Hi, i'm French & i'm all new on the forum. I got a mac pro with 2 SATA hard drives which does cracking's noise. I know there is a way to active the AAM (automatic acoustic managment) to reduce this noise. I test to boot my mac pro with a bootable cdrom of the Hitachi Feature Tools software, but the keyboard isn't recognized by the DOS software. Someone can help me ? or know an other way to set the AAM on my hard drives ?
