Do you have USB drives attached?  If so, disconnect them (and any other storage devices that are connected, including memory cards).
my hdd in vostro200 spoilt, so i replaced a new 1TB hdd. no change in the position the sata cables are connected. power up and boot from cd and when i try to install my xp, i create the partition and the pc will assign "H" and the remainding as "I' drive. after i finished the installation, i see that there are removable disks as c,d,e,f and the cd rom as 'g". thinking that i may have make a mistake so i reinstall again, delete all the partitions in my 1TB hdd and created the 2 partitions again, but it still gives me the "H' and 'I' drives. although there is no problem in using the pc but i feel it strange. all these while when i reformated my other oem pc like HP where there were also card readers etc, it always assign the "C' drive for the new hdd. anyone can enlighten this please, thanks
why did not assign "c" drive
