I cannot get a Targus card reader to work.

Hi,

I would suggest you to change the drive letter in Disk management:

Method 1:

To assign or change the drive letter in disk management follow the steps below:

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.    In the left pane, click Disk Management.

3.    Right-click the drive that you want to change, and then click Change Drive Letter and Paths.

4.    Do one of the following:

·        To assign a drive letter if one has not already been assigned, clickAdd, 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, clickRemove, and then click Yes to confirm that you want to remove it.
