Hi laurieskye, I don't have any real answer to this mysterious happening, but to keep the thread live I'll air a few ideas. As I understand it, there are really 3 modes of restart. When you apply a soft restart (Start - Shutdown - Restart) the processor isn't initialised and so the BIOS doesn't start from the beginning. This is why old computers using overlay software to recognise larger hard drives than their BIOS is designed for won't recognise the full hard drive capacity using soft restart. When you do a full power down but leave the mains connected you still have 5V standby applied, so you can make use of the various optional wake-up modes (wake up on LAN, USb, modem, heyboard etc.) When you remove the power, then of course nothing is active and at switch on the computer is completely reset. I suspect that for some reason your slave drive is not being detected by BIOS without the complete reset.
