The power company has dropped power on me several times in the last few years, the heaters popped the fuse a few times (some dimwit wired the two main rooms to the same 20A circuit breaker), fiddling with graphics drivers and whatnot caused a few hardlocks which are easiest to recover from with the power button - plenty of non-existant shutdowns. I've used reiserfs on at least / and /home on all systems for uhm 5-7 years now and the recovery rate is 100%. The bootup-fsck fixes it for me (that's the reason one uses journalling filesystems). Ext3 back then wasn't really available (yes ext3 was a latecomer) and ext2 is unsuitable for anything much larger than a gigabyte if you don't want to die of old age during fsck, there wasn't that much choice actually. I remember fixing one bad superblock with fsck but don't recall which filesystem, I was using ext2 as well as reiser for some time, nor do I remember whether the cause was a disk failure. > Just one 'bad superblock' experience (under Gentoo at the time) was > enough to put me off for life. :) Most of the time this should easily fixed by specifying one of the backup-superblocks with fsck, unless the root cause is a disk failure (in which case you have other problems). I happily tell Windozers that under Linux, a sudden power-off will not lose you any files except for some of the content of those files being written to at power-off. The filesystem structure should always remain consistent with a journalling filesystem no matter what, because that's the point. Just last week someone was quizzing me "I copied a large number of files and in the gigabytes in a single operation from one ntfs partition to another; the operation failed and although some of the copied files showed full size, they in fact contained only zeros" (the person is computer-capable). I replied that I luckily couldn't comment on NTFS and that my multi-years experience tells me that this doesn't happen with Linux...
