— Hard drives —
If you're using an IDE (ATA, UDMA) drive, and getting clicks and pops,
make sure that DMA is enabled for that drive. Many drives are
installed without DMA enabled, which can make a HUGE difference in
performance. To enable DMA:
1. Navigate to the Device Manager (StartgSettingsgControl Panelg
SystemgDevice Manager).
2. Click the "+" next to "Disk drives."
3. Double-click on the listing for your hard drive.
4. Go to the "Settings" tab, and make sure that "DMA" is checked under
Options.
5. If you changed the setting, you'll need to reboot the computer for the
change to take effect.
Also, we do not recommend trying to record audio to an IDE slave
drive. IDE controllers can have one master drive and one slave drive.
Many systems have two IDE controllers, each running one master
drive. That's fine. But slave drives can be much less responsive and
can easily cause audio glitches.
Note that SCSI drives have none of these problems. If you have a SCSI
drive, make sure that you're using a good bus-mastering SCSI
adapter. Other adapters, without bus-mastering, do not have
sufficient performance and can cause audio problems.
