testdisk says "no harddrive found"

#1 Post by Comissar » 31 Oct 2019, 23:35

I'm running Windows 10 v1809 with WSL and Ubuntu 18.0.4.

I need to restore one single undeleted file, my .bashrc in my home directory, which is in the Windows filesystem, i.e. /mnt/c/Users/sxw455/Ubuntu/ rather than /home/sxw455/.

Windows C is mounted as /mnt/c, and I have a flashdrive mounted as /mnt/d. I noticed that there is also a copy of C mounted as /c, but I don't know why.

testdisk, reports 'No harddisk found', but I can read all of the contents of C or D.

testdisk /mnt/c reports 'Unable to open file or device /mnt/c: Inappropriate ioctl for device'

fdisk -l reports 'fdisk: cannot open /proc/partitions: No such file or directory'

Running any of the commands as sudo or after unmounting the device gives the same results.

Any suggestions?

As you are under Windows, please run the Windows version of testdisk.
Note, under Linux, you should not run "testdisk 7.0-WIP" as it tried to open the device "7.0-WIP" but "sudo testdisk" (or testdisk as root).

Installed testdisk_win and ran it, selected 'Create a new log file', and /dev/sda (my 256GB C drive). I also have /dev/sdb (a 16GB flash drive). Then I selected 'EFI GPT,' as that was what testdisk detected, and 'Advanced'.

I've now got 5 partitions listed; 'MS Data' and 'Basic data partition' looks to be my C drive, at 238GB, so I selected that. Under 'Type', 'MS Data', I selected 'NTFS', and went to undelete, and it said 'Can't open file system. File system seems damaged'. Now there is nothing wrong with the file system, I'm just trying to recover a single deleted file. For grins, I tried FAT32 and FAT16, but got the same message.

What am I missing?

Thanks,
