The drive is of course fully supported - that's why its (other) details (temperature, health, ATA, SMART and so) are displayed in the software.
Hard Disk Sentinel uses a database to provide the information you listed for each drives. This database is constantly increasing (now it has information about 3746 hard disk models, you can check in the About box, under the version number). The HD103SJ model is not yet added to this database, that's why these details are now missing. I'm adding it to both to the software and the online version of the database, which is available at the website under Support -> Knowledge Base -> Storage information
so these details will be available soon.
