Why won't my MBPr read my external ssd drive?

hello.  quick question for anyone who may have some suggestions.  i've been using aoyen digital u32 shadow ssd drive for a few months now with my 2007 macbook pro.  i got this error message the first time i plugged it into my new macbook pro retina.  i've heard that people are having issues with the usb ports (in particularly the right one).  though this message is popping up with both of my ports when i plug in my drive.

  • Why won't my MacBook recognise my external hard drive?

    I've just upgraded to a new MacBook.
    I have a Maxtor Mini4 external hard drive which I used with my old iBook G4 (running OSX 10.4).
    When I connect the hard drive to my MacBook it isn't recognised (it doesn't appear in Finder and the MacBook doesn't acknowledge the existence of the hard drive in any way).
    I've downloaded the Maxtor software and installed it successfully on the MacBook.
    Any ideas on why the MacBook doesn't recognise the hard drive? (the hard drive is powered by USB - it has no external power cord).
    I still have my iBook and it continues to recognise the hard drive, so there is no problem with the drive.
    Thanks

    Are there two USB plugs connected to the wire coming out of the drive? Do you see the drive in your System Profiler? Even if it doesn't mount, it should show up in there.
    I second that suggestion as the first thing your should look at. I had a SimpleTech drive that worked off of one port on a certain PC, but didn't mount with a single plug on any of my Macs. It always showed up in the USB Tree in System Profiler although I'm guessing it gave up trying to mount after sampling the power output.
    The USB ports are likely to be and sometimes there are enough differences in the power output of two USB ports that a bus-powered hard drive can work in one but not the other. In general it's because a bus-powered device doesn't properly work with a standard spec 2.5W USB port.

  • Why won't my iMac recognise my external hard drive?

    I have a new 2012 iMac 27" and it won't recongnise my external hard drive. It's a Seagate GoFlex desk adapter USB 3.0 and will not come up in Finder or Disk Utility. I'm new to Macs andk unsure what to do.

    Are you correctly using one of the new required "USB 3 Compatible" cables for the connection?  A "USB 2" Rated cable will not work.

  • Why cannot my macbook air read my external hard drive?

    First of all, I have an external hard drive (Western Digital - WD5000H1U-00). I went to their website, downloaded the WD driver installer, and then installed the drivers. I even had restarted my MBA but when i plug the usb cable of my external hard drive, MBA can't read it. Why is that so? In my other computers, the external hard drive could be read.

    It's probably formatted for Windows. Plug the hard drive into your MacBook Air. Open Disk Utility (User Name>Applications>Utilities). Go to the Partition tab. Select 1 under Volume Scheme and also click on options and choose GUID. Click Apply. That's it. But if you have any files on that drive, back it up because this option is going to erase your drive.

  • Why won't my Extreme recognize an external Hard Drive?

    Just bought a new Apple Airport Extreme (my first Apple product and not happy) and connected an external Hard drive to it via USB but I can't get my PC to recognize it.  I can see it when I log into the extreme under utilities but that is it.  I tried 3 different hard drives, 2 are in FAT32 and the larger one is NTFS.  I followed Apple's instructions under disk sharing and still nothing. 
      I would greatly appreciate any advice to get this working.

    Good evening.
    Only drives that are formatted in FAT32 or Mac OS Extended (Journaled) will be compatible with the USB port on the AirPort Extreme.  NTFS and exFAT are not supported.
    Unfortunately, we have few Windows users here, and I am not one of them, but one of the Apple Support documents below provides 3 methods for PCs to connect to a drive at the AirPort Extreme. The other provides general information about format compatibility.
    Hopefully, one of the PC guys will post soon to provide additional information.

    I believe that you have 90 days of free phone support with a new Apple product, so you might want to explore that route as well.

  • Why won't my mac recognize an external hard drive?

    I purchased an external hard drive to back up my mac. When I plug it into the USB ports, the computer does not recognize it. I've tried all of the USB ports on the computer. I know the drive is okay because my laptop does recognize it.

    How do you know it's not recognized and how is it formatted?

  • Why won't my computer recognize my external hard drive anymore?

    I have an external hard drive I was using all morning. This afternoon, the hard drive isn't showing up on my desktop. It does show up in my system profiler under usb. When I go to disk utility to repair it, it isn't there. Please help!!!

    No. Any other external drive I plug in works. This particular one, I was using the morning before it disappeared. I know the drive works with this computer I have been using it with this computer for months with no problems. It shows up in the system profiler (image 1), but not in disk utility (image 2) or on my desktop (image 3)

  • Why my new iMac won't read my external hard drive?

    Why my new imac won't read my external hard drive??

    Liz,
    Sorry for not responding sooner, I support your position completely - as for the external drive I assumed that the individual was a previous mac user and knew about that (my mistake) at home I have a couple of external drives
    one drive is acknowledged regardless of format (mac/win) its a partitioned drive.... the other one - far as the mac is concerned does exist when i connect it.  I believe its a win only drive (will have to check the specs on it) but it works on the win-notebooks.
    so my point of reference was coming that perspective, with no additional posts I have to assume you had the correct answer.  have a great day.

  • Why can't iTunes play music from read-only external hard drive?

    I have a write-protected external hard-drive which I keep all of my iTunes media on. iTunes recognizes all of the files, including the metadata on the id3 tags, and can find the files in Windows Explorer. However, it cannot play the files while the drive remains write-protected. Is there a work around for this as I would prefer to keep the hard-drive protected? Why does iTunes require write-access to play songs? Other media players have no problem playing from my read-only external hard-drive. Thanks for any help

    Welcome to the Apple Community.
    When you say you can't play through both devices at the same time, what happens when you try, are you able to select multiple speakers, do they deselect themselves, do you not get the option or does it just not work when you select multiple speakers.

  • Why did lion stopped reading my external hard drives?

    I have a MBP which used to work fine with snow leopard, had also Paragon's NTFS software to allow reading my external hard drives (Western Digital's My Passport and Passport Essential with about 2.5 TB worth of data, music, photos, etc.) I decided to upgrade to Lion and after that... poof! my hard drives will show grayed on the disk utility with the "not mounted" message and my MBP will not read the data, even though it can access them, run the WD utility, unlock the drive but... nothing.
    Any ideas on how to fix? I event spent the morning yesterda wit the Geniuses at the Apple store and they were clueless too. I did show them on a couple of snow leopard machines my data but they could not understand how to explain he issue. I loaded the WD's drivers for Mac (OS  X Lion support as advertised on their website) but nothing happens.
    Fortunately I can still read my data on any other computer (my kids MB's, my office Windows, etc) but it is truly dissapointing that Lion has brought down all the good stuff Mac / Apple had been known about.
    Any takers to this one?

    Has the connection changed e.g. a different usb port?
    You may need to allocate a permanent drive letter to the external hard drive.

  • Powerbook G4 won't detect USB 2.0 external hard drive

    I recently purchased a Toshiba USB 2.0 portable external hard drive. I have both 15' and a 17' Powerbook G4s that are running on OS X 10.4.11. When I attempted to connect the new hardware to each of the computers neither recognizes that anything has been connected. The external drive does not appear on the desktop, in disk utilities, or TechTool. Both computers have 2.0 USB ports and the external hard drive is compatible to a Mac, but I cannot figure out why it will not show up. I have tried all of the suggestions I could find in forums discussing similar problems such as trying to repair the permissions with the Disk Utility First Aid feature, resetting the PRAM, as well as resetting the PMU, but to no avail. When I connect the device to a Windows based PC it shows up immediately; however, when I try to see it using the Virtual PC side of my Mac I am still unable to visualize the drive. This problem is only occurring with external hard drives and not particularly just this brand--I have tried others and had the same problem. All of my other USB devices that I connect to these computers work fine. Can someone please help and tell me why my Powerbooks will not detect USB external hard drives. Thanks!

    External hard drive enclosures can be connected to computers in any of several ways. USB is one; FireWire is another. Some enclosures offer several different connection options: they may have any combination of USB2, FireWire 400, FireWire 800 and eSATA ports. All G4 And G5 Macs have FireWire 400 ports, and can start up from an external hard drive that is connected to one of those ports. No G$ or G% Mac can be depended upon to start up from any external drive that is connected to a USB port, though it may happen in a few cases. Because a FireWire-capable drive is bootable, it's much more useful than a USB-only drive in any situation where a primary hard drive has failed or has become temporarily unbootable because of file or directory corruption.
    Bare hard drives nowadays come in two platter sizes: 2.5" for notebook computers and 3.5" for desktop computers. The sizes and shapes of their outside casings are tightly standardized to make them highly interchangeable. They also come in two types: Parallel ATA, also called IDE, PATA, or ATA-5, ATA-6 or ATA-7; and the newer Serial ATA, or SATA drives.
    External enclosures are made to accept either PATA or SATA drives — rarely both types. If you have an external drive with only a USB2 port, and you can see how to open the drive enclosure to reveal the bare drive inside, it may be to your advantage to order an empty FireWire enclosure and "transplant" your bare hard drive into it to get the benefits of higher speed, bootability, and adequate power that come with FireWire.
    External hard drive enclosures are designed to hold standard-sized bare hard drive units — the same units that can be mounted inside a desktop or notebook computer. An enclosure contains a place to mount the drive, a circuit board or two that mediates between the drive and the port to which you'll connect a USB or FireWire cable, and in the case of a 3.5" drive, sometimes a fan for cooling.
    Portable FireWire-connectable external hard drives seldom or never have the problem of insufficient power that plagues so many portable USB hard drives when they're used with Powerbooks. For whatever reason, Powerbooks' USB ports just can't put out enough juice to run most portable USB drives, while their FireWire ports are able to do so comfortably.

  • Cant read usp external storage drives on windows

    anyone know why I can't read usp external hard drives used as mass storage devices on windows?? They contain mac files but no big deal....just jpg files mostly. I thought you should be able to read them similar to memory sticks, memory chips, etc...

    Hi and welcome to Discussions,
    in addition to Axels post, you can have a look at MacDrive http://mediafour.com/products/macdrive/ which so far is the only way to enable Windows to read and write Mac formatted harddisks.

  • How do I get Photoshop Elememnts 7.0 to read my external hard drive?

    I have a signature 500 gp hard drive that pse 7.0 will not find or read.  In order for me back up photos I must do it through Digital Photo Professional or trhough Windows.  No matter what I try i cannot seem to get pse to read the external hard drive.  Can anyone shed some light on this subject?

    Just to be sure...I'm reading your post as your external is not available in the navigation list.
    I'm assuming the USB (or firewire) is connected to your computer. I have a couple and have on occasion turned one on and had the USB plugged in for the one that was off.
    This next link probably isn't going to help as it's how to navigate to an external...but I'll include it anyway.

    Not sure what else it can be assuming the external is good and doesn't have any compatibility issues with your OS or Elements.  Hopefully, someone else will pipe up if they have any ideas.

  • HT5149 Final Cut Pro x won't recognise any of my external hard drives

    Hi, I am sorry to start a new thread on this topic as I am aware there are already numerous threads. I have been searching through them for a solution to my problem and nothing appears to be working.
    As stated in the title, Final cut X won't recognise any of my external hard drives. When I open Final cut x all I see is an "Untitled" event in the library and not even a mention of my internal drive.
    I have checked that all my hard drives are formatted to Mac OS Extended (Journaled) which I can confirm they all are. I have a spare hard drive which currently has no content on it and I have just reformatted it using disk utility to Mac OS Extended (Journaled). This hard drive is not showing up in the library either. I mention this as some of the suggested solutions appear to be that an external hard drive not showing up might be because of folders within the hard drive labeled something such as "Video" "Audio" or "DCIM,"  as this may cause Final cut x to see it as a camera device and not a hard drive. This hard drive has absolutely nothing on it and has been reformatted just 10 minutes ago, yet it still does not show up in my final cut x library. The weird thing is... all the hard drives show up in Motion 5.
    I am really stuck and I don't know what to do. I am currently in the process of re-installing final cut x to see if that will change anything. I will post what happens as soon as it has been reinstalled. I can provide screenshots as soon as it has been reinstalled. 
    Does anyone have a solution to this? Has anyone had the same problem and found out what I must be doing wrong? I would greatly appreciate any comments or feedback which might provide some insight into what I am doing wrong. I feel like this must be an error on my part as I am not that adept at using final cut x.
    Thanks,
    Chris

    I am using the latest version. Currently re-installing final cut x which will bring me up to date.
    Thank you for taking the time to reply. That makes a lot of sense.
    However I still can't understand something... I only have 100gb free on my internal drive and I want to optimize a large amount of footage for my video projects. How do I save my projects to this hard drive if it is not showing up in my library?
    I appreciate I am probably being very stupid and am very grateful of any insight!
    Thanks,
    Chris

  • I just upgraded my operating system on my MacBook Air and now my laptop won't detect my Toshiba 1T external hard drive

    I just upgraded my operating system on my MacBook Air and now my laptop won't detect my Toshiba 1T external hard drive, how to solve this problem?

    Try some of the troubleshooting steps outlined below:
    Troubleshooting an external hard drive
    > Unplug the hard drive, wait a few seconds, and then plug it back in
    > Restart the computer
    > Unplug any other peripherals from the computer
    > Plug it into a different USB port
    If none of those steps work, see if it is recognized in Disk Utility.
    Checking a disk with Disk Utility
    To check a disk using Disk Utility, launch the Disk Utility application in any of the following ways:
    > Type the first few letters of its name into Spotlight. Select it from the results.
    > Go Launchpad > Utilities > Disk Utility
    > Go Applications > Utilities > Disk Utility
    Once Disk Utility is opened, check to see if your external HD appears on the sidebar. If it doesn't appear at first, try the troubleshooting steps above again while leaving Disk Utility open, each time checking to see if the external HD appears.
