What the hell!!!

Infuriating! Just bought a new Western Digital 250GB hardrive a month ago and it already shows S.M.A.R.T errors, warning me to backup my data and replace it. The reason I bought it in the first place, was to replace a previous WD 200 GB hardrive which failed similarly. Except this one didn't hold a month! Either Western Digital is no longer a reliable company it used to be, or K.S.P is selling junk! Another slight possibility is that my computer is somehow causing it. But I really doubt it as I have another 4 hardrives connected to it, some as old as 5 years! Now how the hell am I going to backup 238GB of data?! Buy another one? The DVDs and CDs alone are gonna cost me a fortune.
