Hope I'm in the right place, I joined the forum for this post as it seems like an active community for data recovery.

I'm working on a drive for a friend... Apparently his wife completely filled it to the point that it won't mount anymore. I've pulled the 2.5 inch drive from it's enclosure and attached it to a computer to work on it. I tried a simple dd from my Ubuntu box to copy data to a larger drive in hopes that it would mount once it wasn't full anymore but have been running into errors about
Code:
exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock

and haven't been able to find a work around for that.

I've tried to run fsck but this is all I get:
Code:
sudo fsck /dev/sdb2
fsck from util-linux 2.27.1


I'm a little stumped at this point. I'm wondering if the original drive really is bad, at the beginning of my dd I was getting about 30MB/second and towards the end I was down to 6MB.

Any tips?

Hopefully
1. There isnt unusual noise coming from the drive.
2. There is no problems with the read/write heads
Can be a simple FW issue called slow response

Can you post a SMART report?

Some external enclosures are configured with 4KB sectors. If you remove the drive from such an enclosure and attach it to a SATA port on your motherboard, you expose its native 512e sectoring and render the file system inaccessible.

Can you show us the contents of sector 0?

FYI, it looks like this is not the only forum where the questions is being asked.

What is the full model of the drive ?

The model of the original enclosure might also be important. Some have hardware based encryption.
