In that case it would mount the=20 device in which you saved your settings, but this would be something the us= er=20 would set up and run consciously at boot time. > One thing I'm fairly sure on, though, is that without the > "-f" flag, mount won't take the risk on an unclean NTFS, and instead > just tosses an "are you sure?" message, which would make me presume > even those livecds that do look for extensions wouldn't risk the > damage there. =46rom what I recall the Linux kernel NTFS driver will mount a unclean NTFS= =20 partition regardless (can't recall for sure though), but the ntfs-3g will=20 behave as you describe above. So in answer to the OP questions, the only way I can think that a Linux Liv= eCD=20 would corrupt a NTFS partition is to mount it with the Linux Kernel driver = as=20 rw and then create or edit a file. If this was not the case and fs corruption ensued, then it would be just a= =20 coincidence that the drive had some bad blocks and they decided to play up = at=20 the time the MSWindows fs was being booted into. =2D-=20 Regards, Mick --nextPart5067562.5F0pcIVR3v Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (GNU/Linux) iEYEABECAAYFAk4TANUACgkQVTDTR3kpaLYHlQCg9/QnozKOscj1lZ8DJY50ERfv W0YAoM5Syx09WYEwansAK/oLrapmNWdY =MRJg -----END PGP SIGNATURE----- --nextPart5067562.5F0pcIVR3v--
