I've read every single question related to this topic and really haven't gotten any answers.
These suggestions:
- Try different cable.
- Look if cable connector is connected good with connector on mainbord/harddisk.
- Try a different controller connection.
I've tried a different cable and used a different computer (which is a brand new build), and still get this error on multiple hard drives.
What exactly does this error mean? Does this happen to all hard drives over time? It's currently happening to my Samsung SSD 250, WD 2 TB, and my WD Green 500 GB. What is the deal. 2 have 1 error, and other has 4 errors. Is this actually an error.
MY SSD drive is my main operating system, and from time to time i get random blue screens. Could this be the cause of this?
Answer
Basically CRC errors are caused by bad sectors or because the drive is not communicating with the computer. CRC tests the data pattern that's on the disk and looks for "illegal" patterns, meaning that the data has been corrupted. There's several reasons this could happen and those include both physical errors (bad sectors) and logical errors (like a power outage that scrambled things).
The ultra DMA CRC error count indicates problems with the transfer of data between the host and the disk. They can't be caused by software, and they don't indicate a problem with the disk itself. So personally I would reseat all of the drive cables and if the numbers continue to climb, then I'd try using different cables.
If you're concern about the health of the drives, you can run WD Data Lifeguard Diagnostics tool on your HDDs to see if any errors or bad sectors are detected. In case you decide to run an extended test backup your data first, because if the software finds any problems it will try to fix them automatically. You can download it from here:
