Can one external drive be connected to two USB devices?

I am wondering if I can connect an external HDD to the AE USB port so its on the nextwork and also connect it via firewire or USB to an HD 1080 Media player (connect to TV). Or is this going to cause problems if I do this at the same time?
Thanks for any help!

Or is this going to cause problems if I do this at the same time?
Yes. A hard drive shouldn't be connected to two or more controllers at the same time unless it's specifically designed for that, which few drives are. A controller is a computer, AirPort Base Station, that media player, or anything else which attempts to access the drive directly.

  • Can one Cisco IPS 4360 connect to two different ISP circuits?

    Hi,
    Currently our network has two circuits from two different ISPs, with two firewalls in the middle of the ISPs and the corporation internal network. We are thinking of purchasing a Cisco IPS 4360 and put the device between the ISPs and the two firewalls.
    We would like the traffic coming to/from ASA1 still use the circuit from ISP1, and ASA2 still use the circuit from ISP2. Is this possible? Can the 4360 route the traffic as we want?
    I drew a draft picture of this issue. Please have a look at the attachment.
    Thank you!
    Regards,

  • HT201250 Can I use Time Machine on two different Macs to back up to one external drive?

    Can I use Time Machine on two different Macs to back up to one external drive?
    I have one 1T Western Digital backup drive that works well with Time Machine and my MacBook Pro.  I now want to back up my wife's MacBook Air using Time Machine on her Mac and want to know if I can use the same WD external drive or if I need to get a 2nd back up drive?  If I can use one external drive for the two Macs do I need to do something special on the drive or will Time Machine do it automatically?

    Yes. You will need to configure Time Machine preferences on each computer to backup to the same drive. Note that you cannot connect the backup drive to both machines at the same time.

  • Can I transfer data from one external drive to another using my MacAir as a platform?

    I am trying to transfer about 94 Gigs of data from one external drive (Touro) to another (Seagate) using my Mac Air which only has about 14 Gigs of available space.  How best can I accomplish this operation?

    Niel - I know that I must be a real dunce on this.  I tried opening the additional window on finder and then dragging and dropping from the Touro drive to the other open finder window for the Seagate drive.  Again, it bounced back.  What is NTFS? And how do I find if either or both of the drives are formatted in that manner?
    Again, thanks for you help on this.
    JC
    PS  I just got the info on the Seagate that it is Windows NTFS formatted.  What do I do now?  Is Paragon something I can download off the Internet?  Why, since I formatted the Seagate to run on my Mac Air would there still be a problem?  The packaging on the Seagate says it is compatible with Mac OS systems. jc

  • I've copied my itunes library onto an external hard drive.  Is there any way I can do this and delete songs from my PC without also deleting from the external drive? Already lost two songs!!!

    I've copied my itunes library onto an external hard drive.  Is there any way I can do this and delete songs from my PC without also deleting from the external drive? Already lost two songs!!!  I just want a back up - using a work PC and don't want others accessing my songs.  Hope someone can help.  Thanks!

    I see. To get a better idea of what is being stored where please download and run the script iTunesInfo which should output something like this:
    I'm interested in the block of 4 results starting ITL location. If your profile name shows up somewhere replace it with <Name>.  It is also worth checking under Edit > Preferences > Advanced to see where iTunes thinks your media is supposed to go. My script estimates the setting based on the location of the first media file it can actually find.

  • HT2518 how do i or can i drag and drop files from one external drive to another ???HOW

    how do i drag and drop files from one external drive to another, i cannt get both drives to open up. only one at a time.. i have alot to learn i know but that is where i am at the time...

    You posted here so would assume you are also talking about running Windows.
    Are the drives NTFS and use on Windows?
    Are they Mac HFS formatted?
    You likely will need NTFS for OS X in one case. to mount PC and use under Mac OS Lion
    MacDrive to mount and WRITE to HFS drives under Windows

  • How to transfer from one external drive to another?

    I am trying to move files from one external drive to another.  I can write to both drive from my Mac.  When I do a large transfer using Finder, I only get a few files and an error code 50.
    I'm using two Seagate drives, one formatted for Mac only and where I'm writing to, and one formatted for PC and Mac.  I have written and read successfully to both drives.

    I moved some movies and some seldom listened music (coped the files) into a folder on the Lacie drive. Then I reimported them to the main itunes library while holding down "option". This created a link to those files to the external. the files show up in my itunes but cannot be played unless i have the Lacie connected to them.
    See this link.

  • How can an external drive cause my Internet to slow to a crawl and then fail?

    I have two WD My Passport Ultra 1 TB USB 3 new drives. One I'm using for Time Machine and one for CCC (Carbon Copy Cloner). I have been trying to use them with my new MacBook Pro retina 13-inch.
    For the last few days I've had weird problems trying to connect them via a USB 3 hub. I though the hub was the problem (because things seemed to be fine until I introduced a hub into the equation) and already returned one.
    But now I see the same thing happening even without the hub.
    It appears that one drive, when connected to a USB 3 port (it doesn't matter which port), even when it's doing nothing (I erased and and removed the CCC task), causes the Internet to slow to a crawl, and then stop. All connectivity ceases.
    The instant I unmount and remove the drive the Internet springs back to normal speeds - over wifi about 110 Mbps.
    Disk Utility says there are no problems with the disk. So does WD's only diagnostic utility. And the firmware is up-to-date.
    The other disk, running Time Machine, seems to have no issues at all.
    I guess I will return this drive. It could be subtly defective in some way. But what way? Why would an external USB 3 drive affect the Internet connectivity?
    doug

    I came across this post while in search of the answer to the very same question only I am experiencing this problem when connecting to a USB 3.0 hub and nothing else.  The resuling slowdown in my internet speed leaves me hanging intermittently between screens in Safari, sometimes indefinitely.  When I remove the USB cable, normal speeds resume.  Activity Monitor shows no undue load on the CPU.  I did not notice this problem until just recently.  Could this have something to do with the recent OSX patch.
    BTW: I am running a 2012 15" MacBook Pro with Retina display. 
    Anybody have a clue as to what might be going on here?

  • How do I move an iTunes library from one external drive to another?

    I need to move my iTunes library from one external disk to another, because the original disk is about to fail. So, I went into iTunes Perferences --> Advanced, and set the library to a new, empty folder on the new drive.
    Nothing changed. I expected all my music to vanish from iTunes, so that I would have to re-import it. However, all the music remained, still on the old disk. At this point, if I were to recreate the library on the new disk, I would have all of my music twice.
    Is it possible to move an iTunes library from one external drive to another, or am I stuck with my original choice until I buy a new machine? If I can move it, can one of you clever folks explain how it could be done?

    Paul Seymour1 wrote:
    However, those are all dealing with old versions of iTunes that still contained the Advanced --> Consolidate Library command which is no longer part of the app. (I'm on iTunes 10.6.1.)
    Consolidate is still part of iTunes.
    It is in iTunes menu File > Library > Manage library > Consolidate.
    The article you linked to is old and it is (and was) a hacky way of doing it.
    Just copy the entire /Music/iTunes/ folder to new location, hold Option (Mac) or Shift (Windows) when launching iTunes.

  • How do I save 2 iphoto libraries onto one external drive?

    Hi
    I have an iphoto library on my MacBook Pro and I have an older library of different photos on my graphite iBook.
    I'd like to store all my photos onto one external drive.
    How can I do this without losing either library in the process?
    I actually have the same question regarding music on iTunes.
    Thanks
    AS

    Make sure the drive is formatted Mac OS Extended (Journaled)
    Do you want to merge these libraries into one? If so, then you'll need the paid version ($20) of  iPhoto Library Manager
    It's the only way to merge Libraries while preserving all metadata, versions and so on.
    Otherwise, simply rename one of the Libraries (so they don't overwite each other) and Copy the iPhoto Library from the Pictures Folder to the External Disk. in each case.
    To choose which library to open: holf down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location.

  • Copying video files from one external drive to another

    Hello! I am very new to Apple and FCP, so please forgive my ignorance. I have looked through the other topics and have not found one that addresses my question, so please forgive me if this has been addressed in the past.
    I am working on a project and have all of my video clips saved to a G-Tech G-Raid 320 GB extenal hard drive. I captured much of my footage using "capture now" instead of logging individual clips for various reasons (i.e.: some tape sources did not have timecode), so if I ever have a problem, simply recapturing the footage does not appear to me to be a valid option.
    With this weighing heavily on my mind, I thought it would be best to copy the poject to a second G-RAID external hard drive.
    However, the G-RAID uses an 800 firewire and my G5 computer only has one such port.
    What would be the best way to copy from the one external drive to the other? Will I have to copy the files to my internal hard drive first? And if so, how do I do that? Thanks!!

    Crystal,
    Please reply to a specific post, not to your orignial one. This keeps the threaded discussion in order.
    To see the format for a drive. Open Disk Utility. It is located in your /Applications/Utilities folder.
    You should see all your connected drives on the left side of the window. Click on the icon of the drive you want information on. Select the Volume icon, not the Drive icon ( the volume icon is the one under and slightly indented to the right of the drive icon)
    Look at the bottom of the window. You'll see an item FORMAT: it should say Mac OS Extended. If it says MS-DOS, you'll need to ERASE the disk. When you do that, you'll have the option of changing the format.
    Do not right click and COPY. Simply drag the icon of the folder containing your media files from one disk to the other. It will copy by default.
    good luck.

  • Lightroom - how to restore backed up files (not Lightroom catalogue) from one external drive to another?

    How to restore backed up files (not lightroom catalogue) from one external drive to another.
    I recently backuped my photo files from one external drive to another. The backup (carbon copy cloner) pointed to some corrupt files on the original drive.
    I have deleted those files and am finding good copies of them  in Time Machine backups.
    I want to get rid of the original external drive; use the recent backup as my main external and then back it up onto a brand new drive.
    What I am not sure about is how to point lightroom to the backups so it knows to look on the new drive instead of the old drive and all those exclamation marks and question marks go away.
    There are close to 60,000 images in numerous folders all with one 'parent folder.'
    My best guess is from Lightroom Help - Create and Manage Folders -  Locate Missing Folders
    Can I point to the one parent folder and all the subfolders will come back?
    Is this the process to recover files into lightroom and will there be a problem with so many photos?

  • Moving LR files from one external drive to another

    How do I move LR image files from one external drive to another external drive?

    Move the photos using your operating system and then re-connect in Lightroom following these instructions: Adobe Lightroom - Find moved or missing files and folders
    Do not use this as an opportunity to re-arrange folders or move photos from folder to folder. Just move the entire "tree" of folders.

  • How to move Startup Disk clone from one external drive to another?

    I thought this would be a question easily answered on the WWW and easily found via search engines, but so far no luck, hence this question.
    Prior to upgrading from Lion to Mountain Lion I followed some very good instructions from Tom Nelson on ask.com (http://macs.about.com/od/backupsarchives/ss/diskbackup.htm) related to using Disk Utility to clone my internal Macintosh HD drive to an external hard drive, making it a bootable drive.  I cloned to a very nice LaCie external FW drive that had far more room than that needed for the clone.  This drive booted just fine as a startup disk, so mission accomplished:   I have now a bootable clone of my Lion system prior to upgrading to Mountain Lion. 
    The upgrade to Mountain Lion went well, and now, before I put any additional apps or much additional data on the original internal  Macintosh HD drive, I want to use Disk Utility again to clone the drive so I'll have a snapshot of the system right after the upgrade to Mountain Lion.
    Questions: 
    Is there any way to use the same LaCie drive that now holds the Lion startup disk clone to hold the yet-to-be-done Mountain Lion startup disk clone?  
    If not, how can I move the Lion startup disk clone from the oversized LaCie external drive to a drive more the size of the Lion clone (approx 140G)?   The LaCie drive is far too roomy and nice to have sitting gathering dust for only 140G to be used in an emergency restore. 
    Thanks in advance for your advice.

    Good info Csound1, and thanks. 
    So my final question (I think):  How does one move/copy a startup disk clone from one external drive to another, and still have it bootable on the new external drive?   I'm still considering freeing this LaCie drive up for more dynamic storage and getting another drive for the bootable startup disk clones IF I can move this Lion startup disk clone to a new external drive. 
    I guess the summary question is:   how does one clone a startup disk clone?  As I think about this, and recall the Disk Utility screens, couldn't I simply select the Lion clone on the LaCie FW external drive and do the same operation I did with the original internal Lion drive?  Basically the same steps as before but this time the source is the LaCie FW external and the destination is a new external drive? 
    Thanks again; wonderful forum here with very smart people.
