Decent write caching on IDE devices can eat your whole file system.
Turn it off (I have no idea of internals, but I presume it'll still be a write-through cache, so reading back will still be served from the buffer). Do hdparm -W0 /dev/hd[a-h].
One might consider adding TCQ to the IDE driver. FreeBSD already has it, and IBM drives talk it. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
