 |
|
Hey all, when I did a hdparm I got some funky messages.... any ideas?
| Code: | astral ian # hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 2832 MB in 2.00 seconds = 1415.51 MB/sec
BLKFLSBUF failed: Operation not supported
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Operation not supported
Timing buffered disk reads: 206 MB in 3.00 seconds = 68.59 MB/sec
BLKFLSBUF failed: Operation not supported
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Operation not supported

I'm using the VIA SATA module on the 2.6.9-ck1 sources. Thanks! |

You probably tried to set things that the libata driver does not support, like DMA. Because you're using you sata drive in a scsi sort of way, you get no DMA, but it doesn't matter anyways, because libata is as fast if not a faster implementation of sata.

I get these messages too and exactly the same speed  . Anyways, isn't the Support for SATA underneath the ATA/ATAPI/MFL/RLL support in the kernel deprecated. I think libata (the one under low level SCSI drivers) is the best way to go for SATA drives even though it gives some strange error messages. Also, how do you ensure you aren't trying to set stuff like dma for your libata drives. I don't remember specifying hdparm -d 1 for /dev/sda anywhere. |

| I get those messages too, but I assumed it was because I was using raid. I have the same SATA controller as you. |

You more than likely have /etc/init.d/hdparm set to start on boot. You can just do | Code: | | rc-update del hdparm |
