My external storage devices do not work.

My laptop is running Windows 8 pro 64-bit version.

Whenever I connect an external hard drive or USB key, it is not detected. I went to the Device Manager, it he showed that there is an error with the usb mass storage device. I checked and it shows the error 38 "code, an instance of the driver is already loaded into memory. Then when I restart my pc, it works fine, but once again the problem returns. I was faced this problem for about a week now.
Is there a solution for this. Please help me out here.

    1. Device Manager cannot start the device.
    2. One of the pilots who needs the unit does not start.

  • Want T15 - J100 Quad Edition Tou: recover the BIOS of the laptop using an external storage device

    So, from the start of my screen is empty and Caps Lock flashes 2 times.  I tried the Windows key + B + power key without success as indicted here:

    http://support.HP.com/us-en/document/c02693833?JumpID=reg_r1002_usen_c-001_title_r0003

    I tried to recover the BIOS with an external storage device but HP's Software and driver download page does not have BIOS updated.  I've updated for Windows 10.

    Where is the BIOS update that is supposed to be here? :

    http://support.HP.com/us-en/drivers/selfservice/HP-envy-15-J100-Quad-Edition-Notebook-PC-series/6521...

    This model seems to have a lot of problems with what I find it everywhere on the internet, but the solutions all return to the download of the update of the BIOS.  I noticed that I can download an update for Windows 8.1.  Are there not one for Windows 10 yet?  Can I use the 8.1?

    The BIOS in the list of drivers of Windows 8 is the last exit for your model. You can use it regardless of the operating system because the BIOS recovery is run outside of Windows.

    BTW-to help the Windows key + B keys. When you press and release the power button / continue to hold the buttons for a few seconds see if BIOS recovery screen appears. I know that it is different from the document - but try it.

  • My DVD player does not work and all the information I can find is "this device does not work correctly.

    Hi, I have Windows Vista and I use a computer laptop Dell studio. When I insert a disc into my CD/DVD drive, the drive spins and it looks like it is about to start and makes the same noise start several times and then just stops. My computer does not record that there is a disc there. If I double click on the DVD drive in 'My computer' it ejects my disc and says "insert the disc in drive E".

    I went on the 'repair' Microsoft online scanner and it told me that there is a problem, but he can fix it. In Device Manager, under CD/DVD-ROM readers I have Optiarc DVD +-RW AD - 7640S. Under device status - general - properties, it says "this device does not work correctly. He also says that I have the updated driver.

    I even uninstalled the driver as a last resort and then restarted my computer. It reinstalled the driver for me, but there was no change. Please help me!

    Hello

    Step 1: Please do all the same underneath if you did some before as is often total
    a process that solves the problem.

    Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
    Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
    RESTART this will refresh the default driver stack. Even if the reader does not appear to continue
    below.

    Then, work your way through these - don't forget the drive might be bad, could be a coward
    cable or slight corrosion on the contacts (usually for a laptop) and other issues.

    Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
    ends. Remove and replace, do not just tight. For laptops, you can often clean power and
    contacts data with a pencil eraser.

    Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
    manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

    ===============================

    Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD
    Burn and CD and DVD read). So it is not unusual for 1 or 2 operational so that other parts
    do it right.

    Did you follow the Troubleshooting Guide for the reader who still does not work? There are some registry
    entries that do not fix the resolution of problems and those who "could" be the cause.

    Check with your Maker system and a device for the two possible firmware updates and the
    correct registry entries for your car.

    Here are the keys in my opinion, are those in question - for the CD/DVD drive of course subkeys as
    There will be other subkeys in these keys. Do not forget to ask involved specific keys as well as the
    Parameters.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\IDE
