Udma
Hello, udma5 is ATA100, your right in saying your SATA is running at 150 (or 300, you may have a jumper on the drive). Would you like a full explanation of why your drive is 150 or 300? Check your Disk drives in the Device Manager, it's probably listed as SCSI.
ATA is 'Advanced Technology Attachment', SATA is a serial connection and is the successor to ATA, they run differently.

Martin
