I am running RedHat 8.0 on a Dell Dimension Desktop 8200 with a DVD-ROM drive as my /dev/hdc (/dev/cdrom) device. Whenever I try to run the command below on my cdrom, also /dev/hdc, I get the following...
[EMAIL PROTECTED] sbin]# ./hdparm -d1 /dev/cdrom /dev/cdrom: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) I get the exact same message when I do this command on /dev/hdc as well... [EMAIL PROTECTED] sbin]# ./hdparm -d1 /dev/hdc /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) [EMAIL PROTECTED] sbin]# I am logged into KDE as 'alan', then I do 'su' to root in a bash shell. When I execute the command above, I get the message 'Operation not permitted'. I don't quite understand why because I'm logged in as root. Any thoughts??
