Acronis is very fast for me. Check your DMA, make sure it's set. If using PATA, also check the BIOS, cuz I've personally had Cable Select pick the wrong device as the master, and having the hard drive set to slave (while the optical drive is set to master) can also slow things down...or so I've heard. My new machine couldn't do Cable Select correctly, and doing the jumper-thang fixed a world of problems.
