I'm planning on upgrading the HD inside my MacBook C2D 2.0 from 80GB to 160GB. I have an old iMac DV SE 400 MHz for my kids with a 10GB HD in it (Ultra ATA). I am wondering if I would be able to use the 80GB HD from the Macbook to replace the current HD in the iMac?

If not, any recommendations for good drives for the older iMac? (120 GB or less in size)

Nope, I don't think a laptop drive is going in the iMac.

I'll leave recommendations to someone else.

The iMac uses a desktop parallel ATA. The MacBook uses a laptap serial ATA. It won't work at all.

Thanks for the clarification. I'll just put the laptop drive into a Firewire enclosure and attach it to the iMac without removing the iMac's HD. I guess that would be best, leaving the OS and applications on the iMac's small drive and using the new external for files and storage.

A new bigger Ultra-ATA 3.5" drive will likely be cheaper than an enclosure. Note that you can't use anything bigger than 128 gigs in that Mac, but 120 gig UATA are cheap by now. The enclosure is easier though, as installing an HD in that iMac is not exactly easy. Definitely doable if you're not too hamfingeredm but be patient. Remove the VGA cover, unscrew the bottom cover and unscrew the shield (the net-like thingy) and you can see the drive cage. Keep track of which screw goes where.

Getting the data off it first is easier: upgrade the MacBook first, you can copy the files to it using Firewire target disk mode.
