If
you keep getting the error cyclic redundancy check error (CRC), you
need to understand what it is first before fixing it. This is a
method used by computers to check for errors in a hard drive or
optical disc (CD or DVD). The error message appears when the hard
disk or optical disc is corrupted.
Make
an Assessment
If
the error is caused by your hard drive, it is probably due to data
not being written properly on the disk. This is usually due to a
corrupt or problematic operating system, but it can also be due to
sudden power outage.
Fixes
and Solutions
If
you experience the problem with your hard disk, run Chkdsk or
scandisk. Go to My Computer and right click the hard disk that is
giving you the error. Choose Properties and run the disk checker.
After running the disk checker you can find its logs by right
clicking My Computer and going to Manage then Event Management and
Application
logs.
If
you can’t access Windows or the GUI becomes inoperable, then
Windows can’t do the check on its own. Your alternative is to use
the command line.
To
use the command line, do the following:
Step
1
Run
CMD using your rights as an OS admin.
Step
2
Type
the following:
chkdsk
C: /f /r ( 'C' refers to the affected drive; change if necessary)
Step
3
Type
in the same prompt:
DiskPart
Step
4
Run
the "rescan" command once the utility has been loaded. This
utility will start looking for any disks that were installed in your
computer and attempt to fix them.
If
the error is caused by an
optical disc,
you have other options. If the error appears when you try and burn
data, use a lower speed. Some computers and operating systems produce
those errors when burning at high speeds.
CRC
Cyclic Errors and Data Transfers
Those
CRC errors often come up when the mathematical processes used for
data transfers fails to work. When the computer performs the CRC
check, it will verify if the data being transmitted is in good
condition. If the error message appears, it is due to the fact that
there is a problem with the data being transferred or there is a
problem with the storage device.
CRC
Errors, CDs and DVDs
The
error often occurs when you try to copy data to and from a CD or DVD.
Before the error message appears, there will be a whirling or
grinding noise coming for the CD or DVD or your computer will slow
down. The whirling sound is due to your computer’s attempts to read
the disc numerous times unsuccessfully.
If
after repeated tries it doesn’t work, the CRC error message will
appear. Note also that this error message will appear if you try to
get a file from the web that was not downloaded correctly. Sometimes
this error message will also appear if an application or the
operating system crashes.
If
the problem is the disc, use a disc cleaner to remove the dirt. That
should do the trick. If not, then try cleaning the disc drive, it
might be dirty. Either one should resolve the problem.
As
stated, the problem could be due to a faulty hard disk. But most of
the time the error cyclic redundancy check error is due to the DVDs
and CDs not being read correctly.
