Greetings! I have an MDD dual 1.25 gHz running Leopard (10.5.8). I am using an ATTO UL3D SCSI card to run a 2 drive internal SCSI RAID. Hoping to get better performance, I upgraded the ATTO driver to the most recent one provided by ATTO for PPC and Leopard (or below), which is their version 3.21. Everything still works, but the new driver did not enhance performance (I'm getting about 125 MB/sec. on uncached 4K block reads). Not only that, but the new driver will not allow the SCSI drives to spin down and sleep.
My boot drive is an OWC 115 GB SSD. The old driver (version 2.04f1) works just fine with this setup, and WILL allow the drives to sleep. I have verified this by booting from another drive that has Leopard with the old driver. So, the question, how do I get the new driver out of the system and re-install the "old" driver. I don't have an installer "package" for the old driver, as I do for the new one. I just have a copy of the old driver. I didn't want to start mucking around in the extensions folder without knowing what I was doing. The driver extension is in the folder SSD 115/System/Library/Extensions .
