I know it's a different model but found this at Roxio -
In order for the Sony CDU928E to work properly (with any recording software), it must be set as the Master on the Secondary IDE channel. This information was previously documented by Sony.
Buffer underruns are generally caused by a number things:
The performance of your system
Size and number of the files you're recording
Location of the temporary directory and source files
Older device drivers (8 / 16 bit drivers)
Busmastering enabled for the IDE controllers
Applications / TSRs running in the background
Quality of recordable media
General Troubleshooting Steps:
Close all running applications before launching Easy CD Creator by pressing [CTRL] + [ALT] + [DEL] and End Task on all except 'Explorer' and 'Systray.'
Run both Scandisk and Defrag on the hard disk(s) (To run click on 'Start', 'Programs', 'Accessories', and 'System Tools'.)
Clean Temp directory, in \WINDOWS\TEMP - move or delete all files and folders
Make sure no real mode drivers are loading from CONFIG.SYS and AUTOEXEC.BAT (Rename the files to *.BAK or place a REM in front of each driver load statement)
For Win 95 & Win 98 systems: go to the settings tab in Device Manager for each IDE device on your system and remove the check mark in the DMA box. For NT systems extract the program DMACHECK.EXE from the service pack disk (service pack 3,4 or 5), and run it. You will be able to disable DMA on screen.
Update your video driver to current version - check with your video controller manufacturer for details
Make sure the firmware on the recorder is current - most manufacturers publish the latest firmware on their web site
Disable screen savers and ALL power management
Do not multi-task while recording
Do not record from a compressed drive
Log off all network connections
For Win 95 & Win 98 systems, set the following for the CD-ROM properties in Device Manager
In Control Panel, select 'System' icon
Click on the (+) on the CD-ROM
Highlight your recorder listed then click on 'Properties' button
Disable Sync Data Transfer / Enable Disconnect / Enable Auto Insert Notification on the 'Settings' tab
Make sure the C: drive has plenty of free space, recommend about 1 1/2 times the amount you want to record to CD
Try a different brand of recordable media, recommend blank disks with the green or blue dye coating
Create a temp directory on the root of the hard drive with most space available. Change the temp directory that Easy CD Creator uses as the buffer during the record process
For Win 95 & Win 98 systems - check for the following in \WINDOWS\SYSTEM\IOSUBSYS and rename if found:
atapchng.vxd (used by CD changers)
necatapi.vxd (only if you do not have a NEC brand IDE CDROM)
scsi1hlp.vxd
torisan3.vxd (used only by Torisan brand 3 CD changers)
There may be others loaded by various software packages that will conflict, generally from other CD writing or similar products.
For Win 95 & Win 98 systems set the Optimize access pattern to 'No Read ahead', if it's already at 'No Read ahead', try setting it for 'Quad Speed' or higher:
In Control Panel, select 'System' icon
Click on 'File System' button in 'Performance' tab
Change the 'Optimize access pattern for' under 'CD-ROM' tab
Additional Troubleshooting for SCSI Device :
Make sure your SCSI Termination is set properly:
Internal devices only: The device farthest from the controller and the controller must be terminated. Nothing else can be terminated.
External devices only: The device farthest from the controller and the controller must be terminated. Nothing else can be terminated.
Internal and External devices: The two devices farthest from the controller must be terminated. Nothing else can be terminated.
Set the SCSI Controller to the following :
To access Adaptec's SCSI controller setting, press [CTRL] + [A] during the boot sequence. To access non-Adaptec SCSI controller, contact your SCSI controller vendor.
Synchronous Negotiation = disabled
Wide Negotiation = disabled
Ultra or Fast SCSI = disabled
Maximum or DMA Transfer Rate = 5 MB / sec
Disconnection = enabled
