This error is usually preceded by another warning message that tells you that you must format the device in order to be able to use it. If (obviously) you say you Don't want to format it and try to access it, that's when this error appears that we show you.
The second situation in which this problem appears has to do with the initialization of a new SSD that you have just installed and you try to configure (it also happens with external drives, and in fact it is quite common on these). For some reason, Windows is unable to initialize the device and therefore does not allow you to access its content.
Cyclic redundancy or CRC error testing is an error detection technology that is frequently used in storage devices to detect accidental data changes. It is a kind of data verification method to check the accuracy 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 inevitable incidents, such as operating system log corruption, failed program installation, computer malfunction, etc. Generally, when you receive this problem it has to do with files hosted on the device.
How to fix cyclical redundancy error
In addition to preventing us from copying files and accessing device data, this cyclical redundancy error will potentially cause a computer file system failure that could lead to data loss. It is therefore necessary and urgent to solve it as soon as possible, so let us see what we can do about it.

Method 1: use CHKDSK
The CHKDSK utility integrated into Windows will be our best partner in solving these problems, as it automatically searches for and repairs any errors in storage drives and especially in the file system.
In all probability you will receive a message like the one we show you at the beginning of this section, telling you that it cannot be executed because the files are in use, and that if you want CHKDSK to run automatically the next time you restart the computer. Obviously, you have to say yes by pressing the letter Y on your keyboard and then enter, and then you have to restart the computer for CHKDSK to do its job.
This check can last quite a long time depending on the size, speed, and amount of problems you encounter in your storage unit, but you simply have to be patient and wait for it to end. In all probability, this will simply solve the cyclical redundancy problem on your device (and some other that you might potentially have).
Method 2: the disk check tool
Windows also has a graphical interface to check the status of the disk, and although it is not as forceful as the previous one we have told you about, it can be equally effective for this type of problem and especially if the problem is in an external drive with USB connection. To make use of it, follow the following steps:
When the system detects the problems, in this case it will ask you if you want to correct them automatically (unlike CHKDSK that corrects them without asking you). Windows may also directly detect that the unit has problems, in which case instead of "browse Unit" you will get the option "repair Unit" directly. In any case, the process is the same, and you simply have to wait for the system to automatically fix the problems.
In the event that neither of these two methods works and you still have the same problem in your storage unit, there is a chance that it has been definitively damaged, although in the event that the problem is due to corruption of registration it is worth trying to restore the system to an earlier point to check you out.
