I have successfully updated the firmware (WD don’t make that easy on Linux). It still shows the same Error Information Log Entries on the quick test. Running the long test now, but presume results would be the same.
Would you RMA this drive?
EDIT: reading around a bit, this seems fairly common and often get +1 error log per boot. This may have been the case with mine with something misconfigured. Since the reinstall the number has not been going up, so I’ll see how it goes for now.
Thanks to all who helped in this thread, as well as the thread on how to update firmware on WD drives.
