You might want to turn off soft-updates because they rely more on the hard drive cache correctly behaving than the alternative (the "normal" mode, without sync or async). If you do so, file system operations will be slower and you will suffer long fsck times, but at least your file system will be consistent (which says nothing about your data). --------------enigBFE08B92D7B118335E173334 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.4 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGEqZhldnAQVacBcgRAhoFAJ47QTWFhugC4SULAyCquBRBQZH1pgCg0pTI 4PsYZ2mf1N+T15erFWuOJ9Y= =aMG2 -----END PGP SIGNATURE----- --------------enigBFE08B92D7B118335E173334--
