Need Help Locating TVS Diode on Seagate HDD (PHOTO INCLUDED)

[tomneily]

Please help me confirm the location of the TVS diode on my ST340015ACE. It contains valuable data that I need to back up. Any help would be greatly appreciated. Thank You, in advance! I have included a photo.

Hi I will help you - to help yourself.
1. the picture is not good enough quality to read the markings on any component.
2. The TVS diode is normally one of the largest black components that is not an IC. They are normally near the IDE or SATA connector.
what you need to do is start plugging in the numbers on the components into Google that are candidates based on what I just said.

or, google images:

Thank You very much for your help! Sorry about the duplicate posts, I am new to the forum and I wasn't sure if this post would be rejected for having a link. So, I saved the image as a. Jpg and it posted without requiring approval. Btw, the markings are 611 15A. On the larger diode and AE 0611 on the smaller. [*]

Especially to you, islamm3rouf! I knew it was one of the two and I've been repeatedly trying to search the part numbers, but to no avail.
