hi
when i download DVD image in windows ,always md5 of images are incorrect.
what is problem? windows file system? windows OS ? Download manager? iso image? ......

thanks for your help

Large images are prone to corruption during downloading. Why dont you try purchasing DVDs?
Or else download the images on some box with a faster connection.

This is a bit strange.
Maybe you could use wget for windows
or just get the debian windows installer : http://goodbye-microsoft.com/

The FAT filesystem can't handle files larger then 4 GB. If you're on Win 2000, ME or older, you're on FAT. NT and XP (and Vi$ta) use NTFS that can handle >4 GB files.

An expert opinion.
thanks for the information.

You can also try using jigdo for Windows which allows you to switch mirrors on the fly if your looking for the fastest one, allows you to shut down at any time and resume at a later date, and checks the final md5sum etc. to make sure it's good. If you have an old DVD, some of the packages may be used from it to avoid downloading them if they are required by the template.
Torrent downloads are also checked when the download is complete to make sure it is good, if you get a "successful", it's good.

i was download images in NTFS partition. and my connection very fast (18 Mbps).
I must test wget and jidjo for windows

thanks a lot for your help

Was the file size correct and just the md5 wrong? Or was the file size also wrong.

Every time I tried to download a dvd .iso file to windows by ftp or http the final size was always way low. I only got it right when I used bit torrent instead of ftp or http.

And I am wondering if with downloading it with knoppix live cd would work, linux is more powerful than windows.

you can use knoppix on one machine, and mount a windows share and use knoppix to copy it to windows

I wonder if knoppix live cd would have enough RAM for that operation

Seems like a drastic and difficult solution. Isn't there a torrent available for the .iso you want?

Reasons for failed downloads include
- using Internet Explorer, which has been known to produce corruption in larger isos; use firefox instead
- corrupt RAM; recurrent failing md5sums are often an indication of bad RAM - use memtest to check your RAM
- limited file system (as pointed out by Dutch Master)

Anyway, if you seem to be fine with downloading a whole DVD, why not download just the first cd or the netinstall disk? Downloading the DVD means you waste 4GB with each download.
Of course, if your problems are hardware related, this is not a proper solution as the problem is bound to resurface sooner or later.

I have also seen defective windows md5 hashing programs that gave bad results all the time (no clue why), when a different program was used to check the md5 it showed as correct, and when the image was burned it worked just fine.. Weird experience really..


Either way I would just download the netinstall.iso (150 MB) it's faster and easier than downloading a huge outdated DVD iso.. imho

a md5 is a md5
use win32 totalcmmder to check it
F3, F4

& dont burn, use daemon tools first to check it

i test md5 in linux and didnt any problem with this one

i didnt have time yet too test wget in windows for DL
