• My USB 2.0 does not detect the USB keys or external hard drives

  I attach my USB mouse and it works fine but I can't detect my external hard drive or memory key USB. Why?

  Try plugging a storage drive (external hard drive or USB key) and go to:
  Control Panel-> administration-> computer management tools
  Under, click on storage disk management
  The storage drive appears in the list at the bottom right? If so, can you do a right click on it and select change drive letter and paths, and assign a drive letter.
  It will now appear in desktop and when you plug it in.

  If the drive does not appear in disk management, can you just tell me if it's a USB port specific, that you are having problems or if readers do not appear in one of your USB slots and also if you tried the discs in another system to make sure that they highlighted it?

• Windows 7 does not detect multiple external hard drives

  I recently bought a HP Pavilion laptop to 7 Home Premium. I have two 500 GB external hard drives. When I connect them individually to the system, they are recognized and I can copy files to and from these External Drives. But when I try to connect both at the same time, Windows 7 does not detect the drive I connect then. Any help is greatly appreciated.

  If the disks are powered by the USB bus and do not have their own external power supply the problem is that the laptop does not provide sufficient USB power to control both.

  The USB specification, is that each port should provide 500mA at 5V. To keep their batteries, laptops usually provide 500mA to share between all available ports. If you need to use several USB devices with significant power, you must either externally powered USB hub or to provide the devices with their own power supply to cutting.

• Windows 7 does not detect my external hard drive

  Window 7 is able to detect my external hard drive under devices and printers, it is able to detect the hard drive, and there is no problem for her.  but only shows no not my external hard drive under my computer icon so I can't drag files

  
  How can I find the hard drive and put the files?
  
  Thank you

  OK follow the instructions;

  • Click the windows icon
  • Right click on computer > then click on scabies
  • on the left, under storage, click Disk Management

  now the hard tip. You must identify which is your external hard drive. It should say something like disc 1 - online (if you have other removable things such as memory card readers may be something like disk5). DO NOT TOUCH DISK 0 (c) because it is your operating system and nothing change may / will kill the system.

  It doesn't have a letter from dirve allocated on the external drive then left and right click then click on change drive letter and paths.

  Assign a new letter perhaps something like L: as who should enter into conflict with what it is then ok the windows... it should now appear.

  Yet once just to reiterate do not assign c: or touch disk 0. you have been warned.

  Here is a link with pretty pictures to help you a bit

  The most difficult part is to find what is your hard drive. Good luck. If you're worried you can take a screenshot of the management of the computer and upload it to your skydrive. We would advise you that it is.

  Hope that helps...

  Hi Deborah,

   

  I imagine the inconvenience that you are experiencing right now. I will help you on that.

  Formatting a disk means configuring the disk with a file system so that Windows can store information in there. Usually, when you install a new hard disk on your computer, it must be formatted with a file system, such as NTFS, Windows can store files that it contains.

• Windows 7 detect my external hard drive, but does not allow me to access it, or see it

  I have a Toshiba 1 TB external hard drive (I threw the box so I don't know what are the specs, but the things written on the back of the room are: ITE HDD E145163 D33033 KCC-REM-DNT-Canv63 N723 Z218 v63600-C 1 TB DC + 5V 1 0 04/12). I remember he said it was compatible on Windows 7, but this doesn't seem to be the case at the moment.

  I plugged my hd; Windows knows it is there and installed the software for it. But I can't save anything in it or access to the workstation. I looked for solutions to this, but nothing has worked. I tried to change the name of the driver [http://windows.microsoft.com/en-US/windows7/Change-add-or-remove-a-drive-letter] by but apparently I can't because my hard drive is a primary partition. How can I use my hard drive with Windows 7 on my HP 2009f computer? : c.

  [Btw, I properly formatted the hard drive on my Macbook Pro]

  Formatting a Mac o/s will be not visible/usable under a win operating system, you would need to delate all partitions, if it is visible and the format in victory

  You cannot change the drive letter of the system drive

• does not detect external hard disk

  Hey guys

  Recently I update my macbook pro (2014) in the sierra of mac os. Since then, my mac does not detect any external hard drive I plug in it even if these drives are detected by the PC and all the files inside. I tried to open utility disk where the hard drive is displayed but the 'volume' located below is gray. When I try to hit mount said volume that nothing happens. All I could do to fix this?

  Thank you in advance.

  Hi sgerolio,

  I understand that you are unable to detect any external drive that you plug into your MacBook Pro, since you upgraded to macOS Sierra.  How many external hard drives work?  How they are formatted?   If formatted for PC, they would not necessarily be able to be read by a Mac.

  You have a small empty external drive or USB key that you can test?  Formatted in Mac OS extended (journaled).  Using the Finder, you are able to see the external drive and drag a file to it?

  The title of the article includes the Aperture application but apply these tips to format an external hard drive to any software application.

  Drives external format Mac OS extended before using with opening

  Take care.

  I have an external hard drive of 4 Marine to... .and a Macbook pro with the latest El Capitan...

  Try using disk utility to repair the disk. If the drive does not appear in the disk utility list, then he dies. Contact the manufacturer or supplier.

  Shut down the computer, disconnect the drive. Wait five minutes and then reboot and reconnect the drive.

  Everything was fine until yesterday. Juice now, when I plugged the external HD into the USB port it does not appear in the 'my computer' window.

Pops up a window saying that "Windows cannot open help and Support because a system service is not ongoing enforcement. " To resolve this problem, start the service named help and Support '. OK, I tried to open 'Help and Support' ' Start Menu ' and the same window appeared again to "not have a system service that runs". I don't know what her soul precisely and I have not the slightest idea of what I need to do to correct this 'disappearance' of Service 'system '.
