Other Caching Options
There are several other caching options which may affect your PC’s
audio performance —
•
You may want to limit the amount of “Read-ahead optimization”
performed by Windows. Open the Control Panel (Start
g
Settings
g
Control Panel), and double-click the System icon. Select the
“Performance” tab, and click the ‘File System...’ button. When the “File
System Properties” dialog appears, select the “Hard Disk” tab, and
move the ‘Read-ahead optimization’ slider all the way to the left.
•
In the same dialog (“File System Properties”), you can specify the
“Typical role of this machine.” In most cases, you’ll want it set to
‘Desktop computer.’
•
You may want to disable “write-behind caching.” In the “File System
Properties” dialog, select the “Troubleshooting” tab and check the box
labelled ‘Disable write-behind caching for all drives.’
32-bit Drivers
To obtain the best possible performance from your disk system, use
32-bit drivers. Generally, the Windows installation replaces real-mode
drivers with 32-bit protected mode drivers. However, there may not
have been any 32-bit drivers that were compatible with your hardware
when Windows was released. To check the driver, open the Control
Panel, double-click the System icon and select the “Performance” tab.
If the “File System” status doesn’t indicate “32-bit,” contact the
manufacturer of your disk controller to get a 32-bit protected mode
driver and install it in your system.
