All, Had an HR34, swapped it out for a HR54 yesterday. The Vantec Nexstar RAID Box worked fine with 2 Seagates (each 3TB) in RAID 1 with the HR34. Not so with the HR54. Had to switch to a single drive (WD AV 3TB) and a Voyager S3 dock. Have found one RAID 2 disk box in another forum that apparently works with the HR54 but apparently RAID boxes working with the HR54 are the exception, rather than the rule.
