Hi Carlos: Thankf for your reply.
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.
Probably. Bu why don't you use k3b instead of a windows in
Thanks. I read hdparm man several times but it was not clear for me that -d also reports dma status. For hdparm -d -c -u /dev/hdd I get: /dev/hdd: IO_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) Is this good or bad (for unmaskirq and IO_support)? linux thing? According to my knowledge neroLINUX is a native linux program. I had several problems with k3b before. Unfortunately there is not a decent GUI cdburning software for linux. All of them ruins directory dates on burned media. But this would be a different topic.
1. What can cause that dma is turned off?
Check the kernel log.
Is the /var/log/messages file the kernel log? Or dmesg? I found lines in /var/log/messages like these: kernel: hdc: irq timeout: status=0xd0 { Busy } kernel: ide: failed opcode was: unknown kernel: hdc: DMA disabled kernel: hdc: ATAPI reset complete kernel: hdc: tray open kernel: end_request: I/O error, dev hdc, sector 64 kernel: Buffer I/O error on device hdc, logical block 16 kernel: hdc: tray open kernel: end_request: I/O error, dev hdc, sector 68 and: kernel: hdc: drive_cmd: status=0x01 { Error } kernel: hdc: drive_cmd: error=0x04 { AbortedCommand } kernel: ide: failed opcode was: 0xec kernel: hdd: drive_cmd: status=0x51 { DriveReady SeekComplete Error } kernel: hdd: drive_cmd: error=0x04 { AbortedCommand } kernel: ide: failed opcode was: 0xec syslog-ng[2053]: STATS: dropped 0 kernel: hdc: irq timeout: status=0xd0 { Busy } kernel: ide: failed opcode was: unknown kernel: hdc: ATAPI reset complete kernel: hdc: tray open kernel: end_request: I/O error, dev hdc, sector 64 kernel: Buffer I/O error on device hdc, logical block 16 kernel: hdc: tray open kernel: end_request: I/O error, dev hdc, sector 68 kernel: Buffer I/O error on device hdc, logical block 17 I don't know which of these report problems and which are normal. However recently I had also bootup problems. At certain point boot hangs and I have to reset. I can't remember the messages at which boot hangs (not always the same) but next time I will write it down. Couldit be a problem with the MB or bad wiring?
