I assume you mean that you cannot format the new disk in Disk Utility>Ersae. Yes?
It won't let me delete anything off of it, or use it as the start up disc.
What are you trying to delete and from where? To what are you referring to as 'the start up disc'?
I sense that there is a possibility that there may be a problem with the new Seagate SSD. I think it is best that you set up the MBP the way it should have been from the very beginning.
Reinstall the original HDD back into the MBP and test it to see if it works properly.
(at least the MBP will be functioning again)
Install the SSD in the enclosure and connect it to the MBP.
Open Disk Utility and see if the SSD is recognized.
IF so, attempt to format the SSD via Disk Utility>Erase and if successful, copy the data to the SSD via Disk Utility>Restore.
If you get this far, test the SSD by booting the MBP with the OPTION key down. Select the SSD icon and if it boots the MBP, then do the physical swap.
If you encounter difficulties, you may have to contact Seagate technical support.
I know that this will require some additional work on your part, but I believe this is the best way to determine where the problems lie.
