Partition/File Recovery

Preface:  This will teach me to study what I am doing before I do it....

Background Information:  I bought a Synology D209 and without thinking twice about it I placed the 2TB secondary drive from my Ubuntu (ext4) "Media Server" into the device.
The Synology D209 wrote some system and partition info to the drive. As I realized what was occurring, I attempted to cancel with no success.
I already spanked myself for assuming that the synology device would automatically read and mount my HD.  The D209 does not have the ability to read ext4 (not that that would help my case right now). I placed the HD back into the Ubuntu box hoping I could remount it and access my info.
No luck.  I looked at the HD with the Disk util and it says I have 2TB free.....

Question:  is there any way to recover the info I had on this drive?  I had 1.5TB of business files, music, and video.

Please help I am going to stress out soon.

So the drive is detected as free now, am I right?
Do you have Windows installed system so to connect this drive under it? Then I can recommend undelete tool that could help you.

Well, I don't know of any way to recover ext4 files. Maybe Ibas can help you (www.ibas.com).

"  Can I undelete files in Ext4?

No, in the same way that the ext3 journal requirements to be consistent after a crash prevent undelete of ext3 files, it isn't possible to undelete ext4 files. "

Noxcho:  No windows installations at all.  This was a secondary drive with no OS.  It contained all of my business and media files.

TobiasHolm:  I am trying very hard not to absorb what you are saying....  Are all of my files lost?


The drive was not formatted, system files were just written to it.  Could this cause all of my files to be lost?

No, probably your files are there, but I just don't know of any tool to recover ext4 files. I'm sure Ibas can recover the files if it's possible, but the charge quite some cash for this service. Anyway, maybe it's worth some $$$.

Or maybe somebody else know of a ext4 recovery tool?

Looks like a tool that can find lost ext4 partitions:

I haven't tested it though.

"TestDisk is a powerful free data recovery software! It was primarily designed to help recover lost partitions" Later versions of Testdisk support ext4:     http://www.cgsecurity.org/wiki/TestDisk

You can run it from sysrescuecd if needed:   http://www.sysresccd.org/Main_Page

I ended up purchasing the using R-Studio.  The ext4 recovery seems to work well.
I recovered 500GB out of 1500GB.  :(  Thanks for all of the help guys.

I researched the tools and settled on R-Studio.
I was able to retrieve about a third of what I lost, but that's what I get for being a fool.
R-Studio is a good solution.
