If computer crashes, but hard disk still gets power from UPS or laptop batteries, hard disk can complete queued writes successfully. Enabled hard disk write cache is not necessarily the cause of your file system corruption. When your box crashes, and openGL/X-server/kernel-drm starts writing to kernel RAM locations they should not modify, then such crash may well cause serious file system damage. > Is this write cache turn off permanent?

On SUSE, maybe you can create new boot script: /etc/init.d/boot.d/S01myhdparm.sh > I suppose this change will reduce harddisk performance a little bit, right? Write performance will suffer badly. -- Jari Ruusu 1024R/3A220F51 5B 4B F9 BB D3 3F 52 E9 DB 1D EB E3 24 0E A9 DD - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
