Hello kd4wat,
Thank you for your reply!
The error "Parameter is Incorrect" is an indication that the drive is in use. I have added some steps below that I hope will correct your issue. Please let me know status.
To change the drive letter or paths in Windows Vista, just follow these simple steps:
- Right click on Computer and select Manage to open and access Computer
Management
Console.
- Navigate to and expand the Storage section, and click on Disk Management to access Disk Management Console.
- Disk Management Console display the details of all available volumes and disk drives in the
computer
configuration
in the right pane.
- Right click on the volume or disk drive that you want to change the drive letter, and select “Change Drive Letter and Paths).
- Then click on “Change” button.
- Use the drop down list to select the new and your desired drive letter to assign to the disk volume.
- Click OK.
- Click Yes to confirm.
Any letter between C and Z can be assigned to a hard disk drive, CD drive, DVD drive, portable external hard disk drive, or USB flash memory key drive, while floppy disk drives use up letters A and B. Beside, the drive letter for the system volume or boot
partition cannot be modified or changed. And if you install some applications or programs in the drive that you have just changed the drive letter, they may not functioning properly after the change due to the possibilities that the programs will also refer
to the specific drive letter or original path used when installation as environmental variables.
