Post the output of zpool status. Please use CODE tags or Pastebin.

Also, your hardware and FreeNAS version, please, as per the forum rules.

Sorry for my ignorance I'm fairly new to this and I would like to ask where do I find this info?

You need to go to the shell/console and execute the command: zpool status

Copy/paste the results into code tags (found on the insert icon in the message editor) here, or use pastebin.com and post the link to the information.

While the information you listed is a start, we'd also like to know more about your disks, mobo, etc. See the forum rules in red at the top of the page.

Note, you're only using 1/2 the required amount of RAM.

I have to also tell you another person told me to detach the bad volume yesterday and I did now it only see the small volume I had. Data100G was the other volume.
Drives are 3 (500gigs) one drive died when surge hit, 1 (1tb) and 2 (2tb) on a gigabite M/B. The pool D500gb is one 500 gb drive.

Code:

[root@freenasServer ~]# zpool status                                           
  pool: D500gb

I'm a bit confused by your description about the drives and what you were told to do. It would have been better to ask the question here first, rather than take bad advice.

Are you saying that you have/had 6 drives in the server, ie. 3x500Gb, 1x1Tb, and 2x2Tb? And, pool D500gb is a single 500Gb drive.

Were all the other striped together (akin to RAID0) in a single pool (Data100G)? If so, that's a dangerous configuration. If you loose one drive, like you did, you loose all the data.

Most users use some form of RAIDz, for example, you could have put 3x500Gb drives in a RAIDz volume. If one failed, the data would still be accessible. One could offline the bad disk and replace it.
