Hi,
Notebook 2000-369WM as Windows 7 and G60-231WM as Windows vista. You want to connect the HDD of G60-231WM to Notebook 2000-369WM. I checked the specification of Notebook 2000-369WM where it does not have an option to connect 2 HDD. Since the G60-231WM is running Windows Vista and the drivers loaded in that HDD would not support the configuration of Notebook 2000-369WM. So what you can do is copy the data from G60-231WM to external HDD and then transfer to Notebook 2000-369WM.
Then you work on the Notebook 2000-369WM without any issues.
