 |
|
Hi,
| Code: |
home ~ # hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 3112 MB in 2.00 seconds = 1555.46 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device
Timing buffered disk reads: 162 MB in 3.03 seconds = 53.47 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device
home ~ #
|
Are those "Inappropriate ioctl for device" errors normal ? I seem to be getting them on almost all hdparm options, even simple things like:
| Code: |
home ~ # hdparm -i /dev/sda
/dev/sda:
HDIO_GET_IDENTITY failed: Inappropriate ioctl for device
home ~ #
|
The HDD is a Seagate Barracuda 7200.7 160GB. |

Unfortunately, you can't use hdparm (or hddtemp, or similar) on SATA devices yet.
Try on an ide drive and you shouldn't see any problems.

O, shit.
FYI, I found this on hdparm's freshmeat page.

SATA drives in the 2.6 kernel are handled by the new "libata" SCSI driver. If you add the "ATA passthru" patch (from Jeff Garzik) to your kernel, then hdparm can work with those drives.
Some flags, like "-d", are not supported by libata. Currently, ALL SATA hard drives use DMA, so there is no need for -d. But eventually libata will have to implement ATA PIO (for CF cards..), and at that time it may (or not) begin to support the "-d" flag.
|
So it should be working with some kernel patching.  |

I forgot to mention sdparm, which some users have reported as been quite usable with SATA drives, look on the forums for details.
Haven't tried it myself yet.

Nice find!
From the mentioned developer; http://linux.yyz.us/sata/, and the patches(?), http://www.kernel.org/pub/linux/kernel/people/jgarzik/libata/.
It's probably only a matter of time before it's added to the kernel.
The one which really interests me, from http://linux.yyz.us/sata/software-status.html
| Quote: | SMART support
SMART support will be integrated very soon. SCSI T10 committee assigned the necessary opcode numbers for ATA passthru (SMART support requires this, in libata). Now only a few small tweaks are needed before this can be integrated into mainline.
There are also some lingering reports that using SMART commands while the disk is in heavy usage leads to timeouts and other failures. This needs to be investigated. |
This was updated only 6 days ago, and refers to 2.6.13-rcX, so things are definately moving along.

It is good to see that things are moving along. I hope the patches go into the mainline kernel soon.  |
