    Solved Multiboot issue

    btw anyone can try commands fixboot (driveletter) and fixmbr from recovery console too as a STEP 2b

    Solved Multiboot issue

    I have projects on it, when i reinstall windows, program and plugins im risking that i lose some parts of my projects, thats the only reason :)

    Solved Multiboot issue

    luckily i had figured it out :) I'm not saying it's the right way to do it, but the problem has been fixed. First of all, I want to say that there were no boot files ntldr boot.ini NTDETECT.COM on the toshiba disk, I also copied AUTOEXEC.BAT CONFIG.SYS IO.SYS MSDOS.SYS to be sure. Here I will...

    Solved Multiboot issue

    Hello, I have two HDDs in my computer, old Seagate with bad sectors and new Toshiba. Each disk contains Windows XP operating system. When I remove the Seagate hardware, my computer cannot boot into Windows on the Toshiba HDD. I tried the fixboot c: and fixmbr commands from the Windows CD, but...

    RAM recovery

    I just remembered hearing about the HC effect in relation to EEPROM, specifically: Hot carrier injection (HCI) is a phenomenon in solid-state electronic devices where an electron or a “hole” gains sufficient kinetic energy to overcome a potential barrier necessary to break an interface state...

    RAM recovery

    I was pleased that there were people who were able and willing to advise me on this matter, and I would welcome if anyone else would like to comment on this topic :)

    RAM recovery

    I have read an article about "Hot-carrier injection" on Wikipedia, which is full of interesting informations. One of the things I have confirmed is that to become “hot” and enter the conduction band of SiO2, an electron must gain a kinetic energy of ~3.2 eV. For holes, the valence band offset in...

    RAM recovery

    Can't be high energies created for example by short current peaks or by current noise? If there is no other cause for creating high electrons, except temperatures, good cooling could be the solution, what you think?

    RAM recovery

    This mean the temperatures would have to be around 150 ° C to create excess charges, or what temperatures would have to be to create them?

    RAM recovery

    In terms of safety and privacy, this could be important, for example, for searching of cryptokeys. Just high temperatures cannot be a risk? 4.2. Hot Carriers High-energy electrons can cause other problems as well. A very obvious one is that the device heats up during operation because of...

    RAM recovery

    Thank you for Your answers, I would like to respond to the posts The solution could be scrambling that started to be used with DDR3, You can read more in the document from 2017 - Cold Boot Attacks are Still Hot: Security Analysis of Memory Scramblers in Modern Processors I can confirm that...

    RAM recovery

    Yes, I need to clarify something if I can ask you. How did you mean it that you personally doubt it ever comes into play anywhere? You want to say that this is a relatively complex process so no one will deal with it, or did you want to say that there will be not enough memory cells for...

    RAM recovery

    Will ram cooling prevent in creating of excess charges in Yours opinion or do you think it may rather harm?

    RAM recovery

    Im just asking if there is a risk with any genertion of DDR that electrons overcome the potential barrier and will be accelerated into the gate oxide and stay there as excess charge at typical workload, and how much this phenomenon would have occurred in these DDR RAM generations in normal...

    RAM recovery

    I don't know if I understood it, but if RAM module remains at low temperatures, it should not occur that the energy of electron exceeds the average thermal energy of the memory dices or conducctor. Isn't there any electro engineer on the forum that could help?
