PCs are, in one way or another, prone to many errors. Fortunately, most of the time these errors can be fixed and with a little work and research we can fix them. For that, we are here with this article, because if your problem is that you cannot access data from an SSD (and be careful as this does not happen with traditional mechanical hard drives) due to an error data (cyclic redundancy check) you will tell you what you need to do to fix it.
Cyclic redundancy check error, why does it appear?
In most cases, there are two reasons why your SSD may be inaccessible showing you this error. In the first situation, you will see that the unit is not accessible and a window similar to this appears (oddly enough, it usually appears in English even if you have the operating system in Spanish):
Usually, this error is preceded by another alert message that tells you that you need to format the device before you can use it. If (obviously) you say you don’t want to format it and try to access it, that’s when this error pops up that we show you.
The second situation in which this problem appears has to do with initializing a new SSD that you just installed and are trying to configure (this also happens with external drives, and in fact it’s quite common. in these). For some reason, Windows fails to initialize the device and therefore does not allow you to access its contents.
Cyclic redundancy or CRC error checking is an error detection technology frequently used in storage devices to detect accidental changes to data. It is a kind of data verification method to verify the correctness of the data contained in the storage device. Obviously, this error occurs when the CRC system detects that there is a problem.
This type of error can also be caused by other unavoidable incidents such as corruption of the system registry, failure to install the program, improper shutdown of the computer, etc. Usually when you get this issue, it is related to files stored on the device.
How to correct the cyclic redundancy error
Besides preventing us from copying files and accessing device data, this cyclic redundancy error will potentially lead to computer file system failure which can lead to data loss. Therefore, it is necessary and also urgent to resolve it as soon as possible, so let’s see what we can do about it.
Method 1: use CHKDSK
The CHKDSK utility integrated into Windows will be our best ally in solving these problems, since it automatically searches for and repairs any errors in storage units and in particular in the file system. To do this, you need to open a Command Prompt window (right click on the Start button -> Command Prompt (administrator) and run the following command replacing the letter C with the letter of the drive you are having trouble with.
chkdsk. c: / f / r / x
In all likelihood, you will receive a message like the one shown above, stating that it cannot be run because the files are in use, and that if you want CHKDSK to run automatically the next time you restart the l ‘computer. Obviously, you have to say yes by pressing the letter Y on your keyboard and then ENTER, then you have to restart the computer for CHKDSK to do its job.
This check may take some time depending on the size, speed, and number of issues with your SSD, but you just need to be patient and wait for it to finish. In all likelihood, this will just fix the cyclic redundancy issue on your device (and any other you might have).
Method 2: Check Disk Tool
Windows also has a GUI to check the status of the drive, and while it’s not as powerful as the previous one we talked about, it can be just as effective for these types of issues and especially if the issue is is in an external drive with USB connection. Open Windows File Explorer (WIN + E key) and find the drive you cannot access; then right click on it and select Properties.
In the window that opens, go to the Tools tab then click on the Check button located under the heading Error checking.
A new window will open, maybe like the one we are showing you now saying that no errors were found but that if you want to examine the unit anyway. Do that, click on “Browse drive” and let the application do its job, which as usual is almost always automatic and does not require you to intervene at all.
When the system detects the problems, in this case, it will ask you if you want to fix them automatically (as opposed to CHKDSK which fixes them without asking you). It is also possible that Windows directly detects that the drive is having problems, in which case instead of “Browse drive” you will have the option “Repair drive”. In all cases, the process is the same and you just have to wait for the system to automatically take care of fixing the problems.
In case neither of these two methods works and you continue to have the same problem in your storage drive, chances are that it has definitely failed, although in case the problem is due to a registry corruption, it is worth trying to restore the system to an earlier point to be sure.
