So, how to solve the :data error (cyclic redundancy check): issue has become a problem annoying many computer users. And here, before fixing this issue, we think you should know what the "cyclic redundancy check" is.

What is cyclic redundancy check?


A cyclic redundancy check (CRC), invented by W. Wesley Peterson in 1961 and further developed by the CCITT (Comité Consultatif International Telegraphique et Telephonique), is basically an error checking technique used for data verification. It is used by computers to specially check the data on your disks (hard disks like your hard drive and optical disks like CDs and DVDs).

However, what should you do if you receive the warning: data error (cyclic redundancy check)?

Drive is not accessible, data error (cyclic redundancy check)

Now, let's see a true example:

I was transferring files from my external hard drive (Seagate, 250gb) when the power shut off. When I use the drive again, I got this cyclic redundancy error and windows suggest to format the drive. I can't do it now since I have many important files. I tried disk check but the drive is inaccessible (even in cmd prompt). Any suggestion please?

Cause
This issue may be caused by various factors, including registry corruption, a cluttered hard disk, an unsuccessful program installation, misconfigured files, and more. Nevertheless, whatever the reason, the cyclic redundancy check error is a serious one and must be addressed to avoid potential data loss.

In fact, people that successfully deal with this cyclic redundancy check error do 2 things very well.

First, they completely recover lost data from the inaccessible drive with CRC error.

Second, they fix data error (cyclic redundancy check).

Now, you might be wondering:

"How do I successfully recover lost data and completely solve this error?"
