What I downloaded & what I burned aren't the same

Hi! I downloaded an iso of Fedora 20, and when I burned it with k3b it turns out that I'm a little short. It was supposed to be 4462, and I only got 4429. The second time I burned it I got 4404 instead of 4462. Is that a significant enouhg loss to not install it or should I try a different burner like xfburn? Or could it be in the download? Thanx for what ever info you can pass on. It will be greatly appreciated.

k3b has option to verify written data. Use it for verification.

Hi,

I would check using md5sum check sum to see if your download ISO is valid. This is the md5sum for Fedora 20 'b52130db4067e3e7acf621653abce7ec' You can get this same check sum from Fedora for the version to be tested/compared.
If that does not compare then I suggest to get a new download & check again. You should burn the ISO image at a slow rate, 4 has always been successful for my burner. Takes more time but insures a valid burnt image.

Hope this helps.

Boot the disk and you'll find the menu has an option to test the disk. This will verify the MD5sums for each file on the disk and report any problems.

I've never had a bad download, but then I live in the heart of a big city with the telephone exchange only a couple of miles away. I've very seldom had a bad burn, but I always take care to use minimum speed.

If your download is OK but you keep getting bad burns, the problems might be the disk or even the drive. I suspect writing to USB is more reliable than burning a disk.

Burn at slowest speeds possible. Use high quality disc's.
