How to disable the file hiding (changing options for hard disk does not work)

Hi all

I hope someone can help me with the following problem:

-J' need to open a file of 16 GB of content in third party software (Stata) who reads completely in memory.

-Due to Windows caching file, necessary to get the procedure done about 32 GB cache files and Stata access physical memory.

-As I have only 24 GB of physical RAM file is read later part of virtual memory, which leads to serious performance problems.

I unchecked the box 'Enable write on the device cache' to my hard drive. That did not help. Is there a way to disable the Cache during PLAYBACK of files?

Thank you very much in advance for any help!

The write cache and virtual memory are different. Virtual memory is an extension of the physical memory residing on the HARD disk where Windows is installed. Normally, the virtual memory is about twice the size of the current physical memory. Write cache is an exclusive setting for external hard drives only and has no effect in internal hard drives.

In your case, please note that full 24GO of RAM will not be allocated to the program. At least 1 GB will be reserved for windows, so the rest of the programs are moved to virtual memory, which means that the HARD drive. It is not recommended to disable virtual memory because it can cause stability problems. In addition, the files are not copied directly in memory, even if they are big. Instead, the parts of the file are available and this area, including the incremental values and material, are stored in the memory. So if all of a sudden, you access an area of the file which is very far away from the previous location, it takes time as the new area, as well as differentials and material value of a few bytes is also copied to the memory. The box of files previously displayed is erased from the memory.

For performance improvements, you can go for the SSD, RAM with higher clock speed (must be compatible with the motherboard) as processor as well as the upgrade. However, please note that the process of accessing a file even as mentioned previously, but the speed will increase because of the higher bandwidth and the clock frequency.

  • Tecra 8000: monitor and the HARD disk does not work - does not start

    I have a laptop Toshiba Tecra 8000 given to me the year last by my uncle. I live in England, but it is and bought the PC in Italy. I do not know if this causes complications, but I thought it may be useful.

    Since I got it it occasionally did not display any image of all system startup, so if I have given some time and restarted it would start working again. Happening of bagan more frequently and now I can't make it work. I have conections and found that everything was in place. Then he doesn't seem to be turning on, however when I replaced the front LED cable seems to be turning on and although I couldn't hear much the CPU was luminous heat. I opened the drive and it gave once more, succeeded him and he still wouldn't start. I had purchased and replaced the screws on the heatsink around this area but I did not handle it with many other things.

    So now, I have a monitor that does not work and a gard drive that won't start... Any ideas?

    Thank you!

    Hello

    Could be either the card mother, CPU or ram. The processor when it goes bad or is not locked in place (have had this before, install the CPU but forgot to turn the lock, so he cannot move) the computer will act as its startup, don't give any error and stay on a black screen. Verify that the processor is locked in place. Then remove the ram and try a stick of RAM that runs on another computer. If you try the RAM and the processor do not always start, then chances are your motherboard is dead and must be replaced. Hope this helps and that solve you the problem.

  • After foolishly doing a system restore I can't find the files I thought I saved, and excel does not work.

    Excel is asking for the product key and I have the key to the offfice of microsoft, I bought. This is not correct.

    Hello

    System Restore makes the computer settings to an earlier point in time.

    System recovery is reinstalled the operating system configuration (new condition)

    System Restore and system recovery are often terms that are confused.

    Many people use both terms to refer to reinstalling the operating system; effectively use the machine to factory settings; It seems that you have done.

    Reinstalling the operating system wipe the hard clean of everything.

    If you have done this, you can try this free program to see what 'lost' data, it can find.

    Regarding your problem of Office:

    You don't say how you have reinstalled Excel.

    Are you try to put your paid for the Office product key in a trial version Office pre-installed?

    If so, uninstall the Office of judgment and reinstall your version of Office purchased the original media he came on, CD, DVD.

    And another thing: the product key on your computer is for the Windows operating system, not for the office.

    Office must be purchased separately. (you said, but I wanted to clear it for you)

    See you soon.

    I've lost the ability to copy files on my CD player.  When I drag and drop, the only authorized action is 'move' and it does not work.   I tried press and hold the CTRL key while dragging, and when I do that all the other disks show "copy" as the default action, but when I hover over the action CD player available only changes to 'pass '.   I ran the Microsoft Troubleshooting tool for CD/DVD players and he said that the media were not writable, but there is a blank CD in the drive.  Any ideas on how to solve this problem?

    Thanks, but the cd/dvd drive works well - I can burn a cd with windows media player for example.  the problem is that I can't copy files to it.   I can play CDs (haven't checked the DVD).  I can not do and could do before, is doing drag and drop files on it.  The only authorized action is "move".   This happens even when I click CTRL + do drag.   I can copy it to any other player, but the CD player, and when I hover over the "exemplary" drive CD goes to 'move '.

    have you tried using a different suite of cd/dvd burning?

  • My CD-ROM/DVD-Rom drive & the Bison Webcam built into my laptop. Does not work after I upgraded from Vista home premium to Windows 7 Home premium.

    My readers Optiarc DVD - RW AD-7530 ATA Device DVD/CD-ROM & the Bison Webcam built into my laptop. Does not work after I upgraded from Vista home premium to Windows 7 Home premium.
    Although of course, the CD-ROM drive worked during the upgrade.
    I noticed that when I turn firstly on the laptop, the last two lines of the front entry from Windows 7 are the following.
    PXE - E6i:Media Test Failure, Check Cable
    PXE - MOF: Exit PXE Rom
    During the audit of each Properties in Device Manager devices", I learned that they both work correctly.  In the list in the printers and the @Devices the only Webcam shown is also a "USB 2.0 Camera"
    Can someone help me please?
    Best regards
    John

    Besides what abdelhak says:

    The message of PXE boot that you receive when you start your computer has nothing to do with your CD/DVD-Rom drive. Your computer uses a PXE boot method to attempt to load Windows from a location on your network. Since you do not have this configuration, it is safe to ignore it. If it slows down the startup time of your system, contact your manufacturer and ask them for instructions on how to "disable PXE Network Boot of the BIOS.

    Hope this helps,

  • Error blue screen STOP: 0x0000007e. I powercycled the sys, unable to choose for sure (keys do not work when you try to select a mode) sys is trying just to go back to the blue screen. Help, please

    STOP: 0x0000007e (0xc000001d, ox8537008 0xba4c3508 0xba4c3204) and the system would not come to the top.

    Error blue screen STOP: 0x0000007e. I powercycled the sys, unable to choose for sure (keys do not work when you try to select a mode) sys is trying just to go back to the blue screen. Help, please

    Symptoms: Booted computer, loaded the raid drivers and showed at the start screen XP for half a second then to BSOD with a Stop error Code 0x0000007E - see also a lot of users (0xC0000001D, 0 x-, etc.) as well.

    Solution:

    1 boot from your Windows XP CD and start the recovery console. You may need to press F6 while RC loads in order to load the SATA drivers. you will have a prompt c:\WINDOWS to the console.

    2. type: CD $NtUninstallKB977165$ \spuninst (it's the update, I had to uninstall to get out of the boot loop, other updates can be uninstalled by changing the name of the directory to $NtUninstallKBCODE$, where KBCODE is the code KB)

    3. type: BATCH spuninst.txt

    4. type: exit

    Don't forget to configure your system to boot from the HD before resuming. I hope this helps. Saved me a lot of hassle today.
