|I've assigned a different drive letter and the external disc is recognised in disk management as Disk 1 Expansion Drive (G) - Healthy (Active). It has a blue bar indicating that it is formatted but still doesn't show in My Computer.|
When I click on the blue bar I have the following options:
Change drive letter and paths
The option to mark partition as active is unavailable. No drive with the letter G shows in My Computer. In System Device Manager, the external drive's properties show that it is enabled and working properly and that its Location is 0.
If I right-click on the small rectangular label to the left (designated Disk 1) I get the options of Properties and Help. Clicking on Properties shows that "This device is working properly" and is enabled. Its location is given as "0" although I have given it the drive letter "G", as which it shows up in "My Computer Information - Hardware" as "Local Disk (non-partitioned)".
There is no option to Initialise, only to Format. When I try this I eventually get the message: "The operation did not complete because the partition or volume is not enabled. To enable the partition or volume, restart the computer." If I leave the drive plugged in and restart my computer the system will not reboot as it seems to be trying to boot from the (empty) external drive.
