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.
