UDMA - on & off !?

I uses Intel Application Accelerator to ensure all my drives run on correct transfer mode. With the program, all drives are running fine. 2 harddisks at UDMA-5 and 2 burners (451@832-VS0A & cd) at UDMA-2.

however, with Nero InfoTool, all the slave drives are DMA off!! It’s also the same in Nero log file :-

=== Scsi-Device-Map ===
DiskPeripheral : MAXTOR 6L080J4 IdeChnDr Port 0 ID 0 DMA: On
DiskPeripheral : Maxtor 34098H4 IdeChnDr Port 0 ID 1 DMA: Off
CdRomPeripheral : LITE-ON DVDRW SOHW-832S IdeChnDr Port 1 ID 0 DMA: On
CdRomPeripheral : RICOH CD-R/RW MP7200A IdeChnDr Port 1 ID 1 DMA: Off

anyone knows a solution to ‘fix’ this??
or is it just the usual bugs with Nero :confused:

Nero InfoTool is likely just mistaken. IAA causes a lot of complications with many different softwares.
