I posted here a while ago about my 2TB portable WD Passport HDD (sorry about the title, I forgot which HDD I was complaining about...) that was giving me an error everytime I plugged it in. In the end I ended up reformatting it from FAT32 to HFS Journaled and performance seemed to improve; it loaded faster on my mac and seemed a bit smoother. Recently however I plugged it in and it made this really high-pitched buzzing sound, almost as though the disk was grinding against something, not the smooth buzz it normally makes. Disk utility was unable to unmount the drive and it would freeze finder. In the end I turned it upside down on the desk and the sound went away and to my surprise it loaded and I was able to use it as though nothing happened. Disk utility recognized and said everything was fine. Now that I know its a hardware issue, is there any way to fix it?
