So Many Versions

Thank you for the replies. FreeBSD version of fsck is a bit diffrent than that of Linux of other *nxs.
I have found a site that says try the...
# fsck -F ufs -o /dev/ad0s1e
option but FreeBSD does not use the switches -F or -o all i get is
fsck: illegal option -- F
fsck: ? option?

I will try and use all the alt super blocks option. That might do some good. Also I read last night that i might beable to extract the data of the disk buy using..

# dd if=/dev/ad0s1e of=test2 bs=2k

Has anyone used this with FreeBSD and does it work? I do not know the right use of dd.

I also found a place that said to use this to fix the disk...
# newfs -o b=32 /dev/ad0s1e
But with that I get this...

newfs: ime: unknown optimization preference: use `space' or `time'.

So I am still at a loss. Thank you.

NAME
copyfs-mount - mounts a versioned file system SYNOPSIS
copyfs-mount version-directory mount-point DESCRIPTION
This script lets you mount a CopyFS file system. version-directory is the directory where the files and version information will be stored by CopyFS. When using CopyFS for the first time, copyfs-mount will create the required files in the version-directory before running copyfs-daemon. mount-point is the directory where the copyfs file system will be mounted. This is where the users will have access to the files. If you want to mount a CopyFS at '/mnt/fs', whose version directory is at /var/versions, you would use: root@host# copyfs-mount /var/versions /mnt/fs To unmount it, simply do: root@host# umount /mnt/fs As you would do for any other filesystem. You can also allow an ordinary non-root users to mount and unmount CopyFS filesystems provided that the user is added to the 'fuse' group. Ordinary users will be able unmount the filesystem, using the fusermount command: $ fusermount -u mount-point AUTHORS
CopyFS was created by Thomas Joubert and Nicolas Vigier <boklm@mars-attacks.org> LINKS
