My intuition is that a bogus script is going through and deleting things. ext2 is a very, very well tested filesystem. And I'm not able to think of a failure mode that would unlink all normal files.

But I have heard of problems, where even if the filesystem is extremely well tested and effective, that the hard drive itself caches data. Then the OS is helpless.


I have had similar bad experiences with the UFS+softupdates filesystem that comes with BSD, which I am sure is caused by hard drive cache that the software cannot flush.


Anyway, with ext2, cannot it be operated in either sync or async mode, and async is much faster, but much less forgiving of hardware failures?
