1. Download the latest update to CD Architect from SONY’s Downloads page. This update is free, and it will contain our latest CD-R drive support.
2. Make sure you have the newest firmware for your CD-R drive. Contact your drive manufacturer or go to their Web site to find out the newest firmware revision.
3. Enable Disconnect and Disable Sync Data Transfer. Go to Control Panel/System/Device Manager, and choose CD ROM. Make sure that the settings for your CD ROM and CD Recorder are as follows: Disconnect should be enabled; Sync Data Transfer should be disabled; and Auto-insert Notification should be disabled. Also, in your SCSI card BIOS make sure that Disconnect says YES for the SCSI ID for your CD Recorder and that Initiate Sync Negotiation says NO.
4. Check to make sure you are not loading DOS ASPI drivers in the config.sys or windows\system.ini files. These can conflict with the system and CD Architect.
a. From the Start Menu choose Run.
b. Type “sysedit” and press OK.
c. The System Configuration Editor will open.
-Choose config.sys by clicking on its title bar. Look for any entry that reads, “Device = xxASPIxx.sys” where ‘x’ is anything. If found, remark them out by typing “rem” before the line (i.e. rem Device=…), and save the file.
-Choose windows\system.ini by clicking on its title bar. In the section [386enh] look for any entry like the above example. If found, remark them out by typing “;” before the line (i.e. ;Device=…), and save the file.
d. You must restart the computer for these changes to take effect.
5. Make sure your SCSI Chain is properly terminated. Improper SCSI Termination may cause various sporadic problems. The proper way to terminate a SCSI chain is to have a single terminated device on each end of the chain. The most common errors are:
a. Terminating a SCSI controller card in the middle of internal and external SCSI devices.
b. Terminating multiple internal SCSI devices, most frequently hard drives.
Most newer SCSI controller cards will auto terminate if necessary. This is not always the case. Some cards need to be manually terminated, either through the use of jumpers on the card or software settings in the BIOS of the card. Check your SCSI controller’s documentation. Remember: the controller card only needs to be terminated if you are using all external SCSI devices or all internal SCSI devices. Termination on internal hard drives can be tricky. They are usually terminated by small jumpers on the underside or back of the drive. Check again, even if you believe things to be correct. It is very easy to miss this.
6. If you have an Adaptec SCSI interface or Adaptec’s EZ-SCSI software:
Update your ASPI layer. To check the version, go to \Windows\System directory using Windows Explorer or My Computer. The file is wnaspi32.dll. Right click on the file and select Properties; then go to the Version tab. It should be 4.01 or later. If you have an older version, an update is available for download from Adaptec’s Web site at www.adaptec.com.
NOTE: Do not install ASPI32.EXE if you have Windows 2000, Windows Me and/or Windows Media Player 7.0 currently installed.
Update your mini-port driver. If you have an Adaptec 29xx or 78xx, the file will be called aic78xx.mpd. If you have an Adaptec card other than one of these, it will most likely be called sparrow.mpd. Make sure that the file is at least version 1.23 or higher. An updated version of this file is also available for download from Adaptec’s Web site.
7. If you don’t have an Adaptec card, check with your SCSI card manufacturer to make sure you have the newest driver.
8. Defragment your hard drives. To make sure data can be transferred as fast as possible to and from the hard drive, you should defragment it often. This will reduce the potential for buffer underruns when writing the CD. You should probably do a “files only” defragmentation before each time you burn a CD. If you are going to create an image file, you may want to defragment the free space on the drive beforehand.
9. Close background programs. This not only means obvious applications like Microsoft Word but also the not so obvious things such as Microsoft Find Fast, System Agent, and Screen Savers. Anything that could be walking around your system while you are trying to write a CD can cause buffer underruns.

10. Create image files. CD Architect writes data directly from the hard drive to the CD. While it is doing this, it is also calculating all of the volume envelopes, crossfades, and mixes in real time. This might be a problem depending on how fast your computer is. If you have a lot of these real-time functions in your CD project, you might consider creating an image file before you burn. An image file is essentially a WAV file that is rendered with all of the mixes, fades, etc., and the PQ information embedded within it. Creating this file and then burning it will greatly reduce the strain on your computer and reduce the risk of buffer underruns.
To create an image file:
Choose Save As from the File menu.
Change Save as type to CD Image.
Name the image file, and press OK.
To open an image file:
Choose Open from the File menu.
Change Files of type to CD Image.
Choose the image file you wish to open, and press OK.
11. Get off of the Network. If your computer is connected to a Local Area Network, disconnect it while you burn your CD. The increased overhead associated with monitoring network connections can sometimes cause buffer underruns. As well, if anybody on the network accesses your computer during a burn, you are guaranteed an instant coaster.
Another network issue has to do with using TCP/IP through a LAN connection. This does not apply if you only have TCP/IP setup using a dial-up adapter. Under Control Panel/Network, double-click the entry that reads TCP/IP followed by the name of your network card and then choose the IP Address tab.
If you are using TCP/IP on a LAN, you should only have Obtain an IP address automatically checked if your network has a DHCP server. This server automatically assigns IP addresses to client machines. If you have this option checked but you do not have a DHCP server on the network, Windows will freeze for a few seconds periodically as it attempts to obtain an IP address. This will definitely cause buffer underruns if it happens during a burn.
There are many network issues so the best solution is not to use a networked machine for CD burning. If you must use a networked machine for CD burning, the best thing to do is physically disconnect your network connector on the back of the machine and then start up Windows. This guarantees that you will not be on the network. However, the DHCP problem described above may still exist even if you physically disconnect yourself from your network.
12. Try burning at a slower speed. If you’re burning at a speed of 4x or greater, try burning at 2x. It is probably not necessary to burn at 1x; 2x seems to be the optimal speed at which to burn CDs.
13. The CD-R media you are using may be the wrong type or may be defective. Try using a different brand of CD-R media because different drives work best with certain types of media. Make sure you’re using the media-type recommended by your manufacturer if they have a recommendation. Bulk varieties that come on spindles with no jewel cases can often have higher error rates.
14. Your drive may be failing. If you are unable to burn CD’s properly with any software you try then it may be time to replace the drive.
