Windows 7: CHKDSK/f render my drive as RAW after trying to fix MFT bitmap...

Windows 7 Professional 32-bit SP1
CHKDSK/f render my drive as RAW after trying to fix MFT bitmap...

Yesterday, I was copying my old CD/DVD data into external HDD (acer easystore D110). Suddenly, the acer drive is not recognized. I replug the USB cable and windows ask to format it!
I plug it into another machine. I try UBuntu but it can't fix it but it tell me that "can't calculate free MFTs...". So I guess it's something to do with partition. I try TestDisk (TestDisk - CGSecurity). It found my partition but there are few large data that missing. My stupidity is that I should copy those data I WAS able to SEE then before do anything else. No, I did not. I continue to recover all at once.

So, I reboot the machine and chkdsk automatically run. It does its routine stuff. Everything went fine until it try to "fix master file table (MFT) bitmap attribute" and it takes forever. I left it run for 4 hours without knowing its progress. I break it (another stupidity). I boot back into 7 and run chkdsk/f. This is where disaster come!!!

First, it seems to do its thing (fixing stuff, showing progress...) then it goes to super long fixing MFT bitmap attribute. Now, I let it run overnight. In the morning, the process stop but give me error that "unable to fix master file table bitmap attribute :insufficient disk space". What the... ok I try to run it again but my machine sees the drive as RAW now!!!!! chkdsk won't run anymore

I try testdisk again.... so far, checking every sector but can't find my partition anymore...

Any help would be appreciated!!
