I can guarantee you, that it will need to be disabled, or set to 300 seconds (the max setting). If the drive firmware rejects the WDIDLE3.EXE /D command, you use the /S300 to set it for the max. The status can be verified with /R, which reports the current status, and can be used to verify the drive accepted the parameter.
The issue with not disabling it, is a warm-reboot, that does not involve pulling the power cord, will let the default EZRX setting park the heads during a period of drive inactivity while the TiVo is only accessing the PROM. The unit will hang on the startup screen.
All of the non-AV-GP Green series drives are still shipped with the idle mode 3 timer set to just a few seconds. The Roamio product line boots differently, and is not affected by it.
The variable that many confuse about the "if needed" part, when excluding the Roamio, is that WD used to ship the AV-GP EURS/EURX drives with the same few-seconds timeout set. They stopped doing so years ago, and have been shipping with it set to "Disabled", ever since. There was a period of time where the mfg date of the drive you got could have been on one side of the change, or the other. You didn't get that model, so using a PC, and a direct SATA connection to the mainboard, along with a special boot disk/disc, will be necessary.
Talk to unitron, on getting a copy of what he recently downloaded to use for his own upgrade.
