With Western Digital releasing the first internal 3TB drive, and Seagate with a drive in the works (though public release still a ways away), consumers interested in these ‘megadrives’ are being forced to pony up the extra cash to purchase a third party solution to overcome the 2.19TB drive limitation of the modern system.
Not for ASUS motherboard owners however; the company has released its very own solution specifically for Asus motherboards that allows users to use their full 2.2TB+ hard drives, and it is absolutely free!

Disk Unlocker- a brand new exclusive (patent pending) technology from ASUS. This is the first software solution to overcome current operating system limitations that prevent a hard disk drive from utilizing more than 2048GB (also known as 2.2TB). With just a few clicks, Disk Unlocker taps into hidden storage space beyond the nominal 2048GB range, helping you use large hard drives to their maximum potential.
The best thing about Disk Unlocker is that it works with every ASUS motherboard, hassle free. All you have to do is to download it from http://event.asus.com/mb/2010/Disk_Unlocker/ Once installed, it will immediately enable access to hidden space. Disk Unlocker comes with a user-friendly interface and is incredible easy to use.
The software is available for both Windows XP and Windows Vista/7 and works with 35 different Asus motherboard chipsets (see product page for details).
Enjoy maximum storage, effortlessly. Add data, media and all kinds of content, worry-free. It’s a clever and simple way to maximize not only your storage capacity, but also the value you get from your hard drive. With Disk Unlocker, there’s simply no reason to leave that storage space out of reach!
