I have a hard drive that is showing as Ultra DMA Mode 3 (other times it shows
as Multi-Word DMA Mode 2) in the Primary IDE Channel Properties . I believe
this should be showing as Ultra DMA Mode 4, which corresponds to 66.7 MB/s.
Here is what I have in my system:
Windows XP
ABIT KT7 Motherboard (Supports Ultra DMA 66)
Maxtor 52049U4 (Google - UDMA 66) - attached to end of cable.
80 Conductor Cable
I talked with maxtor technical support and they told me that it is very
unlikely that a faulty drive would go down to UDMA 3, then to Multi-Word DMA
Mode 2.
I did a "Pause Break" at at bootup and found the following information:
First Screen: Maxtor 52049U4 DAC10SC0
Second Screen: Prim. Master Disk: LBA, ATA66, 20491MB
So it looks like at bootup the drive is detected as ATA66 but once in
Windows XP, it is beeing detected as UDMA 3 OR Multi-Word DMA Mode 2.
I installed the VIA Hyperion 4in1 version 4.43 (VIA Bus Master IDE
Controller Date 7/1/2001, Driver Version 5.1.3597.0.)
The drive still go down to UDMA 3 or to Multi-Word DMA Mode 2.
Appreciate your suggestions, on what else I can look for so that this drive
could be Ultra DMA Mode 4.
THANKS
