    Verify downloaded iso files before burning?


    Hi Everyone,
    Would anyone know/recommend any software to verify integrity of downloaded iso files, ie checksum hash, before & after burning to CD-DVD?
    I'm a newb when it comes to this stuff. So any info or recommendations are most welcome.

    Thank you!

    Google for this:

    MD5_SHA-1 Utility.exe

    I've used it successfully, but can't remember where I got it.

    Here's one from Raymond Lin.
    His description and mini-tutorial on use:
    MD5 & SHA Checksum Utility | Raymond's WordPress

    Download it form download.com:
    MD5 & SHA Checksum Utility - Free download and software reviews - CNET Download.com

    I think your downloaded file will have to have a checksum to check it, I'm unsure.

    This is pretty handy, it adds a tab on the properties window,

    HashCheck Shell Extension

    This may be helpful info as well,

    Thanks for the response everyone.

    @ ignatzatsonic, was wondering if you where referring to the MS download or the one referred by Britton30?
    I saw a lot of others when I googled. :)

    @ Britton30, yes this one looks intriguing as it is stand alone-no install.

    @ derikimo, the HashCheck shell looks interesting as well. Open source stuff, kinda like the sounds of that.

    Would anyone know if there are any file size limitations to these progs to process say 3-4 GB images?
    Also, has anyone heard of or used a prog called HashTab?

    Thanks a bunch for your input.
    Cheers!

    I haven't used hashtab but it looks a lot like the hashcheck I use.

    That is a 3.09GB ISO I just scanned in the top screenshot.

    Hi derikimo,
    Would you have any estimate of how long it took to work the hash? just curious.
    Thanks,

    I use the HashCheck shell extension too, it's a nice a simple option.
    On my computer, a 4.7GB DVD image took around 2:30 minutes to compute the checksums, to give an idea (with the file on a SSD which dramatically increases the reading speed). I would expect other programs to have similar times too.

    Simple free tool that verifies MD5 and SHA checksums.

    Hi Alejandro85,
    Thanks for the input. Yes the two shell progs look very similar. I just tried HashTab on a 3.0 GB image on my SSD & it took about 45 secs. So I would think working a hash on my 7200 rpm (500 Mg cache) internal HDD would take about 2:00 mins about like yours. Just a guess. That is plenty fast enough for me.

    Cheers!
