Changine from a FireWire connection to a USB connection

I have been using my iMac and its FireWire ports to connect an additional hard drive and my backup drive to the iMac. I backup my files using TimeMachine. I plan on getting a new MacBook in a month or two. I use two OWC drives that have both FireWire and USB ports. I plan to backup my MacBook to the same drives as I backup my iMac. There is plenty of space. My question is this:
Can I simply replace unhook the FireWire connection and use a USB2 connection on the drive when I backup my MacBook? I would assume that the connection used won't change how the data is stored on the drive, but... One never knows when hi-tech is involved.

Yes. It makes no difference which port you use. The drive will still be used as it normally would.

  • Yosemite won't Boot from External SSD with Firewire Connection

    Seeking help, I boot from external SSD drives from my 2010 iMac. I recently installed Yosemite on an External SSD with a firewire connection and all went well with the installation and first boot. After completing set up and restarting my iMac Yosemite will no longer boot from the firewire connection it will boot to the loading bar and then get the dreaded Goest Buster Emblem, if I swap out the SSD to USB connection it boots normally. I have 6 SSD Drives with Mavericks and Lion installed on that will boot from the Firewire Connection.  Any suggestions ?

    Additionally when testing while the SSD is connected to a USB Connection and booted if I attach any firewire device they are not recognized or connected to the operating system.

  • Migratiing files from a MacBook Pro to a new iMac via firewire connection

    The firewire connection does not appear to work between my older MacBook Pro running 10.4.11 and my new iMac running 10.5.6. I've been trying to use migration assistant and it never gets passed "waiting for old mac to restart". I 've put the target macbook pro into target disk mode by pressing "t" at startup and then using system preferences, start up disk, start disk in target mode. It appears that the iMac just can't see the older mac. Any suggestions to trouble shoot? Very little info on apple's support documentation. I have over 90 GB of data (music, files, photos). I can do this over a network connection but it will take 30 hours just to copy my itunes library.

    I would start by doing the following on the MBP:
    Repairing the Hard Drive and Permissions
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Next, turn off both computers. Connect via a Firewire cable. Boot the MBP into TDM. Wait for the TDM screen to appear. Now boot the iMac normally. See if the disk drive of the MBP doesn't appear on the iMac's Desktop.

  • Switching between the firewire connection and USB 2.0 Connection

    Is it possible to switch between the firewire connection and USB 2.0 Connection on a portable external hard drive? I've tried unsuccessfully to use the firewire connection on my external hard drive after using the 2.0 connection. No machine will read the drive if it is connected via the firewire port. Using USB 2.0 it works as intended.

    Hello Grizzly Marmot,
    Thank you for the feedback. So probably my old MAXTOR enclosure is playing me tricks ....
    Last night the backup on my USB 2.0 was terribly slow ??? The incremental duplication of my hard drive (372.9 MB of data from 35GB of complete data) gave me these stats:
    Copied : 6232 files, 372,9 Mo
    Average : 8,8 Mo/minute (4,5 copying, 148,1 verifiying)
    Just to analyse the drive it takes ±45 minutes ??? Also could the energy saving mode be a slow down factor (the suspension of the computer is NEVER) ???
    I still wonder what speed I could experience for a wireless backup to a NAS drive ??
    Thanks for helping.

  • Can i import the video from a camrecorder with only a USB connection?

    Hi, I am very new and may i ask some silly questions? I was using an very old DV camcorder with a firewire connection and it worked fine with my Mac, but now I want to buy a new camcorder and i found that the models I like do not have the firewire links, only they have the USB, the models with the firewire links are very old styles.... can anyone tell me what to do with only the USB link? thanks!

    Panasonic HD camcorder, HDC-SD1
    Advanced High Definition (AVCHD) isn't supported by Apple you will encounter editing limitations wait for the apple software to catch up with this format.
    Panasonic SDR-H250
    Panasonic's hard disk model, 3CCD, MPEG2
    the only thing this cam has going for it is the 3CCD, converting the already compressed mpeg2 video to the DV format for iMovie will result in an additional lost in quality an will be time comsuming (not to mention the extra app(s) neede for the conversion.
    ) you'll need for the conversion .
    Here's what I'd do. I'd purchase a solid mini DV cam with all the bells and whistles and wait for the dusk to clear on the all new/problematic formats. In the process saving $400 - $500.
    Don't become all hyped up with the marketing crap for these new cams. Sony Vegas 7 is the only app I know of that just recently updated to handle the AVCHD format. And until comsumers start burning HD DVDs whats the point. A good mini DV cam will still be viable a couple of years down the road and todays new cams will be cheaper and better.
    Here's a sweet cam that will allow you to take videos and edit them in no time.
    Sony DCR-HC96,
    Analog-to-Digital Converter, external Microphone Input
    Analog Audio/Video Input(s) just to mention a few of the most sought after features.
    You can find this cam on the web (eg. amazon.com) for about $500.
    Then again that's just what I'd do, other my have different advice/suggestions.
    Hope this info is of some use.

  • Firewire connection is not supported. Use USB to transfer songs...

    Got message on my ipod saying "Firewire connection is not supported. Use USB to transfer songs" and then it says "Press Center to dismiss"
    Restarted the ipod no use!
    Connected with my PC no use! (its just charging) does not update of hooked to itunes)
    Any ideas how i can fix this??
    P.S I have tried cleaning the docking and the cable for any dirt still no use!

    Does it give you this error all the time or only when plugged in with the cable?
    If it does it all the time, have you checked the dock connector for bent pins?
    If it only does it when plugged in, have you tried a different cable?

  • How to add USB 2.0 or FireWire connections?

    Hi everyone,
    I already have a USB 2.0 hub attached to my MacPro because all the available slots are taken but I would prefer if the periferals were directly plugged into the Mac. Is there any other way to add extra USB 2.0 connections or better yet, FireWire connections to the MacPro?
    Rio.

    Hi Rio,
    I had a problem when I installed the PCI Express cards. The cards worked fine but there was a problem with automatically putting the system to sleep. If you have your system set to sleep automatically after a certain amount of time and install the cards then the system won't go to sleep automatically. I had this problem with an older G4 and my new MP. Apple told me that was normal and they expected it to be fixed in Leopard. I ended up returning the cards.
    I'm not the expert, but that was my experience.
    Good luck.

  • I can't transfer my files from my Power Mac G5 to my Mac Pro using firewire connections. Has anyone else had this issue?

    I can't transfer my files from my Power Mac G5 to my Mac Pro using firewire connections. Has anyone else had this issue?

    Don't choose from another Computer, because with the older one in Target mode it really isn't a Computer, just a big Firewire Drive, choose From another Disk...

  • I just used a firewire connection to transfer files from an older MAC to a newer MAC. My newer MAC has lost all that was on it, and all the applications are opening like they have never been used before and asking for Rosetta. Help!!!

    I just used a firewire connection to transfer files from a PowerBook G4 to a MacBook Pro. The MacBook Pro has lost all that was on it, and all the applications are opening like they have never been used before and asking for Rosetta. How do I find all my files on the MacBook Pro, or undo what I have done???

    IGNORE the last post: he thought you are using Lion or Mountain Lion.
    Since you are using Snow Leopard, you need to install Rosetta.  It can be found on your Snow Leopard Install DVD in the Options section.
    Once installed all should be well again.
    Also, if your computer is connected to the internet when the Dialog Box about PowerPC applications comes up, it MIGHT allow you to download Rosetta from the internet.  There has been some discussion that Apple has discontined internet download of Rosetta into Snow Leopard.
    Someone else will have to address your lost files problem.

  • When I connect the USB dongle from the camera connection kit I get an accessory not supported by iPad message. The card reader triggered the same msg but works now. Same msg with vga. Have tried rebooting

    When I connect the USB dongle from the camera connection kit I get an accessory not supported by iPad message. The card reader triggered the same msg but works now. Same msg with vga. Others have posted this problem but the only suggestion anyone has offered is to reboot, which doesn't help. I've tried.

    Thanks Fred. The nearest Apple store is about two hours away, so we did the next best thing & took it to Best Buy. It stumped the "Apple Guy" there. Apparently when an Apple product is turned on it works. Period. I'm impressed that the products are normally so dependable--it just stinks that I got the one in a million that's not. Anyway, now we wait for a service call Tuesday morning. Thanks again!

  • TS1253 Can I print from my iPad 3 to a USB printer connected to my time capsule?

    Can I print from my iPad 3 using a USB printer attached to my time capsule via the network. Thanks!

    You might want to take a look at an app called Printopia to see if it will do what you want. There is a free trial, so you will know if it will work before you buy.

  • Error message: "FireWire connections are not supported.  To transfer songs"

    I recently purchased a Monster iCarPlay to play my ipod in my car. I have had no problems until recently. Upon disconnecting my ipod from the iCarPlay wire, I the following message popped up: "FireWire connections are not supported. To transfer songs, connect the USB cable provided." It also prompts me to click the center button to dismiss the message. However, I'vd followed these instructions, and the message does not go away. Does anyone know what I can do to resolve this problem? Or is it anything to worry about?

    That is the message you see when you attach a 5th gen iPod to a computer using FIREWIRE. so... i suspect that for some reason, the 3rd party iCarPlay device must be confusing the iPod into thinking it is being docked or attached to a data line of some type and not simply charging.
    As for the sudden occurrence of the message, it does seem strange however, keep in mind that you are using a 3rd party device that may not be supported or endorsed by Apple at all.

  • Can I download a DV tape to Premier Elements without a firewire connection?

    I recently purchased a new HD camcorder as well as Premier Elements 10.  One of the tasks that I'd like to accomplish via Premier Elements is to download my old DV tapes to my hard drive, which the software seems to support.  The instruction manuals and video tuitorials mention that this transfer / capture must generally be done with a firewire connection (which my computer does not have).  However, my new HD camcorder downloads via a USB connection without a problem.  I tried to download from the DV camcorder using a USB connection and (sure enough) Premier Elements wouldn't recognize the old camcorder.  Does anyone know why is this a problem / what the compatibility issue is?  Is there a way to download the DV tapes to my hard drive without having to purchase and install a new firewire connection to my existing computer and buying a new firewire cord?
    Thanks in advance for any help offered.

    For Capture of tape in PrE, you will need FW. If your computer does not have FW, then you have a couple of choices:
    Add a FW (IEEE-1394) card
    Add a FW connection to a laptop via either a PCMCIA, or ExpressCard
    Good luck,

  • I have deleted my private folder and do not have enough space to reinstall my operating system. How can i transfer files from my hard drive to an USB drive to free up space when the operating system isn't working. or do i need to erase disk?

    i have deleted my private folder and do not have enough space to reinstall my operating system. How can i transfer files from my hard drive to an USB drive to free up space when the operating system isn't working. or do i need to erase disk through disk utilities without erasing data (but will it delete my programs such as photoshop, office, creative suite?

    Connect the computer to another Mac and put it in FireWire Target Disk mode, or use the Disk Utility to clone the drive or image specific folders with the USB drive as the target. After you've copied off everything you want, you'll likely need to erase the drive and reinstall the applications.
