I got the drive from newegg.com and installed it in my dimension 8400 together with a NEC 3520 in a same (only) IDE channel. I am using windows XP pro.
- If the drive option (in the bios) was set to combination mode, two SATA HDDs (plugged in SATA ports 1 and 3) were identified as in the primary IDE (one slave, one master) in UDMA 5 (SATA ports 2 and 4 were not available in the bios setting in this mode). The liteon and nec drives appeared in UDMA 4 and UDMA 2 respectively as I assumed (in the secondary IDE channel). However, the HDDs ran quite slowly because of no SATA controller.
- Then I changed to raid autodetect /AHCI mode, the HDDs worked perfectly, very fast with a SATA controller in device manager. Both the optical drives were identified in the unique (primary) IDE channel but in UDMA 2. The burst rate I checked was only 24MB/s for the liteon drive :a (it is always over 37MB/s in UDMA 4). I think, this burst rate is not enough to burn DVD at 20X.
I’d like to keep the liteon drive in UDMA 4 while I still can use the advantage of AHCI mode for SATA HDDs. Help me please!!!
(In raid autodetect/ATA mode, there was no SATA controller but both the liteon and nec drives were in UDMA 2)
