I have 5504 RTV and was working fine. I wanted to upgrade the HDD from 40G to 160G. I read online to see how to do it and then finally came up with RTV Patch tool. To do this, I opened my unit and took the original HDD and put it in computer as suggested. However, my computer didn't have more than one HDD. So I thoght to connect new HDD (160G) and replay TV HDD in secondary IDE as slave and master mode as suggested in the forum. Since I didn't have any operating system installed in an another HDD, I booted my computer using WINXP CD. By doing that I think I destroyed the operating system of my original HDD since boot CD probably wrote something on my original HDD. Being skeptical, I put the original HDD back to my REplay TV unit and nothing worked.
Now What can I do? How can I get my original HDD back so that I can reimage it to new 160G drive?
