I just installed a 3rd gen Seagate ssd 1tb in my 2008 Mac mini a1176. It’s not working. I first mounted the new drive with a USB enclosure and formatted it then used carbon copy to clone my old hd. After installing the ssd, the mini powers on lights, HD spinning but no ideo and no USB power for the keyboard! So I can’t even boot with the lion disk in the optical! Took it apart put the old hd back and it works fine. Going to reformat the drive but not clone and see what happens.

@Romeu Peitinho - Sadly, you can’t use a SanDisk Ultra II SSD in your system as it’s a SATA III (6.0 Gb/s) drive and your system is only designed to support older SATA II (3.0 Gb/s) drives. You’ll need to find a fixed SATA II drive or one that auto senses the systems SATA port like this drive: Samsung 850 EVO SSD. Note the Interface line.

hi Were you able to hear a Chime sound after the installation of your new hard disk ? Between if you have installed a SSD then you cant hear the HD spinning as in SSD there is nothing that spins, it just has chips in that.
