With computers, we all face some problem or the other very often. Some are simple ones easily solved, while some are more complicated and take a longer time. It may be quite frustrating when you come across such problems and do not know what to do. For example, your trouble may start when you have to transfer files from your DVD to the computer, and you encounter a CRC error. No need to worry, for here are a few details to help you.


CRC [ cyclic redundancy check] is generally used in hard disk and storage devices where it can help check the data stored. When it is faulty, you get a CRC error. CRC errors can occur when you want to transfer files from external sources maybe a CD or DVD. This shows that the data to be transferred is damaged. CRC can occur even when there are repeated attempts to transfer files. But all these should not pose much of a problem, because solution to this error is quite easy.


In order to solve this problem, you require to possess clear data, that is to say the data file must be free from any sort f damage external or internal.

If any kind of scratch is found on the front, then CRC error is bound to happen. You need to keep the surface absolutely clean. You can always use any lint-free cloth or alcohol or better still use a cloth dipped in a mixture of warm water and soap solution to clean externally.

But if the problem is due to internal damage, then you need to download Jfile recovery software which is the right choice to correct CRC errors. Please note that you have to have Java on your system if you want to use the Jfile recovery. Its results are immediate and free!


  1. CRC errors on startup are actually a Vista SP1 bug. Microsnot was offering free support for this for a while but not sure if they still are. Its a pain in the arse to repair if you aren’t extremely tech savvy and used to using command prompt.

  2. Easy way to fix this and will termine whether it’s a windowsd problem reading the disk. I’ve the same issue using windows 7 on a 1tb external hard drive. Loading into Linux, I can easily access the data on my drive. So the issue is not the disk, but windows being able to read. Simple test will terminate the problem. Download any linux iso, burn onto cd. Load Linux from the CD, no install required(this can be done without installing Linux permanently)You should see the data on your drive instantly. Linux doesn’t use NTFS and this is where it can fail in windows.

  3. i am getting the error 0x8007045d when i try installing windows 7 on my hard drive i don’t have any data on it and i am not able to format it also please help!!!!

  4. I click on the link posted by you but it does not seems to be working now. When i plus my external hard disk to my laptop, it asked me to format and CRC error pop out. How can I recover my data? Are the other ways that I can use since the link is not working now.

    Hope to hear from you soon! Thank you very very much! :)

  5. Hello, I clicked on the weblink in your post but I got this error “Problem Error Failure”. Is there anyways that I can download this free software or other freeware that I can used to recover my precious data?

  6. before formatting my laptop i transwered all data to external hard disk, after formatting while transwering the data back from hard disk to macine the error comes redundancy check in most of the folders specally in pictures.
