Dimension 8400, Maxtor Sabre SATA HD which replaced an original OEM HD that failed.  About two weeks ago got Blue Screen had to manually shut down.  Worked fine for two weeks and now clicks and repeated beeping as it starts up.  Says SATA 0 not recognized.

 

Have been on DELL Hardware chat for several hours.  I'm now at the point where they are asking me to disconnect all drives and cards, and then try to reboot.

 

Does anyone know where they are headed?  They identified the HD problem pretty fast last time so this seems like they are looking for something else.. 

 

 By the way if I did lose two hard drives in 6 months ...is my power supply bad?

 

 

Any help?
