Time Machine Hard Drive for other uses other than backups

I use a WD My Studio II, 2 TB Hard Drive.
Time machine uses the drive as its backup drive, but since the the drive is so big I would like to use it as a general hard drive too. In other words, on a single hard drive, can I have Time Machine backing up my Macbook, as well as use the remaining space to store general stuff that is to big for my mackbook.
The may seem a little illogical, but bare in mind I have the RAID 1 setting, so the one drive is automatically backed up onto the 2nd 1TB drive.
I hope this makes sense, and I hope someone has an answer.
Regards

you might want to consider partitioning your drive, one for TM backups and one for other stuff.

  • Time machine hard drive for transfering files from 2010 MBP to rMBP

    Hello!
    I have a couple of questions here!
    I will be getting the rMBP in the next few weeks so want to do a bit of housekeeping before transferring across.
    1) What is the best way to clear my current MBP of files and applications that i dont use and are just taking up space? I currently have a 256GB hard drive with 8GB free - there should be no reason for this as my large audio/ Raw photo/ video editing files are on an external hard drive. So i think there must be a lot of flotsam and jetsam on there that needs to be removed as i don't want to carry that from computer to computer!
    2) Is Time machine the best option for this kind of service?
    3) Can anyone recommend an external hard drive for the job? I don't want to rely on thunderbolt ones at the moment so would it just be any usb hard drive seeing as Apple has sodded of firewire?
    Cheers
    K*

    OK, I'll bite:
    1) you can just delete the documents that you don't use by throwing them in the Trash. To delete apps and all associated files (and some will disagree with me or suggest another application) I recommend using AppDelete. I believe it's $13 or so but I have used AppZapper and AppCleaner as well but find that AppDelete finds all associated files.
    2) After you've rid yourself of your 'junk' files, I recommend using Time Machine on a dedicated or partitioned hard drive for backups. When you get your new machine, you can just use Time Machine to restore all of your settings, apps, documents, etc. For everything you ever wanted to know about Time Machine, see  http://pondini.org/TM/FAQ.html.
    3) A USB drive is definitely the way to go. I would recommend the G-Drive series from Hitachi here. They have all sorts of connections, including USB 2.0 and Firewire 800. When Apple (finally) releases their Thunderbolt>FW800 adapter, you'll be ready. Others might recommend USB 3.0 drives for the speed but I've seen too many posts of, in particular, Western Digital USB 3.0 drives that have problems with the 2012 Macs to go the USB 3.0 route right now. Maybe someone will jump in and recommend a USB 3.0 drive that they actually have working on a 2012 MBP?
    Good luck,

  • Can I clone my Time Machine hard drive, to another HD, and store Off Site?

    Good day All, I love my new Macbook, but am trying to come up with a foolproof method of backing up all my data, documents, and business.
    I have become very nervous about BACKUPS, and want to have an OFF-SITE week old backup done on a external Hard Drive?
    I presently have a 200 gig Time Machine backup/archive, and have a daily clone with Super Duper & Carbon Copy Clone. However these hard drives are at home, so should the building burn down, or should we get broken into, there goes my business and digital life.
    My thought is to buy an external hard drive and clone my current Time Machine hard drive to the external on a weekly basis, and store it off-site or at a friends house.
    Would I be able to do a clone of my TM HD archive, and have it still useable / bootable / recoverable should a tragedy happen?
    I would like to upload it all up to Mozy, or BackBlaze, or similar offering, but 200 gig is way too big.
    Is anybody cloning a Time Machine hard drive and able to restore from it?
    Thanks for reading my post, and am lookin forward to all of your comments, IAN...

    Hi Ian,
    Sorry I missed the discussion last night. I'll tell you how I'm accomplishing the backup task and you can let me know if this is what you're trying to do.
    I now have 2 external HDs. A 1TB Seagate and a 250 GB LaCie. The LaCie used to be my TM backup drive, but it was the same size as my internal iMac drive. I knew I'd eventually need a bigger drive so I bought the 1TB Seagate yesterday and cloned the LaCie drive onto it using SuperDuper. The only thing on the LaCie drive was TM backups. Now the TM backup are on the Seagate. I unmounted the old TM drive and changed the name of the new drive to "Time Machine". I activated TM and it picked right up where it left off. I did test it by restoring an old file. I also changed a current file and made sure TM was still operating as advertised. Everything worked as expected.
    Now I simply used the 250 GB drive to clone my system HD using CCC. It is a bootable backup and can be used to run the system should my internal drive become unusable. I will update this drive once a month with any changes to the system drive using CCC and keep it off-site in a safe deposit box in the meantime. Using this methodology, I don't see why you'd want to swap the drives weekly/monthly. Just let TM run on the large drive and keep the other drive as current as you like. I've decided monthly is good for me. I'm mostly worried about photos, but I keep them on the camera longer than a month, so there's my cover for the month.

  • If I add another profile, will that person's content automatically be saved to my Time Machine hard drive or do I need to take further action to ensure that this is saved?

    Time Machine creates a back up of the entire Hard Drive, with the exception of Boot Camp or exceptions you have created. So in other words after you create the profile run Time Machine, and a backup of the other user profile will be added to your Time Machine backups.

  • Erasing Time Machine hard drive after formatting for both PPC and Intel

    Ok, I made a mistake. First I formatted a Western Digital 500 gig hard drive for both my wife's PPC G4 laptop and my own Intel MBP laptop, so we could both use Leopard's Time Machine for backing up to the same drive. That wasn't my mistake though, it's been working fine. I formatted my partition using the GUID option and hers using the Apple Partition Map option (I think that's what they are called, I'm going from memory).
    Here's my mistake: I needed some extra space to store some files and read that I could Re-Partition the drive without erasing anything using Disk Utility. Sounded great. I first tried to partition my wife's partition, since she had more extra space, but then I realized that was a bad idea since I had formatted her partition with using the Apple Partition Map, so I stopped and then tried to Re-Partition my side. It worked for about an hour: my Time Machine backup drive appeared, my new partition appeared, but then... her partition disappeared! Usually whenever one of us plugs in the hard drive using the firewire cable, both partitions appear, Time Machine Goes to work, and that's that. When we need to disconnect from the drive we have to eject both drives, but no big deal. Now her drive isn't appearing.
    So... I tried to repair it, no good. Tried to erase both her partition and mine (to just start over): no good. I can't do anything to either of these partitions now, from either computer. Tried everything I could think of in Disk Utility, from both computers. Won't erase, won't re-partition. Not a hardware issue: it all started when I did this stupid Re-Partition. Help!!!!
    I want to erase the drive and start over. Can anyone advise??

    Jasonmo,
    First, let's talk about the various partition schemes. A partition scheme applies to the entire drive. Specifically, these are different maps written to the drive, within which volumes are created. As such, this is an either/or thing; your drive is partitioned using either the GUID Scheme, or the Apple Scheme, not both.
    "Live" partitioning or re-sizing of existing volumes is supported only under the GUID Partition Scheme. If the drive wasn't using this scheme, you would not be able to re-size as you were attempting to do. Even re-sizing under the GUID scheme requires that the drive's maps and directory structures be in very good shape, if it is to work without hitch.
    Are you absolutely certain that there isn't some physical problem with the drive, or with its interface (cables and such)? If it is operating normally, you should be able to re-partition it without problems. In DIsk Utility, select the drive (not a named volume that will appear indented underneath), then click the "Partition" tab. If you wish to be able to re-size volumes later, you must choose the GUID scheme from the "Options..." dialogue sheet. Set appropriate sizes for the volumes, then click "Apply." Doing so will destroy all current volumes and data on the drive.

  • Time Machine hard drive is not sleeping.

    I have been using a 1TB Maxtor Basics (Seagate?) external USB hard drive for Time Machine on my iMac for over a year now without any problems, until recently. Between backups, the Time Machine HD does not go to sleep anymore. I am certain that until recently it would automatically go to sleep between backups and wake itself for each scheduled hourly backup. The USB HD is now running constantly when the iMac is awake. Has anyone else had this issue? Can anyone confirm that their "Time Machine" does in fact sleep between backups?

    Hey Pondini. It appears my Internal HD is not sleeping either.
    Since you've already replaced the preferences file (the first suspect), there may be something using both disks. If you're running any anti-virus software, turn it off (or uninstall it). Exclude both from Spotlight Indexing, if you haven't already, via +System Preferences > Spotlight > Privacy.+
    If that doesn't help, use the +Activity Monitor+ app (in your Applications/Utilities folder), to see what's running. When it starts, select either +All Processes+ or +Active Processes+ in the toolbar, and sort the list by the +% CPU+ column, so the highest numbers are on top, and select the CPU tab towards the bottom. Some system processes run more or less continually, so it's not easy to see what's using the disk(s), but you may find something. If the process(es) involved aren't familiar to you, post their names here (and/or check this out: http://triviaware.com/macprocess/all)
    I would like to do an "Erase and Instal"
    That's extreeeeeeeemly unlikely to change anything, unless you have some software that you loaded for the Maxtor (if so, just delete it and Restart).
    As another poster (Kiraly, I think) says, that's like fixing a dripping faucet by tearing out the kitchen!
    but although I know my Documents are backed-up, where are the other things like all my emails and stickies, favourites, notes etc. filed?
    What are you contemplating? Erasing your HD, installing OSX, applying the "combo," and selectively restoring things? If so, that's a large project, with very little chance of success.
    First, make a second full backup on a separate external HD, via the Restore tab of Disk Utility, CarbonCopyCloner, SuperDuper, or the like. It's rare, but on occasion a backup drive fails during a restore, and everything is lost.
    Then, here's what you'd be looking at:

  • Time machine & hard drive errors

    I'm using Time Machine to back up my OpSys hard drive to an external USB connected hard drive.
    It will run without a problem for a week, or two weeks, maybe even a month before I get a message telling me the backup failed because (a) could not read from the external drive (b) could not write to the external drive. I'm told to run disk repair and when I do I am told it cannot be repaired. It is always an invalid node value. Something like the node should be 4067 but is 125429461.
    Erasing the USB connected disk and starting over seems to work better if I first erase the disk using data protection (write 0s across the entire drive). I've never seen an error when performing the protected erase.
    *Is the partition / format / erase utility capable of producing an error message if the hard drive has problems?*
    After the erase of the drive Time Machine will usually be able to run back ups normally for a week, two weeks, maybe a month, before I get another error (bad NODE).
    I also used another hard drive in the external USB enclosure and encountered similar problems before switching to another hard drive which is three years old but until recently was rarely powered up.
    After searching for tools which would allow me to perform a diagnostic on the hard drive I have come up empty. This hard drive has not been used extensively. It spent most of the first three years of it's life powered down in a external USB enclosure, thus I am reluctant to assume the hard drive is failing, but anything is possible.
    I did recently have this hard drive installed internally for a short time and never saw an error message when it was in use.
    I'm beginning to form the opinion Time Machine might be the source of the problem, perhaps a bug in it's process. I have noted some other people posting opinions that Time Machine isn't very reliable in other internet forums.
    While I could buy a new hard drive and see if that solves the problem, I thought I would see if anyone here has any useful feedback.
    Another possibility is the USB enclosure is the source of the problem. An intermittent failure of some kind within the enclosure could easily make solving this very challenging.
    I'm very interested to read any and all feedback,
    Thank you,
    ~ Allen

    Hi, and welcome to the forums.
    It's unlikely a Time Machine problem; Time Machine uses the normal OSX facilities to read & write, they're the ones that actually manage the +file structure.+ Time Machine does use a complex and somewhat unusual file structure, though, including a huge number of hard links (sort of like aliases).
    You're probably right that it's somewhere in the chain of port, cable, enclosure, and drive. So try different ports, cables, and combinations of the two (a plug that works fine in one port may not make good contact in another). If that doesn't help, it's probably the enclosure or drive.

  • Time machine hard drive going nuts at 2 AM

    I have been using Leopard with Time Machine since Friday. I use a 1TB lacie firewire 800 drive. It has been working well. I happened to be awake at about 2 AM this morning when the drive was spinning continuously without rest despite the TP system preference showing the next backup was schedule for 3 AM. At this time (10 AM) the drive is quiet. Does time machine do some housekeeping daily at 2 AM?

    Right now there's no positive reason to have a Spotlight index on the drive and every reason not to--using Spotlight to find the backup and then restoring it puts the restored copy into the backup, which isn't very useful.
    It's becoming rather clear that Time Machine wasn't ready for prime time... A real pity in that many of us went with Leopard because of it.

  • Partitioning Hard drive for Windows Use

    Hopefully someone has the solution to this.
    I have been trying to partition part of my hard drive for the past couple of days because there is a program I need for a class I am taking that only works in Windows. Every time I try to partition a portion of the drive, it tells me some files couldn't be moved. It also tells me to format the drive and restore it. I am willing to do this, but the instructions on using the disk utility that it gives me do not work.
    I would be most willing to use the systems disk to repair anything I need to or just re-install, but I have misplaced those disk.
    How do I go about replacing these disk?
    Also, is there another way to partition part of this drive?
    It is my internal drive that was installed in the laptop.
    Thank you so much for taking the time to read this!

    You can reformat your hard drive with a snow leopard disk, which maybe a friend has or you can buy one for something like $30.00? Then your mac would be wiped clean as you know.. I have seen this problem before when installing windows on a mac and don't know what causes it. I reformatted my mac and then installed windows fine. Other times I have installed windows it went perfectly fine.

    Hi there
    I would like to transfer my iTunes library from my PC to my MacBook Air or if possible to an external hard drive that I use to back up my Air.
    I understand that you can't use the same hard drive for PC and Mac.
    Would really like to do away with the PC and sync the iPod to the Air.
    Am about to purchase a new iPod nano as my Classic is broken.
    Would appreciate any feedback please!!

    You can't write to it because it's formatted as NTFS which OS X will read but not write to. If you want to continue using the drive with both a PC and OS X you will need to download and install NTFS-3G so you can then write to it from your Mac. You can get NTFS-3G at:
    http://www.macupdate.com/app/mac/24481/ntfs-3g
    If you want to use the drive exclusively with your Mac then move the data off it and reformat it in Disk Utility (Applications - Utilities - Disk Utilities) as Mac OS Extended (Journaled.)

  • Time Machine Hard Drive will never enter sleep mode or stop spinning

    Hi, I'm just wondering if anyone could help me.
    When i recieved my MacBook I took the 80gb hard drive out, and placed it in an external USB drive case to use as my backup device, and placed a 120gb drive into the MacBook.
    Now when I'm using this drive, it never stops spinning when not in use, and when the MacBook goes to sleep, it still continues to spin, even the light continues to flash whilst the MacBook is sleeping.
    Is this because I've bought a naffy external case (it only cost £5 from ebay, it's not even branded with a manufacturers name), or will there be some settings somewhere?
    Thanks guys,
    Seb

    p.s. the external drive case is a SATA-Drive case, self powered by the USB 2 connection, there is no external power involved.

  • Can I use my time machine hard drive to transfer files to a pc?

    Hello everyone.
    I recently broke my macbook, and had to replace it with a pc laptop. I have my data saved on a time machine enabled external hard drive.
    How can I use that hard drive to put my files (music/word documents) to the pc?
    Any information would be greatly appreciated.

    Sadly, in your case, the TM backup is practically useless. TM provides a backup primarily for the machine to which it is connected, and then, only through the TM interface engine, never directly.
    The files are not stored in a linear manner as would be in a regular backup - they are linked to each other and each "file" only represents a "delta" or incremental backup unit. The TM engine knows how to reconnect all the links to create the proper file.
    What you need to do is get another Macbook similar to yours, and see if you can connect to the TM backup with TM. If you can, then you can restore the files and them copy them onto a FAT32 formatted external HD.
    If you network the borrowed Mac with the PC, you can transfer the files over the network, but in any case, you have to use the TM engine to do so.
    The only files on the TM backup that are most likely "normal" would be the original files created during the first backup.

  • Can an external Mac/Time Machine hard drive be connected with Airpot thru USB for wireless backup

    I purchased a seagate 3 tb hard drive and planned on connecting it to my airport via usb. I setup the drive and did the full time machine back up of my imac. I then powered down the airport and the hard drive. I then plugged in the drive and airport and then powered them up. The airport lite up green then went yellow and stopped broadcasting.
    Can these two work together like Time Capsule does?

    I was sort of in the same boat. I ended up getting a 4th generation TC about six months ago. I only got the 2 TB model as I have a number of those WD My Passports laying around. I decided to use the TC's internal HDD as a NAS and use a powered USB hub with two My Passports attached to them for Time Machine backups. I use the 500 GB for my Mac mini backups and the 750 GB for my two other Mac laptops.
    I could have just as easily switched to using the intenal HDD for Time Machine and the My Passports for the NAS. However, I wanted better to use the better transfer rates of the internal drive for my NAS.

  • Safe to delete file from Time Machine hard drive?

    Is it safe to delete a file from an external hard drive that's being used for Time Machine backups? The file is not a backup -- it's a .dmg from the manufacturer of the hard drive. Other than that one file, I don't use the drive for anything other than Time Machine.
    I'm just concerned because I don't want deleting the file to affect Time Machine in any way.
    Thank you.

    I have done it without issue.
