Question about hashes...

Post by Iceman[grrrr] »

I was wondering... can 2 files with the same crc have two different ed2k hash ?? I guess the chances are very slim...

if not, then the crc in here is wrong and should be removed...

I have a file with that official crc and my ed2k hash is B49C6143A97EB3C218D9579823F48813 !

I'll add the file if that's the case...

From my understanding, no, they cannot be different for the same file. Which means the files are different.

Are the CRC's the same? If so, something bizarre is going on, or somebody made a mistake in the entry. If they are different, then that proves the files are different.

Yes. Unlikely, but possible.

*done* and asked the user who added it to re-check his CRC
I also removed the valid CRC from file 19281 with another wrong hash, which was already marked CRC invalid due to whichever reason...

(Same hash/crc here, so) please add the uncorrupted version ;)

I notice many case like this one (i'm new here and i'm uploading mylist right now).
I'm using AOM 0.2.2.80 to generate hash in batch: is this reliable?
