Is it an external drive via USB? A network drive, with embedded 
Linux/SAMBA? Or has a drive been swapped out of a Server? If USB, check 
the BIOS USB settings. If a network drive, there's a management utility 
that came with it. Run that and check the inactivity settings. If a new 
drive in a box, check the BIOS settings for inactivity.

Unless Windows puts drives to sleep as well. Maybe check system settings 
or power settings.
