Having trouble with 2nd HDD
OK, so I followed the guide here to swap out my optical drive for a 1TB 7200 RPM disk drive. It is not a hybrid drive. I left the 120 GB drive alone in the HDD bay.
After reassembly, the drive does not show up on my system. I took everything apart again, and started from scratch, even removing the drive from the housing and reinstalling. Still nothing.
I do notice a small lag in boot up (maybe a second or 2 slower than it used to be) and a weird graphic that shows up in the bottom of my screen right before I get to the login screen.
There is lots of info about choosing and installing a hard drive, but not a whole lot on troubleshooting, so any help would be appreciated.
