So my hard drive is messed up. SMART Status says "Failure Imminent," about 500 or so reallocated sectors. I ran Hiren's Boot CD 15.1, did WD Diagnostic, wouldn't even write zeroes, gave me an error, so I guess it's time to replace the drive. I would like to buy a Seagate drive if possible, instead of Western Digital. And I will probably buy from Tigerdirect.ca What kind of drive do I need? I'm kind of confused with the terms, SATA, SDD, etc. The drive in the laptop now is Model # ATA WDC WD5000BEVT-22A0RT0 ATA Connection 5400 RPM 500 GB Thanks!
