Assuming you are using Windows.
Check the integrity of you ISO file with this free download
http://www.winmd5.com/download/winmd5free.zipInstall the application and check. The number it returns should match MD5:
7f4ebe2718ea9dc2f8051ee911fc63c9 (The same MD5 number on the
Downloads page.)
If you're using some version of Linux, or your copy of Navigatrix 0.4, you should be able to check the md5checksum from a terminal with
md5sum /location/of/the/navigatrix.iso <enter>That is the first step.
If it matches; remake the USB with the ISO; switching to another stick if necessary. If it doesn't match, the file was corrupted during download and cannot be salvaged.
48 hours to download the ISO works out to be an average of 12.54kB/s. It's a good speed for a backwater locale; it's not blistering speed, but not really bandwidth busting either.
Yes, it is a large file. This is one of the reasons
Make A Copy For A Friend function is prominently placed on the Desktop. You are able to provide a service for your fellow sailors. If some continue to give you grief, tell them they could wait until you're finished to download their
mandatory security updates and porn....on second thought they wouldn't understand.
Another option is to download via the
Torrent network. It won't be faster but has some error checking protocols and can be stopped (paused) during "the morning and evening rush hour traffic" and re-started at slack times. This way everybody is happy.
Is the Asus the 1015 series or the 1215 series? Is this the boat computer?
