16. Are there any drives to avoid?
All recently manufactured Western Digital "Green" drives are no longer fully compatible out-of-the-box. They exhibit a "soft reboot" problem, where the TiVo is stuck on "Welcome...Powering Up" screen after every software reboot, including restarts initiated through the TiVo menus and restarts that follows software updates. Refer to FAQ #14 for more information.
Stick to the drives listed in the table above and you will be fine.
i am not sure.. the drive that i have listed http://www.wdc.com/en/library/sata/2879-001146.pdf
is that listed as a "green" drive? I don't see info on that.
and i do appreciate your help on this.
This is due to a feature called "Intellipark", which parks the heads when the drive is idle for a period, the default being eight seconds. While a TiVo Hard Drive is not normally ever idle, it does do so during a soft boot. AFAIK, this feature is only on the WD Caviar Green drives. This is a specific product line and is not just a case of a generic designation of them being "green", i.e. "eco-friendly". Your drive is just a regular Caviar and should have no problem. If you decide to go with a new, larger drive, the feature can be disabled. I installed a WD 1TB Caviar Green drive in my TiVo HD last year and it is running fine.
From what I have read. there is a potential problem restoring to a drive of the same size. Even though both are 160GB, the actual sizes can be slightly different, particularly if they are different manufacturers. If the "new" drive is larger or the same size, you should be OK. If not, it may not work. Once you determine the brand and model of drive currently in the TiVo, you should probably go to the "Expansion" thread and ask about it there.
You should also visually inspect the TiVo power supply to see if it exhibits any sign of "capacitor disease". The most notable symptom is bulging ends.
I would also suggest running the manufacturers diagnostics on both drives, obviously only the non-destructive ones on the "old" drive.
How are you planning to connect the drives to your computer? If you are planning to use a direct SATA connection as opposed to a docking bay, do you have a Gigabyte MB?
