backing up in a ext3 external drive

    I have just borrowed an external disk Maxtor one
    touch 250GB formatted with ext3 (from an linksys
    NSLU2 NAS). I would like to backup my laptop files
    and make a clean OSX install and then retrieve them

    Sorry for the type of my question. Can I trust the driver since it
    is an ext2 one? There is no problem writing and then
    reading it back right?

      ext3 is backwards compatible with ext2. When you mount with an "ext2 only" driver, the ext3 journal is simply ignored.

      The OS X driver is stable, and fully read/write compatible. Be aware though, there seems to be some problems with certain USB drives (read the USB threads in this forum), so if possible use Firewire.

      Yes I have seen the USB threads, that is why I am asking.
      I am planning to use the drive through firewire.

      There is no limitations of the type of files, length etc, right?

      thanks again!!!

        No limitations, other than device files probably won't work because OS X has a different device layout. As for length, files > 2GB are supported.

        USB works sometimes, but sometimes it doesn't -- it seems to depend on the specific hardware device. Firewire and IDE always work.
