This is for anyone who may be reading this and wondering about the Platinum PWD5000YS hard drive. In all, those are bogus branded hard drives. I myself am the unfortunate owner of one of these hard drives. It has recently stopped working on me, and I couldn't find any useful information in Google Regarding the PWD5000YS model number. When I investigated the PCB, my so called Platinum brand hard drive traces to be a Western Digital. Go figures...
Since my hard drive had a bogus label sticker at the front with unoriginal information, it is very difficult for me to determine the firmware and the model number of this hard drive. My guess would be that the PWD5000YS is actually a WD5000YS (which is an actual Western Digital model hard drive that has the same specs as mine, 500GB etc...). But I could be wrong. Hopefully the guys who put that label sticker were nice enough to do that.
What makes this an even more complicated situation is that I'm not even sure if Western Digital would even bother trying to help me out with this.
