Windows 7 - Win7 Reinstall > Cannot read 2nd HDD

Hey there, I recently reinstalled windows 7 HP x64. My primary hard drive (where windows sits) crashed and burned, and I received a new one under warranty. So, I partitioned it and reinstalled windows. Everything is set up exactly as it was before. Only, windows is now not recognizing that the 2nd drive is already formatted with data on it (this is where my music and documents are located - plus some extra things I backed up prior to the drive dying completely. (It was a SMART event, I had some warning.)

It shows the make/model of the drive, but has no size information or file systems listed. The most recent drivers are installed already. Windows has been completely updated since the reinstall. There is no damage to the drive - reinstall didn't touch it.

Everything is still there, but windows says that it needs to be formatted before it can be used - the filesystem is unrecognized. (It's NTFS, one partition.) So how do I get Windows to realize that the drive has been formatted already and works just fine?

Just try this. Switch off your PC, unplug it from the mains, and then disconnect the data and power cables to the second drive. Reboot your PC with only the primary drive and then shut down your PC. Disconnect it from the mains again, reconnect the data and power cables to the second drive and then boot your PC. Check whether your second drive is now recognised.

If not, please post the screenshot of the disk management and let us know how the second drive looks in it.
