• External hard drive not detected with the error: "You must format the disk in the J: drive until you can use it."

  Hello

  I have an external hard drive to work perfectly. I'm back from vacation, and it does not appear under "My Computer". It appears under "Devices and printers", however. This is a link to a screencap of Device Manager: http://i.gyazo.com/9e91e1d71ed32c55dba0419e79b499d5.png

  The device in question is that of J:, and it says here that he has 100% free space, that worries me, because he had only 50 GB of free space when I used the latter. After that I open the disk management, I get a pop up message saying: "You must format the disk in the J: drive until you can use it."

  How can I get my hard drive appears again?

  Thank you

• External hard drive not detected

  I have an external hard drive of 4 Marine to... .and a Macbook pro with the latest El Capitan... When I connect the external hard drive for Mac pro, an external hard drive can not detect, but there is a light flashing on the external hard drive. It worked well until last night after I used iTunes and went to another Mac. I still eject properly.

  Any ideas on how to solve this problem

  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.

• External hard drive not detected in Windows 8

  I just bought a Dell XPS 13, running Windows 8.

  I have two external hard drives from LaCie.

  Disc 1 is used with a Lenovo X120e running Windows 7.

  Disc 2 has two partitions, exclusively for my Macbook Pro running 10.9.5 and the other smaller partition is used to move files between Lenovo and the Macbook.

  When I connect Drive 1 to the XPS 13, nothing happens. It is not turn nor it appears in Device Manager.

  If I turn it on to Lenovo, it works very well.

  When I connect Drive 2 to the XPS 13 (to the same USB port and using the same cable), he turns and is detected.

  If the port is working, pilots work, cable works and Drive 1 works when connected to the Lenovo running Windows 7.

  How can I get the XPS 13 to recognize Drive 1? There must be a way to do this without formatting again.

  Thank you.

  The drive is visible in the BIOS or the mode without failure on the XPS 13?

  You can also try to paginate the connection of the power supply in the drive that works.

• External hard DRIVES not detected

  I recently encountered a problem in the recognition of external hard drives of the company. But the usb recognizes pen mouse drivers, card readers etc... can someone help me pls.

  I use HP pavilion G6 2005ax win7 ultimate.

  If it is not giving an error message but it is to let you manually assign a drive letter, then the automount can be disabled (enabled by default).  See the jeffsrawr response in this thread to turn automount.

• Hitachi external hard drive not detected on Windows 7. Disk Management displays "No Media"

  OP: New computer with Windows 7 cannot display files on external hard drive Hitachi

  My Hitachi hard drive is compatible with Windows 7.  This hard drive was working properly with my old computer using Windows XP.  I can see the device in the Device Manager, but I can't view the files.  In disk management, the drive is listed at the bottom of the screen, but said "No Media", however there is almost 50 GB of data stored.

  The hard drive shows in the list of devices and printers when I opened that folder, but does not appear in the list of hard drives on my computer.

  I still don't understand what happened, but I've decided how to fix it.

  After trying my hard drive locked on 4 computers with Windows installed (two with Windows 7) and two with XP and having no success, I decided to plug it into a computer using a Linyx OS (Obuntu).  The computer recognizes my hard drive and open.  Then I was able to use the Windows System.  I managed to freeze hard drive again and he cured the same way.  Maybe this will help also, if you have access to a computer with this operating system.  Maybe a mac would also work.

• HP Elitedesk 800 G2 SFF: external hard drive not detected in the BIOS. Only USB Flash drives are detected.

  Hi all

  I received recently 2 new HP desktop computers.

  HP Elitedesk 800 G2 SFF

  HP Elitedesk 800 G2 TWR

  The goal is to test our real W7 x 64 image on these machines and to inject the missing drivers in the image.

  MDT 2010 to create a deployment on a USB hard disk drive.

  This disc of deployment is already used on 16 different models of HP in the company (Elitebook, zBook, EliteDesk) to install our image so I know it works.

  Unfortunately, the two HP Elitedesk 800 G2, I can't start the boot disk but I cannot to USB for a USB key.

  The USB drive is not detected and not proposed in the BIOS Menu of STARTUP.

  Only the internal HD, external USB Flash Disk, DVD and network devices are detected.

  Here's what I already checked or tried:

  • Latest Version of the BIOS installed (2.05)
  • UEFI Boot has been disabled. (not supported by our record of deployment)
  • USB ports are enabled (front and rear).
  • All types of USB devices are allowed in the BIOS
  • The start command has been changed to start with USB devices.
  • Legacy support is active and Secure Boot disabled
  • Delete the keys to secure boot
  • Reset secure by default startup keys
  • This morning, I created a new disk deployment on a USB Flash drive and it works!

  So, it seems that only Flash USB drives are detected.

  I know it is possible to return the flag removalble on a USB device to cheat the system and make it appear as a disk fixed, but I want a simple solution.

  Does anyone know a fix or a workaround for this problem?

  Thanks in advance!

  For those interested in the answer, here's the final results.

  It turns out that the hard 500 GB external drive can be detected if it is fomatted in FAT32.

  It's strange because my 16 GB USB Flash drive formatted in NTFS works very well.

  In any case, I'll create a FAT32 Partition to the Boot MDT files and put my picture (because the file is too big for FAT32 partition) on the secondary partition (formatted as NTFS).

  Thanks to the technical pre-sales team of HP who helped me with this!

• Second SATA hard drive not detected by Bios and Device Manager

  Original title: second SATA hard drive

  Hard drive not detected by the Bios and the device under Vista Home Premiun Manager

  Hi trinitario,.

  Because the hard drive is not detected in the BIOS also, it may be due to a hard drive configuration that should be changed or a rider. If you need to get in touch with a Local tech-store for assistance.

  Note: change in the BIOS/complementary metal oxide semiconductor (CMOS) settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

• External SSD hard drive not detected by Airport Extreme/Time Capsule

  Hello everyone, I have the following problem:

  Framework

  -J' bought a 1 TB Samsung SSD 840 EVO internal media.

  -He is locked in a case of badges and used as an external hard drive

  -J' have an Airport Extreme (5th generation)

  -J' have a Time Capsule (4th Gen)

  -My MBP detects the SSD external hard drive when it is connected to the USB port and works fine

  Problem

  -I connect the external SSD hard drive to the USB port on both TCapsule and AExtreme, but the HD is not detected directly (USD and with powered hub of USD)

  -HD was formatted as OS x journaled Extended

  -J' tried smb and cifs via 'connect to server', but does not work.

  Any help will be greatly appreciated.

  Juan

  Unfortuantely, Apple did not update the firmware on the USB key (it is still 2.0) port on their routers for a number of years.  As a result, new USB 3.0 drives may or may not work with airports.

  Yes, we know that USB 3.0 is supposed to be backward compatible with USB 2.0 in theory, but theory does not always work in practice.

  If your drive is formatted as Mac OS extended (journaled)... also called HFS +... .and you have tried the drive with and without a USB hub powered and the reader will not be displayed with you check using the AirPort Utility disks tab... then you have one of a number of readers who do not work with routers from the airport.

  I just checked a new LaCie USB 3.0 drive I have here. It works perfectly with a Mac, but it appears not at all when I connect it to the USB port or a powered new AirPort Extreme or new Time Capsule directly, or by using a USB hub.
