copy file issue

I went to back up my win 2000 partition today and only 2.5 gig out of 8 gig copied. I opened the drive in my computer used select all and copy.I installed a new sata hd for vista and dula boot works well. however my w2k partition was too small, so I wanted to back it up prior to extending it by deleting the data partion next to it.Fortunately there were no problems with extending the partition as I went ahead despite the partial backup. I had software for windows xp to create an image but that didn't work and the uninstall on that hung the computer with 100% cpu until I logged out and rebooted to shut that down. My tax software from the Australian Government doesn't work on vista so I'll have to keep the W2k going in the meantime.
