I just installed a new IDE HD, a Seagate 320 gb ATA/!00 as the Win XP boot drive and immediately noticed it's very slow to copy files from the old drive.
It's the primary master and the old drive is on the other channel. DMA is enabled for both. It seems to be writing at about 3 mb/s. I've run some disk utilities on it but got no errors.
I'm wondering if I should return it.
