Hi,
Do you see any yellow\red exclamation mark in device manager?
I would suggest you to open Disc management and check if the drive is detected there, here are the steps:
1. 1. Open Computer Management by clicking the Start button, clicking Control Panel, clicking System and Security, clicking Administrative Tools, and then double-clicking Computer Management. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
2. 2. In the left pane, click Disk Management.
If it the hard drive recognizes in the disc management and if there is no drive letter assigned, I would suggest you right click on the drive and assign a drive letter and check if it helps:
1. 1. Right-click the drive to change, and then click Change Drive Letter and Paths.
2. 2. Do one of the following:
· To assign a drive letter if one has not already been assigned, click Add, click the letter that you want to use, and then click OK.
· To change a drive letter, click Change, click Assign the following drive letter, click the letter that you want to use, and then click OK.
· To remove a drive letter, click Remove, and then click Yes to confirm that you want to remove it.
