That's correct, however ext3 is backwards compatible, so you can read write an 
ext3 partition(it feels like an ext2 one), however - if you perform write 
tasks, then it will have to rebuild the journal on next real use of ext3
(probably when you start Linux again).

Not quite... ext3 can use some attrributes and features that ext2 doesn't 
understand. An ext3 filesystem making use of those can not be mounted as 
ext2.


AFAIK, it's not only the journal. But I don't remember where I read that.

Ext3 shares all disk implementation with the ext2 filesystem, and adds
transactions capabilities to ext2.  Journaling is done by the Journaling Block
Device layer.

This is from /usr/src/linux/Documentation/filesystems/ext3.txt

I think it was a design criterion of ext3, that it should be fully usable on 
an ext2 only system

I believe they are departing from that in ext4, to be able to be usable at all 
on larger file systems

Not quite. Any ext2 is mountable as ext3, and normally the contrary is 
also true. However, ext3 can add extra fields that are incompatible with 
ext2, so that a partition using those new features is no longer mountable 
by a system only capable of ext2.


This is true; however, I don't remember a document I can point you to.

Re: [opensuse] format external harddisk to ntfs

2007-12-07 Thread Greg Freemyer
 NTFS is one tool for doing that, but not one which
 will also allow reading/writing by Linux.  In fact,
 I don't think there is even a way to make an NTFS
 filesystem in Linux (other then 3G, which is not
 yet reliable enough to use).


ntfs-3g in r/w mode is a supported and default solution in 10.3.  I've
heard nothing about any problems with it since 10.3 was released.

For people storing big files on an external drive Fat32 is unfortunately
pretty useless. I use for that matter ext2, which can be mounted on
windows. According to my experience it's less risky than accessing NTFS
on Linux.

Don't these devices already come formatted for peecee? Is there any
reason you can't use fat32?

Every one I've bought comes with windoze fat32 format, and I've done the
opposite, and reformatted as reiser, since I have no need for windoze to
ever read the disk, and I want full unix semantics for my backups.

If for some reason you need it to be ntfs, and not fat32, you could
always let windoze format it.
