Driver not found for additional promise device listed when loading Maxtor SATA controller driver

August 5th, 2009 No comments

After installing the SATA card and booting into Windows, the Add Hardware Wizard will prompt for loading a driver for a "storage adapter". This process is similar to loading the drivers for the ATA/133 card and should be successful when you point the wizard to the Maxtor SATA drivers, wherever they are located on the machine.

Once complete, the Add Hardware Wizard will prompt again to load driver support for a "Promise SATA Console Processor Device". You won’t be able to load a driver for this device so just ignore it. Cancel the Add Hardware Wizard.

After this is done, the Device…

I have a SCSI RAID controller and the drives keep dropping offline

SCSI Raid Controller I have a SCSI RAID controller and the drives keep coming up marked dead/off-line. I can return the drives on-line again, but why is this happening and what can I do to fix it?

Drive randomly marked dead (off line) by SCSI controller.

There are many reasons why a SCSI controller or operating system marks one or more drives off line. Here is a list of common issues, likely to cause a drive to be remarked off line–dead.

It’s important to make sure the cabling, termination, and drive enclosure hardware is suitable based on SCSI specification–or as required by your configuration. Use…

What should consider when selecting drives for use in a SCSI RAID configuration?

SCSI Raid Most SCSI RAID controllers will accept different kinds of hard drives. The hard drives should match in capacity points and rotational (RPM) speed. At best, all drives in an array will be identical–at the same firmware revision level.

RAID can be used with any size hard drive. The smallest capacity drive will determine the largest logical volume size for all drives in the array.
Whenever possible select drives from an approved vendor drive compatibility list. This ensures that the hard drive is tested, and should function reliably with your SCSI RAID controller. Untested configurations ’should work’ too. But for best results, select only tested and…

What do I need to consider when selecting drives for use in a RAID configuration? Can two different hard drives be used in a mirroring or RAID array, or must they be identical brands and models?

Hard drives for RAID. Mix hard drives in a RAID array?
