Did it changed? My last information is, *bsd checks the disks at boot if they were not cleanly unmounted. Otherwise there will nothing happens in this direction. > Note that "fragmentation" on a ufs volume > is different from what you're used to > on DOS/FAT filesystems. Yes, fragments are parts of a block of a filesystem, where several small files or tails of files are stored together to avoid waste of space by using an entire block for a small piece of data. > As long as the box is running, you have no > worries.

If a hardware failure occur, you may never notice except you check your entire disk(s) and prove all sectors on the disk. Jens
