WIN XP hard drive speeds etc

[fedge]

Both the HD and the cdrom drives seem to be slow..

on my home machine i can mux and copy files at about 9000kbytes/s

on my inlaws machine (xp) it runs at about 2000-3500

dvd2avi takes up to 20 min for a 2 hr movie to make a dv2 project file... mine would take about 6-7 min for the same movie..


makes no sense

Check DMA in Device Manager.

Could be something basic like being massively fragged. My music drive was horribly fragged (http://www.ogsth.com/images/holyshit_frag.jpg), which after a few run throughs with a defragger responded a bit better.

edit >> what file systems are being used?

it's very possibly to do with drivers too. having the default winxp ide drivers instead of the actual drivers from the motherboard manufacturer.

Or the reverse if you have an Nvidia Nforce2 motherboard.
The default XP IDE drivers are much better then the drivers supplied in the Nforce2 driver set. Actually in the latest release of the Nforce driver set they no longer include the IDE drivers.

But in muxing everything matters, some more then others, CPU Speed, Bus Speed, Amount of memory, Hard drive Speed, etc...

For example I now use only 7200 rpm or faster hard drives. When copying large files I noticed a good deal of difference between the two.

If the computer is Via based then you might be having the Latency Issue that is well known and documented on the AMD side.

So many reasons it could be happening.

my comp has a VIA chipset and AMD processor.. im not sure about the speed of the HD.. since it was a manufactured pc from system max they pry skimped and got a 5400 drive...its a Samsung SV600 3H if that helps..... ive tried to install the via drivers.. but they dont ever seem to want to "take".. the version information always says the same orginal microslut drivers and version numbers.. I DID FORCE THEM TO INSTALL>. i think it works since the computer still works.. but i have no better speed... (I could only force the VIA IDE Control.. not the other two ide devices.. primary and secondary still use the microsoft ones from 2001..

ide speed (http://forum.doom9.org/showthread.php?s=&threadid=43758)
This talks about the problem XP has with the IDE bus. Basically it slows the read/write speed down everytime it reports an error on the chain. And when the errors start to accumulate, it turns off DMA

fedge:

You must check it in device manager. I observed same thing what dvd_maniac mentioned in XP. It simple disabled DMA modes for CD writer. Probably because of some minor cable problem.

Solution was to replace CD-R drive with some other drive (CD, HD, regardless). Boot in XP, wait to recognise new hw. and after that put back standard CD-R drive.

hey ppera2,

you do not need to get that drastic, simply go into the device manager and delete primary and secondary ide and reboot. when it finds them again it will rewrite the registry settings of errors encountered back to default of (0). There is also a regedit you could do too.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}
subfolder 0001 delete MasterIdDataCheckSum SecondaryIdDataCheckSum
subfolder 0002 delete MasterIdDataCheckSum SecondaryIdDataCheckSum

Also I read that when you have a cd or dvd drive connected to the same ide chain as a hard drive and one of them reads errors, it slows down the other one too. So position your devices well...

Thanx maniac :)

I will save those register setting for future.
Those 'drastic' methodes are often by me, because I need to attach foreign HD when somebody brings it to me for data recovery or similar.
