Hi, I have a new harddisk. It is Hitachi 160G SATA. The bios detected the new harddisk, but after waiting about 20 seconds when booting , I got this message: Harddisk Error (XXXX) In the CMOS setting screen, the harddisk has been detected, but its size is 0,and other parameters are blank. I also heard strange sounds ( not too sharp) after powerd on my machine. My motherboard and CPU are both new. I have tried set the IDE mode to non-RAID and AHCI, and have changed diffrent sata ports. The sata cable was come from my motherboard, so it could't be a problem. Is the harddisk bad ? Thank you.
