My guess is that it is more complex than that.
Some filesystems have issues if the raw drive is read while the filesystem is mounted. I think it is caused by inconsistencies in the various cache's. ie. iirc, At least in the 2.4 kernel there was not a single unified cache for block layer and filesystems. So doing raw reads of underlying device while it was mounted could cause the caches to get out of sync.
Oh, that issue? well, in that case, I have no prevent such thing...I was offering the previous idea since I have very little cues on what Prasad mean by "disabling access".... -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
