[*] Where are the Western Digital "Green" drives? Weren't those recommended before?
Western Digital "Green" drives are the quietest 1TB drives available, but all
of those drives are now manufactured with an Intellipark feature that cause both the TivoHD and Series3 to hang after a software reboot. These hangs occur after restarts initiated through the TiVo menus and restarts that follow software updates. These drives only boot correctly in a TivoHD/Series3 after the power plug is pulled. These updated drives will not boot at all in the Series2.
This issue affects all recently manufactured Western Digital EADS, EARS, and EAVS drives. It also affects EVVS drives manufactured after
September 18 and EVDS drives manufactured since November. Drives built prior to these dates work perfectly fine; they do not
exhibit the issue. The manufacture date is printed on the top of every drive.
For newly built Western Digital "Green" drives that exhibit this issue, TCF member drey
discovered a method to disable the Intellipark feature on these drives, thereby making them fully compatible with the TiVo (i.e. no more "soft reboot" issue). Instructions below:
The procedure only works for drives connected directly to a computer with SATA or eSATA. It does not work for drives connected with a USB -> SATA adapter.
Download this bootable CD with wdidle3.exe. Burn the ISO file to any CD-R disk using Windows 7, OS X, or a free program like ImgBurn.
Connect the affected WD drive to any available SATA connector on your motherboard.
If you have a newer PC, you may need to enter your PC bios and temporarily switch your SATA controller to EIDE mode from AHCI/RAID. This change is needed before a bootable DOS CD can detect the drive on some newer PCs.
Boot from the above CD - hit "Enter" within 15 seconds to boot to DOS and then run "wdidle3 /S300".
A message should indicate "Idle3 Timer is enabled and set to 300 seconds (5 minutes)." That means you were successful.
That's it. You should no longer have the "soft-reboot" problem.
This procedure has no affect on the TiVo software, settings, or recordings on the drive, so it can be performed before or after a backup and restore.
If you think you may have installed one of these newer Western Digital "Green" drives in your TiVo, but are not sure, there is a simple test. Restart your TiVo through the Messages & Settings -> Restart or Reset TiVo menu. If your TiVo boots properly (give it ten minutes), then you have an older drive that does not exhibit the issue. If the TiVo refuses to boot until you pull the power plug, then the procedure described above should eliminate that problem. It has no known ill effects and it will not affect your TiVo software or recordings.
