the .snap is your snapshot directory dump uses to store a live file system before dumping it. it dumps the snapshot.

try gpart list, and read what it says. if it's properly partition and formatted. fire up a basic file manager and do the rest.

if it didn't mount, try phishfrys suggestion with the appropriate slice included.

My belief is that ada1s1a is a system partition or unused.
ada1s1b may contain your files.

So unmount 'a' and try this:
umount /mnt
mount /dev/ada1s1b /mnt
 
Unless they'd like to be promoted to Colonel Data Corruption; I wouldn't touch a running system drive. I thought the objective was to dump ada1 to ada0, then boot from ada0.
 
I sure don't see the advantage of an empty 928GB 'a' partition and a 3.5TB 'b' partition.
On new drive I would correct that.
Small system partition and rest OS.
 
There's a file system been placed directly on ada0. See the posting from Today at 11:26 AM.

hbsd, you need to stop taking little bits of advice from all quarters, sit down, and make a written plan to:
  1. decide on the partition method;
  2. create the partitions and file systems on the SSD;
  3. install the required boot block(s) on the SSD;
  4. copy some data to your external drive;
  5. copy the remaining data to your SSD;
  6. modify /etc/fstab on the SSD to reflect the new boot device;
  7. modify the BIOS boot order.
When you have a plan for all that, bring it back for comment before you take any more actions...

I have provided most of the references you need to read and understand in my last posting.

There is already a very nice instruction here on the forum how to do this. It's from Vigole and I put this to a test a while
ago. I wanted to move a FreeBSD UFS installation to a new computer and it works very good.

Here the link: https://forums.freebsd.org/threads/...oot-from-it-if-my-current-system-fails.76474/

Just follow the instructions from vigole it's the second entry and backup your current system. When done put the new ssd in and install a new system as normal. When done make a copy of /etc/fstab
and than restore your data and settings to the new ssd. Takes a while but it's easy to do.
When done restore the /etc/fstab file. Reboot and all should be good and much faster on the ssd.

I really don't know how to thank you guys. Once again, I will do the steps from the beginning and read each and every comment of this post again and I'll inform the result. Sorry to bother, my friends....
 
I finally mounted SSD with mbr file system! I used Absolute FreeBSD, 3rd Edition: The Complete Guide to FreeBSD book to do this. It's a amazing book. In other words, it's like the newer FreeBSD handbook. as you can ada0 is my ssd drive. I will transfer the files to SSD later. Thank you so much again for helping me out...
