That's why I mentioned laptop-mode-tools. If configured properly, it ensures that the drive will not spin up a few seconds after having stopped, by buffering all writes. For example, I have configured my laptop to buffer writes for up to 10 minutes. The drawback, obviously, is that I can loose up to 10 minutes of work if I have a power interruption, but on a laptop, this never happens. I'm not sure I would want to have that on a server, though. -- Remy --------------enig962BBD6F322B798EBF834F03 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) iEYEARECAAYFAkmN+7IACgkQCeNfIyhvXjKceACgkSfjJRdgnHqMvugX/MokxUil K+0AnAnamoOGkzhjrBGF/B6JYQtnLK7M =oNo3 -----END PGP SIGNATURE----- --------------enig962BBD6F322B798EBF834F03--
