Well, that would be nice but I tested all the options you suggested below 
and my hard drive performance did not improve. Please see to my "Hard Disk 
Performance Optimization" post for details.

Here is the mean (average) throughput I'm getting:
Timing buffered disk reads:  64 MB in  1.87 seconds = 34.22 MB/sec

You may recall that I mentioned dd crashed when I tried to mirror my drive
due to DMA errors Debian was experiencing, so the 4.5 hour backup time 
was with DMA support turned off for both IDE hard drives.
