Sorry dolmen ;-{

Your system can only handle SATA I (1.5 Gb/s) drives. See if this Toshiba drive offers a jumper to drop the I/O speed (check the spec sheet for it online).

Also, make sure your firmware is unto date, checkout this Apple TN on how to check it and update it EFI & SMC firmware updates for Intel-based Macs

Double check that you have the right SATA type… a SATA I or II not a SATA iii (what many new drives are).

If this answer is acceptable please remember to return and mark it.
