Disk utility says Everything is Fine, when it's not

I am trying to understand what the point of disk utility. I checked (several times) my boot drive (SSD) and a second internal HARD disk, disk utility says it all goes well and nothing in need of repair. Meanwhile, I can say drives are certainly * not * ok since I get poor system performance, and the HARD disk is sprayed randomly when I access/copy some files.

I went and got the SMART utility and Disk Warrior, SMART utility written my boot drive is FAILING and my HARD drive has FAILED.

I am now under DW on it, but I'm pretty annoyed that utility disk is essentially useless to see if there are problems with the discs...

Disk utility and disk warrior can only repair the files in the directory, they are unable to repair a disk that is physically / mechanically failing.

  • Why Firefox type and slider are slow to a normal start, but everything works fine when I reboot in safe mode?

    When I open FIrefox normally, the movement of the cursor is very jerky - seems stuck on each link. In addition to typing in any box is delayed. When I restart with disabled modules and in safe mode, the cursor moves very well and typing is normal. I disabled all my Add - ons, but that doesn't seem to help as whenever I restart, the cursor jerky and delayed typing again. What's wrong?

    Try disabling hardware acceleration in Firefox.

    In the Firefox Safe mode, these changes are effective:

    • all extensions are disabled
    • the default theme is used (no persona)
    • userChrome.css and userContent.css are ignored
    • the layout of the default toolbar is used

  • iTunes says: I'm updating when I'm not

    I recently updated my Windows 8.1 for Windows 10 and I am running iTunes vs 12.1.2.27. I have the settings to automatically search for updates, and it used to do that on Windows 8.1. Now on W10, when I manually select "Search for updates", the message box comes up saying I'm already under the latest version, but I see we vs 12.4.0 out there today.  Why is this?  I'm on a laptop Dell Inspiron, W10 64-bit.  Any suggestions? Thought I would ask before downloading a new facility and what might cause other problems.

    Hello demenzes

    Thank you for reaching out to the Apple of community support. I know it's important to keep things up-to-date so that your software is always running better there. In such cases, particularly with the upgrade to a new operating system, it may be a good idea to do a clean installation of iTunes on your computer.

    This will take some time, but this does not alter your data in music or media in your library. When you re-install iTunes everything will be right there ready to go.

    This article will guide you through removing iTunes and its related programs, 5 in total, and then you can re - install iTunes on apple's site:

    Remove and reinstall iTunes and the components of the software for Windows 7 and later versions

    If you are having problems, the community is there to help.

  • Windows Vista Security says McAfee is installed when it is not (I think)

    I have windows defender because I was sick of the Security Center shouting that my pc is not protected and I was sick of hiding updates all the time. I also installed Norton. I uninstalled McAfee off my pc when I installed Norton. Now the windows Defender said that my virus programs are incompatible and that McAfee is still there. I went through Add/Remove, I looked in program files manually and I even went through the registry - deleted a single stray McAffe register, but he always says that he is there. I'm a little frustrated now. If there is someone who knows what I do, I would be very grateful. Thank you!

    Hello

    Run the McAfee removal tool to remove the remains. Good time to uninstall Norton and run its
    Both removal tool. Use something less bloated and more compatible such as recommended
    below.

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

    Here's what I use and recommend: (these are all free and very effective versions.)

    Avast and Prevx proved extremely reliable and compatible with all I have
    launched on them. Microsoft Security Essentials and Prevx have also proven to be very
    reliable and compatible. Use MSE or Avast and Prevx, Prevx 3 but not all.

    Avast Home free - stop any shields is not necessary except leaving Standard, Web, and
    Operation of the network.

    Prevx - Home - free

    Windows Firewall

    Windows Defender (is not necessary if you use MSE)

    Protected IE - mode

    IE 8 - SmartScreen filter WE (IE 7 phishing filter)

    I also IE always start with asset if filter InPrivate IE 8.
    (It may temporarily turn off with the little icon to the left of the + bottom
    right of IE)

    Two versions of Avast are available 5.x and 4.8 x

    Avast - home - free - 5.x stop shields you do not use (except files, Web, network, &)
    Shields of behavior) - double click on the icon in the Notification area - real time Orange - click on the
    Shield that you want to stop - STOP. To stop the Orange icon to show an error indicator-
    Click on the Orange icon - top right - settings - click on the status bar - uncheck shields you
    disabled - click OK
    http://www.avast.com/free-antivirus-download

    Avast 4.8 x - home - free - stop shields, you don't need except leaving Standard, Web,.
    and the network running. (Double-click the blue icon - look OK. - upper left - Shields details
    Finish those you don't use).
    http://www.avast.com/free-antivirus-download#TAB4

    Or use Microsoft Security Essentials - free
    http://www.Microsoft.com/Security_Essentials/

    Prevx works well alongside MSE or Avast

    Prevx - home - free small, fast, exceptional protection CLOUD, working with other security
    programs. It is a single scanner, VERY EFFICIENT, if it finds something come back here
    or use Google to see how to remove.
    http://www.prevx.com/   <-->
    http://info.prevx.com/downloadcsi.asp  <-->

    PCmag - Prevx - Editor's choice
    http://www.PCMag.com/Article2/0, 2817,2346862,00.asp

    Also get Malwarebytes - free - use as scanner only. If you ever think malware and that
    would be unusual with Avast and occasional Prevx running with the exception of a low level cookie
    (not much), to UPDATE and then run it as a scanner. I have a lot of scanners and they
    never find anything of note that I started to use this configuration.

  • Say there is jams when there is not.

    The printer stops, says there is a jam and there isn't.  I looked and there is no bits of paper stuck inside.  He wil make loud slamming noises or grinding noises and then stop and say he is blocked.  I just press OK and it usually comes out.  Sometimes, he will spit on a white sheet or it will not print the sheet that "stuck".  And now it's printing the pages a little twisted.  I checked the cartridges and they move freely, the paper is stacked evenly and 20 pounds of paper.  Don't know where to go from here.  Thanks to all those who may have an idea!

    Given that the 4500 is seen frequent paper jam messages, and the impressions come out twisted, I bet the problem is dirty rollers. Follow the steps described in this document. Most of it you probably did, but in any case, follow the steps just to double check. If this does not work, try the resets listed below. If none of this works, you need to replace the printer.

    To do a hard reset:
    1. make sure that the printer is turned on.
    2. pull on the power cord from the printer.
    3. pull out the power cord from the wall.
    4. wait for 30 seconds.
    5. plug in the printer and turn it on.

    To make a partial reset:
    1. make sure that the printer is turned on.
    2. pull on the power cord from the printer.
    3. pull out the power cord from the wall.
    4. wait for 30 seconds.
    5. plug the power cord into the wall, but do not connect the printer.
    6. press 3 and # buttons.
    7. while now buttons, plug in the printer.
    8. when the lights come on, release the buttons.

    Earlier, I bought a computer and just noticed that a sticker on top said he had a touch screen, but it doesn't do anything when I touch it... I'm just stupid?

    No, you're not stupid!  If you provide the model of the computer, I'll see if I can figure out whether or not he has touchscreen.  It wouldn't be impossible to believe that an incorrect thumbnail could be placed on a computer.  Many of the same components are used in different models.

    I'm guessing that you have had an internet connection and your PC downloaded a update that his having difficulties to install.  Try to leave this connection and the update manually.

    Hello

    I saw this kinds of problems occur with the power strips and even UPS systems. And some similar questions have
    been solved using them actually, especially the UPS. If the power strip has important circuit protection
    He'll probably bad or you have very low power at first on this AC circuit.

    Solution is not to use the tape and maybe get a UPS with brown-out solution.

  • Cannot install Flash Player as it says that I have when I'm not?

    Hi all

    On Web sites with videos I can't watch them as it says you do not have Flash player and I need to download adobe flash player. The main one I use is Twitch.tv. I click on this link to download it, but having said that I already have flash player and try the troubleshooting for Windows 10 method. This does not at all. Whenever I try to download it, it goes to this troubleshooting instead of the download page page and says he works. But it is quite obviously not. I'm under 10 64-bit windows.

    I hope you can help.

    First of all, check that the ActiveX filtering is configured to allow Flash content:

    https://forums.Adobe.com/thread/867968

    Internet Explorer 11 (and Edge) introduced a number of changes both in the way the browser is identified with remote web servers, and how it treats JavaScript for behavior targets specific to Internet Explorer. Unfortunately, this means that content on some sites will be broken until the provider of content changes their site to conform to the new approach to development required by the modern versions of IE.

    You can try to work around these problems by using the compatibility view:

    http://Windows.Microsoft.com/en-us/Internet-Explorer/use-compatibility-view#IE=ie-11

    If it's too inconvenient, using Google Chrome may be a better alternative.

    If you have a discreet set of links that work in some browsers but not IE/Edge, links would be useful to determine if this is a content problem, flash problem or a matter of IE/Edge...
