I just downloaded the Mandrake Linux 8.1 iso files (3 648 MB files), using IE6, from the ftp server in New Mexico listed on Mandrake.com. I ran the md5 checksum app, and there were no errors. I figure if there would be errors, they would've happened during that like 15 hour download.
I'm downloading another 3 iso's of Slackware tonight. I don't expect any errors, but will run the crc check anyways.
In case you're wondering, I wanna check out Linux, and I'm about to move away from this house and DSL connection, so I'm downloading while I can.
