In trying to troubleshoot some other issues I ran the command hdparm and this is the output I got

Code:
linux-bif8:/home/jonw # hdparm /dev/sr*

/dev/sr0:
 IO_support    =  0 (default)
16-bit)
 HDIO_GET_UNMASKINTR failed: Inappropriate ioctl for device
 HDIO_GET_DMA failed: Inappropriate ioctl for device
 HDIO_GET_KEEPSETTINGS failed: Inappropriate ioctl for device
 readonly      =  0 (off)
 readahead     = 256 (on)
 HDIO_GETGEO failed: Inappropriate ioctl for device
This is on a OpenSuSE 11 x64 install with a mixed sata/ide board. The ide ports are connected to dvdr drives. I can provide any additional information requested. How can I get this command to run correctly or to fix the drives so this runs correctly.

On an interesting note this command works fine under the 32 bit OS but the computer freezes all the time with 32 bit OpenSuSE.
