AutoCRC is a simple crc32 hash but it is more ore less a doubble CRC32 (hash from a hash-value) we have 2 AutoCRC inside a iso 1. is insertet after last ISO-Header sector (end of header) -> CRC32 is always FFFFFFFF at this point 2. is insertet after the last ISO-Data sector (end of iso) -> CRC32 is always FFFFFFFF at this point hash from a hash-value ExclCRC <- CRC32 hash (from what is current unknown) AutoCRC < CRC32 Hash from hash (Incl. ExclCRC and the string 'AutoCRC' ) if you change a byte in the ISO-Header -> first AutoCRC change -> and CRC32 is also FFFFFFFF at this point -> 2. AutoCRC do not change (because it is a CRC32 for the DATA Block - Start value for DATA block is FFFFFFFF) if you change a byte in the ISO-DATA Block-> first AutoCRC do not change -> and CRC32 is FFFFFFFF at this point as usual -> 2. AutoCRC change -> and CRC32 is FFFFFFFF at this point as usual NOTE AutoCRC indicates the media in X:\ is VALID VALID missleads to Valid MS should be better interpreted as AutoCRC indicates the media in X:\ is NOT Defect and has a valid ISO size NOTE 2: each iso that have a UDF Header iside - is not overdumped - have no AutoCRC coz the UDF rules However MS try to integreate AutoCRC without hurt the UDF rules there are some rare DVD isos inside the MSDN with UDF header+ AutoCRC (only the 2. AutoCRC was integreated inside the 'UDF Backup' sector at the end of the iso) dont ask me wich iso (i cant remember) dont be surprised if you stumbled over such an iso
When almost nobody knew how to use CDIMAGE, we could trust ISOs created with CDIMAGE that included AutoCRC. The problem is that people started using CDIMAGE to recreate their own ISOs and now we can no longer trust that an ISO with AutoCRC is genuine. Take the Windows 2000 SP2 PT-PT ISO as an example: it has AutoCRC, but if you compare it with his English ISO counterpart, it was created with an older version and older date. Do you believe Microsoft would release a PT-PT CD almost an year before an EN-US CD? So unless we have an original CD to verify, we must assume someone remastered it with an older CDIMAGE and different date. People used to say the Sun orbited the Earth, now they say it's the Earth that orbits the Sun. Opinions change when the facts change, and so do we.
I have several versions of Windows 2000 SP2 created with CDIMAGE 2.39 or 2.27, all false? yet they have all been published here. The only real unknown is the date of the files ... but what I wonder is ... why create a "perfect" ISO and only make a mistake in the Timestamp ?! so most of the SHA1 posted in this forum are fake ... following your reasoning.
Anyone can create an ISO with CDIMAGE and AutoCRC. Microsoft is known for not being inconsistent with timestamps and/or CDIMAGE versions, so unless we/you have original CDs or SHA1 hashes from MSDN to verify the ISOs, no ISO is trustworthy, all we can do is assume they might be untouched using several checks, two of them being AutoCRC and timestamps. When one of this seems "off", ISOs might look remastered even when they are untouched. That's YOUR reasoning, not mine. All I said is that facts change, one of them being AutoCRC is no longer trustworthy, due to the fact anyone can create ISOs with AutoCRC. Here's an example: I could be the only person in this forum with several Windows 2000 SP2 PT-PT original CDs, I could rip them all, remaster them with a different CDIMAGE version and/or timestamp (maybe because I think a different date wold make more sense? or because they had different dates and I want them all with the same date?), share them, and if nobody had another set of originals to confirm, everyone would accept them as the originals. If you want to discuss this even further go ahead, I'm done with it, I don't like running around my own tail.
Are there any windows 2000 pro/server editions in spanish with sha1, but from real msdn/microsoft images? not homemade with ultraiso/poweriso.. etc main post link is deleted or where can I find them... thanks any help guys!
Have you checked the 2 ISOs in Winworldpc? They have Windows 2000 Professional with SP4 and Windows 2000 Server with SP4, just open with an hexeditor and search for "AutoCRC", if they have it they are probably untouched, just make sure you delete the zeros (extra padding) after the 2nd autoCRC entry close to the end of the file, in case they have it.

yes, they are fake, also with archive.org. ------------------------------------------------------------- what about win 2000 pro/server spanish with SP4, vanelle? thanks for the info.
what should I do and how? I never did that padding thing. and about the SP4, i mean the ISOs not the files (exe).

SmartVersion | Tools + Scripts Use the image you dl as source for the attached svf file. Regarding SP4, is what we have/know for certain. Will update if something surface, maybe community members have something too.

We don’t have to always struggle with a problem. You can choose to trust all the valid information he provides, or you can deny everything.
The thread is called "Microsoft Windows 2000/XP Info for Collectors". I'm guessing collectors are not interested in homemade ISOs, so it should be obvious that unless the ISO has an online source like MSDN where the SHA1 hashes can be verified, the only way to confirm that a posted link comes from a real CD/DVD, is adding a photo of the physical media it came from. The photo will only prove you have the media, we will have to trust the link you posted comes from that media without any modification. There are no rules to this thread other than common sense. If you want to share info/links you have from physical media you own, fine by me. If you want to add a scanned image from each CD/DVD for each ISO, even better. If you don't have a scanner but can take a photo from the media with a cellphone, fine by me too. If you want to argue what common sense is, you're in the wrong thread.
