Ok, so I have downloaded windows 7, it says untouched. Here is what I found that the HASH info should be. Windows 7 Ultimate Retail English (x64) Name: 7600.16385.090713-1255_x64fre_client_en-us_Retail_Ultimate-GRMCULXFRER_EN_DVD.iso Size: 3224686592 bytes Date Modified: Tuesday, July 14, 2009, 17:40:25 PM CRC: 1F1257CA MD5: F43D22E4FB07BF617D573ACD8785C028 SHA-1: 326327CC2FF9F05379F5058C41BE6BC5E004BAA7 Now here is my problem, ALL of my info matches that EXCEPT date modified, mine says modified on. Friday, July 24, 2009, 9:42:30 PM Does that matter? CRC, MD5 and SHA-1 all match so im not sure. Edit: File size matches also, the date modified is the only thing at all that I can tell is different.
Thanks, I wasnt sure because isnt it weird for the date modified to not be the same? How can it be modified at a later date and all hash and everything still match!
Yeah, it's bit weird, but - you know - it works very well for me, too. I've the same infos for my ISO. Hashes matches & modified date is like yours: Friday, July 24, 2009, 9:42:30 PM I don't have any problem at all. So, have a lot of fun with Win7!
This is because date of creation/modification isn't part of the file, it is part of the file system (NTFS, FAT, etc.). Sometime even if you just copy the file to another location on the hard drive, the date of modification changes, but the file is still the same, the hashes are here to prove it
The last time I got a 14/7 windows 7 iso was from Liza from *****-bb. Shouldn't be much of a problem since the hash matches.
I thought that only counted for the creation date, I thought modification date never changed unless something in the file was changed.
Maybe, but think of it this way: even if you make a modification to the file (let say, you remove 1 bit) and then you undo this modification (i.e. put back the removed bit), the resulting file would still be the same as the original, right? Only the modification date will be different. The date doesn't matter. You can create the exact same file at separate moments. More simple, let say I create a string: Code: 1234abcd Okay, I have my 8 characters long string, its MD5 hash is: ef73781effc5774100f87fe2f437a435 And the creation/modification date is: Monday, 30 November 6:54:47 p.m.(GMT + 0:00) Now let say I edit the string: Code: 234abc The content is different, so its hash is different as well: e2cf7fc1ec4decc1c60efd26d8ae5a42 Let's edit the string again: Code: 1234abcd This is now the same as the original, but the modification date is different: Monday, 30 November 6:58:08 p.m.(GMT + 0:00) But the hash is the same as the original one: ef73781effc5774100f87fe2f437a435 because the CONTENT of the string is exactly the same, no matter when it was made the same.
So, someone probably change the ei.cfg or deleted it and then restored it. The hash matched so people everywhere downloaded it.
Ok well I just wantd to make sure I am not gonna have a virus or anything in it, I have legit keys I just needed a copy of the ISO, looks like I will be using this.
