ATA Support is still under development.No complex software can be proved correct. This release passes all my tests,but there seems to be bugs left.YOU HAVE BEEN WARNED.If you use this software, it's at your own risk.Additionally, 1.0RC4 hasn't been stress-tested yet. It might fix a data corruption bug found in RC3.See the website for news:http://www.kallisys.com/newton/ata/
