- Verify HBA BIOS recognizes empty LaCie Two Big.
- Before reconfiguring the mode of operation, use the operating system’s Disk Manager to delete partitions on the volume.
- Ensure the HBA driver is current.
Troubleshoot driver:
- Verify driver active status. For Windows, the Device Manager should show the SCSI icon next to the HBA. For Mac OS X, the Disk Utility should show a SCSI Connection ID for the virtual disks on the physical hard disk drives. Error messages during the driver installation would have indicated issues.
- Resolve resource conflicts (IRQ, DMA, or I/O).
- Identify maximum SATA disk drive capacity supported by the operating system and ensure the volume size meets the limits.
- Verify port multiplier (PM) support in the HBA.
