You can get ext2 for macosx. It's a unix but not a linux machine, and ext2 is of linux origin :)
I think http://sourceforge.net/projects/ext2fsx/ is the one to use, it's been a while. Backwards and forward compatible with ext3, but it won't be journaled while mounted. You could have an ext2 image that's stored on the usb disk - or, actually, just keep the tarfile on the usb disk.. Also see 'man mount'. You might be able to do something like 'mount … -o umask=XXX dmask=YYY fmask=ZZZ' where X,Y,Z are masks to use. I don't think it is setting the permissions to 700, it's just not preserving or storing any permissions -s On 11 Set 2007, at 08:55, Graham Petley wrote: > When I untar a file onto a USB disk which has been formatted with > FAT, all the > file permissions are 700.
