Having trouble seeing a newly attached USB drive or memory stick?
The reason usually is that Windows renamed the drive to a letter that is already in use. This can if you have several thumb drives or external hard drives attached, and multiple mapped drives. Another reason is having multiple primary partitions created AFTER you have attached a USB device.
To fix this issue you will need to find the drive and then rename it. Here are the steps to follow outlined below:
1. Right-click on My Computer and select Manage.
2. From the Computer Management screen, select Disk Management.
In this window you should see all of your connected physical drives, their format, if they are healthy, and the drive letter.
In this instance I am going to change the drive letter of my SecureGuard USB drive.
3. Right-click on the drive in the list, and from the resulting menu select “Change Drive Letters and Paths…”
4. Click on Change so we can change the drive letter.
5. Select a new drive letter from the drop down list,
Preferably the one that you usually use for this drive.
6. Click Yes on the confirmation screen and you are done
If you have auto play enabled you will get the normal pop up dialog asking what you want to do.
Please leave a comment if this has helped you out.
