If you have two harddrives inside your case that are now being shown as only one, then the only way that would possible is if you have a RAID configuration. I have two harddrives that are setup in RAID to mirror each other and that makes it so that when I look in the My Computer folder, I only see one drive even though there really are two.
The name of my RAID card shows on the first screen when I start the computer and the harddrive shows somewhere, I think it is on the next screen, as 1X2 Mirrored.
There are two ways that I know of to know for sure which you have, one is to open the case and check how many harddrives are installed. The other way is to go into BIOS and check the harddrives in there. If you have two harddrives, they should each show up in there.
If you did the reformat and install yourself, and did not setup any RAID configuration, then I would think you only have one harddrive and it was partioned into two partitions before you formatted it. If that is the case, then when you opened the My Computer folder, it would have shown as two seperate drives. When you did the format, you only made one partion so now it shows up as only one drive.
If you can open the case, take a peak inside to be sure.
Just thought of another way you might be able to check to see how many drives you have. Right click on the disk in the My Computer folder and select properties, then click the hardware tab. When it shows all the disks, see if your harddrive shows as 1+0 span, or something like that, like mine does. If it does, then you are probably running a RAID configuration and have two harddrives. If it does not, you probably just have one harddrive installed.
