I don't have the original discs so I wanted to know if anyone knows correct sha1 checksums for iso's ripped from these discs. I still had my 2006 version of UltraISO and that migh be the year I last used this. I did use it alot back then and just getting some flashbacks when I see the settings or Windows volume labels. Like Windows Me, it had strange volume label and I remembered "oh yeah it was this" when I saw it. Anyway thank you I had forgotten that end byte thing. I mounted the iso in Windows and made new iso with enable iso volume filter checked and got a new checksum. So that's fixed but I would still like to know if there's anything funny with the files on the iso's.

Thank you. After removing the end byte I get same hashes than you did. But what's the source of your iso's? Did you rip those from original discs?
Ok so probably the same image then. It won’t rule out the fact that there is CIH virus in it. I had it in 1998-99 and I remember it came from Resident Evil 2 disc that I got from my friend
Are these images official? They're available on Archive.org Code: 1e0d5723761f2fd7e488326b87d7627710b32200 *WIN_XP_EMBEDDED\XPESP2A.ISO 027ae8164b3baca919af0c7bf8f3214cf3758b8c *WIN_XP_EMBEDDED\XPESP2B.ISO f0847f0be71f8712b76b8d4f99502c8ecadc53be *WIN_XP_EMBEDDED\ZWTISO.NFO

A little update/summarize. CRC 3.00/3.05/MSCDCRC will validate AutoCRC as valid also by subtracting: Sector 0 - 15 of ISO (16 sectors in total) - 0x0-0x8000, sector including first AutoCRC - 0x0-0x7E8 (2024 bytes in total), sector including second AutoCRC - 0x0-0x7E8 (2024 bytes in total) First AutoCRC is complement of 0x0 > including [41 75 74 6F 43 52 43 00] of ISO Second AutoCRC is complement of 0x0 > including [41 75 74 6F 43 52 43 00] of ISO I'm still missing ExclCRC based on above subtracted byte values, still not sure if ExclCRC is CRC-32 or complement of value. I can still make two images based on cdimage with different SHA-1 but identical AutoCRC - without modifing.

(total) AutoCRC is always the 2.nd AutoCRC = Datablock + Footer of the iso the calculation always start with crc32 = FFFF (coz 1.st AutoCRC) 1.st AutoCRC = lead in + Iso Header conclusion if AutoCRC of 2 Images are identical (and both valid) then only the Datablock + Footer identical iso header can differ !!!! (eg timestams differ or differend CDIMAGE settings)
Agree but... i was able to "modify" (by recreating with cdimage) the UUIDREF sector (before first AutoCRC) on a 2003 image a while ago and I could surprisingly still maintain same (both first and second AutoCRC) without modifing. (and by that i mean the complement) So i still ponder about the ExclCRC calculation.
UUIDREF sector has also a crc32 (last for byte of the UUIDREF sector) the total running crc32 at the end of the UUIDREF sector = FFFF all further calculation continue with FFFF -> 1. AutoCRC (and ExclCRC) never change independend of the content of UUIDREF value
I know but I've never considered this value as a complement. Iirc ExclCRC differed, but AutoCRC complement was unchanged in my case. (since my focus has at this point been at the AutoCRC) Interesting...
Does it still possible to find/dl such this All-In-One image Windows XP English with Service Pack 2/2b Select Edition CD 17in1 ?
Images from Egorz. He is a member of the ru-board forum. Access to Russian websites is blocked in our country. I'll check the old HDD later, maybe I have some of its images saved. But this is not accurate. Yes, it will take a long time (power outages, Internet outages, air alarms..) Images of "home production", if I find them, I will drop them in a private message.
