I’m still having this problem on OS X. I just Bootcamp’ed my laptop and installed Windows 8 on it. So far, I’ve been unable to replicate the problem there. However, I also don’t even have the option to disable HIPM or anything like it under the Hard Disk power settings. I’m guessing that’s due to the BIOS compatibility layer that Macs use, but if anyone knows how to turn on HIPM anyways then I can see if that recreates the problem.
I’m not sure if OS X supports HIPM / DIPM at all - there doesn’t seem to be a definitive answer online.
