Is the hard drive partitioned and formatted yet?
If not do this:
1. Connect the USB enclosure to the computer and turn on the computer.
2. Go to Control Panel - Administrative Tools - Computer Management. In the Computer Management window click on Disk Management.
3. In the Disk Management window you should see 2 hard drives. Disk 0 – that’s your primary hard drive and Disk 1 – that’s the hard drive in the USB enclosure. For the Disk1 you’ll see the HDD size inside the bar and also it should say Unalocated. It means that the new hard drive is not partitioned and formatted.
4. Right click on the unallocated space and click on new partition entry, the wizard for creating a new partition on the hard drive will appear. In most cases you should chose: Primary partition, partition size would already in there (entire drive), assign any free letter or leave it default, file system NTFS (default), check the Perform a quick format (faster) box, NEXT and FINISH. It might take some time. You’ll see that the LED on the USB enclosure (if you have any) will start flashing.
5. After it’s done, you should see that Disk1 says: New Volume, HDD size, and Healthy.
Now, if you go to My Computer you should see the second hard drive and you can use it as a regular drive.
