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. > /dev/hda: > multcount = 16 (on) > I/O support = 1 (32-bit) > unmaskirq = 1 (on) > using_dma = 1 (on) > keepsettings = 0 (off) > nowerr = 0 (off) > readonly = 0 (off) > readahead = 8 (on) > geometry = 2434/255/63, sectors = 39102336, start = 0 > busstate = 1 (on) > > You can time the drive with `hdparm -t /dev/hda`, your results should be > better than this: > > /dev/hda: > Timing buffered disk reads: 64 MB in 2.19 seconds = 29.22 MB/sec 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.
