Can you tell me something about this device? [ 49.045635] ata2.00: ATA-6: Config Disk, RGL10364, max UDMA/133 [ 49.051677] ata2.00: 640 sectors, multi 1: LBA [ 49.056321] ata2.00: configured for UDMA/133 It seems like it does not support the 'check power mode' command. Can you post a text file attachment, containing the output of 'hdparm --Istdout' ? Jeff
