Hey there, Mister Darius!
I'm sorry to hear about your issues with your current WD Caviar Blue.
I'd strongly recommend you to use WD's Data LifeGuard Diagnostics instead of CHKDSK to check up on the health and SMART status of the drive. Here's a link to the WD software: http://products.wdc.com/support/kb.ashx?id=9E4z3o
Make sure you run the QUICK as well as the EXTENDED tests from the utility.
I'd also suggest you to try using a different SATA cable to plug the HDD with and also try using a diffe7rent SATA port on the motherboard.
Keep me posted with the troubleshooting!
