Acer Aspire 5600 5601 AWLMi Intel Duo Processor T2050 hard drive PIO mode
Main problem: My hard drive switches to PIO mode although the preference is and remains ultra DMA mode. I've been having to uninstall the hard drive and then have Windows automatically reinstall it in the correct ultra DMA mode.
Secondary problem: My cursor regularly and periodically freezes for about 20 seconds and I can't do anything until it comes back.

you are trying which is not possible. all optical drives work in PIO mode ... hard disk typically run in DMA mode which is bypassing cpu to access memory directly without calling daddy CPU.... though i am amazed who offered you registry fix for this.
