Fixing Cyclic Redundancy Check Data Errors
Cyclic
redundancy check (CRC) in short is a data verification method that your
operating system uses for checking the information on your storage devices,
such as the hard drive and CD/DVD ROM Drives. This cyclic coding process is
utilised because of the many it advantages it has, such as:
·
Cyclic
codes are very adept at detecting single and double bit errors and also odd
number ones also.
·
CRC
codes can very easily be implemented into both hardware and software.
·
When
utilised in hardware, they tend to work very fast.
A
cyclic redundancy check error can occur for a number of different reasons. These
kinds of errors tend to be rather severe, and can lead to further damage to
your hard drive typically, if not quickly addressed. Hard drive failure being
one of several risks that your storage device could inherit. Fortunately, there
are several things that you can do to address this problem, all of which I
intend to highlight in this article, so please continue reading.
What Causes Cyclic Redundancy Check Errors
As I
previously mentioned, these errors can be caused by a number of different
things, such as registry corruption, cluttered data within the hard drive,
failed installations, misconfigured components and files, and much more. Cyclic
redundancy check error is a serious issue and something you’d want to address
as soon as possible, as what initially may have been a simple fix could very
easily turn into a major problem.
In
addition to those reasons, other reasons why this error may occur include:
·
The
data cable between the hard drive and motherboard is either damaged or faulty.
·
The
read/write head on the hard drive is physically damaged.
·
Cables
inside the computer have come loose.
Other Causes
There
are those rare circumstances when a cyclic redundancy check data error is
actually caused by a driver issue. However, in most cases, the CRC error will
usually occur right after the end user has installed a RAID controller, not
months or weeks later.
Another
thing to keep in mind is that, even brand new storage devices are sometimes
shipped out defective. There are many reports of end users purchasing damaged
components. Even I have had such experiences in the past.
There are
so many reasons why this error may be occurring on your computer. The error
could just as easily be hardware related. In the event that your hard drive (or
other storage device) is physically damaged, the only way to repair it would be
to physically replace the drive. There are many backup tools that you can use
to transfer the data to the new drive.
But
let’s assume that the error is software related, as it typically is, 80% of the
time. There are two things that you should immediately adopt when fixing this
problem. They are the following:
Use Check Disk
Check
disk is a built in Windows repair tool, designed to scan and repair errors on
your hard drive. Check disk is capable of locating and repairing those small
data corruption issues on the drive that may be causing the cyclic redundancy
error. You can run this tool by doing the following:
1. First,
boot into your computer with full administrative rights.
2.
Then press Windows Key + R, type … into the Run Command
box and click on OK (or simply press
Windows Key + E).
3.
When My Computer loads up, right
click on the Drive(s) that you are
receiving the Cyclic Redundancy Check
error on, and select Properties.
Note: If you receive the cyclic redundancy check
error when attempting to load data from a CD or DVD disc, then the cause is
most likely due to a scratch or dust on the disc itself. Consider cleaning the
disk using a soft cloth. If that doesn’t work, you may want to consider
investing in a CD repair kit.
4.
Once your Hard Drive Properties
applet loads up, click on the Tools
Tab, and then click on Check Now,
under Error-checking.
5. A
small Check Hard Drive applet will
appear; from here you’ll want to tick the box to Scan for and attempt recovery of bad sectors and then click on Start.
Note: Since cyclic redundancy check errors are
typically caused by damaged or corrupted sectors on your hard drive, you need
only tick the box next to that option. That said you can select automatically fix file system errors,
as this could potentially improve the performance of your hard drive.
6. A
notification should appear asking you whether you could like to schedule the
scan for the next time you reboot the computer. Select yes, and then restart your system.
Note: The entire scan process may take several
hours, depending on the size and amount of data on your hard drive. So make
sure to run this scan in your spare time, as you will not have access to your
computer for a considerable length of time.
If you
start to encounter these cyclic redundancy check errors more and more over
time, then that is a good sign that your hard drive is nearing the end of its
life cycle. You’ll want to replace the hard drive before it actually fails, as
you will lose all the data on the drive when that actually happens.
There
are a number of third-party disk utility tools that you can use. When Check
Disk is unable to repair the error on your hard drive, a third-party solution,
may be your only solution.
Some
popular options include SeaTools and HDDScan, both of which are proficient,
able to scan, detect and repair a plethora of issues on your hard drive. So definitely
check those tools out.
Many
of these disk utility tools are available for virtually every version of
Windows, so compatibility shouldn’t be an issue for you.
If you
try any System Cleaners, make sure the product was developed by a reputable company.
Many of these tools tend to have disk utility features, which are capable of
repairing and optimizing your hard drive, so definitely a good option there.
