I have a macbook pro 15" 2014 and one day I was streaming to my chromecast watching a movie and when it finished I grabbed the laptop to search something up to realize it had froze during the movie. I held the power button down until it shut down and started it back up again. black screen with folder question mark. researched what can be done, tried: "command+r" disk utility couldn't discover the drive and trying to reinstall osx no drive popped up "D" error VDH002 possible problem with hard drive "cmd+option+p+r" nothing took the bottom off and removed and reinserted the ssd. still nothing. finally grabbed another macbook took it apart and stuck the ssd in and nothing happen, but the drive from that laptop booted right up on my main. ordered a new 512gb for $340 off ebay hopefully I dont have any issues with that order but my question is why the hell did it fail???? some research suggested heat as the culprit so my other question is whether anyone has tried appling a heatsink to the ssd. I've found these copper shim "heatsinks" im thinking of applying with thermal paste or might order these interesting micro porous ceramic heatsinks I found off a website which are supposed to be 30% more efficient than metal ones. they're made for raspberry pi chips but thought I would give it a try can anything be done with the old m.2 ssuax ssd? can I sell it to someone for some value? thoughts about the heatsink on the ssd?
