Post by Zenkaino lovelive »

I'm looking for the file "en_winnt_4.0_wks.iso". This file doesn't exist in FTP.

your iso is only overdumped (non iso byte padded) file size 605.606.172 Bytes
here are the valid dumped iso image data (Volume has 295661 blocks of 2048 bytes each) = 605.513.728 Bytes

This is already on FTP (more than once) - all releases include exact the same iso image

No. These files are not started as "A3A...". If exist, please let me know.

No, your mistake is, you compare apples with pears

let me explain:
- the valid size of a ISO 9660 image is defined by Ecma-119 (8.4 Primary Volume Descriptor )
- each Primary Volume Descriptor include 2 DWORD wich discribe the valid size of the iso
8.4.12 Logical Block Size (BP 129 to 132)
and
8.4.8 Volume Space Size (BP 81 to 88)

- Logical Block Size is typicaliy 2048 (bytes)
- Volume Space Size is the number of Logical Blocks in which the Volume Space of the volume is recorded (AKA sectors)
Logical Block Size * Volume Space Size = valid size of the ISO Image !!!!

as i already mentioned
here are the valid dumped iso image data (Volume has 295661 blocks of 2048 bytes each) = 605.513.728 Bytes
A3A8528C34FA8120CA6945320051052744A1C121 *en_winnt_4.0_wks_sp1_040bit_FPP_19961014.iso

you must be cut of all bytes behind 605.513.728 bytes to get a valid ISO 9660 !!!

similar all iso on BA are riped overdumped -> this is a general Mistake on BA and the whole WWW

how this overdump happen during Rip:
short answer:
similar all APP's
- rip the lead-in <- this is part of ISO 9660 image
- rip the data block <- this is part of ISO 9660 image
- and rip the lead-out (only in case no UDF Header present) <- this is NOT part of ISO 9660 image

-> result the riped (or converted) iso is only a file with the .iso extension but NOT a valid ISO 9660 image

In the Middle Ages all people believed, the earth is a slice. The few things knew were burned as heretic
So please no discussion or try to condemn me as heretic

/(Misc) Compilations/PC
/Microsoft MSDN (Green)/2001-01 - 0421.0 - Windows NT 4.0 Workstation\*.*
/Microsoft MSDN Development Platform/1997-01 - 04 - Windows NT 4.0 Workstation/*.*
/Microsoft MSDN Platform Archive/2000-01 - 02 - Windows NT 4.0 Workstation/*.*

are all overdumped !!
cut them of at 605.513.728 bytes and you get always a valid ISO 9660 image SHA1: A3A8528C34FA8120CA6945320051052744A1C121

Notice
file.iso <> ISO_9660.iso
make Always sure that your ISO also has the right size (is a valid ISO 9660 image), before you create and compare Hashes
