100% cpu usage when copying files

[carbon-rod]

hey

im having a problem when i just copy files off of a cd onto the hdd it uses 100% of the cpu and it makes the mouse go all chunky
n e ideas?
i have a p4 1.7
512 2100
gf4 mx 440
win 2000
asus p4pe
40 7200 seagate
20 5400 seagate

estimation...

well maybe the files you copied in was heavy. Hows your RAMs? maybe also that your cpu processor, mighty p4, gets a little bit hotter than normal. When that happens, it'll eventually greatly slow down your entire system...
your computer takes a lot of juice in copying stuff I see..your specs are fine though, but after I scan/analyze my drive C:, and then defrag, all turn up fine and smooth at anything...

Perhaps antivir is trying to scan all the files on the way to your hd?

I experienced massive system lag yesterday (though I do NOT have antivir) when I downloaded (via ftp) 9gb of files from my main computer to a laptop. Internet connectivity got cut off, and halo went 1fps

Roger that, antivirus, can take to much CPU and memory.

Make sure that DMA is enabled for both your HD and CD drive. Also check if any anti-virus software is running real time protecton.

That too!
If pio mode is enabled for either hard drive, cpu usage will go to 100 and the transfer is slow as ????.

hey
i have just enabled dma on my 20 but the files i was copying was to my 40 which was dma enabled i have antivir on and i think it does scan realtime but it doesnt usually take long to scan mp3s which is what i was copying and as for the cpu it was aorund 43 when i started and because of the cpu usage of copying the files when it finished it was up 2 about 52 and the max ive had it to is 55 maby its the mobo? cos my crappy ecs one didnt do it

Try disabling the anti-virus software and trying again, only way to be sure it isn't causing the issue. I know that real time file protect completely kills the IO performance on my file servers at work (and thats on machines that are probably quite a bit more powerful).

Is DMA enabled for the CD drive if you are using that as a source?

[carbon-rod]

yep they are both activated i dunno eh and it only happens when i copy from cd to hdd not form hdd to hdd or lan aha breakthrough it only happens with my cdrom and not my burner it is weird cos my normal cdrom is more expensive than the burner thanks for your help maby ill exchange it or something

Are the HD and CD-ROM drive in question both on the same cable? You'll get faster/more efficient file transfer (less cpu intensive) if the drives involved are on different IDE channels.
