Existing users, 
I kept having the same problem trying to download the ATTO 3.20 driver. ATTO tech support responded to my problem report as follows:
“Please make sure that you download the driver file using Internet Explorer,
Safari will corrupt the download. Also, make sure you are using Stuffit
8.02 or higher. The latest free version on the www.stuffit.com site is v9.”
Using Explorer, it worked, but with two catches:
1. Explorer returns the message that it does not recognize the file format. In that window, just click the “Download as…” button.
2. StuffIt Deluxe returns a similar message, but it will expand if drag/dropped onto StuffIt Expander.
Conclusions:
1. There’s something weird about Safari. I suspect it has to do with its highly proclaimed advanced security features, since it displays other anomalies not experienced with Explorer.
1. There’s something weird about the ATTO 3.20 driver file.
Anyway, with a little persistence, you should be able to download, expand and install the ATTO 3.20 driver file.

How to download successfully - Robert Welch
I do know that I could not get Safari to download the file and that I could with Explorer 5.2.3.I know that StuffIt Expander (version 9) fully expanded it. When I tried to expand it with StuffIt Deluxe, it failed to recognize the file format, but immediately up popped the StuffIt Expander window; dropping the compressed file into that window did the trick.
I agree that there must be something peculiar about the download file.
Looking at the ATTO web site, I have the clear impression that ATTO is driven by hard core techies unaware of those real world conveniences, .sit, .sitx and .sea.

This solution does not work (for me at least) on Mac OS X 10.3.5 running Internet Explorer 5.2.3 and Stuffit Expander 9.0. I checked the file from Terminal, changing my working directory to the location of the downloaded file "xulplus_320.tgz" and running the file command against it simply returns "data" as the file type. There is no recognition of it being an archive of any kind. I'm pretty confident it has nothing to do with Safari, at least for specific users. From my perspective, the problem is a corrupt archive file. Why don't they just zip it using Stuffit DropStuff 9.0?Reply to This
