The best recommendation I can offer is to check to see if it's available at www.samsungparts.com, or by calling them at 800-627-4368. I'm not sure if this is a user replaceable part, but they should be able to tell you either way.
Best of luck!
A while ago, i burned out my external drive. at first i thought i could probably just take out the actual hard drive and get an external casing for it. however, I later realized i burned out the Integrated Circuit Board attached to the drive. Right now I am planning on buying another of the exact same external drives to get the circuit board from the hard drive that comes with it so i can attach it to my burned out drive to get all my data. My question is, does anybody know where I could find a PCB or integrated circuit board for a samsung hard drive from a 1.5 tb story station external drive model # HD154UI. The PCB on the bottom of it has the code PHAZD7P5A62181. Thank you so much for your help. if there is no possible way to just order the board from samsung or somewhere else i'll just have to try buying a new story station.
