Solved What is it that's booting up my external hard drives?

Have you try to run CHDSK System file checker on that particular disk?

There's related infos here

There are a couple of things that Windows does in the background:

• Search and install updates,
• Index documents for search,
• Prefetch frequently used files,
• Defragment the hard drive.

It's the "Indexing Service"/"Windows Search" services which are responsible for this process to run apparently. I'll try disabling them. "Windows Search" is a necessity at times right enough.
