I'm having an issue with the debian6-13-04-2012.zip file when I un-zip it the only file there is debian6-13-04-2012.img.sha1 so Win32DiskImager wont recognise the file do I just need to delete the .sha1 or am I missing some thing?
I'm just using windows to see that there is no file but Win32DiskImager can't see a file either I tried unzipping it with winzip and winrar both with the same results.
A .sha1 file only contains the checksum to check if the image is correct.
It seems you either have a corrupt or a truncated .zip file. The latter sometimes happens when the site you are getting it from is overloaded, and "stutters".
However, in such cases the downloaded file is normally smaller than it should be.
