Can not read above a drive flash usb 4 GB win 7

My Dell computer does not display the files on the USB STICK beyond 4 GB, I tried 8 GB, 32 GB, 64 GB, none does not appear in Explorer windows, but appear in disk management. I can't reformat it without getting an error. I tried these flash drives/USB drives on an another Win 8.1 and Windows 7 computer are readable. Very frustrated after two days of searching the Web and try numerious suggestions, I had to restore my computer after losing my ability to use Internet Explorer and my external optical mouse after trying some of these suggestions.

    I am running windows vista on the PC of my church and have inserted a USB stick with a MP4 file on it, but I can not read this file. Can I get help?

    I created a video for our Church on a desktop of Windows 7 through Pinnacle Studio 14 (editor) and registered as a .mp4 file. I then put it on a flash drive and put the flash drive in the computer of the Church, that is running Windows Vista, and the file will not play. Please provide help quickly!

  • Computer to read DVD - one message says that I can not read the DVD, except that I have installed a new driver.

    I have a new Toshiba C650 laptop, and he says that I can not read the dvd on it except that I have installed a new driver. Is this true?

    Hi Bill,

    To be honest, this sounds ridiculous but if you get a message, I suppose it could be possible even if I find it incredible.  Do you have it in a (local or online) retail store or Toshiba?  By any chance did you upgrade from the DVD player when buying (where they may have accidentally neglected to update the drivers of the drive that was originally installed)?

    As it is new, Toshiba should help you with this.  Here's the contact page: http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/navShell.jsp?cf=su_contact&pf=true.  Give them everything they need to prove that buy you it and it should be under warranty and then give them the message Word for Word, that you have found.  They should be able to help you.  They can, for some reason I don't know, you don't need to help or guide you through a new driver installation.  I ask for a clear explanation of why this is necessary on a new computer and, if you are not satisfied with the response, ask them to consider that all the faulty computer and replace it.  Even if they won't, he needs the get them less motivated to solve your problem.

    I hope this helps.

    Good luck!

  • Satellite T130 - 10G: Firefox does not read any video or flash content more

    My Firefox does not read any video or flash content more. And in watching the news of repair troubleshooting/malfunction in Firefox under graphics, he said that "Direct2D activated" and 'WebGL Renderer' have been blocked because of the version of the graphics driver.

    I downloaded a new version on the Toshiba site, but an update of the driver can not find the new version.
    I had briefly solved the problem by installing the new driver from the file but it is not recognized in Device Manager.

    Automatic update through Windows just tells me that the driver is up-to-date.
    I have the Satellite T130 - 10G.

    Would be great if someone could help.

    Thank you!

    Hmmmm... as you know Toshiba doesn't support third party software so I think that your question has nothing to do with Toshiba directly.

    Sorry to appear such a luddite acquired but this laptop great USA from eBay.
    User manual appears to indicate that the player is going to adapt to the locality of the drives I want to play.

    See you soon,.

    Hi mate

    I think that the portable player s (optical disc) DVD region is set in the United States and therefore you can not read the DVD released for the European market.

    To resolve this problem, you must change the option of DVD region 2 region.

    My computer-> drive CD / DVD-> properties-> Hardware tab-> choose the CD drive / DVD-> properties-> DVD region

    Notes; You can change this settings ONLY 4 times. After that the parameters is no longer editable.
