Is my drive a goner?

yup thats exactly what I meant :)…

I have same problem with trying to guess what color it is… if yellow or white… well the only way to know if its upgrading firmware is to leave it over night turned on and if in the morning its still white/yellow then its time to either send it for RMA (back to WD so they can fix it) or take it apart and rewrite rootfs partitions… there is actually guide to unbrick the device without taking it apart

But I never tried it… taking it apart is quite a challenge but then it just get easier… well you will need SATA to USB cable so you can connect the drive to PC (with linux on it)
