Windows 7 does not recognize external hard drive after the reboot

I just bought a WD external hard drive.  I plugged in the USB port and automatically loaded everthing.  I even registered the product.  Then I was told that there was an update to the external hard drive.  I went ahead and put to day and when my computer restarted to him alone is no longer recognizes WD external hard drive.  I had another hard drive that I used where Windows 7 does not recognize it either?  Is it some sort of security setting, I need to adjust on Windows 7 64 bit?  Please notify.

Check if the hard drive is assigned to a drive letter in disk management.

Click Start, right click on computer

Click on management of

Expand disk management

Select your external hard drive if its posted here

Make a right click paths and change drive letter

Restart your computer, open the computer in the start menu and see if it shows then.

  • Vista does not recognize external hard drive (LONG!)

    I bought a Terrabite Cavalry USB Mass Storage 1 unit some time around January 2009. We used it to back up my computers portable wife and daughters without any problems (it was Windows XP a Windows Vista). Shortly after, we have tried to back up my desktop computer, also running Windows Vista, but my computer does not recognize the drive into any USB port. After this attempt, we get is more willing to work on any computer. We contacted the cavalry and they replaced the drive, but we lost a lot of data since most of the files saved on my wife and daughter desktops have been deleted to clean up their hard drives.
    When I received the spare drive I backed up my computer with no problems.
     
    We moved from NC to PA in August of last year and had packed the new car. Recently, we unpacked and used to transfer ALL the photos of my wife, numbering several hundred, again with no problems. In addition, she has saved his computer using the Vista utility. Today, I made the horrible mistake of trying to back up my computer using the same player. I had completely forgotten the previous question. Yet once, my computer did not recognize the drive, any USB port used or on the tabs 'computer '. When the drive is plugged in and turned on, it will be not even allow us to display the elements on the tab 'computer '.
     
    And now, just as before, the player no longer works on my wife's computer either. THIS IS AN ESSENTIAL QUESTION! If we cannot access the drive over 500 photos of our family, covering more than 5 years are lost forever!
     
    Although I've read similar questions on this site (especially in regards to Windows XP) I can't find the one that is exactly the same problem as this.
    There is nothing wrong with my computer. Each USB port works fine. I tried other USB devices with no problems of any kind.
     
    On both computers, if you connect the external drive and the power up it starts with a light blue on the front as it is supposed to. He then became red and Windows makes the normal audio alert, as it does with any USB device plugged. On the bar, the new icon 'Remove hardware safely', says but clicking on that alone causes the computer to get ung place intil the drive is unplugged. The same is tru if we try to access the tab "Computer" in the Start Menu. The computer attempts to load the itms 'Computer' but never the completion of the task. THE TWO COMPUTER DO EXACTLY THE SAME THING! My wife uses a Dell with Vista Home Premium and I use an EMachine with Vista Home Basic. And this issue seems to happen only after using his computer to mine, not the other way around because I had done a backup on thise drive when I got last year and she just did a new now on his own.
    I wrote to the Cavalry, but received no response. They said the last time that they aren't able to recover lost data, and it is said that all over their site.
    The external drive is a cavalry model # CAXP3701PA.
    Someone please help! Pictures of our last five years (including photos of my wife of his precious Golden Retriever from puppy to now) are lost if we cannot solve this problem. It seems that the player works well, but something corrupting of the software driver. We tried again to my wife's computer o and it begins with "Download driver software for device" but then what I described before using it.
    Any suggestions would be greatly appreciated.

    Hello

    Put the disc in a real store of the computer (not the leeks and the glances at a Best Buy or other stores)
    and they can remove the drive from the case and put it in another computer to back up data
    to other media. Of course this cancels any warranty and may not work if the drive has probably
    in fact failed. Data can often be recovered since a failed drive while it's expensive.

    (The drive could be put in either your PC as a 2nd drive).

    I hope this helps.

  • Mac Mini does not recognize external hard drive

    Hello!

    I have a weird question on my Mac Mini. I have two Seagate to 8 external drives connected via USB to my Mac Mini (mid-2011 with Maverics). The discs worked well, but suddenly one of them will not be recognized by the Mac Mini.

    I connected the hard drive of my MacBook Pro and an old PC and it works fine and all files are available, but for some reason, my Mac Mini will have nothing to do with her anymore.

    It does not appear in the finder or disk utility. I unplugged the hard drive for hours and then tried to plug it back without a bit of luck. I restarted the Mac Mini on several occasions. I also tried to connect it to all the USB ports on the Mac Mini. When I connect it to the USB ports, there is no whisper sound indicating that it has started working. However, no sign of it on the Mac Mini.

    It's like the Mac Mini has decided to ignore the external hard drive, no matter what I do. Seeing this works on other devices, I'm fairly certain that the problem lies in the Mac Mini.

    I'm no expert, so any help will be very valuable for me. And if you are kind to help, please explain it to me like I'm 8 or 93 years old.

    Thank you.

  • Windows 7 Starter Edition does not recognize a hard drive WD

    Windows 7 Starter Edition does not recognize a hard drive WD, I used until last month. Device Manager sees it, he sees the USB controller (it lists as a mass storage device), but I can't access the information on the hard disk, or make use of the last backup. I tried to uninstall USB drives - it is not the thing. It gets listed under disk drives.

    Thanks for the reply.

    There was no error message: the device has been recognized (listed) by the USB controller and the Device Manager, but not by the management of the disks - so I couldn't access.

    I managed to fix the problem after:

    -J' scanned the computer (DELL Inspiron) with the Safety Scanner
    -J' completely uninstalled all the software associated with an external hard drive
    -J' uninstalled the USB controllers
    -reboot the system
    -reconnected the external HD
    -After gaining access to the drive, I installed the dedicated software

  • Windows Vista does not recognize external USB 260 GB HARD drive

    I have a 260 GB Seagate external hard drive, a laptop Toshiba satellite and Windows Vista Basic.

    The same Windows usually choose the hard drive when I plug it, it does not appear in Device Manager and in disk management, the only way I can get it to work is to uninstall all the USB root hub and then restart the computer, and then reinstall the USB root hub and plug my hard drive.

    When windows finally recognizes him, the only way to find the driver must choose c:\ manually and there's the search for the computer.
    Works for the time that I have the computer hard disk, but when I stopped it, next time I use the computer, I'm having exactly the same problem.

    I tried to remove the hard drive safely and then close the computer and by him plugging back in after windows has loaded, I tired it connected from the computer and tried to close the computer with connected.

    None of these work.
    Can someone help me please?

    Strange?  :|
    But what need s say Microsoft Windows so I don't expect 100% without bug OS ;)

    Disconnect the USB HDD and remove all the USB ports and Device Manager USB controllers. After restarting again the OS should reinstall ports. Then you could try to reconnect the HARD drive.

  • Seagate Free Agent Desktop does not recognize my hard drive in Windows 8

    My Seagate Free Agent Desktop does not recognize the hard drive on my new computer with Windows 8. Although I can still use it to save and transfer all the data from one to the other, I lose the functions in the menu of the Seagate such as backup and synchronization. It worked fine on my old computer that worked on Windows XP. I tried Troubleshooting compatibility mode and that did not help.

    The message in the Seagate Manager appears as:

    None of the external drives have been found. Make sure that your external drive is connected and turned on.

  • Why my mac does not recognize my hard drive or SD cards?

    I got a new Macbook Air last month. Since I had so much problems with it - mostly because if you plug in anything whatever in the SD card slot or USB drives, it does not recognize them. I own a mac before, as well as PC laptop dell, so I am aware of the problems when formatting the discs everywhere, but even when I plugged a new passport hard drive, the computer couldn't find. Similarly, you may not find all the SD cards when I tried to use the SD card.

    What is going with this? I am a photographer living, so I need constant access to these two. This new model has some new method for transfer of files from the external hard drive etc.?

    Close, then connect the mac to a power adapter, disconnect all external devices.

    reset the SMC

    Reset the management system (SCM) controller on your Mac - Apple Support

    reset all external then pulls even deleted

    Once you open a session reconnect the external hard drive

    If the drive is connected with a hub of party 3rd do not use it and connect the drive directly to the mac

    Connect the external hard drive and open Macintosh HD/Applications/Utilities/Disk Utility disk utility

    The drive appears in the list of external devices?

  • Satellite A300 - Windows 7 does not recognize external devices

    Windows 7 (32-bit) an upgrade of Vista and couldn't be more peripheral to work due to driver problems. Talked to Microsoft and they found that my drivers are still there but can not find them unless I tell them where to look, and so all devices I plug I need to install drivers for both times.

    Any body have ideas how to solve this problem?

    Hi doug47,

    To be honest, I think I can t help you because I know you want to know exactly.

    External devices, you mean? Not everything you need drivers, like external hard drives, USB sticks, etc. These discs will be recognized automatically (plug & play) and they are read to use after connecting.

    If you mean printer or mobile phones you have need of additional drivers. You can get it from the manufacture.
