April 7Apr 7 Community Expert Just UDMA CRC ERRORs, these are connection problems not disk problems. Click on 👎and Acknowledge, it will warn again if it increases.
April 7Apr 7 Community Expert I didn't notice anything currently in the Diagnostics. The drive firmware records CRC error when received data is inconsistent (checksum). It won't necessarily cause an I/O error since the data is resent. And I/O errors won't necessarily cause CRC error since the drive may not receive any data to checksum.That number will never reset. If it continues to increase, especially if it increases rapidly, then you need to figure out why. Could be just a loose connection, or bad cable.
April 7Apr 7 Author Notice that SMART self-test had started. Could this indicate that there is something wrong with this hard drive? thecave-diagnostics-20260407-1229.zip
April 7Apr 7 Community Expert That just means a test is running; if it fails, then there is a problem.
April 7Apr 7 Author I noticed the test was started automatically. Something about the drive is causing red flags in the system. I am a little worry that I probably will have to do a warranty replacement for the third time on this drive. ( about 2 years warranty left on drive).
April 8Apr 8 Community Expert Never heard of self-test starting automatically. Post a screenshot of the Self-Test section
April 9Apr 9 Author Okay. I did not start the smart test. Hopefully I will learn more to what happen with the smart test.
