachine.
I just purchased a new/self-powered LaCie 1 TB fro my 500 GB MBP. "New" being the operative word.
As to reading/writing NTFS ... Mac can read read NTFS but not write it without special software.

Partitioning 1.2T External Hard Drive for Time Machine and PC backup?

We have a 1.2T Seagate external hard drive. I partitioned it so that I could use part of it for my Time Machine backups and want to be able to use the rest of it for the PCs in the house. I formatted the rest of the space using the Disc Utility and the MS-DOS option. Was this the wrong choice? I can't use the PC space on the hard drive on my PC. It says there are 0 bytes available.
Help?

no, that was the right choice. I don't know what's going on there. you just might need to reformat the whole drive. also check the partition scheme for the drive. it should be GUID. if it's not GUID repartition the drive with GUID partition scheme.

Can I use the same external hd for time machine and storage without partitioning it?

Hello,
I have been using an external hard drive for my Time Machine that was only used for this purpose.
I downloaded some files in it that I want to use, and I haven't backed up using Time Machine since.
Can I download the files on my MacBook from the HD without running into any problems, or is there anything else I should do?
I prefer not to partition the hd, since I will be deleting these files, or transferring them to a different HD, and using this HD only for Time Machine back ups, as I did previously.
** I am not sure if this changes anything, but I just updated from Snow Leopard to Lion.
Thank you so much

Thanks Kappy, I will do that.
I just really needed these files and had no other hard drive to store them.
Do you think that it will be okay just this one time if I download the files on my MacBook without compromising my backups?
I will transfer them to a new hard drive, and erase them from my Time Machine external hard drive.
For the time being it will be fine. There is always a chance of a disc crashing and therefore not advisable practice. Some here run seperate drives with Time Machine, Cloned backup and file backup. I have a portable drive I keep Time Machine backups and file backups on. I am running that at my own risk, but no problems over the last couple of years. Just make sure I get it to my normal TM Backup disk as soon as I get home. Backing up those other files will not compromise your Time Machine backups as you asked.

I am setting up a time machine backup to a external Hard drive. I want to backup by Mac book Pro running OSX 10.8.5. I would like to Partition the disk and use one partition for Time machine backups and the other for my Lightroom backups. How to do this?

I want to create a two partition disk. One partition for time machine, the other for Lightroom backup. Currently Time Machine is using the entire drive and it is doing the intial encryption and is about 29% complete after two days. I've decided that I want to turn encryption off and partition the disk. So I do I start over?

With the external drive attached, open Finder>Applications>Utilities>Disk Utility. Select the external drive from the list in the left side panel of the DU window. In the main window panel, click Partition in the buttons top center of that panel.
Select the number of partitions you want and adjust their sizes.
For the first partition, click to highlight the partition, then select the format, Mac OS Extended (Journaled) and then the partition table as GUID [both of those are the defaults]. Click Apply and it will ask to confirm and erase and format that partion...oh, give the partition a name, like Backup.
Then repeat those steps for the second partition..and remember to name it...something like Lightroom.
Close Disk Utilitty and you are ready to send TM to the one partition, and do your backup of Lightroom to the second partition.

Do I need to use all the hard drive for time machine or can I partition it

Do I need to use all the hard drive for time machine or can I partition it

You cannot partition a TC disk.
See pondini about mixing data and backups.. but remember this.. the TC has no way to back itself up and TM cannot backup files on the TC. Anything not backed up on the TC will be lost at some future point.

I have a 1TB external hard drive (NTFS) that has all my files from my old PC, how do I create a partition on it for HFS without formatting it so that I can use it for Time Machine and the like?

Can I partition my HD for Time Machine?

Hi all,
I just bought a drive intended for use with Time Machine. However, I would like to know, if its possible to partition the drive first and use only one half for Time Machine?
Another thing, do I have to format the drive to Mac OS Extended journaled first before I can use it? Its a Buffalo DriveStation Turbo USB External HD 500gb.
Thanks

Matt,
I think it's possible that the entire drive might show up as FAT32, but the two partitions (volumes) can be formatted as Mac OS Extended (journaled)....I seem to recall this happening to me when I partitioned a WD 500Gb drive a couple of weeks ago. The Volume is the 'subset' shown just below the Hard Drive in Disk Utility.
Go ahead and partition the drive into two sections. Give each section a name that will be useful to you (perhaps, "Time Machine" for one, and "Data" for the other).
The two volumes should mount on your desktop. If, for some reason, they aren't Mac OS X Extended (Journaled), just use disk utility to erase/reformat them individually as you need.
I'll be off line for about 24 hours. You can't hurt the drive by experimenting with partitioning/formatting it... Just be careful about putting data on it, and then trying to reformat it--you'll lose the data that was on the external HD.
Bob
