Transfer Mode 

These modes determine the speed at which data is transferred to and from the drive. The Auto 

option automatically determines the correct transfer rates. 

Auto / Standard / Fast PIO 1 / Fast PIO 2 / Fast PIO 3 / Fast PIO 4 / FPIO 

3 / DMA 1 / FPIO 4 / DMA 2 

Ultra DMA Mode 

Enables or disables Ultra DMA Mode.  

Ultra DMA (UDMA, or, more accurately, Ultra DMA/33) is a protocol for transferring data 

between a hard disk drive through the computer s data paths (or bus) to the computer s 

random access memory (RAM). The Ultra DMA/33 protocol transfers data in burst mode at a 

rate of 33.3 MBps (megabytes per second), twice as fast as the previous Direct Memory 

Access (DMA) interface.  

Ultra DMA support in your computer means that it will boot (start) and open new applications 

more quickly. It will also help users of graphics intensive and other applications that require 

large amounts of access to data on the hard drive. Ultra DMA uses Cyclical Redundancy 

Checking (CRC), offering a new level of data protection.
