Failed to mount: mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error

Yesterday the power of my house went down. And when I started the OVM server I'm running on Vmware ESXI 5.5. I'm getting this message when I try to mount my drive under 'File Systems'.

Failed to mount '9cf4fb22-55c7-4eaa-94c7-a9a88aaaae59': mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error

Any help please? right now I'm loosing all my data because I was just copying everything to the server and I don't have a copy yet....
How can I fix this?

I'm running the command you gave me. Let see what happens. I'm crossing fingers.

What format would you recommend for my shared network drive with OMV? Ext4 instead of jfs? I just did it with jfs because I was reading online that they are pretty stable. But... now I experienced that they aren't haha.

I hope I can recover all my data.

If that command does not work? what would be another suggestion to recover my data? Could I plug it to a Linux distro and read it to recover the data?

I believe the plugin you mentioned will work if I can mount the HDD isn't?

I do have other HDD that I can use as backup. I had the intention of having something to backup but didn't get to that point. The accident happened before I could finish moving all my data. But I'll loose a lot if I cannot recover it

You know what!?

You saved my life!!!! It worked! Now that it works. Should I copy everything to another drive and change the format of my HDD? or I'll be ok with jfs?

I'm doing the plugin thing right now!

Thx! Thx! Thx!
