on Redundancy Check
Redundancy Check is
commonly known as Cyclic Redundancy Check (CRC). It
is a code which evaluates the function of any program
in the computer. These check codes usually deal with
the hardware. This code follows a mathematical logic.
Any noise within the computer may lead to redundancy
check and all the transmission channels will
be checked. This function was invented by W. Wesley
Peterson in the year of 1961.
Redundancy Check comes up when there
is issue regarding CD/DVD. Data stored on a CD/DVD cannot
be read when this happens. The CD drive will spin and
but it will become slow while checking the data. We
may face the same issue if the system crashes or if
any software is partially installed. An error like ‘Corrupt
Zip file’ or ‘This is not a valid Windows file’ indicates
the same. It is suggested to change the program for
downloading softwares in order to get rid of this. However,
redundancy check may differ in case
of CD/DVD. Usually, these errors come up with a grinding
noise and when system fails to read the content from
a CD, this issue comes up. We may try to check the cables
attached with the CD drive but the better way could
be “disk cleaning”. If the CD/DVD is not properly burned,
then also issues take place. People who use USB CD drives
may face the same issue.
However, if nothing helps then we may perform simple
steps to avoid redundancy check. We
need to locate the “Computer” icon on the main screen.
Now, we need to double-click the hard drive which is
showing the redundancy error. Here we need to click
on the "Tools" and choose "Check now".
It will scan the drive for redundancy check.
It will be solved and we are through with it.
