My HDD is failing. I bought a new one and plug it in and everything is slow. Almost stopped. I checked my documentation and I know my MB supports SATA at 3.0gb but to be sure I also jumpered the drive to run at 1.5. Neither works. I have tried multiple SATA cables and multiple SATA ports on the MB. It's all the same. The system boots, it takes forever and a day to detect my drives but it finds them (even the new one) eventually. It boots XP but SSSLLLLLLOOOOOOWWWWWLY. I run the program that came iwth the drive (Seagae DiscWizard) but it wont' detect my new drive, same thing with Windows Disk Management. I think I'm going to just take it back and get a different brand but I wanted to see if anyone could think of a reason for all of this. I mean it's just a HDD, nothing complicated!
