Triggered by the off-list post, I've understood from sysutils/fusefs-ntfs/pkg-descr that ntfs doesn't preserve file ownerships and access rights. I'm afraid this is also true for fat32. If that is confirmed ntfs and fat32 are useless in combination with rsync(1), which leaves indeed only tar(1) and fat32|ntfs :-( With the permission of the author I have bounced the off-list reply. The list seems to have filtered it. So here it is: === Date: Thu, 18 Feb 2010 10:31:54 -0500 From: Lucas Holt <luke@foolishgames.com> Subject: Re: Incorrect super block To: Harald Weis <hawei@free.fr> Harald Weis wrote: >Has anybody encountered the following problem ? > >Mac OS X does recognize FreeBSD partitions on USB disks, but doesn't >want to mount them because ``Incorrect super block''. >This is extremely annoying for my ``client'' because he relies on dayly >backups on USB keys.

Apple has been moving away from UFS support in OS X for awhile; snow leopard is quite stale on this front. Luke === Thanks again. I'll report a.s.a.p. the outcome of the ufs1 experiment. Harald
