hdparm's -W1 flag turns on the hard drive's write-cacheing, which speeds
things up, but makes unclean power downs more dangerous. Does anyone know
how XFS will handle such an event? While on the ReiserFS mailing list
awhile back, I was under the impression that this could do wonderful
damage to the filesystem, although I don't know how things are now. But
then XFS seems to be infinitely more stable than ReiserFS, and the on-disk
format is much more mature, so maybe (I hope) it handles things
differently.
Also, would anyone know how to force the drive to flush its write-cache
onto disk, like sync makes linux flush its buffers?
