Recently I've added a WD3200JB HD (IDE 8MB buffer) to my 5-years old computer. It is an 1.2Ghz AMD, ASUS A7A266. My primary HD is a 40GB IBM HD and I used to have a WD800JB as well (replaced it with the new 320GB).
The problem is that the new 320GB drive works very slow. HD Tech tests show read time of ~2MB/s. chkdisk is OK, no bad sectors. The drive is formatted in NTFS and I'm using Windows XP SP2.
I think its some kind of a compatibility issue with my BIOS. The BIOS is configured AUTO for both Master and Slave devices but when I look at the 'Primary IDE Channel Properties' I see that 'Device 1' 'Current Transfer Mode' is 'PIO Mode' although the Transfer Mode is set to 'DMA if available'.
Second screen when I boot shows a strange thing. It seems as if it doesn't recognize my Slave drive: 'Pri. Slave Disk: None'. When I go into the BIOS it recognizes the HD but the 'Maximum LBA Capacity' is '8455MB' whereas for the 40GB IBM drive it is 41???MB. Is there a limitation issue here?
Do I need to update my BIOS? If so maybe it's better to put the HD as an external one (USB) and not risk BIOS update failure (never done that before and I've heard it's quite dangerous)?
Thanks a lot for any help.
