I bought a new MyBook Studion Edition II, 5Tb drive. I connected it, turned it on and W7 Pro does not mount it – I do not show a new drive on my system. When I go into Computer Management/Device Mamager, I see the drive, and when I switch to Computer Management/Disk management, I see it also, but without a drive letter. (It shows as 3 partitions, 200Mb, 5588.7- Gb, and 128 Mb. All healthy.)
But nothing I do makes the disk actually available. I’ve tried with both USB2 and Firewire 400. I’ve tried uninstalling the driver using Computer Management/Device Mamager and reconnecting it and lettingt he driver reinstall. I’ve rebooted it and made sure I’m up-to-date on Windows Update. All no luck.
