How does Microsoft's UVCView utility see the external drive?

Does the drive spin up? If not, is it making a sound as if it is *trying* to spin up? Any vibration?

Did you drop the drive? Did you overvolt it?

Assuming your AC adapter is OK, then you may need to remove the drive from the enclosure and attach it directly to your computer's motherboard. That said, some USB drives incorporate the USB-SATA bridge IC on the hard drive's own PCB, in which case you will be in trouble.

So you have any suggestions?

The Vendor ID (0x13FD) belongs to Initio Corp.

The Product ID (0x1618) is that of a USB bridge IC, ie INIC-xxxx.

This idicates that your computer is detecting the USB-SATA/PATA bridge IC inside the external enclosure, but not the drive behind the bridge. I believe that if everything were working correctly, then the external device would identify itself with Samsung's Product ID and Vendor ID.

Before removing the drive from its enclosure, I would confirm whether the power adapter is OK. Otherwise, if the drive is powered from the USB port, I would try a USB Y-cable. Some USB ports cannot provide sufficient power to spin up the drive, so a Y-cable is needed to pick up power from two ports.
