On a Win 8.1 machine, I was notified that there was no HD present. Even the old WD Lifeguard diagnostic program agreed. But later, I was able to boot into Safe Mode and after changing from Selective to Standard Startup, was able to boot Windows normally.
Do the drive shut itself off/make itself invisible? And then turn itself back on/become visible??
Hi pikov, welcome to the WD Community. There might have been a connection problem with the drive, but as long as the DLG test completes successfully the drive should be OK.
Could you say a little more about a “connection problem”? Would that be a physical (i.e, cable) connection or perhaps a handshake (do they still do that??) problem?
And how would it self-correct?
OK, the DLG failed the first time and then after several reboots, Iran it again and it passed.
I sat down at my desk and saw that my screen was frozen with an error message that said it was collecting information about an error. It was stuck at 0% and, in small print, mentioned “KERNEL_DATA_INPAGE_ERROR”
I turned off the power and turned it on, and it booted normally.
