The instructions on the download page for DLG Diagnostics for DOS has a link on how to create a bootable USB stick (step 2). There is a utility called Rufus that makes a USB stick bootable, then you just copy the DOS version of DLG to the stick, boot off it, and then run the DLG command to start the program.
Windows will still install on the drive, even if a partition cross the “gap” between the SSD and HDD. The Black2 software is what splits the partition into the SSD and HDD. Since there is no OS on the drive I would make sure that your BIOS is set to AHCI and not a RAID mode. Sometimes this can cause problems with the software.
The tool to fix it should DLG Diagnostic and the Black2 software. This resets the drive and should hide the HDD and just show the 120 GB SSD. However, in some systems it may show as 1043.30 GB. This just means a single partition was created and the 1 TB drive is already unlocked. If you still have problems with the DLG then I would try installing Windows again, make sure you have the latest drivers, and then run the Black2 software to have it “fix” the partitions. Another thing that you can check in the BIOS is SecureBoot. Try turning that off to see if it helps since you are using Windows 8. SecureBoot prevents a program from modifying a partition/files during bootup, which the Black2 software may do to adjust the partitions.
