How can I open up more space on my external hard drive for Time Machine?

I have a 500GB external hard drive that I use with Time Machine. I believe I have half designated for Time Machine and the other half to use as an external drive to put whatever I want on it. My issue is that now my Time Machine back up needs more than 250GB of space.
How can I make more space available on Time Machine and less for the external half (maybe split it 400/100 for example) or just designate the whole 500GB for Time Machine?
Am I going to have to reformat the hard drive? I'm trying to do this in a way that I'm not going to risk losing what might already be on Time Machine...
I'm not sure how well I'm explaining this. Hopefully someone can help.
Amanda

I would also suggest you get a 2nd, much larger hard drive, partition it if desired, move your data to it, and start a 2nd Time Machine backup on it. You can set Time Machine to alternate between the 2 drives by adding the new drive to System Preferences/Time Machine. If you want to make a copy of your current backup on the new drive, you can do that using the Disk Utility Restore tab. If you chose to do that, make the copy first since using the Restore tab erases all data on the drive or the partition.

How can I partition the remaining space on an external hard drive for use in Time Machine?

I backed up files from my old macbook to this external drive. I want to use all remaing space for time machine on my new Air that runs OSX Lion. Please help

It is usually recommended that your keep a clone of your HD and your Time Machine backup on different drives.
You don't want your backup drive to fail and lose both your clone and your TM backup.
The answer to your question is to use Disk Utility to partition your drive. Again, you should have a backup of your drive before you partition it.
Launch Disk Utility, select your external drive > Partition > Resize the partition by sliding the tab at the lower right corner of the image > Create a new partition with the space that has been freed up.

I have just upgraded from a Macbook to a Macbook Air. I have been using a iomega external hard drive for Time Machine, which use a Firewire. However, Macbook Air's do not have a Firewire port and i cannot find an adaptor anywhere. Can anyone help?? Thanks

There has never been a reliable firewire ---> USB adapter suitable for external high speed storage. This was a major issue when the MacBooks lost the firewire port a number of years ago (Apple subsequently brought it back).
The only high speed port on the Air is the ThunderBolt port. There are external ThunderBolt drive options out there, but they're somewhat more expensive than traditional USB/FireWire options.

Can not fine external hard drive for time machine sence lion was installed

I can not fine external hard drive for time machine sence lion was installed, it don't reconise it at all.

I have a Mac Mini (late 2009) and I have an iomega 1TB external hard drive connected to my mini via firewire and usb (usb allows me to use the usb ports on the external 1TB drive to daisy chain other devices). Since I installed Lion, my Time Machine and this 1TB drive (and its partitions) is finicky. Sometimes it is mounted and sometimes it is not. This issue has only surfaced post Snow Leopard and in the Lion era. I am not the first to say this but the whole reason I went Mac was b/c of Vista. I am beginning to think that Lion is the new Vista. Sorry for the latter, just venting... b/c this ain't the first issue with Lion.

Is it possible to use more than one external hard drive for Time Machine backups?

I want to use two hard drives for Time Machine backups.
Bigger one keep at home and be sure it is safe.
Second one (very small pocket size) keep with me for travels.
I want to backup to both drives to be sure I can restore everywhere and to be sure if something bad happened with my small travel disk I can restore from home backup.
Is there any problem with listed schema? Is it normal for Time Machine to handle backups for different drivers and keep everything consistent and smooth?

I really need some help! I have been using an Iomega NAS 1TB HD for the past year. And I received an error message. I believe I have ran out of memory on this drive.
Then recently in the last couple of months I got a ReadyNAS Duo 2TB with 2TB RAID. Should I switch my back ups to this one and delete the other back up file or keep the old back up image file on the Iomega?
Can I transfer the old image back up to this new ReadyNAS? How do I do this?
I appreciate any help.

How can I open Elements 7 Downloader on an External Hard Drive?

Hi there,
Last night I moved perhaps a thousand photos from "My Pictures" on my computer's hard drive to an external hard drive--first time I have done this ever. I have a Toshiba Satellite that is rapidly running out of space. I have Vista Home Premium, and the new hard drive is a 320 GB FreeAgent Go (by Seagate).
When I attach the handsome little red device to my computer via USB port the Adobe Photoshop Downloader appears with 24 folders (3 across, 8 down) but the interface (I think that's the right term) doesn't seem "alive", i.e., I click here-and-there and nothing happens at all.
It seemed to easy last night that I thought something was amiss--now I see I probably botched the operation--alas, something that is the norm for me.
Hope this makes sense, and thank you.

Bill,
1-- what model of Toshiba laptop do you have?
I have a Toshiba Satellite A305-S6872 with a 15.4 "screen and its native or maximum resolution is 1280 x 800 pixels. I can barely see some of the Downloader dialogs on that screen, so I think it is important that we learn more about your laptop.
2 -- you say that you moved photos from My Pictures to the external hard drive
Had you imported these photos to the PSE 7 Organizer BEFORE you moved them to the external drive ?
In other words, when you were using the PSE 7 Organizer BEFORE you moved those photo files to the external drive, did you see thumbnails for these photos in the Organizer? If yes, don't use the Downloader to import them now. There needs to be a different discussion about what you should do.
Paige,
I think that you and I are actually having some similar thoughts about this problem. I returned to the original post here because I thought that using a method of comparing his laptop to mine of the same brand might be helpful. Of course, it would not be necessary to be the same brand, so this is primarily a method of problem analysis.
I keep wondering why the PSE 7 Downloader is appearing when connecting the Seagate external hard drive? On my Toshiba the Seagate external GO drives are being treated as a disk drive and not as a flash drive or camera card reader (where I would expect that the Downloader might launch).
IF these photos were previously imported to the PSE 7 Organizer, then continuing with the Downloader is NOT the correct action. I realize that you understand this. I mention it now so that we do not loose sight of that possibility while we are discussing screen resolution.
Returning back to the topic of screens, I am thinking about the other threads which say that some of the Downloader screens do not fit within the 768 height which is stated as the PSE minimum. So far all the PSE 7 Downloader screens I have experienced fit within my 800 pixel height but some have been so close that I can observe the probability that they don't fit 768.

Can you use the same external hard drive for Time Machine backups and as an additional storage drive?

I have an external HD that I've been using exclusively for Time Machine backups. I need to clear space on my hard drive, so I was thinking to move music & photos to an external drive. Wondering if I can use the same one I have (which I'll aslo keep using for Time Machine) or if I need to get another drive.

Hi Jossydtaylor,
Time Machine can use either an entire external disk or a partition of that disk:
OS X Mountain Lion: Disks you can use with Time Machine
http://support.apple.com/kb/PH11171
You can use Time Machine with a Time Capsule, and with USB, FireWire, and Thunderbolt disks. The backup disk can be directly connected to your computer or be on a network. If the backup disk has been divided into partitions, you can use one of the partitions.
If the disk is partitioned using the Master Boot Record (MBR) partition type, some partitions may not be available for use with Time Machine. The GUID Partition Table (GPT) partition type is recommended.
For more info on partitioning, see this article:
Disk Utility 12.x: Partition a disk

Cheers!

Need to format "free space" of external hard drive for Time Machine

I just recently purchased a MacBook Air and want to set up Time Machine with my external hard drive. I'm migrating from Windows 7 so before purchasing my new Mac, I transferred about 100 GB of data from my PC to my external hard drive that I wanted to keep. The external hard drive has a partition of 100 GB (91 GB used) and 365 GB of "free space". I would like to know how to format that free space so that I can use it with Time Machine but at the same time not lose any of my data on the first partition. I've looked around in the Disk Utility but it doesn't give any options to format the free space.
Thanks in advance for any help.

You should be able to repartition it, but that requires that the HD was formatted with Mac OS X Extended and journaling turned on. All I can suggest is you get another HD or move the 100 GB of stuff to the MBA, erase, reformat, and partition into two pieces, copy the 100 GB stuff back to the HD, and then it's set for TM.

External Hard Drive for Time Machine - 2 TB. Can I remove other external drives it was backing up?

I have an external drive dedicated for Time Machine, it's 2 TB. Last year I started backing up computer (500 GB) and one external hard drive that has 500 GB. IAlso, I have another external drive that is 1 TB connected to my computer. I noticed last week that I was hearing that other external drive sounding funny, so I thought I would add it to Time Machine to back up. Now today my Time Machine failed. I tested the drive or verified the drive and all was well. My thought is because I added this drive to Time Machine it failed because of not enough room? Is there a way to remove that other external hard drive and go back to just the computer and the 500 GB?
I did btw out of a panic mode buy the GDrive that has Thunderbolt with 3 TB, yet I can't use Thunderbolt because that plug is used for my monitor, bummer. But, maybe using this new external drive I can back up the 500, the computer and the 1TB. Any thoughts?

When you say the Time Machine failed, do you mean the drive containing the Time Machine backups failed, or what failed was trying to back up the new drive you added? If Time Machine was able to complete the first full backup of the new drive, then adding Time Machine didn't cause the problem, it was a coincidence. If Time Machine runs out of space it just starts deleting the oldest backup. I suppose it might fail on the first Time Machine run after the initial backup if it didn't have space to delete stuff. When you look at the Time Machine drive in the Finder, is it in fact full? If there's plenty of space left on it, it's not clear what the failure was about.
Also, testing and verifying with Disk Utility will spot some problems but not all.

Thunderbolt can be daisy-chained, so if it or other Thunderbolt devices have a pass-through port it might be possible to do all that. But it might be better to return the drive and get a USB 3 drive instead. It would be fast enough, cheaper, and more versatile. For a single hard drive (not a RAID or SSD), Thunderbolt is not really much faster than USB 3.

Can I use my 2TB Time Capsule ONLY as an external hard drive for Time Machine backups?

Hi...wondering if somebody could help me out there.
I currently have an older Apple 2TB Time Capsule (previous generation) which I'm using as both my WiFi access point, as well as my Time Machine backup location for both my iMac and my MacBook Pro.
We've been having slow WiFi issues in our home, and seeing as how this Time Capsule is a number of years old, were thinking of upgrading to the faster WiFi routers with 802.11ac capability. I'll be honest when I say we were considering other options, beyond the newest Time Capsule.
My question is, can we somehow use the 2TB of storage on our current Time Capsule for the purpose of backing up our computers with Time Machine, but NOT use the WiFi functionality of the Time Capsule itself?
I'm assuming if I manually plugged either my iMac or MacBook Pro (wired ethernet) into the Time Capsule, I could likely get that computer to recognize and use it for Time Machine purposes, but I'd like to use it to backup both computers, ideally wirelessly on the MacBook Pro.
Any help would be great.
Right now I'm running a DSL line into a DSL modem, which then runs ethernet into my Time Capsule. From there, I have a 4 port switch connected for wired devices (we wired our home with ethernet jacks in almost every room). We also have an Airport Express to extend the range of the network.
Thanks,
Jason

You can bridge the TC and plug it into whatever wireless router you buy.
There is no need to turn off the wireless in the TC.. but you can set it up as a secondary wireless network. That is totally up to you. I find the Gen4 TC very fast on 5ghz.. but you need it to be close to the computers.. in your case that should be dead easy.. simply plug it in by ethernet in the same room as the iMac say.. and set it up with bridge and the imac plugged into it by ethernet.. one computer then can access the internet and backup via ethernet with huge speed improvements.. the laptop can then use whatever your new router wireless network.. or the TC one if it is close enough..
So there are plenty of variations and your setup is easy to handle with the large amount of ethernet you have.
Just post again if you need specifics.. but I need specifics to give them!!

Can I use the same external hard drive for time machine and storing other files

I have a 640GB external hard drive that I have been using for over a year for time machine backups. My mac hard drive is now starting to fill up and I am looking to move audio, video and picture files to my external hard drive. How do I do this without messing up my time machine backups? Can I do both on the same external hard drive? Do I just make new folders on the external hard drive to move the files I want? Thanks for the help.

If you move the files you will need to get another disk to back the files up to. You don't want to have only one copy of certain files (personal, professional etc.).

My disk utility option to turn off encryption does not highlight so I can't turn off the encryption of my external hard drive with time machine back up

I have an iMac and Retina MBP. I use Time Capsule for backup of iMac and I wanted to use an external hard drive attached to time capsule as time machine backup. The problem is that I encrypted previously that external hard drive and now Time Capsule does not recognize it.
When I try to turn off encryption with Disk Utility, that option is not highlighted so I cannot use it.
I tried with terminal but it answers The given UUID is a not a CoreStorage Logical Volume UUID

Can you plug in the hard drive directly to your MBP and then decrypt the hard drive? You should be able to do this by opening up Finder and then either right clicking the hard drive (holding down two fingers and clicking) or holding down ctrl and then clicking on the hard drive.

How do i reformat a 'my book' external hard drive for time machine???

i have a 'my book' external hard drive that i would like to reformat to use for time machine -what are the steps to do this? thank you!

Hi alba,
Make sure you don't have anything on the drive you need to keep.
*Open Disk Utility (in Applications > Utilities)
*Select the drive from the list on the left (the line you select should say something like "250 GB WD" followed by some letters and numbers)
*Click on the "Erase" tab
*For the volume format, choose "Mac OS Extended (Journaled)"
*Name it whatever you want
*Click "erase"
That's it! Hope that helps.

How do I Access purple backups from external hard drive for Time Machine

My hard drive crashed and I installed a new one.
Did internet recovery and upgraded to my previous OS.
I am trying to get my data but the backup is purple that I need and I cannot access it.
How do I do this.
Also if I did something wrong, how do I setup Time machine to restore my whole system and set it up so the backups are accessible instead of purple.
Thanks in advance.
I am using Mavericks

Very impressive that it is that easy but trying to get my data is a pain.
Time Machine is a backup of your computer SYSTEM, not idealized as a data archive.
Consider other options for the future >
Data Storage Platforms; their Drawbacks & Advantages
#1. Time Machine / Time Capsule
Drawbacks:
1. Time Machine is not bootable, if your internal drive fails, you cannot access files or boot from TM directly from the dead computer.
2. Time machine is controlled by complex software, and while you can delve into the TM backup database for specific file(s) extraction, this is not ideal or desirable.
3. Time machine can and does have the potential for many error codes in which data corruption can occur and your important backup files may not be saved correctly, at all, or even damaged. This extra link of failure in placing software between your data and its recovery is a point of risk and failure. A HD clone is not subject to these errors.
4. Time machine mirrors your internal HD, in which cases of data corruption, this corruption can immediately spread to the backup as the two are linked. TM is perpetually connected (or often) to your computer, and corruption spread to corruption, without isolation, which TM lacks (usually), migrating errors or corruption is either automatic or extremely easy to unwittingly do.
5. Time Machine does not keep endless copies of changed or deleted data, and you are often not notified when it deletes them; likewise you may accidently delete files off your computer and this accident is mirrored on TM.
6. Restoring from TM is quite time intensive.
7. TM is a backup and not a data archive, and therefore by definition a low-level security of vital/important data.
8. TM working premise is a “black box” backup of OS, APPS, settings, and vital data that nearly 100% of users never verify until an emergency hits or their computers internal SSD or HD that is corrupt or dead and this is an extremely bad working premise on vital data.
9. Given that data created and stored is growing exponentially, the fact that TM operates as a “store-it-all” backup nexus makes TM inherently incapable to easily backup massive amounts of data, nor is doing so a good idea.
10. TM working premise is a backup of a users system and active working data, and NOT massive amounts of static data, yet most users never take this into consideration, making TM a high-risk locus of data “bloat”.
11. TM like all HD-based data is subject to ferromagnetic and mechanical failure.
12. *Level-1 security of your vital data.
Advantages:
1. TM is very easy to use either in automatic mode or in 1-click backups.
2. TM is a perfect novice level simplex backup single-layer security save against internal HD failure or corruption.
3. TM can easily provide a seamless no-gap policy of active data that is often not easily capable in HD clones or HD archives (only if the user is lazy is making data saves).
#2. HD archives
Drawbacks:
1. Like all HD-based data is subject to ferromagnetic and mechanical failure.
2. Unless the user ritually copies working active data to HD external archives, then there is a time-gap of potential missing data; as such users must be proactive in archiving data that is being worked on or recently saved or created.
Advantages:
1. Fills the gap left in a week or 2-week-old HD clone, as an example.
2. Simplex no-software data storage that is isolated and autonomous from the computer (in most cases).
3. HD archives are the best idealized storage source for storing huge and multi-terabytes of data.
4. Best-idealized 1st platform redundancy for data protection.
5. *Perfect primary tier and level-2 security of your vital data.
#3. HD clones (see below for full advantages / drawbacks)
Drawbacks:
1. HD clones can be incrementally updated to hourly or daily, however this is time consuming and HD clones are, often, a week or more old, in which case data between today and the most fresh HD clone can and would be lost (however this gap is filled by use of HD archives listed above or by a TM backup).
2. Like all HD-based data is subject to ferromagnetic and mechanical failure.
Advantages:
1. HD clones are the best, quickest way to get back to 100% full operation in mere seconds.
2. Once a HD clone is created, the creation software (Carbon Copy Cloner or SuperDuper) is no longer needed whatsoever, and unlike TM, which requires complex software for its operational transference of data, a HD clone is its own bootable entity.
3. HD clones are unconnected and isolated from recent corruption.
4. HD clones allow a “portable copy” of your computer that you can likewise connect to another same Mac and have all your APPS and data at hand, which is extremely useful.
5. Rather than, as many users do, thinking of a HD clone as a “complimentary backup” to the use of TM, a HD clone is superior to TM both in ease of returning to 100% quickly, and its autonomous nature; while each has its place, TM can and does fill the gap in, say, a 2 week old clone. As an analogy, the HD clone itself is the brick wall of protection, whereas TM can be thought of as the mortar, which will fill any cracks in data on a week, 2-week, or 1-month old HD clone.
6. Best-idealized 2nd platform redundancy for data protection, and 1st level for system restore of your computers internal HD. (Time machine being 2nd level for system restore of the computer’s internal HD).
7. *Level-2 security of your vital data.
#4. Online archives
Drawbacks:
1. Subject to server failure or due to non-payment of your hosting account, it can be suspended.
2. Subject, due to lack of security on your part, to being attacked and hacked/erased.
Advantages:
1. In case of house fire, etc. your data is safe.
2. In travels, and propagating files to friends and likewise, a mere link by email is all that is needed and no large media needs to be sent across the net.
3. Online archives are the perfect and best-idealized 3rd platform redundancy for data protection.
4. Supremely useful in data isolation from backups and local archives in being online and offsite for long-distance security in isolation.
5. *Level-1.5 security of your vital data.
#5. DVD professional archival media
Drawbacks:
1. DVD single-layer disks are limited to 4.7Gigabytes of data.
2. DVD media are, given rough handling, prone to scratches and light-degradation if not stored correctly.
Advantages:
1. Archival DVD professional blank media is rated for in excess of 100+ years.
2. DVD is not subject to mechanical breakdown.
3. DVD archival media is not subject to ferromagnetic degradation.
4. DVD archival media correctly sleeved and stored is currently a supreme storage method of archiving vital data.
5. DVD media is once written and therefore free of data corruption if the write is correct.
6. DVD media is the perfect ideal for “freezing” and isolating old copies of data for reference in case newer generations of data become corrupted and an older copy is needed to revert to.
7. Best-idealized 4th platform redundancy for data protection.
8. *Level-3 (highest) security of your vital data.
[*Level-4 data security under development as once-written metallic plates and synthetic sapphire and likewise ultra-long-term data storage]

HT201250 Can I share an external hard drive for Time Machine with my PC?

I am using a PC with an external hard drive. I have a new MacBook and would like to back up the files on the external hard drive as well. Time Machine set-up notified me that if I continued my external hard drive would be wiped clean. Is there a way to save the files from my PC and add Time Machine?

Use the DIsk Utility in the /Applications/Utilities/ folder to repartition the drive. The new partition needs to be formatted as Mac OS Extended (Journaled).
If you want to back up the contents of that drive and not use that drive for holding backups, you need to use another backup method, such as drag-copying files or cloning.
