Folks, I started having constant reboot problems with my TivoHD last week and ran some of the KS test that is suggested in this thread. Although I did not find any failures with my DVR expander, removing it resolved the rebooting issue. Now I am on the lookout for a 1GB DVR Expander and I cannot find it anywhere in stock, so I guess WD stopped manufacturing it. The next step is to replace the internal drive with something bigger as 22hrs of HD recording simply won't do in my case. So I have been reading this wonderful thread and I have decided to get the WD10EVDS since they are extremely quiet. I do not have access to a desktop and an SATA port on the motherboard to disable the IntelliPark feature, hence I am deciding to buy a Hard Drive Kit from ebay. Now if I follow the procedure detailed in the FAQ on the first page, I make a backup of my original drive and then restore it to my new drive and I am golden .. ie. no need to re-do my Season Passes, CableCard Info etc .. However if I install the ebay kit, I don't mind re-doing the season passes, however I am afraid of losing the CableCard settings. I know I have to re-do Guided Setup and hopefully I can get access to all the channels and in case I don't I might have to call the cable company and I really shudder at the thought of dealing with the service representative at the cable company when dealing with cable cards. Just wondering whether I should find a friend that has a desktop and install this myself or should go for the Ebay kit. If anyone has gotten an Ebay kit and installed it, can you please let me know of your experience with the install. Thanks!
