OK - it does look like the drive so far, but the unbuffered speeds look like
DMA is turned off. Let's see if that helps:
hdparm -v /dev/hda will tell us how the drive is set up
hdparm -c 1 -d 1 /dev/hda should enable DMA if it's off
hdparm -tT /dev/hda will test speeds again
(Thanks for the German translation!) ;-)

How about
hdparm -tT /dev/hdwhatever
and provide back the results. If the buffered speed is fast, but the actual disk speed is slow, it could be the disk itself. If both are slow then it's the PC itself.
pp hdparm -tT /dev/hda #my bad disk /dev/hda: Timing buffer-cache reads: 128 MB in 1.10 seconds =116.36 MB/sec Timing buffered disk reads: "Der Wecker klingelt" (the bell rings) {it seems he gets a timeout} pp hdparm -tT /dev/hdd #my good disk /dev/hdd: Timing buffer-cache reads: 128 MB in 1.00 seconds =128.00 MB/sec Timing buffered disk reads: 64 MB in 24.50 seconds = 2.61 MB/sec So its the drive - and the reads are soo slow - but why is the drive so slow? Hardware or Software (Driver) problem or drive settings? I have this problem only since some days ago and I have nothing changed in the configuration (except some side effects that I not know). ____________________________________________________________________________ __ Ferienklick.de - Jede Menge Urlaub auf einen Blick!
