Hello all, I've replaced the dvd on my macbook4.1 with a bay and added my old disk there (WD Scorpio Black) and an SSD on the HD compartment. The disk was old, but I really was surprised to see that it died in a week! I bought a used ssd on eBay and replaced it. And guess what? After a week it died too! It might be a coincidence, or there might be something wrong! I'd really need your help and advice on this! Yes trim is enabled and the laptop is always on a stand so no moving or hits. Thank you all in advance!
