321425	2005-02-04 07:40:00	Could someone please give me some advice on how to test the performance of a cd-rom on my desktop (athlon2.5 winxp home 512mb.) I have a cd-r and a cd rom and the cd rom often stops or stalls reading while either... copying large files from cd-rom to my hard drive, watching svcd's or general use. It also slows my computer to a relative stop when inserting a cd in to read from. This has been a very fustrating problem. It sometimes runs fine which makes me think that maybe its over heating ?? when its having problems. Any ideas, suggestions are as always appreciated. Mantis.	Mantis (3703)

Control Panel -> System -> Hardware tab -> Device Manager button -> expand IDE Controllerss -> and get the properties on secondary IDE channel -> Advanced settings tab -> Current Transfer mode(s) I'm assuming that your cd writer will be on secondary channel, if not look on the primary channel. If it isn't saying DMA mode in there and is using PIO then it will really be poor (I have a DVD reader that will run like an absolute dog if it is using PIO). You might need an updated motherboard driver if it doesn't stick to using DMA. ms article (support.microsoft.com)	gibler (49)

If it isn't saying DMA mode in there and is using PIO then it will really be poor (I have a DVD reader that will run like an absolute dog if it is using PIO) . You might need an updated motherboard driver if it doesn't stick to using DMA . I have two cd drives installed in my machine . 1 x cd-rw and 1 x cd-rom My secondary IDE settings are as follows . . . Device 0 Current Transfer Mode(s): Ultra DMA mode 2 Device 1 Current Transfer Mode(s): PIO Mode only (with the option to goto DMA) How can I tell which device is 'Device 0' and which is 'Device 1'? and is my cd-rom running as 'Device 1' with PIO mode and is this causing me my grief?? How will I know if I need to update any drivers? and if I do could someone please give me a quick 'how-to' . Is it a good idea to set a system restore point before I do it? Anything else I need to be aware of? Thanks everyone for your help!!! Mantis	Mantis (3703)

Thanks Gibler, Is there anyway to access this info through windows, or do I have to reset and enter bios? Mantis.	Mantis (3703)
