Went through the same as everyone else who recently purchased a Acer Predator Helios 300 laptop. The laptop and a 2nd - 2TB SSD drive bundle was offered on Amazon, so I purchased thinking it was a great deal. After reading the Acer website literature on this laptop, it is advertised as shipping with a 2nd HDD hard drive caddy and SATA cable, pre-installed. When I received the laptop, of course there was no caddy or sata cable. So I went through the headache and lost time of contacting Acer and I was told they would ship it. 2 weeks later, I finally received the kit via Fed-Ex. Excitetedly I open it up and proceed to install my 2nd -2 TB SSD drive. Here's where you can queue up the Price-Is-Right - "I just lost playing Plinko" sound bite (yeah...the one played repeatedly on Archer). The 2nd HDD caddy and the cage itself are a piece of cake to install...no problem. The 2nd HDD sata cable....that's a completely different story. You have to remove the 15 screws from the laptop, use flat pieces of plastic ( I used two plastic orange peelers) and you got pry and pop open the entire laptop and remove the entire keyboard to locate the connector for the 2nd HDD cable. They have confusing directions with very poor screen shots on Acer's website on how to do this. I followed the instructions and connected the cable to the connector on the motherboard and in the process caused some minor damage to the case itself.....I then put the entire laptop back together. I boot into Windows and nothing....the drive is not detected. I reboot Windows and hold down the shift key on shutdown and keep holding it until it boots back up. It then goes into a advanced startup menu. I go into the BIOS itself and I see that the 2nd HDD sata slot is enabled but no drive is detected. At this point I'm **bleep** and I contact Acer again. They basically told me that it was my fault because I didn't follow the instructions correctly. I then threaten to send the laptop back to Amazon and demand a refund. The tech then scheduled a phone call with a "2nd Level Technician" for today. I still have yet to receive any phone calls (I have the case number and the transcript from the online technical chat). I'm seeing enough complaints on the boards here to see this is obviously a wide-spread problem. Shame on you Acer! This is deceptive advertising and horrible customer service.
