I need some help recover files from a partially overwritten partition.
I will start with what happened. I was trying to make a image out of my hard drive using dd
, but I found somewhere online that using pv
would tell me the best bs count to make the copy, what it didn't say was that it would make the copy.
I ran the following command:
pv < /dev/sda > /dev/sdc
When I realized what was going on I stopped it, but it had already written around 1GB. I would like to recover the files that were not written over, I suspect those that were are long gone.
If someone knows a way I would be thankful.

There is no 100% satisfactory solution to your problem right now, only workarounds. and the one resource that is going to help you now is testdisk. Furthermore, there is really only one thing I can advise you now: stop writing to the disk, preferably take a clone and work from the clone.
Why? Well if someone comes up with a better idea then
testdisk
, you can start the process over again with a fresh clone!For the future:
dd
is the abbreviation of Disk Destroyer.
