    Has anyone noticed the new Macs goes to sleep even *with* activity happening to hard drive?

    For example. when wiping the hard drive (zerodisk from Terminal when booted from flash), and the Mac goes to sleep, the hard drive temporarly stops as well ?..

    This is anoying, to the least, especially when it should take about an hour, then you come back and wake it up, only to find its not progressed any further within another hour.

    This happends on both A/C and battery. I can see why it would happen on battery but not on A/C pluggin in..

    Don't use "zerodisk" then? Just use Disk Utility.

    It's also not clear what you're booting into... OS X on a flash drive? (Again not necessary as you can use disk utility from the recovery partition too)
