new hard drive installation

[Truckman36]

have installed a new segate hrd drive in a Dell Dinension 4400 computer..Dell said the old WD 40 gig hard drive was bad..the computer would not boot from the old drive..my question now is how can i transfer the info from the old WD hard drive to the Segate hard drive?? both are installed and have placed Windows XP on the new hrd drive -- both drives show up in bios but cannot find any way in Disk Management to transfer info from one disk to the other..any help, please? or if i find the old disk still works how do i share the info from one disk to the other?? this is not my computer--a friend's.. please help..Thanks, Guys

Do they both show up in Windows Explorer? If so, just drag and drop.

Thanks, glc...The guys at Dell told my friend her hard drive was bad...a WD 40 gb.and she ordereed a Seagate 80 gb. which I was replacing for her. Running my WD Diagnostics Disk it reported the disk was fine..checking further, I ran Norton Anti-Virus and found 17 viruses on the disk, which she said she ran Norton nearly every day. At any rate, I reran Windows XP Disk on the WD drive (I lost part of info, but she said she could reload all of it) and found it to be stable and work very well--I also had run the XP Home Edition on the Seagate drive. Now, I have two hard drives C & E showing under my computer and in disk management as 0 and 1. When I reboot it gives me a choice of Windiws XP on the WD drive or Windows XP System on the Seagate. Am wondering if there is some wau I can access the files on the WD Drive while using the Seagate Drive OS - and visa versa .. or do I have to keep switching the drives depending on the info I need? I am sure there is a thread for this on here somewhere but have looked thru the threads without any luck. Any suggestions or a good clear "how to" site or just keep switching...the Dell bios don't give me much options to work with. At any rate, Thanks for Your time.
