Nope. Cannot remove or add anything. The socket on the mobo is designed to receive fins that get lowered into it as the installer holds on to a little ribbon-like handle. SATA has one large blade that slides horizontally into a socket with one big slot (with the exception of a plastic orientation block ). Going further on this 2009 laptop simply ain't worth any rigging that may or may not work. It's pig-slow, but it does run. I'll hang on to the PNY SSD for some future project. Amazon shouldn't have to eat it.
The hard drive you removed should have the adapter that matches that motherboard socket. That is not an IDE nor a SATA connection, that is an add-on adapter that fits over those connections on the hard drive. You need to take the original hard drive and look at it, it either has that adapter over the regular pins or it was a custom made drive with the connections on it.
Grab a hold of the black plastic around the original drive connector with some pliers and gently wiggle the connection back from the drive, I'm going to guess that it will come off revealing the standard hard drive connections. I have worked on many laptops that have those connectors and that is exactly how they work, they just slide over the standard hard drive pins. If that does not come off, then Toshiba had the drive vendor make them a custom board for the hard drive and you can't do anything there.
