I received a sincere attitude e-mail from eeshop. The e-mail is the next.

I opened a PC case and checked two DVD drive the original and dispatched equipment from "eeshop" again. I found that the both drives showed the same trouble that cannot find the drive from PC side. It was not happened before the time that I changed the device. So I researched the new trouble reason from that fact.
Then, I found the extended IDE cable connector of PC side was almost loose off. For that reason, the drive showed the same behavior.
I fixed(pressed) the cable connector and checked the both DVD drive again. The DVD drive dispatched from eeshop had no trouble. It works rightly.
I'm very sorry to treat "eeshop" with a skepticism. I thought eeshop is a good and reasonable shop. I might have a opportunity to buy something again.
Regarding the installation documents to replace the DVD drive that I referred was the next URL. This wrote in Japanese but has many pictures. I guess that it helps you to repair your PC.
