I just put in a second hard drive (Maxtor, 250GB, ultra ata/133) into my dell dimension 4550 as primary slave. The drive only operates in PIO mode, which is extremely slow. I have been trying to enable DMA mode without success. The following is what I've tried:
1. Checked the jumper settings; both hard drives are cable select.
2. Verified that the new drive is fine using Maxtor's testing utility.
3. Changed dell cable to the cable that came with the new drive.
4. Uninstalled primary IDE channel driver and let XP detect the drives and reinstall the drivers.
None of these works. Related to this is an odd thing that the BIOS doees not recognize the devices on either primary or secondary slave (I have CD-RW drive on secondary slave), but I can use the slave drives in XP. I have XP Professional SP2 on my system.
By this time, I am pretty much desperate! Any help is appreciated!!!
