|I am not sure what your 'slide in back up drive' is. If it is a SATA, USB, or similar hard drive, you should not need a driver. If it is a hot swap bay, you might require some type of driver, but I am not familiar with them. |
For any component that has a Vista driver, but does not have a Windows 7 driver available, you can try the Vista Driver, but you must use the 64bit version for your Windows 7 64bit (the 32bit driver will not work). Some but not all Vista drivers will work on Windows 7 since they are very similar 'under the hood'. This is because Windows 7 is what Vista should have been if they did not rush it out before it was really ready.
Look into the BIOS set up and make sure that the drive is shown there. Then look in Disk Manager within Windows 7 and let us know what it says there for the drive (if is shows up there).
You have to be a little bit crazy to keep you from going insane.
