Have tried using every browser (chrome, firefox, safari, ie, opera) to download wetland data from: wetland data download with no luck. It either chokes around 400 MB or finishes up with a corrupted zip file which cannot be opened. It is only an issue with the larger .gdb files (over 400 MB), like Texas which is 1.7 GB.

Any ideas on how to download these files without error?

Have you tried a download manager? – Jason Apr 11 '12 at 18:42
I had the same problem. It always failed on my slower work connection, but succeeded on first try at my faster home connection. I can only guess that their server times out if a download takes too long. – Scro Apr 11 '12 at 18:58
email '' there server is timing out with users sessions. – Mapperz Apr 11 '12 at 21:02
Jason's download manager suggestion worked. I found GetGo… to work the best after trying several of them. – sirgeo Apr 18 '12 at 20:57
@sirgeo You might want to post that as a solution to your problem and accept it. That way, others would know that the issue has been resolved. – R.K. Dec 21 '12 at 8:17

It sounds like @Jason had the right idea by suggesting the use of a download manager. It's likely that the server has a limitation on bandwidth per connection, which is circumvented by a download manager's ability to perform multiple simultaneous connections through a multipart download.

The download manager will also be able to deal with interruptions in the connection by pausing and resuming once the connection is reestablished, which would help if the issue is server timeout.
