i have a Hitachi HDS721010KLA330 1 terabyte hard drive. my problem is it is only showing 931 GB, even after compressing. is there any way i can increase the space to full capacity? i use a lot of programs so the extra space will come in handy. i used Acronis Disk Director Suite 10 to increase the space after i formatted and reinstalled Windows, at that time it was only showing 128 GB until i used it to increase it to the current size. any help is appreciated.
