ok heres the problem: my main hard drive is 80 gb SATA,and my new drive is the western digital 250 gb SATA drive. so i bought my SATA cable, installed the backup 250 GB drive into slot 1, connected the power and then connected my SATA cable to slot 1. i boot up the computer like normal, but recieve an odd problem: My drive 4 (port PATA 1 PRI IDE slave) and drive 5 (the master, im not 100% sure if 4 is the master or if 5 is) are not detected. i went into the bios, both are turned on and recognized. i disregarded this and turned on my drive 1 to try my new hard drive. when i booted up not only is the new drive not recognized, neither the DVD or CD is either. the only thing showing up is my c drive and floppy drive. i turned the drive 1 off(controllerarallel ATA for drive 1 and 0), disconnected the SATA cable, and tried rebooting again, yet i get the same error message. so before i had tried installing this drive i had no problems, now even after disconnecting the drive my DVD and CD drive wont show up. The SATA operation is currently set to Raid auto detect/AHCI. the other options are as follows: Raid auto detect/ATA, Raid ON, and Combination. in similar problems i found here people said to change to combination, which is SATA/PATA. does anyone know what to do? im left here not being able to use my new hard drive, and ontop of that my cd and dvd drives!
