My old DVD-RW drive gave up the ghost a couple of days ago. I bought a new drive and fitted it. This drive made the computer very slow while reading. Took it back and got a different model.This drive will only read at 3 or so speed. If I put my old drive back in it reads at a very fast rate. I have uninstalled and re-installed the drive and IDE channels within windows.Changed the IDE cable twice. The BIOS reports all is well, so this has me really stumped for an answer. DMA is on and not PIO mode.Any help will be appreciated before I lose all my hair.
Are you sure that it is being permenantly changed to DMA, I read somewhere that although you change it it can change itself back again, I had this and did a download that cured it, afriad I cannot remember where from.
