is there a freebsd equivalent to scandisk and diskdefrag so that i can clean the drive it says on start up that the dir are fragmented but after that i am unsertain.
If there is "fragmentation", it is cleaned up in the boot process (for 4.x) or done in the background after booting (on 5.x).
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 there's ever a significant problem, you'll be told to boot single-user and fix it yourself using 'fsck'.
Or you didn't notice. Usually next boot will show you. If a hardware failure occur, you may never notice except you check your entire disk(s) and prove all sectors on the disk.
