Installed 2nd Hard Drive, Windows could not complete the format?

I am Wondering if I did this correctly? I put my old laptops hard drive into my new laptop and want to use this for just more space,. When I put the drive in, my new laptops w/ Windows 7 , I formatted the second drive G: which was Windows vista, and It did get rid of everything in it, though, at the end of the formatting a window came up and said " Windows was unable to complete formatting" or whatever. I am able to move files and folders from my regular C: drive to the G drive and utilize the G: (2nd" drive). But when I go into Disk manager and try to format the G drive again, in order for it to "Fully" format it comes up and says " This drive has primary partition you sure you want to format? And also the G; drive shows as active? Why is that, if it is the 2nd drive? I don't understand. SO basically, I am wondering if someone can let me know whether or not I have properly done what I need in order to use this second hard drive as just extra space, and it is not holding any important things in it for my computer, like, can I take the drive out if I want, and then my laptop still boot up with just the regular drive that came in it, or have I done something wrong? Here is screen shot of my Disk manager C; drive is the main drive, which came with my laptop, and G: drive is the one I popped in and formatted, and it had said "windows was unable to complete format?

This is what disk manage looks like :


This is what disk manage looks like when I want to format 2nd drive. drive should be empty, why is it active? And why is is saying active partition if it is 2nd drive?
is this correct?

Try cleaning the HDD with CLEAN.
Disk - Clean and Clean All with Diskpart Command
than
Partition or Volume - Create New

Ok, I will look into that. Thanks. Though , I am not worried about losing anything on this 2nd drive, There is n o operating system on it, and appears to be clean/empty since I did the format, even though, windows said, It was unable to complete the formatting. There is 184/184 Gigs free on it and so I just dont see how windows says it was unable to format, when it seems to have rid the drive of everything, formatted it (NTFS) and made it a primary, active partition. I basically want to make sure I can take thid 2nd hard drive out if i want, and my computer still turn on like normal. I am able to read and write to the drive also... is this normal?

So I now have done all that you said, and this is what disk management looks like, Should I be all set now to just move any files or store any files onto this 2nd drive/Drive G: ?
sorry it is so small, the words, I am not sure how to make them bigger here, they look bigger on my real screen, but now here...
but just checking to seeif all i have done makes this all set?
