Argh! Thank you for persisting with this. I have now looked at the
code and you are right it does not do the same thing. This is because
when Yura ported my $LogFile code from the kernel for some unknown to me
(or forgotten by me) reason he did not integrate clearing the journal
into the mount process. He integrated the checking but not the
clearing. This is a HUGE and VERY BAD bug in libntfs and means that all
ntfs utilities are _DANGEROUS_ to run and can cause massive and very
hard to detect data corruption. )-:
No wonder Vista does not boot!!! It is amazing it took so long to find
this problem. I cannot believe we managed to get away with it for so
long...
I have now fixed this in CVS. Could you update, compile, and try again?
Once just with ntfsresize (the one in current CVS) and if that still
does not work, once with ntfsresize + immediate ntfsfix (the one in
current CVS without the my change that you put in). If that still does
not fix it then once with ntfsresize + immediate ntfsfix (the one in
current CVS but with my change that you put in again).
In an ideal world, just ntfsresize will now be sufficient. If not
ntfsfix should work first time. And if not I need to look at it
further!
Thanks!
Best regards,
Anton
