I ordered a Western Digital Passport Essentials USB hard drive for my Wii. I haven't received it yet, so I have no idea if its APM feature will cause me grief. Other hard drive manufacturers like Seagate and Maxtor have tools that allow you to disable the APM feature. I haven't found one for Western Digital yet. BTW, has anyone using a Western Digital Passport Essentials drive experienced problems with the spin-down on your Wii? However, I have found a command line utility that can help called hdparam. You can download the Windows version here: http://hdparm-win32.dyndns.org/hdparm/ WARNING! - This tool is not for noobs! You can seriously fuck up your hard drive. If your manufacturer provides a utility, use it instead! This is only to be used as a last resort. It's command line (non-gui) and the switches are case sensitive. Mix them up and you are dead! There are two possible switches that might work: "-S 0" or "-B 255" The "-S" switch sets the standby (spindown) timeout for the drive. A timeout of 0 should disable the feature. The "-b" switch sets the Advanced Power Management feature, if the drive supports it. A value of 255 should disable the feature. Note: there's also a special switch for Seagate drives: "-Z" Make sure to test if these settings survive a complete power down/restart. If not, you may need to add the "-K 1" switch to tell the drive to remember the settings. Remember, this won't work with a USB drive. You would need to remove the internal hard drive from the enclosure and connect it directly to your PC before you could even attempt using this tool. For those of you who are putting together your own external solution, this tool could be a lifesaver.
