Today though it disappeared from Finder on my Mac. When I check is I noticed the light is solid red and it’s ‘stuck’ in a cycle where it makes a sound like the drive is starting to spin and then double beeps 4 or 5 times (one low beep followed by a higher beep) and then the process starts again.
I’ve tried turning off power, plugging the power cable in somewhere else, unplugging and replugging the network cable, another network cable, plugging the network cable directly into the PC - all to no avail.
I worry my drive is done and I’ve lost all data on it.
If it is not the cable and your drive gets efficient amount of power from USB port then, either heads got stuck on platters, or your drive is having problem with bearing assembly. Bearings on WD drives are solid and almost never an issue, so I’d say chances are your drive got stuck heads. Just like brakes on the car.
