  • Win 7 Backup and Restore does not recognize the USB flash drives.

    Win 7 Backup and Restore does not recognize the USB flash drives for a backup image or a recovery disc.  Given that Windows 7 Starter Edition is used in many, if not most of the netbooks and netbooks have no optical drive, support for flash (thumb) drives would be very handy, especially for repair and recovery.

    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
    the entries in registry that the troubleshooter does not solve and those who "might" 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 that I of course are those in question - for the subkeys of the CD/DVD drive
    as there will be other subkeys in these keys. Do not forget to ask specific keys involved as well as
    the parameters.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\IDE

  • IS does not recognize the drive HARD internal

    I have three, all from a school lab, that have been linked with other positive points and printers.

    They are connected are not together anymore.

    All three have a floppy drive and a HARD drive. Will only boot from the HARD drive.

    At startup, the other two do not recognize their HARD drive and I use ea disk with the system in this regard.

    Since hard drives are not 'seen' I am unable to do anything with them: fix, set up as a boot drive, etc.

    They begin with the usual chimes and the Mac with the question mark, I slip the disk in and they complete commissioning.

    The internal drive spin up and the indicator light flashes.

    They do not show the drive HARD internal on the screen, but will show an external.

    I haven't started to swap parts between the good and the other two.

    Does anyone have an idea on how to activate an invisible HARD drive?

    You will need to use the boot floppy disks to start the machines to run the repair disk, partition and format the HARD drive if it is still functional. Only then can you install Mac OS on the HARD drive. That's all that I remember.

  • Satellite Pro A10 does not recognize the drive WEIRD AD - 7540A model

    Hi all.

    I just bought a new model slimline DVD rewritable AD - 7540A, brand Sony NEC Optiarc. When it is plugged into the computer laptop and for the POST, it appears the 'IDE #1 error' message after the operating system starts, I am unable to open the drawer and no CD/DVD can be read.

    I checked this drive on another laptop from another brand, and it works fine, so the problem is not in the drive itself. Could someone help me?

    Thanks in advance.

    The problem is simple.
    Your phone does support not all readers of CD/DVD slimline because different or bad master/slave/c-salt settings.

    The IDE #1 error message indicates that the BIOS cannot recognize the device connected to the #1 IDE controller.

    In your case, the solution is simple; you need to buy a compatible CD/DVD player and supported

    Mayen a user manual would provide details on the management of records.
    If not, then contact the ASP in your country and ask some compatible devices!

  • Y410P does not recognize the drive HARD and "Bad sector found" errors

    Hello, having problems with my son's laptop. He has recently updated to Win10 and after a day, the computer would not boot and did not recognize the existence of an operating system. I was able to create a bootable USB 8.1 and the operating system is now operational. However, there is no reconition of the HARD drive only SDS. The BIOS shows as available but who runs the Lenovo's Diagnostics tool (results below) translates into bad sector errors. Is there a way to recognize/recover the drive or do I need to replace? Thanks in advance. Cheers, Dave

    Thank you for the interpretation. Is there something specific that allows me to know that the ST1000LM024 of HARD drive is defective? I guess that I'lll need something to get a claim under warranty. Thanks again.

    The last part of your post (smart test) says that it is defective. To confirm this further you can try to physically remove the hard drive and connect it to another computer as an external drive or a secondary drive for further tests using the manufacturer's diagnostic program. BTW, Seagate is the manufacturer of the disk hard so that you can go to their site and download their program.

  • Philips +/-RW DVD8631 will not recognize the drive

    Hello
    My computer specs are:
    Dell Dimension 8300. Multiprocessor PC ACPI. Intel Pentium 4 CPU 3.20 GHz 2 x Radeon X 300 series. ATA Storage Controller - 266F, Intel 82801FR SATA AHCI Controller, Intel 82801FB/FBM.

    My problem is that I filled my disk space and would like to burn files to CD - R or DVD-R for free space. I select the files I want to burn and ' move to ' the drive can burn data (Philips +/-RW DVD 8631). When I click on "Write these files to CD" it opens the Assistant when you type the name of the disk. I type the name and click "next". Then, I get a message that tells me that there is no disc in the drive. I used the software 'Identifier of DVD' which was recommended on the forums before, and it does not recognize the disc in the drive. I use DVD + R 8 x produced by "imation".

    If there is someone who can help, I'd be very happy. Thanks in advance to those that do.

    Thank you

  • Windows does not recognize the USB flash drive

    Hello
    My USB does not work when I plug. It seems that Windows recognizes the device because it is found in the Solution Explorer window, but if I want to create a folder or a file on the USB key I have the following message:
    "Cannot find this article.
    It is no longer in < %3="" null :="" optext=""> . Check the location of the components and try again. " < br=""> also the files that are copied to the USB flash drive are not visible in Explorer and it looks like the drive is empty.

    I want to emphasize that the same (Kingston) USB flash drive works perfectly under Windows XP operating system on another computer so it may not be a problem with the device. The same problem also appears when you use a different USB (another manufacturer).

    Thank you!

    Hey, 101 a.

    , I just posted a fix I found for my USB flash/go to work again.  It was a very simple solution, too.

    I unplugged all USB devices first, then tried my USB jump drive again.  IT WORKED! I've narrowed the problem to the new printer that I use.  It's a Mono Dell Laser MFP 1125.  Whenever it is plugged into a USB port, my USB doesn't work.  All other devices work, but not the USB is the printer is connected

    I don't know what done to block the flash/USB key, but unplug printer allows the jump command to work again.  I will contact Dell on what did the printer driver to block the flash player.  Just an info on the fix I found.
