[QUOTE=amolpatil2k;2003668]I have a PC with the following specs:
Core2Duo E4500
Intel 82945G
512MB
80GB (Seagate ST 380815)
DVD Writer (LG H60L)
I don’t get good transfer rates (barely 4x) when writing an ISO file to DVD-R. Could it be because the HDD and ODD are both on scsibus1.
Can a change in BIOS setting put the LG H60L on scsibus2?

It looks like you had connected the SATA ODD to SATA2 (on your system’s motherboard) with your SATA HDD connected to SATA1. This can slow down the performance of both your HDD and ODD because the SATA bandwidth is shared between the two devices. It is recommended to connect the ODD to SATA3 instead of SATA2 on your motherboard; that way the ODD will be on its own channel.
