Windows 10, Mega Pack 1136, Wrong MKV file creation date

Post by xqwzets on Sat Aug 22, 2015 5:58 am

I've just upgraded my system to windows 10 (clean install) and it looks like some of my MKV files display wrong file creation date. Even when I download new file from the internet - it sometimes is wrong and sometimes is right.
I guess file is ok, but windows cannot read it.. for some reason from some of the MKV files..?

The creation date is stored as an integer value. The value equals the amount of 100 nanoseconds units since 01-01-1970 00:00 UTC.

So those few files have a value of 0. The most logical explanation is that the creator(s) of those files have intentionally set it to 0 to hide the real creation date/time.

The same files had real creation dates when viewed on windows 7.
Also MediaInfo displays real date like this
Encoded date: UTC 2010-02-22 21:41:29
or it maybe actually this:
_STATISTICS_WRITING_DATE_UT : 1970-01-01 00:00:00

I'm not sure. Either real creation date cannot be read from those files OR those files got corrupted upon being viewed on windows 10.

Explorer normally only shows generic filetime values. But maybe they changed something in Windows 10. The encoded date and statistics date values that MediaInfo shows are metadata values specific to the Matroska container.

It looks like it's not your fault. I did few more tests and it seems that the date gets corruped only when I put/download MKV file on my raid0 drive using win10.
Downloading using win7 does not corrupt file date.
Downloading other files than MKV does not corrupt file date.
Downloading to any other drive does not corrupt file date.

It's wierd as fuck. Sorry for those baseless acusations, I guess microsoft did somethink wrong not you.
