    Hi, My friend just gave me a copy of his 64 bit vista buisness DVD to re-install my OEM ultimate as 64 bit. As I understand vista disks contain all OEM/Retail versions.

    I was wondering how would I do a check to see if there has been nothing modified in the DVD like a hash check or something?

    MD5 Hash of vista x64 is

    11E2010D857FFFC47813295E6BE6D58D

    Which means it should be fine right?

    my x64 is 3,796,490,240 bytes

    Also it has the following Hash checks

    MD5

    11E2010D857FFFC47813295E6BE6D58D

    SHA1

    04671CE6713921983FF23AB9FC3E7A9280* 712B94

    CRC-32

    CE211A58

    After googling them numbers came up so it should be alright, right?

    Can operating system disc be comprimized

    Md5

    By the help of Imgburn software, create an iso of the disc, then use an win32 md5 hash program to make an md5 hash of the iso file.

    Because my friend gave it to me and I didn't want to use my quota, So it should be fine to install then and just update it to SP1 and stuff?

    What are a chances of a disk being comprimized and having the same Hash's

    Yes, it's quite easy to manipulate CRC32 hashes. For example, all the XP ISO files at MSDN have the same CRC32 hash (FFFFFFFF) and yet they are completely different.

    But I was referring to the SHA1 + CRC32 hashes. If these two are correct then it's impossible to have a compromised file (you can't fake both CRC32 and SHA1 at the same time).
