Firstly, sorry if this isn't the right forum. I hope despite that, someone can help me out.
I have here a Seagate 3TB external USB drive that is now seen as RAW. It has around 2.8 TB of data I'd like to have back. Failing that, I'd love to at least retrieve my photos folder and iTunes library from it (all those years of carefully curated playlists. Why do so few of us take data backup seriously? Never again!)
I was recording a video from OBS to this drive the other day and OBS crashed. Now I don't know anymore the exact reason why I took the power cable out the USB drive - though I did know that some of my USB cables were not in ideal slots so maybe this was part of my reasoning. Anyhow, after days of Google searches I realise I did wrong and should have used the "Safely Remove Hardware" feature. Oh well.
Plugging the disk back in and it listed as unallocated on Disk Management. I downloaded SeaTools and did a short generic scan (Fail) then a long scan (Pass). But somewhere along the line my main Windows 10 computer now cannot see the drive at all. So I tried it on my Windows 7 netbook and it does see the drive. If it's a lucky day, I can even see the folders on the drive when I double click on it. But usually it hangs when I try to do that and never reveals the data.
I tried TestDisk and all seemed well - though a predicted 3-4 days to get through the scan. By about 20% it seems multiple errors had made a gigantic log file that clogged up my poor little Windows 7 netbook so I had to end the scan early.
From some search results, I had this idea that maybe I could use something like MBRWizard to rebuild the MBR but it would not write to a RAW drive.
Meanwhile now when I plug the drive back into my Win10 machine, it still refuses to see it. So for the moment everything is being done via the Win7 machine, which is very slow and fiddly with its tiny little keyboard!
One search result suggested I used diskpart to change the drive letter (currently F:) to another one, which might then enable me to run CHKDSK on it (currently it refuses to - hangs for ages, and I think last time I tried it came back with a message that it can't do CHKDSK on RAW drives). But when I run diskpart it hangs and won't even get to the DISKPART> prompt. If I unplug the USB drive, the DISKPART> prompt appears. If I then plug the drive back in and give Windows a chance to notice it, then type "list volume" it hangs again.
Now I am aware I could send this drive to a data recovery service, but: as a stubborn English speaker in France I am a little put off contacting French data recovery companies because I am so embarassed I don't speak the beautiful French language well enough. Also, I did try for a quote on one French site, and it came back suggesting a minimum of 250 euros. Might seem like nothing to some people but I am currently between jobs and wanting to be very frugal with my cash. Also, a brand new drive costs about the same, but of course I do value the data otherwise I wouldn't be trying all this. I could, possibly, be convinced to try a data recovery company, but I'd like to know if there's other options I could try first.
I'm also aware of some thoughts of taking the drive out of the casing - and I have recently rebuild the innards of my computer with a new MB, CPU...etc so I am not completely freaked out by that idea but it does make me a little nervous. Also, I'd need to get some cables to connect it inside my PC?
I'm pretty tech savvy but this is new ground for me and I'm thus a very willing and able newbie. So sorry for the big dump of information but hopefully you'll appreciate a little advance info so you can get a good picture of what's going on.
Anyhow, I've a tendency to write a lot, so I will end it here but just to say thanks in advance to anyone who can offer me any help.
