External Hard Drives: One for backup and one for storage

Is it possible to have two external hard drives, one firewire and the other usb, using one as an additional hard drive, and the other as the backup drive, and backup from the external that is the additional hard drive to the the other which is the external back up drive?

Wunjo:
Welcome to Apple Discussions.
It is possible, but not necessary. If you have a large enough firewire HDD you can partition it so that one partition is approximately the size (capacity) of your internal HDD. Then you can make a bootable clone of your internal HDD to this partition using a utility like SuperDuper or Carbon Copy Cloner. You can then regularly update this partition so that you always have an up-to-date backup of your internal HDD. This will serve as a backup of your internal HDD, as well as an emergency boot drive. You can also boot the computer from it to run diagnostic tests and repairs on the internal HDD.
The rest of your HDD can be used for whatever you wish. You can create additional partitions for different purposes, or just leave one large partition as a storage or work area. If you need directions for partitioning your HDD, do post back and ask.
Of course, if you already have a firewire and a USB drive, you can use them as indicated. In any case, you can partition the drives to serve multiple purposes.
Please do post back with further questions or comments.
Cheers

    Trying to copy ANY file from my MacBook Pro to an external hard drive spins for 45 minutes then fails. I hate this computer and WISH I never would have wasted my money. Any ideas? WD My Passport 2TB Drive, had to buy a program to make the POS read files. Copies that would take seconds from a Windows based machine never complete. I have to close the transfer or shut off the machine half the time. Worst computer I have EVER owned, crashes non-stop, constantly freezes, and seems like EVERY operation is more complicated with this thing. Literally, my 1997 Compaq was FAR MORE reliable and user friendly.

    This is one of the messages I keep getting; The Finder can’t complete the operation because some data in -- File Whatever -- can’t be read or written.(Error code -36)
    I have copied things to the hard drive in the past, but it has always been incredibly slow, and now just seems to freeze and fail

    You need to convert the VOB files in the TS-Folder of the DVD back to DV which iMovie is designed to handle. For that you need mpegStreamclip:
    http://www.squared5.com/svideo/mpeg-streamclip-mac.html
    which is free, but you must also have the  Apple mpeg2 plugin :
    http://store.apple.com/us/product/D2187Z/A/quicktime-mpeg-2-playback-component-f or-mac-os-x
    (unless you are running Lion in which case see below))
    which is a mere $20.
    Another possibility is to use DVDxDV:
    http://www.dvdxdv.com/NewFolderLookSite/Products/DVDxDV.overview.htm
    which costs $25.
    For the benefit of others who may read this thread:
    Obviously the foregoing only applies to DVDs you have made yourself, or other home-made DVDs that have been given to you. It will NOT work on copy-protected commercial DVDs, which in any case would be illegal.
    And from the TOU of these forums:
    Keep within the Law
    No material may be submitted that is intended to promote or commit an illegal act.
    Do not submit software or descriptions of processes that break or otherwise ‘work around’ digital rights management software or hardware. This includes conversations about ‘ripping’ DVDs or working around FairPlay software used on the iTunes Store.
    If you are running Lion or later:
    From the MPEG Streamclip homepage
    The installer of the MPEG-2 Playback Component may refuse to install the component in Lion. Apple states the component is unnecessary in Lion onwards, however MPEG Streamclip still needs it. See this:
    http://support.apple.com/kb/HT3381
    To install the component in Lion, please download MPEG Streamclip 1.9.3b7 beta above; inside the disk image you will find the Utility MPEG2 Component Lion: use it to install the MPEG-2 Playback Component in Lion. The original installer's disk image (QuickTimeMPEG2.dmg) is required.
    The current versions of MPEG Streamclip cannot take advantage of the built-in MPEG-2 functionality of Lion. For MPEG-2 files you still need to install the QuickTime MPEG-2 Playback Component, which is not preinstalled in Lion. (The same applies to Mountain Lion even though that has it preinstalled.) You don't have to install QuickTime 7.

  • External hard drive time machine backups not mounting

    I have used Seagate 500.11 external hard drive as a backup location for the time machine for over two years. I just got a message that it had not updated in over thirty days.  It is not listed on FInder, but it is listed on the disc utility.  The Time machine backups  are grayed out on the disc utility screen and cannot be mounted, even after the repair and verification tests said that their volumes were ok.  What should I do?

    Time Machine does not create bootable clones. It does not even create a bootable backup. If that's what you prefer then do not use Time Machine.
    If you use Time Machine then you must allocate at least twice as much space for the backups than the capacity of the drive you are backing up. A 2 TB backup drive would be suitable for a 1 TB main drive or smaller.
    If you plan to create a bootable backup, then partition the backup drive with one partition the size required for the clone. Then use the other partition for you additional storage neeeds.

  • External Hard Drive problems with iTunes and iPod

    I recently purchased a 320 gig external hard drive for my computer, hoping in part to load my iTunes library onto it. Obviously I'd have much more room on disc than my actual iPod, so I was going to manually manage my music (an option I didn't have selected on my iPod before).
    I followed all the online help topics which have all been helpful so far. I organized my music files, changed my directory, consolidated my library, and now everything is on the external hard drive and is working just fine.
    The problem comes when I connect my iPod. iTunes barely even seems to recognize my iPod all of a sudden, saying that it has been corrupted and needs to be restored. When I try restoring it, nothing happens, and I can't seem to do a thing about it through iTunes. Of course, there's actually nothing wrong with the iPod at all, since it still works fine and plays music exactly the same as before. It simply won't update or do anything at all when hooked up to my computer.
    I know this has something to do with the new hard drive, since everything was just fine a few hours ago, I just can't figure out why I can't get my iPod to sync all of a sudden. Like I said, my iPod is working fine otherwise, iTunes is playing music through the external hard drive without any issues, and I haven't touched any files other than music files (I haven't even deleted them off my original hard drive yet, so all the original fines remain unchanged, even though I switched the directory).
    To the best of my knowledge, all my software is up to date, and the iPod is a 30 gig photo. Any ideas?

    Yeah, I gave the new drive the letter Z, so there shouldn't have been any conflicts there. I also tried your other suggestion, and while the computer recognized my external hard drive, it didn't seem to make any difference once I plugged in the iPod again.
    I've been wrestling with this for days now. I've tried changing the drive letters for both the external hard drive and my iPod several times (but no matter what, the iPod always seems to take F when it's unplugged and then plugged back in). I've tried restoring the iPod on multiple occasions. I've tried reinstalling all my USB drivers. I've consolidated my music library on several occasions (I now have two identical libraries on my external hard drive), yet annoyingly, iTunes seems to keep switching file paths away from the external hard drive and back to their original locations on the C drive. I'm trying to free up internal hard drive space, not house 30 gigs of media on it. That's what this new external hard drive is for.
    Somehow, I was able to get them both to be recognized at the same time, but it never lasts long. I'll start iTunes with the external hard drive disconnected, plug in my iPod, wait for the iPod screen to come up in iTunes, then plug my external hard drive back in. Then, I can miraculously start to transfer music back onto my iPod, but iTunes doesn't seem to want this to happen for some reason, and will usually cut off the transfer. So far I've managed to put three whole songs on my iPod.
    So now I'm trying to do two things. One, the same as before, get my computer and iTunes to recognize both my iPod and my external hard dive at the same time. And two, get iTunes to stop changing the file paths back to the C drive. These files are already on my external hard drive and don't need to change.
    (As a side note, I should comment on how helpful people are on this discussion board. The Apple representitives I called on several occasions seemed totally unwilling to help, acting more like pushy salesmen than anything, while people here seem to be much more friendly and knowledgeable. Just thought it needed to be said.)

  • Is there an external hard drive available for Lion?

    Is there an external hard drive available for Mac  OS X v10.7?

    How big of a drive do you want? Western Digital USB MyPassport drives work great and are inexpensive. You can buy them Mac formatted or just buy one that isn't and use Disk Utilities to format it for a Mac. As far as I know any of the external drives will work with OS X Lion.
    I use a 500GB MyPassport. My MacBook Pro mid-2010 has a 320GB drive and i'm using less than 60GB so the 500GB external is plenty for my back up needs. I use it with Time Machine and SuperDuper! (for bootable images) in Lion.

  • External hard drive setup for time machine reading as a virtual cd

    Why is my MacBook Pro reading my external hard drive setup for time machine reading as a virtual cd?
    Thanks

    Hi Christian,
    Is this something that has happened from the start? If so, I would reformat the disk and setup TM from scratch again.
    Prepare the external HD by connecting to the Mac, open Disk Utility, select the manufacturer’s name of the external HD, select Partition and choose GUID Partition Table, format to Apple OS Extended (Journaled); quit Disk Utility.
    Open System Preferences.
    Click on Time Machine.
    Click on “Select Disk.”
    Click just to the left of "On" to turn TM on if it's not already on.
    Click on the disk or partition you want to use.
    Click on “Use for backup.”
    Leave external HD connected, and TM will automatically do its thing.

    My external hard drive will not open and only shows up in Disk Utilities. When I try yo repair it, it give me and error of invalid sibling link. How do I fix my external hard drive?

    Invalid sibling link may not be fixable by Disk Utility. (Disk Utility is very conservative, and will not attempt repairs that might cause you to lose data.)
    It is an indication of serious Directory damage.
    that leaves
    a) third-party Utilities that will take those risks, or
    b) re-initializing the drive (which deletes all your data) and restoring from another backup source.
    c) "Copying off whatever files you can salvage" has gone by, and you cannot copy anything off a drive that will not mount. You may be able to use "rescue" programs such as prosoft engineering Data Rescue to copy files to another drive, but that sounds a lot better than its reality. You may get many files, but not get ANY filenames.

  • External hard drive - reformat for my Mac book - HP

    I gues I need to reformat it please can you explain to me how I do this.
    Thanks

    Welcome to Apple Support Communities
    Your external disk is formatted with NTFS, a filesystem that OS X doesn't support in order to copy data to this filesystem.
    If you don't want to erase your hard disk, you can use an application like Paragon NTFS that will allow you to write in your external drive without having to format your external disk.
    Another option is to format your external disk. As you have movies, you should format it in exFAT. You have to format the external drive on a PC unless you haven't got a PC. If you want to do it on a Mac, use Disk Utility > http://pondini.org/OSX/DU1.html
    If you aren't going to use your external drive with PCs, you can also use "Mac OS Extended (Journaled)", designed for Mac OS X but it won't be read in any PCs

    Sorry we are unclear as to the external hard drive and its connection to the TC..
    For instance the light that blinks.. is that the TC or external hard disk or what.
    Did you try just rebooting / restart the whole network in correct order.. modem.. router / TC.. external drive.. clients with 2min gap between each.
    Are you actually running Snow Leopard as the profile states?
    How old is the TC?
