It failed after about 2 gb. I don't remember the error message now. I used ncftp and it appears to have downloaded all 4+ gb. I'm using ext3 on a 160 gb hard drive that has at least 140 gb available.
When you tried to download the large files via Mozilla what error message(s) did you receive when it failed ? Also, do you remember about how much of the file downloaded before it failed ? Also, what filesystem are you using ?
