Hi,
Let me put it this way : when you will have read the page with the testdisk howto, you will want to have it in front of you in another machine while trying to get back the lost partition. If you succeed in finding it, next step will bring you to erase what you just did last, and which caused the lost of the partition.
If you succeed and boot again to the former system, and regain therefore access to that /home partition, then you will be able to copy the datas, or the partition to another media.
You have to consider it as as last chance to recover lost data.
There is another possibility I have thought about : maybe your partition is still there and just covered by the new mount point. If this the case, you wouldn't need to use testdisk. To check if this is the case, this time you could visit the hard drive from within a live cd or live usb.
