Why does my computer not recognize this hard drive, when it is connected externally through USB?

I have a Compaq laptop n1020v. Recently, I have procured a ATA hard disk of 40 GB, which is recognized when inserted in the internal hard disk slot.

However, when the same disk is connected through USB cable, the disk is not recognized by the system and no message or otherwise is generated by the system. The disk is connected via USB cable through conversion from ATA to USB.

Moreover, the disk is recognized by other systems, be a PC or a laptop, maybe because they are of current version with latest software for external hardware.

Now my question is, how do I get the external HD recognized by the system through USB connected via ATA Adapter?
