No new drive letter will appear for any new storage device (bar perhaps pre-formatted USB disks) until they are initialised and partitioned.
Run this command:
Choose to initialise the drive. Do NOT tick the box to create a dynamic drive.
Then you will need to right-click on the unpartitioned space on the drive and create a new NTFS partition & telling it which drive letter to use.
You will then be able to see the new drive letter along with all your other drives.
Thank you very much, smargh. Your solution worked like a charm! I was convinced that HP had it wrong when they claimed it was non-compatible.
Now, I would like to move the contents of my C: hard drive to the SSD, wipe the C: hard drive clean, and make my SSD boot drive. My BIOS does not have an option regarding boot order of multiple hard drives. How would I make my SSD the boot drive? Also, what is the best method for copying all of my C: drive files to the SSD? Should I simply "copy" or should I purchasing cloning software? Finally, how would I change drive letters such that the SSD now become the new C: drive?
