I have enabled the DMA option on my HD and my cd-rom, everything seem to be okay so far. I was just wondering if this could hurt my system, like hardware or memory.?? I also have a writer but I don't think I will enable the DMA option. any comments?

jay00, it depends on what HD you have and which cd-rom drive you have. Some HDs don't support DMA, when this is enabled it can cause data loss or corruption, in some cases a hard disk crash can even occur. However you don't have to usually worry about this if your hard disk is a 4.3Gb or higher since most of them after the 4.3Gb and including it support DMA.

However for your writer it's best if you disable DMA on your hard disk to ensure best results while writting. To check more about your writer and which settings would be the best for writing go to www.cdmediaworld.com and check out their tips. Hope this helps :-)

Both my HD and cd-rom drive are quite new.  HD-seagate 8.6 and cd-rom drive-infra48x.  I've been running my HD in DMA mode for weeks now and i never get data corrupted, but I just turned DMA mode on my cd-rom yesterday. Could I get data curruption on my Cd-rom? I'm not going to be running my writer on DMA.

I have a infra 48x too and there is no problem with setting it at DMA, your hard disk supports it too so no need to worry about data corruption. However as I said before, for the best results while writing I would turn the DMA off on your hard disk.
