It could very well be hardware problems, if it used to work and suddenly didn't. Do you get any errors in /var/log/messages from the kernel ide driver? Regards Anders On Friday 15 June 2001 23:08, Johannes Bertscheit wrote:

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).

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!) ;-) -----Original Message----- From: Johannes Bertscheit [mailto:jbertscheit@web.de] Sent: Friday, June 15, 2001 2:08 PM To: 'Xlvaro A.
