Hi there,
I'm running a centos 5.2 (with a centos 5.3 kernel) on a box with a samsung 1To green edition, and this disk looks a bit slow to me and it's not recognized by hdparm : # hdparm -iI /dev/sda /dev/sda: HDIO_GET_IDENTITY failed: Invalid argument HDIO_DRIVE_CMD(identify) failed: Invalid argument
# hdparm -tT /dev/sda /dev/sda: Timing cached reads: 2252 MB in 2.00 seconds = 1125.57 MB/sec Timing buffered disk reads: 94 MB in 3.05 seconds = 30.81 MB/sec
I've got a samsung 640go on my desktop running ubuntu (kernel 2.6.27-11), hdparm -iI is working and benchmark is a lot better : $ sudo hdparm -tT /dev/sda /dev/sda: Timing cached reads: 2392 MB in 2.00 seconds = 1196.00 MB/sec Timing buffered disk reads: 226 MB in 3.02 seconds = 74.81 MB/sec
the green HD is a 5400rpm, though the other one is 7400rpm, but a factor 2 in performance between them looks very strange to me. As the green 1 To disk is not identified by hdparm I think it's not configured properly.
Any hint to make my 1To disk flying like the other one ? :)
cheers,
David

more likely to be a problem with support for the specific SATA controller than the drive itself.

You do not give enough info to help. If kumn.gov.kw is the domain we are talking about then go fix the errors shown here: http://www.intodns.com/kmun.gov.kw
no file has been modifies for long time
So that just means that it has been broken for a long time. :-)
FWIW, a lame server means that it is not authoritative for the domain that you are requesting info for.
