I don't think partion size make much of a difference with ext2 partition, but I could be wrong, the speed difference is probably caused by MS-DOS defaulting to used DMA and linux not, try install the hdparm package with it you can test you HD read speed with 'hdparm -t' and fiddle setting I use 'hdparm -c 1 -d 1 -k 1 /dev/hd?' to set 32 bit IO mode and turn on DMA.
