Review on Replacement KEM 450AAA CECH 2001A CECH 2001B CECH 2101A by Chris Long

So you know because I didn't notice until I put it in and it didn't work. This is not a simple hard drive replacement. You have to disassemble both hard drives and swap the circuit boards. Luckily I built my own computers in my day so it wasn't too bad. Also, the two screws were sealed with some insanely hard alien tech stuff, lol. I had to burn/melt it to soften it. Then the screws fell out when I reassembled them because they were too small. Also, the screw on the back broke and I had to glue it back on. BUT, if you have some skills, this is a very good deal. However, they could be a little clearer on the details. Other than that, my PS3 is now working like a charm.
