results when the file fails this check, meaning that some part bad checksum spybot of the data no longer corresponds to the original. If your data fails a checksum verification, checksum error in the encrypted file winrar it usually means that you need to replace it from a backup or otherwise reconstruct the affected file.FunctionIf, for example, you have a list of numbers you https://www.safer-networking.org/faq/why-do-i-get-a-bad-checksum-error/ need to transmit to a coworker, and need to make sure he writes down the numbers exactly, you need to have some way of verifying that he got everything correct. One simple method you could employ is adding up your list of numbers and writing down the sum. Once he has copied the list, https://www.techwalla.com/articles/what-does-bad-checksum-mean he can add his numbers up and compare his sum to yours. If the two totals do not match, it is a sure sign that he made an error. This is a very basic example of checksum verification.Computers and ChecksumsChecksum in computers is more complicated than simply adding a list of numbers together, but it follows the same principle. In most cases, the system uses a much more complex mathematical equation known as a cryptographic hash. This produces a unique output based on the input, and computers can use hashes to verify large quantities of data very quickly. The complex nature of the cryptographic algorithm means that any small amount of variance in the data produces a significant difference in the checksum, and if the generated number does not match the expected value, you receive a bad checksum error.Bad ChecksumsThe most common source of checksum errors involve your computer’s BIOS. This nonvolatile portion of your computer’s memory stores important infor
the CMOS Checksum Bad Error, hence they can be handled effectively. The Error Explained A checksum is computed as an error detecting code to guard the BIOS settings stored in the http://www.tech-faq.com/cmos-checksum-bad-error.html CMOS memory. The CMOS Checksum Bad Error is an error that occurs when the CMOS https://blog.udemy.com/bios-checksum-error/ values turn out to be incorrect. The CMOS memory stores a specific value normally to guard the BIOS software. Each time the computer is booted, this value, which is a number is checked against the stored value in the CMOS memory. If these two values are different, it causes a CMOS Checksum error message. If these values checksum error are the same, the computer boots normally. Each computer usually deals with the CMOS Checksum Bad Error differently. Some computers warn the user and continue to boot up using settings in the CMOS, while other computers might warn the user and use the default settings in the BIOS as the correct settings and carry on with a normal boot or reboot. Usually, the strategy the computer employs is stated in the error message. bad checksum error Causes of CMOS Checksum Bad Error There are usually three main reasons that a CMOS Checksum Bad Error occurs. They include: CMOS Battery may not be functioning properly. The battery life may have expired. The user or a virus may have updated the BIOS. The computer may not have been shut down properly e.g. shutting off the computer's main power without first shutting down the computer (MS Windows requires the computer to be shut down before the power is shut off). Solutions to CMOS Checksum Bad Error The CMOS Checksum Bad Error can be fixed easily by following the listed steps carefully. CMOS Battery May Not be Functioning Properly If the user suspects that the CMOS battery is not functioning properly, he/she can easily change it. Before changing the battery, reboot the computer to make sure that the error still exists. If it does, go into the CMOS and write down all of the settings. If all the settings are lost, they can usually be retrieved from the computer manufacturer. Now locate the battery and remove it. Consult the computer manual or technical support to remove your battery (the battery is flat, shiny silver colored, and coin-shaped) if needed. Take down the CMOS battery’s information such as volt, size, etc. Replace the old battery wi
2014 by Alex Barbos A BIOS checksum error is one of the most common errors you can encounter when you build your own computer, perform a hardware upgrade or attempt to bring back to life a computer that hasn’t been used for a long time. If it sounds like a scenario that’s not very likely to happen to you, think again, as computers became so un-complicated that you don’t need to be working at NASA to know how to upgrade or even build one yourself; in fact, learning how to build your own computer is as simple as taking this online course, so the possibility of coming across a BIOS checksum error one day is higher than you think. The error indicates that the BIOS is incorrectly configured or corrupted, preventing the computer from booting normally; unlike operating system errors or software errors that occur after your computer is up and running, a BIOS checksum error will render it inoperable right after you power it on, so it’s no wonder this type of error can seem like something really serious. Fortunately, it is not as scary as it seems, and fixing it is quite easy. BIOS Basics In order to understand what triggers the BIOS checksum error, what the error means and how you can fix it, it is necessary to understand what the BIOS is and how it works. Simply put, the Basic Input/Output System, or BIOS, is a program that checks if all the components necessary for the computer to run are present; if everything is ok, the BIOS gives the processor the necessary instructions on how to proceed and load the operating system. Before the boot code in the BIOS is executed, though, the BIOS data is checked for authenticity by comparing one of its values, known as a checksum, against a value stored in a memory chip called CMOS; if the values match, it means that everything is working correctly, so the boot code is executed and the computer starts normally. However, if the checksums do not match, it means that something interfered with the BIOS, so the comput
