Is the new drive on the same partition the old drive used? 
Was GRUB refreshed? 

Do you have this new drive on its own controller that you can control 
it's own Bios settings?
Is the boot order correct in the bios?

I boot from /dev/hde1 as well and had to override the onboard IDE 
controllers and make the 3rd IDE the master controller.

The active flag I think is only used by DOS boots. 
I don't think Linux pays attention to that setting.
In the past, I've booted disks that never had it set.
