When I write to this disk for a while, I see this in dmesg (only once so far): [31230.223504] ata6: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ 0xb/00/00 [31230.223511] ata6: status=0x51 { DriveReady SeekComplete Error } [31230.223515] ata6: error=0x04 { DriveStatusError } Is there some sort of smart testing going on constantly? I only get 26-27MB/s on this 400GB/SATA/16MB/7200RPM drive. I use smartmontools to do a daily test. However, even with smart disabled, I get: # hdparm -t /dev/sde /dev/sde: Timing buffered disk reads: 78 MB in 3.06 seconds = 25.46 MB/sec Does anyone know if this drive has problems in Linux or something? [ 6.895914] Vendor: ATA Model: WDC WD4000KD-00N Rev: 01.0 It just seems to be that drive that has issues. Here is a 400GB seagate ata/100: /dev/hde: Timing buffered disk reads: 172 MB in 3.02 seconds = 56.91 MB/sec Here is a 74GB raptor SATA/150: /dev/sda: Timing buffered disk reads: 204 MB in 3.03 seconds = 67.38 MB/sec Both drives above are on the same system, so my question is what exactly is wrong with the WD drive? Is it a Linux issue, a drive issue, or? Does anyone else use this drive, what rates do they get?

I've seen similar errors soon after bootup on a 400GB PATA Seagate drive, but they have mysteriously disappeared so I haven't tracked them down. Have you checked if there is a difference in the hard disk parameters? hdparm -i <drive>. For some insane reason I haven't tracked down, drives not explicitly set to known values may not contain "great values". My "readahead" value seems to boot with a value of "256" for all of my drives. Is this not a bit "excessive"?

Wow.. that does look a bit HUGE. Thanks for pointing it out, I'm resetting mine back to 128 for now. > Justin Piszcz wrote: >> When I write to this disk for a while, I see this in dmesg (only once >> so far): >> >> [31230.223504] ata6: translated ATA stat/err 0x51/04 to SCSI >> SK/ASC/ASCQ 0xb/00/00 >> [31230.223511] ata6: status=0x51 { DriveReady SeekComplete Error } >> [31230.223515] ata6: error=0x04 { DriveStatusError } >> >> Is there some sort of smart testing going on constantly?

Some drives suck at sequential reads, in favour of doing random seeks very very well. Basically, the on-drive seek algorithm may not favour doing much read-ahead. Try "hdparm -A1" and see if that helps. |

Turned out I had too many devices in the box, I have removed them now, still getting those pesky drive errors though, I will try the hdparm soon, thanks.

> > Is there some sort of smart testing going on constantly? I only get 26-27MB/s You can find out using `smartctl -data -a /dev/hdX`; if there is a SMART test going on, there should be info about its status. > #13 Vendor offline Completed without error 00% 0 - > #14 Offline Completed without error 00% 0 - > #15 Offline Completed without error 00% 0 - > #16 Offline Completed without error 00% 0 - > #17 Offline Completed without error 00% 0 - > #18 Offline Completed without error 00% 0 - > #19 Offline Completed without error 00% 0 - > #20 Offline Completed without error 00% 0 - > #21 Offline Completed without error 00% 1 - > A little bit more below the values, usually.

Also, you may have to monitor this for a while as I've seen when a drive is not recognised in the smartctl database, then it doesn't show it's progress, only when it finishes checking does it show something in the selftest log.
