Have a Dimension 8300 with only one hard drive, the original\nfactory installed ST 120GB ATA/100 drive. I need to add a\n2nd hard drive for additional storage, and can choose from\nanother Seagate ATA/100, which is easy to hook up.\n\nBut can I add a Seagate SATA drive, as the 2nd drive? I've\nspent the last 2 hours reading Dell Talk messages, and some\nindicate you cannot (both drives must be the same) while\nothers report they have successfully, and easily installed a\nSATA drive as a 2nd drive.\n\nIf this can be done, just have a few questions.\n\n1. Was planning to connect the SATA drive to the SATA 0\nconnector on the MOBO, connect power, etc. (drive comes with\nall cables). On boot-up, in SETUP, set Primary SATA to\n(AUTO). QUESTION: Do you set the Secondary SATA to AUTO as\nwell?\n\n2. What about jumpers? Currently, the ST ATA/100 factory\ndrive is set to CABLE SELECT?. Do I also set the SATA drive\nto CABLE SELECT? Or do I need to do a MASTER/SLAVE, since I\nneed to keep the original factory ATA/100 as the primary\nboot drive.\n\n3. Once the above is done, I understand I go to Disk\nManagement, and format and partition the drive (unless the\nSATA drive has it's own software, haven't opened the box yet).\n\nThanks for any help/advice.\nGary.
