Who here is using eSATA with OS X?

[M A V I C]

I just ran into a really odd issue and I'm not sure why. I have an esata enclosure. I ejected it (Finder.) I put a new drive in and started it back up. The Disk Utility refuses to recognize the new drive as anything but the old drive. Still reports it as a 1.5TB drive (same model and everything) even though it's a 2TB drive.

Anyone else tried this? I wonder if it's because it's a Hac.
