Mac tool to turn off APM on external hard drives?

[bigwig]

The Automatic Power Management feature of some hard drives destroy drive life by unloading the heads and powering down with extremely high frequency. Is there a Mac tool to disable this misfeature?

There is nothing bad about the APM features. I've known of hard drives that have spun non-stop for a few months and die and drives that spinup every 15 minutes to write a few megabytes of data and last for years at a time. It is common misconception that such activities cause harm to a hard drive's health, when the hard drive is actually made to do such things.
