-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------- Original Message -------- Subject: Re: What are the dangers of leaving my external USB drive mounted? Date: Mon, 31 Jan 2005 23:13:00 +0000 From: Jon Masters <jonathan at jonmasters.org> Organization: World Organi[sz]ation Of Broken Dreams To: David Kramer <david at thekramers.net> References: <Pine.LNX.4.58.0501311710040.25340 at uni.thekramers.net> David Kramer wrote: | I am contemplating either leaving the drive on and just mounting it when I | need it, or leaving it mounted.

You run the risk of minor filesystem corruption if the power fails at the wrong moment and the UPS either doesn't kick in or is flat. Since a modern Linux system runs kernel flushing daemon that writes changed on disk pages out every 10 seconds, actual data loss shouldn't be too bad. I might also mention that it is trivial to add a journal to an ext2 filesystem and remount it as ext3, even just on occasion - please see tune2fs(8) for further information. Check that your machine is configured to actually shutdown on POWERFAIL. | PS- I am contemplating leaving it mounted because mounting it in a script | is a little hard. This is SuSE 9.0, so I'm not guaranteed it will always | come out as the same device name. Hmmm. That's using udev - I'll have a think.
