2big - Operating system does not recognize LaCie virtual drives.

 
  • 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.
