well WD replaced my old external hdd, and it worked fine for a few days, and the other morning it was making a really wierd loud noise, but it was still working fine. then the noise stopped and it also was working fine. i unplugged it (without safely remove hardware, but nothing was accessing the drive). now the pc wont reconise it, well, it knows somethings plugged in but wont show it. ive tried on different os's too. on the hdd it is making the normal sounds, except usually it makes a lot more noise when accessing the hdd (i think thats the problem), and usually the blue led light flashes to show hdd activity, but it barely does this. any ideas whats wrong? ive tried the freezer trick with no luck. dont rly want to replace yet another drive.
