Alright, so long story short my home built desktop has 3 hard drives.
One of which is a far newer Western Digital Caviar Black 750gb drive.
The next oldest drive is approximately 4 years old 250GB seagate hard drive that was I originally got as a replacement drive for an older computer.
The third, and oldest drive at nearly 6 years old, was the drive that was the one replaced by the drive mentioned above. I was able to repair the drive and has worked quite well for quite a while. It is 250GB Western Digital drive, some OEM model put in an old HP circa 2005.
Since my desktop was the product of a long series of drawn out upgrades (unemployed high school students tend to have small computer budgets
) and at least 3 seperate installations of OS's (one vista, one windows 7 RC and one full windows 7 pro 64-bit) the later two were done on the Caviar Black.
However, the Master Boot Record, it appears, is on the oldest of the drives.
It also appears that the disk is failing (or at least that is my guess).
This is because occasionally when I start my computer it will tell me I have No OS installed. The instances in which this happened has increased over the past week or so.
Other times it will boot properly to the screen where I can choose which OS I would like to boo, even though Win 7 pro 64-bit is the only one still actually installed.
My question is how can I move the MBR from that older failing drive to my primary drive, the Caviar Black?
Also what are other tests and diagnostics I should/could run to see if the drive is failing and get a better idea of how soon I need to get a new drive.
P.S. System specs below are up to date
