There is a test in /etc/rc.d/init.d/mandrake_everytime whose task is to distinguish IDE drives candidates for hdparm optimisation, that fails to eliminate my IDE zip drive. And at each boot i got a 'hdd optimisation failure'. How to get rid of this ? Here is the test : if [ -x /sbin/hdparm ];then LIST_HD=$(grep '^hd.:' /var/log/dmesg|\ grep -ivE '(CD.*ROM|DVD.*ROM|FLOPPY|TAPE|STATUS)'|cut -d: -f1|sort|uniq) And here the line relative to the ZIP drive : Aug 8 02:17:52 agathe kernel: hdd: IOMEGA ZIP 100 ATAPI Floppy, ATAPI FLOPPY drive -- Guillaume Rousse Iremia - Université de la Réunion Plus petites unités de mesure - de longueur : le millimètre - de volume : le millilitre - d'intelligence : le militaire
