3TB external drive became RAW

#1 Post by oyvdei » 23 Jul 2015, 15:33

Hello, please I'm in need for some help.

I got an Seagate expansion external drive with 3TB. A little time ago, the USB 3.0 port got broken, so I bought a new enclosure with a new connector from another manufacturer. When I connected it to my computer, I couldn't get access and Windows wanted me to format the drive. The drive was visible in Windows though, as station (F:) as before, but with no other info. When I ran chkdsk, it said it had became RAW and couldn't do anything.

I got a tip from a friend to try TestDisk. I read a lot on this board to get a hang of what I had to do. After Create, I saw the drive as "Disk /dev/sdb - 3000 GB/2794 GiB". I chose Intel then Analyse and Quick Search. After that, I couldn't see my files and folders in List, just some other stuff, so I ran Deep Search.

When the Deep Search was finished after many hours, I went in the partition I thought was right (I wasn't able to see a List with files here). In the hope of fixing the problem, I probably hesitated a bit and didn't exactly knew what I was doing. I chose Write and rebooted.

Now, Windows don't recognize the drive anymore, it is not visible. It's still visible in TestDisk though, so I try again now.

I take screenshots this time as seen below, as the same with the file log. Can you see from this if I still can recover my drive? I have many valuable files on it I don't want to lose.

The test_logical error didn't show the first time I tried before I wrote the partition the first time.

And this is the result after Quick Search. I'm currently running the Deep Search now. So far it reports about an invalid FAT boot sector.

Can it be I have to change something in the disk geometry?

Following is the log file prior to the Quick Search:

Hi. I'm still stuck right where I was..

I am in fact able to access my files with another data recovery program. But to save my files that way and then format my drive, will be a very twisted and time consuming process for me.
I'll be very happy if there is a way to repair and recover my partition(s) with TestDisk, so I once again can get directly access to all my files without formatting the drive :)

Sry for late.
TestDisk Deeper Search might be time consuming too.
But it would be necessary to run and find your lost partition.
Your current partition table only contain an extended partition and a FAT16-Partition which is probably wrong.
Looks like that you aborted Deeper Search:

Hi again, and thanks for your reply.
I had in fact run Deeper Search a couple of times when I made this topic, but I messed up the log file, I guess.

Anyway, I still haven't got any further with my lost partition. I'm starting to think I have to manually add a partition or change something with the disk geometry.
But I don't know, so any further help is much appreciated.

I ran Deeper Search again, and here is my current log file:

Hi Fiona. As mentioned in my previously reply, I ran Deeper Search properly as you requested. Is there anything in my log file that can help identify the issue with the partitions?

oh my friend I am in the same boat as you. I think our problem was using the wrong kind of enclosure. I might of used one that could not handle 3TB, I read somewhere this can cause read issues. Just try to run Photorec dude, see if you can backup your files and then just format the drive and reupload your stuff. Stop using the enclosure, plug the HDD into your computer (if you have a desktop). Im currently using the Photorec tutorial and i see all my files popping up again. I ran chkdsk too after I changed the enclosure, fkd the HDD lol. Damn you windows!
