IIRC, the U2 family driver is different than the UW family. You need to install the appropriate drivers for the card to work.
I’m trying to think about what I did when I went from a UW card to a U2W card many moons ago. I don’t remember if I didn’t just reinstall windows from scratch. If you do want to reinstall windows, you need to use the util on adaptec’s site to make a driver disk and feed Windows the appropriate driver at the first stage of the install when you can manually specify drivers. You have to press one of the F keys, don’t remember which one, when the installer first starts to load in order to activate the manual driver install functionality.
If you’re trying to keep your existing windows, here’s a procedure to try:
-install both controllers into the PC. (you might need to temporarily remove other cards or disable some onboard devices to free up the IRQs to do this).
-boot with your drives connected to the old controller.
-let Windows detect your new controller and install the appropriate drivers.
-reboot, this time moving the drives to the new controller.
-if this works, shutdown, remove the old controller and put things back the way they’re supposed to be, then boot again and cross your fingers that it’s all good.
I hope this works for you
As for geometries, I've read that you cannot always go from one brand SCSI controller to another because of differences in the way they actually write to the drive. In fact, you might even need to low level format a drive that was previously used with another brand controller. I've not had any such problems when dealing with different families of Adaptec controllers, although I’ve never used the not Wide varieties. Good luck.
