2. Check to see if X windows is running by entering the following:
ps aux|grep X
If X windows is running, stop the application since it may cause a
conflict with Asterisk.
3. Check to see if your IDE hard drives are running with DMA levels set.
Advanced users can perform an hdparm on your hard drive interface.
Check the current mode using this command:
hdparm -vi /dev/[IDE Device]
Use this command to set the drives into UDMA2 mode:
hdparm -d 1 -X udma2 -c 3 /dev/[IDE Device]
If you are still having problems, contact your reseller from which the
card was purchased, or Digium Technical Support at 1.256.428.6161.
Use hdparm with caution as the man page states that hard drive
corruption can occur when using incorrect settings. Please
review the man page for hdparm and make sure you understand
the risks before using this tool.
