I have suse 10.1. The system has a cd-rw and a dvd-rw drive. After booting the system Yast dma status check reports that for both drive the dma is on. After a certain time checking again Yast reports that dma is off for both drives. If I want to turn dma in Yast it gives an error message:
"An error occured while activating the changes. Cannot set required mode '%1' for device %2."
At the same time according to hdparm dma is on:
# hdparm -i /dev/hdc
Forget Yast. Use: hdparm -d /dev/hdc Or hdparm -d -c -u /dev/hdc to see the state. Then use "- 1" to activate if possible.
NeroLINUX also claimed that dma was off, and burning a regular dvd took 40 min when the speed was set to 6x so I concluded that dma was off. (Is that correct?)
Probably. Bu why don't you use k3b instead of a windows in linux thing?
Questions: 1. What can cause that dma is turned off?
I once had a SUSE box, DMA was off on the drive, I switched it on, it stated that turning it on could cause data loss. I turned it on anyway and it pulped the partition. Suppose there's no risk with a CD drive but worth a consideration on a hard drive. Matthew
