Hi,

I've had an issue with data recovery for two of my drives, recently. My first drive is my SD card, accidentally formatted from PAL to NTSC, losing all of my camera footage which I know was idiotic.

My second drive was my 3TB Samsung external HDD. I'm not sure what happened, maybe the power was pulled or something but I booted up windows and wasn't able to access it anymore. I do YouTube so I have all of my recordings, music etc. on there. Ironically, I had ordered a new 3TB HDD to back it up if anything was to happen to it and this happened THE DAY BEFORE my new one arrived. Gutted!

Now I'm trying to use my new 3TB drive to recover my old HDD. I took the old Samsung drive out of its enclosure and plugged it directly into the PC (windows still tells me to format it which I won't do). I came across an application called TestDisk which I'm not entirely sure how to use. I don't mind if it takes days to rebuild my HDD, as long as I can get everything or almost everything back (the drive was pretty full).

I did open up TestDisk and going through it where you usually are supposed to be able to copy files across onto a new HDD, I got the message "Can't open filesystem. Filesystem seems damaged". In Windows disk management, I'm still assigned the letter E, but it's labelled as a "RAW" drive. Does this mean I've lost my partition, my partition was deleted or something around that area?

What's the likelihood I can recover my information off my drive? Can someone help guide me through how to use this software? I just want to rebuild and clone my old data onto my new drive.

Currently I am analysing my disk. It says this:

Disk /dev/sda - 3000 GB / 2794 GiB - CHS 364801 255 63
Analyse cylinder 29213/364800: 08%
Read error at 65/36/36 (lba=1046528)

It's been about 20 minutes and I'm wondering what to do next. Here are some links that are relevant to me:
