Hi Matt,
"Was the drive on, and working, and then it stopped working?"
Yes, the blue light was permanently on and then it started flashing and the drive disappeared,
"Did PG support say what the flashing blue light means for this model? "
PG support haven't replied yet
"I assume you rebooted and tried it again."
Yes, I've rebooted and tried 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."
I've got lots of devices connected but I don't think that this is the problem... The intermittent light appears even when it isn't connected to the computer.
I really appreciate your help, Matt but I'm due to take the wife out for dinner and if I don't switch off right now, the USB drive won't be the only thing that's not working!
Many thanks again
Mark
