I have a 40gb Western Digital HD and i just installed an 120gb ATA Maxtor HD. When i transfer a 180 mb file from the WD to the Maxtor it takes a couple mins and it lags my computer at 100% cpu usuage. When im dling a file to the Maxtor Hd at 160 k/b its lags my computer also. My computer is running at 2.4ghz, 512 ram, WD Hard Drive is my master and the maxtor is my slave both using the same cable. Do i need more memory? A different cable? Any infos on how to fix this is appreciated.
