|
|
I have setup hdparm to set dma on when booting. I check it and it is set. When I try to burn a data dvd-rw with growisofs, dma is then set to off.
Below I have included some information that I hope is useful to someone.
I'm really wondering if I have a problem and should it be writing at a higher speed?
Code: |
lspci |grep -i ide
00:0d.0 IDE interface: nVidia Corporation MCP51 IDE (rev a1)
00:0e.0 IDE interface: nVidia Corporation MCP51 Serial ATA Controller (rev a1)
00:0f.0 IDE interface: nVidia Corporation MCP51 Serial ATA Controller (rev a1)

hdparm -i /dev/hda
/dev/hda:

Are you trying to access the disk while it's being burned.. does it happen in command mode or something?
some drives don't lock reads when writing and it screws things around. |

I myself are not trying to access it. I did forget to say I am using K3B which uses growisofs.
After it has burmed the DVD, I check dma mode with hdparm and it is off. It is on before I start k3b. |

The same happens to me. Sometimes, CDs or DVDs just won't burn! While posting this, i'm burning a dvd and the cpu usage is about 100%.
I noticed this error from dmesg output:
Code: | hda: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error }
hda: cdrom_decode_status: error=0x40 { LastFailedSense=0x04 }
ide: failed opcode was: unknown
hda: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error }
hda: cdrom_decode_status: error=0x40 { LastFailedSense=0x04 }
ide: failed opcode was: unknown
hda: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error }
hda: cdrom_decode_status: error=0x40 { LastFailedSense=0x04 }
ide: failed opcode was: unknown
hda: cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error }
hda: cdrom_decode_status: error=0x40 { LastFailedSense=0x04 }
ide: failed opcode was: unknown
hda: DMA disabled
hda: ide_intr: huh? expected NULL handler on exit
hda: ATAPI reset complete |
Any ideas why is this happening?
Thanks in advance, Luciano. |

I figured out the problem!
I realized I was using an 40w ide cable, so i changed it to an 80w and everything works perfectly now.
Bye. |
