That's too bad, Mark. My 1.5 TB drive has been running for several days without a problem. I installed it the same way you did.

Was the drive on, and working, and then it stopped working?

Did PG support say what the flashing blue light means for this model?

I assume you rebooted and tried it again.

There is an obscure Windows problem if one uses too many USB devices, not at once, but over time. Have you plugged lots of devices in during the life of this machine, and plugged the same device to different ports? If so, write back and I'll give you something to try.
