LOTS of people are having this very problem. Apparently the manufacturer wanted to help us save energy and did so at the cost of functionality. So far the only solutions I've found (mind you none of them from Seagate directly - they're closed), is to use a PC to manage the time settings. I have installed two versions of their software so far, one strictly diagnostic and one that was supposedly a control center. In reality neither of them allowed me to correct the sleep time (I prefer NONE) and neither of them even had the option to. I checked again just to be sure.
Seagate used to be my first choice when it came to drive technologies. I will now be avoiding them. In their rush to cash in on the Mac craze they forgot the basics and flubbed up pretty badly.
There are some suggestions of using the command line "pm" utility to set it but I don't see a lot of success reported.
Note to Seagate:
In the future, please allow us, your customer, the people who give you money, to decide what our drives do. Do not create proprietary software required to interact with your products, it only turns us off. I do NOT want to install your software to use something that should be based on existing industry standards.
Thanks.
