After you install a second WD 1 TB my book drive, Windows Explorer does not see the new drive.

Original title: Signature Collision?

I'm having hard to the installation of a second external drive. I use Windows 7 Ultimate RC. There was a WD 1 TB drive My Book already installed - healthy and works very well. The problem occurred after installing a second WD 1 TB my book reader. I followed all the instructions, pluuging the drive to a USB hub. Windows found the disk, installed drivers and reported the new drive ready for use.

Windows Explorer does not see the new drive. Devices and printers shows 2 external drives from WD. Disk Management shows as 2 drives, but the second disk is offline because of a 'Signature' Collision

Each player works very well if it's the only drive plugged in. "Eject My Book" does not work because a program (or more) are to use the player in the background (Windows or Norton).

I installed the latest firmware and I'm still having this problem. I've been emailing WD with this problem and they are running out of ideas.

Can anyone help?
Thank you

Hello Comatose13,

There is an old article of KB in Windows XP that has been recently updated with additional measures to solve this kind of problem. The KB covers Windows XP, Windows Vista and Windows 7 with step by step methods. See if that helps.

    If its SATA you need SATA drivers to install. Since the XP CD doesn't have the SATA drivers on it

    Unless you disable the AHCI in the BIOS. Or their wake.

    Or get the SATA drivers. Check out them on diskette, press F6 during installation and then add them.

    Hello

    I try to install XP SP3 on HP Pavilion dv9000, but XP Setup does not see the hard drive.

    Can you please point me in right direction - what I do files and how to add them to the XP SP3 installation CD necessary?

    I guess that somewhere there is a step-by-step detailed guide.

    Thank you

    Enter the BIOS by pressing F10 at startup. If you have the option of Bios Setup to disable the native sata mode, XP will install without problem, no sata driver needed. It will be on the tab of the System Configuration.


    If you do not have the setting in the Bios, it's the driver sata for your machine:

    Device drivers for a Win 7 install on Ubuntu system

  • Install Windows 8 does not recognize the system drive

    I built a new machine (chart below). Since this is a new machine and not an upgrade, I bought Win 8 Pro 64 bit OEM to do a clean install. The SSD is my system disk that Windows 8 will be installed. Four data drives are mirrored, two for the other two. Construction went perfectly. The BIOS recognizes all six disks: 1 SSD, 4 HDD, 1 DVD.

    Insert and boot the disk of Windows 8. Accept the EULA, enter the product key. Arriving at the page "Where do you want to install Windows?", only four hard disks are listed. The SSD (installation to go) is not found by Win 8. ??? I tried to change ports SATA, cables, power supply - no difference. For each new change of hardware, the BIOS still sees everything. This isn't a hardware problem.

    The question remains: why the installation of Windows 8 does not recognize the SSD drive. All five disks are on AHCI. I'm not in RAID.

    I spoke with crucial technical support of all (manufacturer of the SSD). They were also surprised that the drive does not appear in the list.

    Does anyone have a solution? I spent all the money on hardware, as well as the new version of Windows and I cannot install it.

    This is the real kick in the teeth: Microsoft won't support me. The OEM of Windows 8 version is the same as manufacturers, such as Dell or HP. Support told me I had the support of the manufacturer. HA! I am the manufacturer. Either that or upgrade from an earlier version of Windows. This means that any that a new construction machine will get ZERO assumption of Microsoft. All just great.

    Thank you in advance for any assistance.

    Windows 8 Pro 64-bit (full version) - OEM

    Rosewill Challenger-U3 ATX Mid Tower Case
    SeaSonic M12II 620W 620 Bronze PSU
    ASUS DVD writer

    The DSS must be LOW LEVEL FORMATE.

    Once, there may be no other [HDDs] not connected to the SATA ports.

    Install Windows 8 Pro now.

    [Edit] Can someone please mark this as answered? I can't because I posted the question. Thank you.

    I select the 'Home Oracle Middleware' directory:

    On the next screen does not appear that there is a weblogic Server installed on the machine, but it exists and works on:

    / Home/Oracle/Oracle/middleware/Oracle_Home/wlserver

    foto3.png

    What can be?

    According to the matrix certification > it seems http://www.oracle.com/technetwork/middleware/bi/bi-11gr1certmatrix-ps6-1928219.xls , OBIEE 11.1.1.7 is not certified with Weblogic 12 c... Take a look at the roadmap "Web and application server interfonctionnements" of the matrix.

    If you want to install the software only, then I think you should use a version of certified weblogic as 10.3.6 and repeat prior steps. The installation wizard should be able to detect your installation of weblogic 10.3.6.

    Kind regards

    I installed the new version of LIghtroom (2015) compared to the creative clouds.  Creative cloud said that I installed the new version.  However, the shortcut icon that has been installed does not start the new version.  I also went on the link properties itself, but without success in starting.  How to launch the new version?

    Thank you, toinimj59.  I did this part and the installation is complete (there is apparently not earlier--included an acceptance of the general terms and conditions...)

  • Install HP does not see the printer in network, Windows DOES. Help!

    Hello

    I am trying to add my HP Officejet k8600dn to Windows 7 (32 bit) so I can scan, but the HP Installer (add device) can not see the printer. The unit is set up by cable to a switch on my network via an ethernet cable. If I go into the menu "Add a printer" Windows, I can install the printer very well. But I have to be able to scan and I don't know what to do.

    Tips on getting functional analysis if the HP software is unable to see my printer? Subnet mask and gateway on the printer are the same for the computer and the printer. I typed the correct IP address in the "Add a device" menu of HP, but he sees not just it. ARRGG!

    Thanks for any help!

    Hello

    I think that there is some confusion because the Officejet k8600dn is only a printer, it is not a multifunction device and does not provide the capability of scanning.

    You can find the specifications below:

    http://support.HP.com/us-en/document/c01287217

    If you have any different model printer, please specify the exact model.

    Kind regards

  • View composer does not see the VM images parent after Virtual Hardware 7 upgraded?

    I upgraded to 4.0.1 view last month, then there are 2 weeks, we have upgraded to vSphere. After the upgrade, I upgraded to VMware tools of a VM parent, improved virtual hardware 7 and took a new snapshot. When I go to the view admin console I don't see the new snapshot, I made available in the form of default image. It works very well so that the virtual machine is stored virtual hardware version 4, but breaks after moving to 7.

    Did I miss a step? Anyone else seen this problem? I'm close to the opening of a case of pension on the issue.

    It is an option on an existing pool.  Just change the pool and go to either host or a cluster.  The box should be at the bottom of the page.
