today i bought a brand new wd blue 1 tb hdd, and right after i got it i dropped it on hard floor, from about 4 feet. it was still in the anti-static package and wrapped in a pretty thin foil and bubble wrap. my other parts for my new pc didn't arrive so i checked with my old pc and the hard is beeing recongnized in bios. does it mean it is working? or even though it is recongnized it may be broken and unusable?
