People need help or a good HDD for replacement?

The thing is the HDD which is around 8-10 years worth to change it?

WD Caviar Black 640-Gb


Diagnostics was carried out running from a USB system!

Confuse indicators HDDScan S. M. A. R. T Paragraph 199 UltraDMA CRC Errors

Although other programs show a clean S. M. A. R. T

And yet the program HDDRegenerator Atributte 3: Spin-Up Time is also not clear what a cross!???

And we understood the testimony of Victoria is acceptable???
