disk write cache

Maybe enabling the write cache is not such a great idea after all...Windows:"By enabling write caching, file system corruption and/or data losscould occur if the machine experiences a power, device or systemfailure and cannot be shutdown properly."Linux:"Write back cache on disks or controllers generated file system errorsthat rendered the file systems either corrupted or inconsistent. Manytimes, the file systems can no longer be mounted. We find that theproblems appear faster (typically fewer than 10 power cycles) whencache is bigger, such as when there is also write-back cache on theRAID controllers. Typically, we observed problems within 50 powercycles." disable write cache)Thoughts, anyone?Personally I'd rather have a slower, more reliable drive than have afast drive that needs frequent data restores...Michael
