Okay, so I downloaded Windows 8 Preview twice, once from my Bulgarian computer and once from my American NAS becasue the SHA1 Sum didn't match for the Bulgarian download. I redownloaded it twice from Bulgaria and both times it got the same SHA1 and MD5 sums. Ironically, I searched for the SHA1 sum on Google and two other people had this exact SHA1 sum. I'm looking for an explanation of this.
- Was one copy of Microsoft's iso in their CDN corrupted?
- Is the two byte change a logical change for a corruption?
- Is it something else, like an corruption from a 3rd party?
- How have 3 people gotten the same corrupted file?
- How did I get the same corrupted file 3 times in Bulgaria and the right one when I got it from the states?
The two posts seemed like they were not from an English speaking country, maybe Europe for both of them. They both also happened on March 1st, but I don't remember when mine was. I bet it was about that time because one of them hadn't been indexed by Google when I first ran into this problem. That would support the theory that one copy on the CDN being corrupted and it was just the nearest to the three of us.
Windows8-ConsumerPreview-64bit-English.iso SHA1 sums:
1288519c5035bcac83cbfa23a33038ccf5522749 from USA
bdb76fbdcadb570d9d1a7955c7dd582f7ff585c8 from Bulgaria
Here are the actual differing bits from vbindiff:
USA (good SHA1):
0C6E 76A0: 00 00 C2 02 00 00 00 00 00 01 00 01 00 00 00 F6 ........ ........
Bulgaria (bad SHA1):
0C6E 76A0: 00 00 C2 02 00 00 00 00 00 01 00 5E 02 00 00 F6 ........ ...^....
