Wrote Raspberry Pi image to external drive, now stuck

#1 Post by sidneylopsides » 24 Feb 2016, 21:43

Hi,
I was writing a new image to an SD for my Raspberry Pi and selected the wrong drive letter.
I have a 1TB Seagate USB3 external drive that I use for my Lightroom catalogue, and that got the image.

When I look with Get Data Back I can see a 932GB NTFS filesystem and everything is there.
When I scan with Testdisk it is showing me a 56MB FAT16 and a 1000MB Linux partition.

I know the file system is intact, but I can't work out what I need to do to make it "live" again. In windows storage manager it shows a 932GB RAW.

Is there a way to reactivate the NTFS partition?

Thanks!

Run TestDisk, Analyse, Quick Search, Deeper Search, the NTFS partition should be listed.
Set this partition as P(rimary), on next screen, choose Write, confirm, BackupBS, confirm, Quit

Thank you for the reply. I've done this, and now I just have a single NTFS primary partition according to Testdisk, but windows still sees it as RAW. Have I missed something?

Fixed! I ran chkdsk /f on the drive and it's back as normal
