WD Black SN770M

I installed the 1tb version in a MicroSoft Surface Pro 8 and had a lot of trouble with Stop Clock WatchDog errors, reboots, etc… One of MicroSoft’s power options to save power is to turn off the drive when it is not in use. Turns out that was my problem. You need to make sure power options doesn’t turn the drive off.
