For a Seagate drive, go to the Seagate website and download the software for your specific drive model. You can also try troubleshooting by checking that your drive is connected directly and correctly to the computer's USB or Firewire port. Ensure that the Windows power settings are properly configured.

Use a plugin
A plugin can be used to wake up a sleeping hard drive. A user on the jpsoft.com forum suggests that a command such as "WAKEUP <drive>" could be used to wake up a sleeping hard drive. The command would return immediately after starting a thread that would attempt to access a specified drive.
Another user on the same forum suggests using a plugin THREAD command: "THREAD *DEL /Q %@UNIQUE [d:".
It is important to note that plugins and commands may not always be a reliable solution for waking up a sleeping hard drive. In some cases, they may not work as expected or may cause other issues.
For example, a user on the Super User forum mentions that they tried using RevoSleep, a software designed to put HDDs to sleep and keep them offline, but it failed during boot time and threw out random errors.
Therefore, while plugins and commands can be a potential solution, it is essential to thoroughly test and consider the potential drawbacks before implementing them.

Use a freeware
If you're looking for a freeware solution to wake up your sleeping hard drive, there are several options available. Here are some detailed instructions for using freeware to address this issue:
- NoSleepHD (nosleephd.codeplex.com): This freeware helps keep your external hard drive from going into auto-sleep mode. It works by writing an empty text file to your hard drive every few minutes, preventing it from automatically sleeping. Simply download and install NoSleepHD, and it will run in the background to keep your hard drive awake.
- KeepAliveHD (keepalivehd.codeplex.com): This freeware is similar to NoSleepHD but works on both your primary and secondary drives. It writes empty text files to your drives to prevent them from going into automatic standby mode. Again, download and install KeepAliveHD, and it will run in the background, ensuring your drives stay active.
- Mouse Jiggler: This freeware prevents your Windows computer from going to sleep, which in turn keeps your hard drive active. It simulates mouse movement, so your system thinks you are still actively using it, preventing the hard drive from sleeping. Mouse Jiggler can be useful if you want to keep your entire system awake, not just the hard drive.
- Sleep Preventer: Sleep Preventer is another freeware option that prevents your computer from entering Sleep, Hibernate, or Standby mode. It ensures that your hard drive remains active by keeping your system awake. This can be useful if you want to maintain system accessibility at all times, but keep in mind that it may impact power-saving settings.
Remember that while these freeware options can help prevent your hard drive from sleeping, they may not directly "wake up" a drive that is already asleep. For that, you might need to explore other solutions or consider adjusting your power settings to prevent the drive from sleeping in the first place.
