Please look for the correct model type - you are quoting an invalid model.  It will be something like PCG-TR1MP.

Confirm the model to make sure, but the TR-Series uses a 1.8 inch ATA/100 IDE HDD - originally 30GB.

This is a non-standard laptop drive - it is the same as found in iPods but needs the correct IDE interface.  Some TRs had a Toshiba HDD and others a Hitachi HDD.  These have different connectors.  You need to find which connector you have and buy the correct drive.

They are quite expensive: -

But when you have established the interface, try Google.
