1. IDE Cable.
•40 Pin, 40 conductor cable for U/33 (PIO Mode 4).
• Or 40 Pin, 80 conductor cable for U/66/100 (PIO Mode 5+).
2.Controller card or On Board IDE Controller.
Handling
•Do not drop.
•Do not touch the connectors, exposed circuit board or any electronic components.
•Before handling the drive, discharge any static electricity from you by touching any unpainted surface of your computer chassis. (Preferable use a wrist grounding strap)
Considerations
1. IDE Controller.
• One IDE Controller can have two channels.
• Each Channel can have two Hard Drives/devices.
• A standard Controller will usually be equipped with 2 channels, so it can have 4 devices.
• The first channel is the Primary Channel called IDE-0.
• The second channel is the Secondary Channel called IDE-1.
• The first device will be the Master Device-0.
• The second device will be the Slave Device-1.
• If you have four channels, consider placing the CD-RW on the Tertiary Channel IDE-2.
• If you have four channels, consider placing the CD-ROM on the Quantanary Channel IDE-3.
• If possible do not place the CD-ROM on the same channel as the CD-RW, if you are planning on doing CD copies. If you must, you may be able to negate the performance impact by "First copying to disk".
3. Device.
• Some CD-ROMs must be set as Slave Device-1.
• Some CD-ROMs must be on the Secondary Channel IDE-1.
• Some IDE Controllers, require the CD devices to be on the Secondary Channel IDE-1.
• Some CD-RWs must be set to Master Device-0.
4. Installation.
•Make sure you have an available slot to install the CD device in the case.
•Make sure you have an available device setting on a channel.
Installation Procedure
1. Turn off your computer.
2. Remove the cover as instructed by your computer manual.
3. Discharge static electricity previously mentioned in the "Handling Instructions".
4. Unplug your computer.
5. Note mounting position of existing drive(s) and cables.
• If replacing a drive or cable, then remove it.
6. Record model number, part number, and serial number for future reference.
7. Set the jumper. (Follow manufacture recommendations)
• If it will be the Master with or without a Slave device set to Master.
• If it will be a Slave device set to Slave.
8. Attach the IDE cable.
• If this is a 40 pin 40 conductor, then attach the system connector of the cable to the IDE port/channel on the mainboard or controller card. The system connector is the connector at other end from the other two connectors.
• If you have a 40 pin 80 conductor cable, then attach the drive to the appropriate color coded connector.
• 1. Master is a black connector.
• 2. Slave is a gray connector.
• 3. System connector is a blue connector.
Note - if using the jumpers on the drive to set master/slave, it does not matter which connector you use.
9. Attach the power supply cable to the CD Device. Match the connector bevels.
10. Mount the device securely, using 4 screws.
11. Verify all attachments.
12. Replace the computer cover.
13. Plug in your computer.
14. Power up the computer.
15. Go into the BIOS and ensure it has been detected. Preferable set all IDE connections to auto.
16. Save your BIOS settings and exit.
17. Boot up normally into your OS.
At this point the device is ready an available for use.
Notes
Document Revision 1.1
Updated 12/2004
Changes: Removed section recommending Optical drives not be shared on a channel with hard drives. With independent memory timing on modern UDMA capable IDE channels, each device will operate at its maximum rated/recognized speed when in use.
General comments: if you plan on doing lots of direct cd/dvd duplication from one optical drive to another, you should place them on different IDE channels/cables to maximize thruput. Since IDE is a parallel technology, only one device on the channel can be utilized at a time.

•Use a fast, AV-friendly hard drive (i.e. one that doesn't do slow thermal re-calibrations). Pretty much all drives sold in the last couple of years fall into this category.
•Record at a slow speed.
•Don't do anything else with the computer while recording.
•Don't record from a file server.
•Defrag your HD regularly, especially if you're doing on-the-fly recording.
•Record from a disc image file rather than on-the-fly.
•Depending on your setup, putting the recorder and your hard drive on separate SCSI controllers may be necessary.
•Keep your CD-R cool. Sometimes the drives fail when they overheat, with a buffer under-run or an inability to finalize a session.
If a buffer under-run occurs, you may still be able to use the disc with multisession CD-ROM drives by closing the session and starting another, assuming there's enough space left on the CD, and assuming your pre-mastering software didn't choose to finalize the disc for you.

| | | When burning audio-cd's it is absolutely critical that the data-stream from the harddrive to the CD-writer is as continuous as possible. The CD-writer has an internal memory-buffer to compensate for small gaps, but if your harddrive or your CPU is interrupted for to long, the CD-writer will run out of data. Because the CD-writer cannot wait, this will cause gaps and noise in the music, or in the worst case, it will ruin the entire disc. Buffer Underrun errors are a big problem for cd-burners.
The source of the problem
Windows is a multi-tasking operation system, meaning it can run many programs simultaneously. The CPU, however, can only do one thing at a time. To solve this problem, Windows divides the CPU-time into small slices and gives each running program a short period of time to execute, before the CPU is handed over to the next program. The more programs you run, the smaller each time-slice gets. If the slices are to small, there may not be enough time for the burning-software to fill the buffer on the CD-writer.
Just like the CPU, the harddrive cannot read everything at the same time. If, for example, some antivirus software or a screensaver starts in the middle of your cd-burning-session, the harddrive may get occupied with other things and stop reading CD-data.
The solution
What can I do about prevent those "buffer underrun errors"? There are a few things you should always do before burning audio-cd's:
1. Reboot the computer before you begin to make sure the operating system is completely stable (You never know after running a few games).
2. Terminate all programs but the cd-burning-software including those running in the background.
3. Don't use your CD-writers maximum burnings speed. If your writer can burn at 4x use 2x, if can handle 8x use 4 and so on. This way, the CPU will only have to send half as much data to keep the buffer full.
4. Try increasing the priority of the CD-burning software. You may have to try a few different settings before you find the optimal priority for your system.
5. Burning on the fly is not recommended. If there is a hiccup in the cd-rom you're burning from, you'll get a coaster. Always cache to harddrive before burning. (This is usually an option in your burning-software)
This may not be the final solution for all systems, but it could save some time troubleshooting.
